128-493: Canebrakes were formerly widespread in the Southern United States , potentially covering 10,000,000 acres (4,000,000 ha), The presence of canebrakes signaled to Native Americans and to early European settlers that an area was fertile and ecologically rich. The canebrakes were a striking feature of the landscape to the earliest European explorers, who remarked upon how densely the cane grew and how difficult it

256-419: A symbiotic union of a fungus and photosynthetic algae or cyanobacteria , reproduce through fragmentation to ensure that new individuals contain both symbionts. These fragments can take the form of soredia , dust-like particles consisting of fungal hyphae wrapped around photobiont cells. Clonal Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning where an organism

384-497: A chemical cue accumulates and induces the transition to sexual reproduction. Many protists and fungi alternate between sexual and asexual reproduction. A few species of amphibians, reptiles, and birds have a similar ability. The slime mold Dictyostelium undergoes binary fission (mitosis) as single-celled amoebae under favorable conditions. However, when conditions turn unfavorable, the cells aggregate and follow one of two different developmental pathways, depending on conditions. In

512-414: A fertilization event. These haploid individuals produce gametes through mitosis . Meiosis and gamete formation therefore occur in separate multicellular generations or "phases" of the life cycle, referred to as alternation of generations . Since sexual reproduction is often more narrowly defined as the fusion of gametes ( fertilization ), spore formation in plant sporophytes and algae might be considered

640-418: A form of asexual reproduction (agamogenesis) despite being the result of meiosis and undergoing a reduction in ploidy . However, both events (spore formation and fertilization) are necessary to complete sexual reproduction in the plant life cycle. Fungi and some algae can also utilize true asexual spore formation, which involves mitosis giving rise to reproductive cells called mitospores that develop into

768-567: A functionally similar manner by mitosis ; most of these are also capable of sexual reproduction. Multiple fission at the cellular level occurs in many protists , e.g. sporozoans and algae . The nucleus of the parent cell divides several times by mitosis , producing several nuclei. The cytoplasm then separates, creating multiple daughter cells . In apicomplexans , multiple fission, or schizogony appears either as merogony , sporogony or gametogony . Merogony results in merozoites , which are multiple daughter cells, that originate within

896-593: A large American army in the process, and set up a network of bases inland. Although there were Loyalists within the Southern colonies, they were concentrated in larger coastal cities and were not great enough in number to overcome the revolutionaries. The British forces at the Battle of Monck's Corner and the Battle of Lenud's Ferry consisted entirely of Loyalists with the exception of the commanding officer ( Banastre Tarleton ). Both white and black Loyalists fought for

1024-718: A large area north of the city (along the Mississippi) becoming known as the German Coast. Still greater numbers immigrated to Texas (especially after 1848), where many bought land and were farmers. Many more German immigrants arrived in Texas after the Civil War, where they created the brewing industry in Houston and elsewhere, became grocers in numerous cities, and also established wide areas of farming. By 1840, New Orleans

1152-564: A male gamete. Examples are parthenogenesis and apomixis . Parthenogenesis is a form of agamogenesis in which an unfertilized egg develops into a new individual. It has been documented in over 2,000 species. Parthenogenesis occurs in the wild in many invertebrates (e.g. water fleas, rotifers , aphids, stick insects , some ants, bees and parasitic wasps) and vertebrates (mostly reptiles, amphibians, and fish). It has also been documented in domestic birds and in genetically altered lab mice. Plants can engage in parthenogenesis as well through

1280-415: A mate becomes difficult. For example, female zebra sharks will reproduce asexually if they are unable to find a mate in their ocean habitats. Parthenogenesis was previously believed to rarely occur in vertebrates, and only be possible in very small animals. However, it has been discovered in many more species in recent years. Today, the largest species that has been documented reproducing parthenogenically

1408-440: A naval flotilla was sent to Charleston harbor, and the threat of landing ground troops was used to compel the collection of tariffs. A compromise was reached by which the tariffs would be gradually reduced, but the underlying argument over states' rights continued to escalate in the following decades. The second issue concerned slavery, primarily the question of whether slavery would be permitted in newly admitted states. The issue

1536-429: A new organism after dispersal. This method of reproduction is found for example in conidial fungi and the red algae Polysiphonia , and involves sporogenesis without meiosis. Thus the chromosome number of the spore cell is the same as that of the parent producing the spores. However, mitotic sporogenesis is an exception and most spores, such as those of plants and many algae, are produced by meiosis . Fragmentation

1664-402: A phenomenon known as "egg parasitism." This method of reproduction has been found in several species of the clam genus Corbicula , many plants like, Cupressus dupreziana , Lomatia tasmanica , Pando and recently in the fish Squalius alburnoides . Other species where androgenesis has been observed naturally are the stick insects Bacillus rossius and Bassillus Grandii ,

1792-538: A process called apomixis . However this process is considered by many to not be an independent reproduction method, but instead a breakdown of the mechanisms behind sexual reproduction. Parthenogenetic organisms can be split into two main categories: facultative and obligate. In facultative parthenogenesis, females can reproduce both sexually and asexually. Because of the many advantages of sexual reproduction, most facultative parthenotes only reproduce asexually when forced to. This typically occurs in instances when finding

1920-402: A process called thelytoky . The freshwater crustacean Daphnia reproduces by parthenogenesis in the spring to rapidly populate ponds, then switches to sexual reproduction as the intensity of competition and predation increases. Monogonont rotifers of the genus Brachionus reproduce via cyclical parthenogenesis: at low population densities females produce asexually and at higher densities

2048-459: A short time during Reconstruction. There were thousands of people on the move, as African Americans tried to reunite families separated by slave sales, and sometimes migrated for better opportunities in towns or other states. Other freed people moved from plantation areas to cities or towns for a chance to get different jobs. At the same time, whites returned from refuges to reclaim plantations or town dwellings. In some areas, many whites returned to

2176-525: A sperm cell is used to initiate reproduction. However, the sperm's genes never get incorporated into the egg cell. The best known example of this is the Amazon molly . Because they are obligate parthenotes, there are no males in their species so they depend on males from a closely related species (the Sailfin molly ) for sperm. Apomixis in plants is the formation of a new sporophyte without fertilization. It

2304-520: A total of 260,000, out of a total white Southern population at the time of around 5.5 million. Based on 1860 census figures, 8% of all white males aged 13 to 43 died in the war, including 6% in the North and about 18% in the South. Northern military deaths were greater than Southern military deaths in absolute numbers, but were two-thirds smaller in terms of proportion of the population affected. After

2432-458: A trail through them. However, as European settlers came, the cane gradually disappeared as it was used as high-quality forage for livestock that was available all year round. Pigs in particular destroyed canebrakes rapidly by rooting up their underground rhizomes, and the settlers intentionally used pigs to clear out canebrakes so they could be converted to agricultural land. The absence of the controlled burns used by Native Americans to maintain

2560-400: A year. This switch is triggered by environmental changes in the fall and causes females to develop eggs instead of embryos. This dynamic reproductive cycle allows them to produce specialized offspring with polyphenism , a type of polymorphism where different phenotypes have evolved to carry out specific tasks. The cape bee Apis mellifera subsp. capensis can reproduce asexually through

2688-548: Is a form of asexual reproduction where a new organism grows from a fragment of the parent. Each fragment develops into a mature, fully grown individual. Fragmentation is seen in many organisms. Animals that reproduce asexually include planarians , many annelid worms including polychaetes and some oligochaetes , turbellarians and sea stars . Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation, such as gemmae in mosses and liverworts . Most lichens , which are

2816-559: Is a type of asexual reproduction found in plants where new individuals are formed without the production of seeds or spores and thus without syngamy or meiosis . Examples of vegetative reproduction include the formation of miniaturized plants called plantlets on specialized leaves, for example in kalanchoe ( Bryophyllum daigremontianum ) and many produce new plants from rhizomes or stolon (for example in strawberry ). Some plants reproduce by forming bulbs or tubers , for example tulip bulbs and Dahlia tubers. In these examples, all

2944-471: Is a widespread form of asexual reproduction in animals, whereby the fertilized egg or a later stage of embryonic development splits to form genetically identical clones. Within animals, this phenomenon has been best studied in the parasitic Hymenoptera . In the nine-banded armadillos , this process is obligatory and usually gives rise to genetically identical quadruplets. In other mammals, monozygotic twinning has no apparent genetic basis, though its occurrence

3072-413: Is an accepted version of this page Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes . The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent and thus the newly created individual is genetically and physically similar to

3200-402: Is common. There are at least 10 million identical human twins and triplets in the world today. Bdelloid rotifers reproduce exclusively asexually, and all individuals in the class Bdelloidea are females. Asexuality evolved in these animals millions of years ago and has persisted since. There is evidence to suggest that asexual reproduction has allowed the animals to evolve new proteins through

3328-418: Is derived entirely from pollen . Androgenesis occurs when a zygote is produced with only paternal nuclear genes . During standard sexual reproduction , one female and one male parent each produce haploid gametes (such as a sperm or egg cell, each containing only a single set of chromosomes ), which recombine to create offspring with genetic material from both parents. However, in androgenesis, there

3456-414: Is important in ferns and in flowering plants, but is very rare in other seed plants. In flowering plants, the term "apomixis" is now most often used for agamospermy , the formation of seeds without fertilization, but was once used to include vegetative reproduction . An example of an apomictic plant would be the triploid European dandelion . Apomixis mainly occurs in two forms: In gametophytic apomixis,

3584-540: Is interest in finding out how to restore them. Canebrakes have been found to provide habitat for the following rare plants: Canebrakes are considered a critically endangered ecosystem by many biologists, but they have been studied very little. Southern Illinois University conducts some ongoing research on restoring canebrakes. There is also a great interest among the Eastern Band of Cherokee Indians and other regional tribal nations to restore canebrakes, to preserve

3712-766: Is no recombination of maternal and paternal chromosomes, and only the paternal chromosomes are passed down to the offspring (the inverse of this is gynogenesis , where only the maternal chromosomes are inherited, which is more common than androgenesis). The offspring produced in androgenesis will still have maternally inherited mitochondria , as is the case with most sexually reproducing species. Androgenesis occurs in nature in many invertebrates (for example, clams, stick insects, some ants, bees, flies and parasitic wasps ) and vertebrates (mainly amphibians and fish ). The androgenesis has also been seen in genetically modified laboratory mice. One of two things can occur to produce offspring with exclusively paternal genetic material:

3840-417: Is only found in 11 sites in just two counties of the state of Alabama . Cane can propagate itself rapidly through asexual reproduction, allowing it to persist quietly in the shade of a forest for years and rapidly take advantage of disturbance such as wildfire. Historically, canebrakes were maintained by Native Americans using controlled burns . The fire would burn the aboveground part of the plant but leave

3968-667: Is relatively rare among multicellular organisms , particularly animals . It is not entirely understood why the ability to reproduce sexually is so common among them. Current hypotheses suggest that asexual reproduction may have short term benefits when rapid population growth is important or in stable environments, while sexual reproduction offers a net advantage by allowing more rapid generation of genetic diversity, allowing adaptation to changing environments. Developmental constraints may underlie why few animals have relinquished sexual reproduction completely in their life-cycles. Almost all asexual modes of reproduction maintain meiosis either in

4096-441: Is split into fragments. Each of these fragments develop into mature, fully grown individuals that are clones of the original organism. In echinoderms , this method of reproduction is usually known as fissiparity . Due to many environmental and epigenetic differences, clones originating from the same ancestor might actually be genetically and epigenetically different. Agamogenesis is any form of reproduction that does not involve

4224-525: Is the Komodo dragon at 10 feet long and over 300 pounds. Heterogony is a form of facultative parthenogenesis where females alternate between sexual and asexual reproduction at regular intervals (see Alternation between sexual and asexual reproduction ). Aphids are one group of organism that engages in this type of reproduction. They use asexual reproduction to reproduce quickly and create winged offspring that can colonize new plants and reproduce sexually in

4352-558: The 15th Amendment (which extended the right to vote to African American males), African Americans in the South were made free citizens and were given the right to vote. Under Federal protection, white and black Republicans formed constitutional conventions and state governments. Among their accomplishments were creating the first public education systems in Southern states, and providing for welfare through orphanages, hospitals and similar institutions. Northerners came south to participate in politics and business. Some were representatives of

4480-609: The British Isles before the American Revolution . In the 1980 census , 34% of Southerners reported that they were of English ancestry; English was the largest reported European ancestry in every Southern state by a large margin. The early colonists engaged in warfare , trade, and cultural exchanges. Those living in the backcountry were more likely to encounter Creek Indians , Cherokee , and Choctaws and other regional native groups. The oldest university in

The last region to be settled was Appalachia, also settled by the Scotch-Irish . King Charles II of England granted the Charter of Carolina in 1663 for land south of the British Colony of Virginia and north of Spanish Florida . He granted the land to eight lords proprietor . Charles granted

4736-495: The Civil War and Reconstruction era (1865–1877). Following effects included thousands of lynchings (mostly from 1880 to 1930), a segregated system of separate schools and public facilities established from Jim Crow laws that remained until the 1960s, and the widespread use of poll taxes and other methods to deny black and poor people the ability to vote or hold office until the 1960s. Scholars have characterized pockets of

4864-501: The Democratic Party to power. In 1876 white Democrats regained power in most of the state legislatures. They began to pass laws designed to strip African Americans and Poor Whites from the voter registration rolls. The success of late-19th century interracial coalitions in several states inspired a reaction among some white Democrats, who worked harder to prevent both groups from voting. Asexual reproduction This

Some were adventurers who hoped to benefit themselves by questionable methods. They were all condemned with the pejorative term of carpetbagger . Some Southerners would also take advantage of the disrupted environment and made money off various schemes, including bonds and financing for railroads. White Southerners who supported Reconstruction policies and efforts became known as scalawags . Secret vigilante organizations such as

5120-552: The Ku Klux Klan  – an organization sworn to perpetuate white supremacy  – had arisen quickly after the war's end in the 1860s, and used lynching , physical attacks, house burnings and other forms of intimidation to keep African Americans from exercising their political rights. Although the first Klan was disrupted by prosecution by the Federal government in the early 1870s, other groups persisted. By

Bdelloid rotifers are extraordinarily resistant to damage from ionizing radiation due to the same DNA-preserving adaptations used to survive dormancy. These adaptations include an extremely efficient mechanism for repairing DNA double-strand breaks. This repair mechanism was studied in two Bdelloidea species, Adineta vaga , and Philodina roseola . and appears to involve mitotic recombination between homologous DNA regions within each species. Molecular evidence strongly suggests that several species of

In 1780 and 1781, the British largely halted reconquest of the northern states and concentrated on the south, where they were told there was a large Loyalist population ready to leap to arms once the royal forces arrived. The British took control of Savannah and Charleston, capturing

It is between the Atlantic Ocean and the Western United States , with the Midwestern and Northeastern United States to its north and the Gulf of Mexico and Mexico to its south. Historically, the South was defined as all states south of

5632-596: The United States Census Bureau , A survey conducted by social geographers in 2010 selected thirteen states as the cultural south; Mississippi, Alabama, Louisiana, Arkansas, Georgia, Kentucky, North Carolina, South Carolina, Tennessee, Florida, Virginia, West Virginia, and Oklahoma. The Southern region of the United States includes sixteen states. As of 2010, an estimated 114,555,744 people, or thirty seven percent of all U.S. residents, lived in

The question of how to define the boundaries and subregions in the South has long been the focus of research and debate. As defined by

5888-491: The hammerhead shark and the blacktip shark . In both cases, the sharks had reached sexual maturity in captivity in the absence of males, and in both cases the offspring were shown to be genetically identical to the mothers. The New Mexico whiptail is another example. Some reptiles use the ZW sex-determination system , which produces either males (with ZZ sex chromosomes) or females (with ZW or WW sex chromosomes). Until 2010, it

6016-431: The rotifer Brachionus calyciflorus asexual reproduction (obligate parthenogenesis ) can be inherited by a recessive allele, which leads to loss of sexual reproduction in homozygous offspring. Inheritance of asexual reproduction by a single recessive locus has also been found in the parasitoid wasp Lysiphlebus fabarum . Asexual reproduction is found in nearly half of the animal phyla. Parthenogenesis occurs in

6144-531: The south-central and southeastern states. For example, California, which is geographically in the southwestern part of the country, is not considered part of the South. However, the geographically southeastern state of Georgia is. The South, being home to some of the most racially diverse areas in the United States, is known for having developed its own distinct culture , with different customs, fashion, architecture , musical styles , and cuisines , which have distinguished it in many ways from other areas of

6272-457: The stick insect genus Timema have used only asexual (parthenogenetic) reproduction for millions of years, the longest period known for any insect. Similar findings suggest that the mite species Oppiella nova may have reproduced entirely asexually for millions of years. In the grass thrips genus Aptinothrips there have been several transitions to asexuality, likely due to different causes. A complete lack of sexual reproduction

6400-606: The 16th century, reaching a peak in the late 17th century, but the population was small because the Spaniards were relatively uninterested in agriculture, and Florida had no mineral resources. There were regional differences in the Southern colonies, with the three main regions of Tidewater , the Deep South , and Appalachia . The first region to be settled was Tidewater, containing the low-lying plains of southeast Virginia , northeastern North Carolina , southern Maryland and

6528-621: The 18th-century Mason–Dixon line , the Ohio River , and 36°30′ parallel . Within the South are different subregions such as the Southeast , South Central , Upper South , and Deep South . Maryland , Delaware , Washington, D.C. , and Northern Virginia have become more culturally, economically, and politically aligned in certain aspects with the Northeastern United States and are sometimes identified as part of

6656-741: The British Governor Dunmore of Virginia's promise of freedom for service. Many others were removed by Loyalist owners and became slaves elsewhere in the British Empire. Between 1770 and 1790, there was a sharp decline in the percentage of blacks – from 61% to 44% in South Carolina and from 45% to 36% in Georgia. In addition, some slaveholders were inspired to free their slaves after the Revolution. They were moved by

6784-737: The British Navy. The British Navy did arrive, but so did a stronger French fleet, and Cornwallis was trapped. American and French armies, led by George Washington, forced Cornwallis to surrender his entire army in Yorktown, Virginia in October 1781, effectively winning the North American part of the war. The Revolution provided a shock to slavery in the South and other regions of the new country. Thousands of slaves took advantage of wartime disruption to find their own freedom, catalyzed by

6912-637: The British at the Battle of Kemp's Landing in Virginia. Led by Nathanael Greene and other generals, the Americans engaged in Fabian tactics designed to wear down the British invasion force and to neutralize its strong points one by one. There were numerous battles large and small, with each side claiming some victories. By 1781, however, British General Cornwallis moved north to Virginia, where an approaching army forced him to fortify and await rescue by

7040-697: The Census definition, two U.S. territories located southeast of Florida ( Puerto Rico and the U.S. Virgin Islands ) are sometimes included as part of the Southern United States. The Federal Aviation Administration includes Puerto Rico and the U.S. Virgin Islands as part of the South, as does the Agricultural Research Service and the U.S. National Park Service . The first well-dated evidence of human occupation in

In 2023, the United Keetoowah Band of Cherokee Indians in Oklahoma co-hosted the first Rivercane Gathering in Tahlequah, Oklahoma with the U.S. Forestry Service, an educational event to unite traditional tribal experts and artisans with various researchers and landholders for the continued preservation of canebrakes. Southern United States The Southern United States (sometimes Dixie , also referred to as

7296-479: The Civil War, the South was devastated in terms of infrastructure and economy. Because of states' reluctance to grant voting rights to freedmen, Congress instituted Reconstruction governments. It established military districts and governors to rule over the South until new governments could be established. Many white Southerners who had actively supported the Confederacy were temporarily disenfranchised. Rebuilding

7424-553: The Confederacy. Though early in the war, the Confederacy controlled more than half of Kentucky and the southern portion of Missouri. By March 1862, the Union largely controlled all the border state areas, had shut down all commercial traffic from all Confederate ports, had prevented European recognition of the Confederate government, and was poised to seize New Orleans. The rugged mountainous East Tennessee region attempted to rejoin

7552-642: The East Coast to the Great Lakes. Some noted explorers who encountered and described the Mississippian culture, by then in decline, included Pánfilo de Narváez (1528), Hernando de Soto (1540), and Pierre Le Moyne d'Iberville (1699). Native American descendants of the mound-builders include Alabama , Apalachee , Caddo , Cherokee , Chickasaw , Choctaw , Creek , Guale , Hitchiti , Houma , and Seminole peoples, all of whom still reside in

7680-586: The Mississippi River in 1863. In the East, however, the Confederate Army under Robert E. Lee beat off attack after attack in its defense of their capital at Richmond. But when Lee tried to move north, he was repulsed (and nearly captured) at Sharpsburg (1862) and Gettysburg (1863). The Confederacy had the resources for a short war, but was unable to finance or supply a longer war. It reversed

7808-471: The Northeast or Mid-Atlantic . The United States Census Bureau continues to define all four places as formally being in the South. To account for cultural variations across the region, some scholars have proposed definitions of the South that do not coincide neatly with state boundaries. The South does not precisely correspond to the entire geographic south of the United States, but primarily includes

By 1856, the South had lost control of Congress, and was no longer able to silence calls for an end to slavery – which came mostly from the more populated, free states of the North. The Republican Party, founded in 1854, pledged to stop the spread of slavery beyond those states where it already existed. After Abraham Lincoln

8064-518: The South generally has a reputation as hot and humid, with long summers and short, mild winters. Most of the South—except for the areas of higher elevations and areas near the western, southern, and some northern fringes—falls in the humid subtropical climate zone. Crops grow readily in the South due to its climate consistently providing growing seasons of at least six months before the first frost. Some common environments include bayous and swamplands,

8192-445: The South include: Historically, the South was defined as all states south of the 18th century Mason–Dixon line , the Ohio River , and 36°30′ parallel . Newer definitions of the South today are harder to define, due to cultural and sub-regional differences throughout the region; however, definitions usually refer to states that are in the southeastern and south central geographic region of the United States. Although not included in

The Census Bureau defined three smaller divisions: The Council of State Governments , an organization for communication and coordination between states, includes in its South regional office the states of Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia and West Virginia. Other terms related to

Other peoples whose ancestral links to the Mississippian culture are less clear, but those who were in the region before the European incursion include the Catawba and the Powhatan . The arrival of European settlers caused a massive population decline in Native Americans , due to Europeans unknowingly spreading diseases that the natives had no immunities towards, numerous violent conflicts, and forcibly relocating them.

In South Carolina, the Chattooga Conservancy has formed a collaboration with the Eastern Band of the Cherokee and the USDA Forest Service to restore 29 acres of canebrake. Revitalization of Traditional Cherokee Artisan Resources (RTCAR) has also coordinated the restoration of river cane on a 109-acre site in North Carolina . This restoration area will include educational signage in

9216-547: The Union as a new state , having opposed secession and slavery compared to most of Tennessee. In the four years of war 1861–65 the South was the primary battleground, with all but two of the major battles taking place on Southern soil. Union forces led numerous campaigns into the western Confederacy, controlling the border states in 1861, the Tennessee River, the Cumberland River and New Orleans in 1862, and

9344-639: The United States. From 1860 to 1861, eleven Southern states plus an additional two Southern states that were claimed and partially controlled seceded from the Union , forming the Confederate States of America . Following the American Civil War , these states were subsequently added back to the Union. Sociological research indicates that Southern collective identity stems from political, historical, demographic, and cultural distinctiveness from

9472-411: The arguments over states' rights that culminated in secession and the Civil War. One of these issues concerned the protective tariffs enacted to assist the growth of the manufacturing sector, primarily in the North. In 1832, in resistance to federal legislation increasing tariffs, South Carolina passed an ordinance of nullification , a procedure in which a state would, in effect, repeal a Federal law. Soon

Other species considered canebrake specialists include as many as seven moth species and five known butterfly species dependent on Arundinaria bamboos as a host plant, and Swainson's warbler ( Limnothlypis swainsonii ). Swainson's warbler has recently been found to use pine plantations (widespread across the Southeastern United States) of a particular age, as they may provide

Destruction of habitat for development and construction is also implicated as a cause of the decline by the Choctaw Nation . This destruction has impacted a number of species. The survival of the Florida panther ( Puma concolor couguar ) has been challenged, and Bachman's warbler ( Vermivora bachmanii ) has probably become extinct . The extinct Carolina parakeet ( Conuropsis carolinensis) also depended on canebrakes, and their demise may have been hastened by

In the mid-to-late-18th century, large groups of Ulster Scots (later called the Scotch-Irish ) and people from the Anglo-Scottish border region immigrated and settled in the back country of Appalachia and the Piedmont . They were the largest group of non-English immigrants from

9984-590: The crucial roles the plant plays in Cherokee culture and to stop the art of river cane basket weaving from dying out. The various insect species that are Arundinaria specialists are at risk due to their sensitivity to habitat fragmentation. A major obstacle to restoring canebrakes is the reproductive habits of Arundinaria bamboos; Arundinaria typically reproduces asexually using rhizomes, forming clonal colonies that spread outward. The plant only flowers every few decades, and usually dies after flowering; additionally, seeds are often not viable. Therefore, propagating

10112-581: The eleven Confederate states, states such as Tennessee (especially East Tennessee ), Virginia (which included West Virginia at the time), and North Carolina were home to the largest populations of Unionists. Many areas of Southern Appalachia harbored pro-Union sentiment as well. As many as 100,000 men living in states under Confederate control would serve in the Union Army or pro-Union guerrilla groups. Although Southern Unionists came from all classes, most differed socially, culturally, and economically from

10240-487: The embryo arises from an unfertilized egg within a diploid embryo sac that was formed without completing meiosis. In nucellar embryony , the embryo is formed from the diploid nucellus tissue surrounding the embryo sac. Nucellar embryony occurs in some citrus seeds. Male apomixis can occur in rare cases, such as in the Saharan Cypress Cupressus dupreziana , where the genetic material of the embryo

10368-553: The end of the 15th century – the Mississippian culture . The Mississippian culture was a complex, mound-building Native American culture that flourished in what is now the Southeastern United States from approximately 800 AD to 1500 AD. Natives had elaborate and lengthy trading routes connecting their main residential and ceremonial centers extending through the river valleys and from

10496-438: The fall to lay eggs for the next season. However, some aphid species are obligate parthenotes. In obligate parthenogenesis, females only reproduce asexually. One example of this is the desert grassland whiptail lizard , a hybrid of two other species. Typically hybrids are infertile but through parthenogenesis this species has been able to develop stable populations. Gynogenesis is a form of obligate parthenogenesis where

10624-495: The formation and fusion of gametes, mechanisms for lateral gene transfer such as conjugation , transformation and transduction can be likened to sexual reproduction in the sense of genetic recombination in meiosis . Prokaryotes ( Archaea and Bacteria ) reproduce asexually through binary fission , in which the parent organism divides in two to produce two genetically identical daughter organisms. Eukaryotes (such as protists and unicellular fungi ) may reproduce in

10752-527: The individuals are clones, and the clonal population may cover a large area. Many multicellular organisms produce spores during their biological life cycle in a process called sporogenesis . Exceptions are animals and some protists, which undergo meiosis immediately followed by fertilization. Plants and many algae on the other hand undergo sporic meiosis where meiosis leads to the formation of haploid spores rather than gametes. These spores grow into multicellular individuals called gametophytes , without

10880-510: The institution became even more deeply an integral part of the South's economy. With the opening up of frontier lands after the government forced most Native Americans to move west of the Mississippi, there was a major migration of both whites and blacks to those territories. From the 1820s through the 1850s, more than one million enslaved Africans were transported to the Deep South in forced migration, two-thirds of them by slave traders and

11008-567: The invention of the cotton gin , short staple cotton could be grown more widely. This led to an explosion of cotton cultivation, especially in the frontier uplands of Georgia, Alabama and other parts of the Deep South, as well as riverfront areas of the Mississippi Delta. Migrants poured into those areas in the early decades of the 19th century, when county population figures rose and fell as swells of people kept moving west. The expansion of cotton cultivation required more slave labor, and

11136-520: The labor-intensive cultivation of tobacco, the first cash crop of Virginia. Tobacco exhausted the soil quickly, requiring that farmers regularly clear new fields. They used old fields as pasture, and for crops such as corn wheat, or allowed them to grow into woodlots. The Barbados Slave Code served as the basis for the slave codes adopted in the British American colonies, including Carolina , Georgia , and Antigua . In other colonies where

11264-574: The land in return for their financial and political assistance in restoring him to the throne in 1660. The granted lands included all or part of the present-day U.S. states of North Carolina, Tennessee, South Carolina, Georgia, Alabama, Mississippi, and Florida. In the British colonies, immigration began in 1607 and continued until the outbreak of the Revolution in 1775. Settlers cleared land, built houses and outbuildings, and on their own farms. The Southern rich owned large plantations that dominated export agriculture and used slaves. Many were involved in

11392-504: The land to farm for a while. Some freedpeople left the South altogether for states such as Ohio and Indiana, and later, Kansas. Thousands of others joined the migration to new opportunities in the Mississippi and Arkansas Delta bottomlands, and Texas. With passage of the 13th Amendment to the Constitution of the United States (which outlawed slavery), the 14th Amendment (which granted full U.S. citizenship to African Americans) and

11520-512: The little fire ant Wasmannia auropunctata , Vollenhovia emeryi , Paratrechina longicornis , occasionally in Apis mellifera , the Hypseleotris carp gudgeons, the parasitoid Venturia canescens , and occasionally in fruit flies Drosophila melanogaster carrying a specific mutant allele. It has also been induced in many crops and fish via irradiation of an egg cell to destroy

11648-404: The little fire ant Wasmannia auropunctata , Vollenhovia emeryi , Paratrechina longicornis , occasionally in Apis mellifera , the Hypseleotris carp gudgeons, the parasitoid Venturia canescens , and occasionally in fruit flies Drosophila melanogaster carrying a specific mutant allele. It has also been induced in many crops and fish via irradiation of an egg cell to destroy

11776-412: The maternal nuclear genome can be eliminated from the zygote, or the female can produce an egg with no nucleus , resulting in an embryo developing with only the genome of the male gamete. Other type of androgenesis is the male apomixis or paternal apomixis is a reproductive process in which a plant develops from a sperm cell (male gamete) without the participation of a female cell (ovum). In this process,

11904-415: The maternal nuclear genome. Obligate androgenesis is the process in which males are capable of producing both eggs and sperm, however, the eggs have no genetic contribution and the offspring come only from the sperm, which allows these individuals to self-fertilize and produce clonal offspring without the need for females. They are also capable of interbreeding with sexual and other androgenetic lineages in

12032-597: The maternal nuclear genome. Some species can alternate between sexual and asexual strategies, an ability known as heterogamy , depending on many conditions. Alternation is observed in several rotifer species (cyclical parthenogenesis e.g. in Brachionus species) and a few types of insects. One example of this is aphids which can engage in heterogony. In this system, females are born pregnant and produce only female offspring. This cycle allows them to reproduce very quickly. However, most species reproduce sexually once

12160-672: The mid-to-late-1870s, some upper class Southerners created increasing resistance to the altered social structure. Paramilitary organizations such as the White League in Louisiana (1874), the Red Shirts in Mississippi (1875) and rifle clubs, all "White Line" organizations, used organized violence against Republicans , both black and white, to remove Republicans from political office, repress and bar black voting, and restore

12288-428: The more common apomixis, where development occurs without fertilization, but with genetic material only from the mother. There are also clonal species that reproduce through vegetative reproduction like Lomatia tasmanica and Pando , where the genetic material is exclusively male. Other species where androgenesis has been observed naturally are the stick insects Bacillus rossius and Bassillus Grandii ,

12416-632: The number of immigrants arriving at Southern ports began to increase, although the North continued to receive the most immigrants. Huguenots were among the first settlers in Charleston, along with the largest number of Orthodox Jews outside of New York City. Numerous Irish immigrants settled in New Orleans, establishing a distinct ethnic enclave now known as the Irish Channel . Germans also went to New Orleans and its environs, resulting in

12544-762: The original Southern states was English . In the 17th century, most voluntary immigrants were of English origin and settled chiefly along the eastern coast but had pushed as far inland as the Appalachian Mountains by the 18th century. The majority of early English settlers were indentured servants , who gained freedom after working off their passage. The wealthier men, typically members of the English landed gentry , who paid their way received land grants known as headrights to encourage settlement. The Spanish and French established settlements in Florida , Texas , and Louisiana . The Spanish settled Florida in

12672-559: The others by masters who moved there. Planters in the Upper South sold slaves in excess of their needs as they shifted from tobacco to mixed agriculture. Many enslaved families were broken up, as planters preferred mostly strong males for field work. Two major political issues that festered in the first half of the 19th century caused political alignment along sectional lines, strengthened the identities of North and South as distinct regions with certain strongly opposed interests, and fed

12800-592: The parent or an exact clone of the parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria . Many eukaryotic organisms including plants , animals , and fungi can also reproduce asexually. In vertebrates , the most common form of asexual reproduction is parthenogenesis , which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited. Some monitor lizards , including Komodo dragons , can reproduce asexually. While all prokaryotes reproduce without

12928-557: The parent organism. Internal budding is a process of asexual reproduction, favoured by parasites such as Toxoplasma gondii . It involves an unusual process in which two ( endodyogeny ) or more ( endopolygeny ) daughter cells are produced inside a mother cell, which is then consumed by the offspring prior to their separation. Also, budding (external or internal) occurs in some worms like Taenia or Echinococcus ; these worms produce cysts and then produce (invaginated or evaginated) protoscolex with budding . Vegetative propagation

13056-503: The plant must usually be done by dividing existing colonies or growing rhizome cuttings. Conducting studies has been challenging; experimental plantings of cane in a study conducted by researchers at Mississippi State University to test the erosion mitigation potential of canebrakes yielded no results because only 1.2% of seedlings survived the following year. Southern Illinois University researchers have located 140 patches of giant cane and collaborate with many conservation organizations and

13184-468: The principles of the Revolution, along with Quaker and Methodist preachers who worked to encourage slaveholders to free their slaves. Planters such as George Washington often freed slaves by their wills. In the Upper South , more than 10% of all blacks were free by 1810, a significant expansion from pre-war proportions of less than 1% free. Cotton became dominant in the lower South after 1800. After

13312-463: The proportion of their populations that were African American slaves was much higher than in the Middle Colonies and New England Colonies , as shown on the map. According to Bertram Wyatt-Brown , "Bondage was an answer to an economic need. The South was not founded to create slavery; slavery was recruited to perpetuate the South." The Barbados Slave Code of 1661 served as the basis for

13440-572: The rebels fought on until Lee's army surrendered in April 1865. Once the Confederate forces surrendered, the region moved into the Reconstruction Era (1865–1877), in a partially successful attempt to rebuild the destroyed region and grant civil rights to freed slaves. Southerners who were against the Confederate cause during the Civil War were known as Southern Unionists . They were also known as Union Loyalists or Lincoln's Loyalists. Within

13568-624: The region have in recent decades come to favor Republicans , although both the Republican and Democratic Party are competitive in certain Southern swing states . The region contains almost all of the Bible Belt , an area of high Protestant church attendance, especially evangelical churches such as the Southern Baptist Convention . Historically, the South relied heavily on agriculture as its main economic base and

13696-446: The region were historically dominated by a small rural elite. The historical and cultural development of the South has been profoundly influenced by the institution of slave labor , especially in the Deep South and coastal plain areas, from the early 1600s to mid-1800s. This includes the presence of a large proportion of African Americans within the population, support for the doctrine of states' rights , and legacy of racism magnified by

13824-444: The regions dominant pre-war planter class . The South suffered more than the North overall, as the Union strategy of attrition warfare meant that Lee could not replace his casualties, and the total war waged by Sherman, Sheridan and other Union armies devastated the infrastructure and caused widespread poverty and distress. The Confederacy suffered military losses of 95,000 soldiers killed in action and 165,000 who died of disease, for

13952-429: The rest of the United States; however, this has declined since around the late 20th century, with many Southern areas becoming a melting pot of cultures and people. Ethnic groups in the South were the most diverse among American regions, and include strong European (especially English , Scots-Irish , Scottish , Irish , French , and Spanish ), African , and Native American ancestries. The politics and economy of

14080-446: The same cell membrane, sporogony results in sporozoites , and gametogony results in micro gametes . Some cells divide by budding (for example baker's yeast ), resulting in a "mother" and a "daughter" cell that is initially smaller than the parent. Budding is also known on a multicellular level; an animal example is the hydra , which reproduces by budding. The buds grow into fully matured individuals which eventually break away from

14208-548: The slave codes adopted in the British American colonies of the Province of Carolina and the Province of Georgia . In other colonies where the slaves codes were not an exact copy, such as the Colony of Virginia and the Province of Maryland , the influence of the Barbados Slave Code can be traced throughout various provisions. During the American Revolutionary War , the Southern colonies helped embrace

14336-740: The social pathway, they form a multi-cellular slug which then forms a fruiting body with asexually generated spores. In the sexual pathway, two cells fuse to form a giant cell that develops into a large cyst. When this macrocyst germinates, it releases hundreds of amoebic cells that are the product of meiotic recombination between the original two cells. The hyphae of the common mold ( Rhizopus ) are capable of producing both mitotic as well as meiotic spores. Many algae similarly switch between sexual and asexual reproduction. A number of plants use both sexual and asexual means to produce new plants, some species alter their primary modes of reproduction from sexual to asexual under varying environmental conditions. In

14464-513: The south United States occurs around 9500 BC with the appearance of the earliest documented Americans, who are now referred to as Paleo-Indians . Paleoindians were hunter-gatherers that roamed in bands and frequently hunted megafauna . Several cultural stages, such as Archaic ( c.  8000 –1000 BC) and the Woodland ( c.  1000 BC – AD 1000), preceded what the Europeans found at

14592-532: The southern pine forests , the warm temperate montane forest of the Appalachians, the savannas of the southern Great Plains, and the subtropical jungle and maritime forests along the Atlantic and Gulf coasts. Unique flora include various species of magnolia, rhododendron, cane, palm, and oak, among others. Fauna of the region is also diverse, encompassing a plethora of amphibian species, reptiles such as

14720-444: The state of Kentucky attempted to remain neutral, and it could only do so briefly. When Lincoln called for troops to suppress what he referred to as "combinations too powerful to be suppressed by the ordinary" judicial or martial means, four more states decided to secede and join the Confederacy (which then moved its capital to Richmond, Virginia). Although the Confederacy had large supplies of captured munitions and many volunteers, it

14848-519: The structural features and prey base that the species seeks. Contrary to the characterization of canebrakes as homogenous, they host a great diversity of species, including globally rare species. A survey of canebrakes in the Carolinas found 330 taxa living in the canebrake habitat, a number that would likely increase with more study. Canebrakes provide habitat for the critically endangered Alabama canebrake pitcher plant ( Sarracenia alabamensis) , which

14976-462: The traditional low-tariff policy of the South by imposing a new 15% tax on all imports from the Union. The Union blockade stopped most commerce from entering the South, and smugglers avoided the tax, so the Confederate tariff produced too little revenue to finance the war. Inflated currency was the solution, but that created distrust of the Richmond government. Because of low investment in railroads,

15104-540: The underground rhizomes unharmed. Canebrakes have been identified as important ecosystems for supporting over 70 wildlife species, possibly ideal candidates for mitigating nitrate pollution in groundwater, and crucial to the material cultures of Southeastern Native American nations, but relatively little study has been devoted to them, partially because virtually all canebrakes that still exist are isolated and fragmentary. Canebrakes are unlikely to be reestablished significantly under current methods of land management, but there

15232-494: The zygote is formed solely with genetic material from the father, resulting in offspring genetically identical to the male organism. This has been noted in many plants like Nicotiana , Capsicum frutescens , Cicer arietinum , Poa arachnifera , Solanum verrucosum , Phaeophyceae , Pripsacum dactyloides , Zea mays , and occurs as the regular reproductive method in Cupressus dupreziana . This contrasts with

15360-402: Was a cosmopolitan port with a variety of jobs that attracted more immigrants than other areas of the South. Because of lack of investment, however, construction of railroads to span the region lagged behind the North. People relied most heavily on river traffic for getting their crops to market and for transportation. Between 1830 and 1850, Native Americans were removed from their home states in

15488-514: Was difficult as people grappled with the effects of a new labor economy of a free market in the midst of a widespread agricultural depression. In addition, the limited infrastructure the South had was mostly destroyed by the war. At the same time, the North was rapidly industrializing. To avoid the social effects of the war, most of the Southern states initially passed black codes . During Reconstruction, these were mostly legally nullified by federal law and anti-Confederate legislatures, which existed for

15616-412: Was elected the first Republican president in 1860, seven cotton states declared their secession and formed the Confederate States of America before Lincoln was inaugurated. The United States government, both outgoing and incoming, refused to recognize the Confederacy, and when the new Confederate President Jefferson Davis ordered his troops to open fire on Fort Sumter in April 1861, war broke out. Only

15744-469: Was initially finessed by political compromises designed to balance the number of "free" and "slave" states. The issue resurfaced in a more virulent form, however, around the time of the Mexican–American War , which raised the stakes by adding new territories primarily on the Southern side of the imaginary geographic divide. Congress opposed allowing slavery in these territories. Before the Civil War,

15872-470: Was predominantly rural until after World War II . Since the 1940s, the region has become more economically diversified and metropolitan , helping attract both national and international migrants. In the 21st century, it is the fastest-growing region in the United States, with Houston being the region's largest city. The South is a diverse meteorological region with numerous climatic zones, including temperate , sub-tropical , tropical , and arid —though

16000-516: Was slower than the Union in dealing with the border states. While the Upland South border states of Kentucky, Missouri, West Virginia, Maryland, and Delaware, as well as the District of Columbia , continued to permit slavery during the Civil War, they remained with the Union though Kentucky and Missouri both had rival Confederate governments that formed that were admitted and recognized by

16128-414: Was the wealthiest city in the country and the third largest in population. The success of the city was based on the growth of international trade associated with products being shipped to and from the interior of the country down the Mississippi River. New Orleans also had the largest slave market in the country, as traders brought slaves by ship and overland to sell to planters across the Deep South. The city

16256-478: Was thought that the ZW chromosome system used by reptiles was incapable of producing viable WW offspring, but a (ZW) female boa constrictor was discovered to have produced viable female offspring with WW chromosomes. The female boa could have chosen any number of male partners (and had successfully in the past) but on this occasion she reproduced asexually, creating 22 female babies with WW sex-chromosomes. Polyembryony

16384-440: Was to travel through. For example, in 1728 William Byrd described hacking through a "forest" of cane "more than a furlong [220 yards] in depth" as he blazed a trail along the border of Virginia and Carolina. Likewise, William Bartram described "the most extensive Canebreak that is to be seen on the face of the whole earth," writing that the canes grew 10-12 feet tall and so close together they were completely impassable without hacking
