A zoo (short for zoological garden ; also called an animal park or menagerie ) is a facility in which animals are kept within enclosures for public exhibition and often bred for conservation purposes.
130-660: The Madrid Zoo Aquarium is a 20-hectare (49-acre) zoo and aquarium located in the Casa de Campo in Madrid , Spain. The zoo is owned by the city, but is managed by the international entertainment operator Parques Reunidos . Opened in 1770, it is one of the largest zoos in Spain and one of the few zoos in the world that houses giant pandas . The zoo is a member of the European Association of Zoos and Aquaria (EAZA) and
260-537: A bear and a bull , chained together, rolled in fierce combat across the sand ... Four hundred bears were killed in a single day under Caligula ... Under Nero , four hundred tigers fought with bulls and elephants. In a single day, at the dedication of the Colosseum by Titus , five thousand animals perished. Under Trajan ... lions , tigers, elephants, rhinoceroses , hippopotami, giraffes, bulls, stags, even crocodiles and serpents were employed to give novelty to
390-467: A petting zoo , an aquarium with 2,000,000 L (530,000 US gal) of salt water, a dolphin exhibit , and an aviary . Facilities include several restaurants, a boat tour, and train tour. It is home to over 6,000 animals of 500 different species. In 1978, China presented the King of Spain with two giant pandas , Shao Shao and Quian Quiang. Their cub, Chu-lin, born in 1982, died in 1996. Chu-lin
520-499: A species binomial (estimated range: 1.5–8 million). Less than 1% of all species that have been described beyond simply noting its existence. From these figures, the IUCN reports that 23% of vertebrates , 5% of invertebrates and 70% of plants that have been evaluated are designated as endangered or threatened . Better knowledge is being constructed by The Plant List for actual numbers of species. Systematic conservation planning
650-810: A wildlife sanctuary was founded on the Farne Islands by St Cuthbert in response to his religious beliefs. Natural history was a major preoccupation in the 18th century, with grand expeditions and the opening of popular public displays in Europe and North America . By 1900 there were 150 natural history museums in Germany , 250 in Great Britain , 250 in the United States , and 300 in France . Preservationist or conservationist sentiments are
780-518: A "house of animals" with a large collection of birds, mammals and reptiles in a garden tended by more than 600 employees. The garden was described by several Spanish conquerors, including Hernán Cortés in 1520. After the Aztec revolt against the Spanish rule, and during the subsequent battle for the city, Cortés reluctantly ordered the zoo to be destroyed. The oldest zoo in the world still in existence
910-400: A Congolese pygmy , displayed in a cage with the chimpanzees, then with an orangutan named Dohong, and a parrot. The exhibit was intended as an example of the "missing link" between the orangutan and white man. It triggered protests from the city's clergymen, but the public reportedly flocked to see Benga. Humans were also displayed at various events, especially colonial expositions such as
1040-482: A consequence, various management tools are used to preserve the space for the genetically most important individuals and to reduce the risk of inbreeding . Management of animal populations is typically through international organizations such as AZA and EAZA . Zoos have several different ways of managing the animal populations, such as moves between zoos, contraception , sale of excess animals and euthanization (culling). Contraception can be an effective way to limit
1170-510: A conservation project, it is important to understand how an ecosystem functions and what role different species and abiotic factors have within the system. It is important to have a precise reason for why ecological monitoring is implemented; within the context of conservation, this reasoning is often to track changes before, during, or after conservation measures are put in place to help a species or habitat recover from degradation and/or maintain integrity. Another benefit of ecological monitoring
1300-417: A development of the late 18th to early 20th centuries. Before Charles Darwin set sail on HMS Beagle , most people in the world, including Darwin, believed in special creation and that all species were unchanged. George-Louis Leclerc was one of the first naturalist that questioned this belief. He proposed in his 44 volume natural history book that species evolve due to environmental influences. Erasmus Darwin
1430-610: A difference in wildlife conservation and education. Humans were occasionally displayed in cages at zoos along with non-human animals, to illustrate the differences between people of European and non-European origin. In September 1906, William Hornaday , director of the Bronx Zoo in New York—;with the agreement of Madison Grant , head of the New York Zoological Society —had Ota Benga ,

#17327660765741560-518: A faster rate than other species. Amphibians spend parts of their time in the water and on land, making them susceptible to changes in both environments. They also have very permeable skin that allows them to breath and intake water, which means they also take any air or water-soluble pollutants in as well. Birds often cover a wide range in habitat types annually, and also generally revisit the same nesting site each year. This makes it easier for researchers to track ecological effects at both an individual and
1690-676: A gas station. The animals may be trained to perform tricks, and visitors are able to get closer to them than in larger zoos. Since they are sometimes less regulated, roadside zoos are often subject to accusations of neglect and cruelty . In June 2014 the Animal Legal Defense Fund filed a lawsuit against the Iowa-based roadside Cricket Hollow Zoo for violating the Endangered Species Act by failing to provide proper care for its animals. Since filing
1820-458: A greenhouse with an aviary, aquarium, and museum of stuffed animals and birds), a pond, a bridge over a waterfall, an artificial lake with a fountain, a wood-ornamented greenhouse, a forest area, and enclosures and buildings. The first zoological garden in Australia was Melbourne Zoo in 1860. In German states leading roles came Berlin (1841), Frankfurt (1856), and Hamburg (1863). In 1907,
1950-399: A history that extends prior to the age of conservation. Resource ethics grew out of necessity through direct relations with nature. Regulation or communal restraint became necessary to prevent selfish motives from taking more than could be locally sustained, therefore compromising the long-term supply for the rest of the community. This social dilemma with respect to natural resource management
2080-509: A lack of natural wild habitat in which to reintroduce animals. This highlights the importance of in situ conservation, or preservation of natural spaces, in addition to the utility of zoo captive breeding and reintroduction programs. In situ conservation and reintroduction programs are key elements to obtaining certification by reputable organisations such as the Association of Zoos and Aquariums (AZA). Efforts to clone endangered species in
2210-435: A large collection of primates, including western lowland gorillas , chimpanzees , mandrills , mantled guerezas , orangutans and several species of lemurs . The dolphinarium at Zoo Aquarium was built in 1987 and currently has nine bottlenose dolphins : Lala (F), Einyel (F), Guarina (F), Mary (F), Mancha (F), Loren (M), Noa (F), Iruka (F) and Coral (F). Zoo The term zoological garden refers to zoology ,
2340-461: A matter of public interest in the 1970s, a few zoos began to consider making conservation their central role, with Gerald Durrell of the Jersey Zoo , George Rabb of Brookfield Zoo , and William Conway of the Bronx Zoo ( Wildlife Conservation Society ) leading the discussion. From then on, zoo professionals became increasingly aware of the need to engage themselves in conservation programs, and
2470-448: A model of cooperation for conservation. Loaned animals usually remain the property of the original park, and any offspring yielded by loaned animals are usually divided between the lending and holding institutions. For decades the capture of wild animals or purchasing of animals has been broadly considered unethical and has not been practiced by reputable zoos. Especially in large animals, a limited number of spaces are available in zoos. As
2600-517: A multitude of other variables such as loss of biodiversity as a function of the rate of habitat loss and site occupancy to obtain such estimates. The Theory of Island Biogeography is possibly the most significant contribution toward the scientific understanding of both the process and how to measure the rate of species extinction. The current background extinction rate is estimated to be one species every few years. Actual extinction rates are estimated to be orders of magnitudes higher. While this
2730-628: A new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with a group of leading university and zoo researchers and conservationists including Kurt Benirschke , Sir Otto Frankel , Thomas Lovejoy , and Jared Diamond . The meeting
SECTION 20
#17327660765742860-418: A new strategy that sets out the aims and mission of zoological gardens of the 21st century. When studying behaviour of captive animals, several things should however be taken into account before drawing conclusions about wild populations. Including that captive populations are often smaller than wild ones and that the space available to each animal is often less than in the wild. Conservation programs all over
2990-434: A place of refuge . Today, many zoos are improving enclosures by including tactile and sensory features in the habitat that allow animals to encourage natural behaviors. These additions can prove to be effective in improving the lives of animals in captivity. The tactile and sensory features will vary depending on the species of animal. There are animals that are injured in the wild and are unable to survive on their own, but in
3120-458: A population level for the species. Many conservation researchers believe that having a long-term ecological monitoring program should be a priority for conservation projects, protected areas, and regions where environmental harm mitigation is used. Conservation biologists are interdisciplinary researchers that practice ethics in the biological and social sciences. Chan states that conservationists must advocate for biodiversity and can do so in
3250-481: A population's breeding. However it may also have health repercussions and can be difficult or even impossible to reverse in some animals. Additionally, some species may lose their reproductive capability entirely if prevented from breeding for a period (whether through contraceptives or isolation), but further study is needed on the subject. Sale of surplus animals from zoos was once common and in some cases animals have ended up in substandard facilities. In recent decades
3380-415: A protected existence that halts interference from the humans. In this regard, conservationists differ from preservationists in the social dimension, as conservation biology engages society and seeks equitable solutions for both society and ecosystems. Some preservationists emphasize the potential of biodiversity in a world without humans. Ecological monitoring is the systematic collection of data relevant to
3510-601: A small number of zoos. To solve this organizations like EAZA and AZA have begun to develop husbandry manuals. Many modern zoos attempt to improve animal welfare by providing more space and behavioural enrichments . This often involves housing the animals in naturalistic enclosures that allow the animals to express more of their natural behaviours, such as roaming and foraging. Whilst many zoos have been working hard on this change, in some zoos, some enclosures still remain barren concrete enclosures or other minimally enriched cages. Animal conservation Conservation biology
3640-547: A suitable alternative. Off-site conservation relies on zoos, national parks, or other care facilities to support the rehabilitation of the animals and their populations. Zoos benefit conservation by providing suitable habitats and care to endangered animals. When properly regulated, they present a safe, clean environment for the animals to increase populations sizes. A study on amphibian conservation and zoos addressed these problems by writing, Whilst addressing in situ threats, particularly habitat loss, degradation and fragmentation,
3770-553: A suitable environment for wild native animals such as herons to live in or visit. A colony of black-crowned night herons has regularly summered at the National Zoo in Washington, D.C. for more than a century. Some zoos may provide information to visitors on wild animals visiting or living in the zoo, or encourage them by directing them to specific feeding or breeding platforms. In modern, well-regulated zoos, breeding
3900-470: A whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering. Extinction rates are measured in a variety of ways. Conservation biologists measure and apply statistical measures of fossil records , rates of habitat loss , and
4030-589: A year and have special programs for schools. They are organized by the Association of Zoos and Aquariums . Japan's first modern zoo, Tokyo's Ueno Imperial Zoological Gardens , opened in 1882 based on European models. In World War II it was used to teach the Japanese people about the lands recently conquered by the Army. In 1943, fearing American bombing attacks, the government ordered the zoo to euthanize dangerous animals that might escape. When ecology emerged as

It maintains two research institutes, the Nuffield Institute of Comparative Medicine and the Wellcome Institute of Comparative Physiology. In the United States, the Penrose Research Laboratory of the Philadelphia Zoo focuses on the study of comparative pathology . The World Association of Zoos and Aquariums produced its first conservation strategy in 1993, and in November 2004, it adopted
4290-537: Is an effective way to seek and identify efficient and effective types of reserve design to capture or sustain the highest priority biodiversity values and to work with communities in support of local ecosystems. Margules and Pressey identify six interlinked stages in the systematic planning approach: Conservation biologists regularly prepare detailed conservation plans for grant proposals or to effectively coordinate their plan of action and to identify best management practices (e.g. ). Systematic strategies generally employ
4420-492: Is an interdisciplinary network with professional alliances in the biological as well as social sciences. Those dedicated to the cause and profession advocate for a global response to the current biodiversity crisis based on morals , ethics , and scientific reason. Organizations and citizens are responding to the biodiversity crisis through conservation action plans that direct research, monitoring, and education programs that engage concerns at local through global scales. There
4550-490: Is based on a new philosophy or leadership theory steering away from historical notions of power, authority, and dominance. Adaptive conservation leadership is reflective and more equitable as it applies to any member of society who can mobilize others toward meaningful change using communication techniques that are inspiring, purposeful, and collegial. Adaptive conservation leadership and mentoring programs are being implemented by conservation biologists through organizations such as
4680-414: Is controlled to maintain a self-sustaining, global captive population. This is not the case in some less well-regulated zoos, often based in poorer regions. Overall "stock turnover" of animals during a year in a select group of poor zoos was reported as 20%-25% with 75% of wild caught apes dying in captivity within the first 20 months. The authors of the report stated that before successful breeding programs,
4810-423: Is debate on which metrics that money, time and personnel should be dedicated to for the best chance of making a positive impact. One specific general discussion topic is whether monitoring should happen where there is little human impact (to understand a system that has not been degraded by humans), where there is human impact (so the effects from humans can be investigated), or where there is data deserts and little
4940-602: Is important, it's worth noting that there are no models in existence that account for the complexity of unpredictable factors like species movement, a non-analog climate, changing species interactions, evolutionary rates on finer time scales, and many other stochastic variables. The measure of ongoing species loss is made more complex by the fact that most of the Earth's species have not been described or evaluated. Estimates vary greatly on how many species actually exist (estimated range: 3,600,000–111,700,000) to how many have received
5070-407: Is increasing recognition that conservation is not just about what is achieved but how it is done. The conservation of natural resources is the fundamental problem. Unless we solve that problem, it will avail us little to solve all others. – Theodore Roosevelt Conscious efforts to conserve and protect global biodiversity are a recent phenomenon. Natural resource conservation, however, has
5200-436: Is known about the habitats' and communities' response to human perturbations . The concept of bioindicators / indicator species can be applied to ecological monitoring as a way to investigate how pollution is affecting an ecosystem. Species like amphibians and birds are highly susceptible to pollutants in their environment due to their behaviours and physiological features that cause them to absorb pollutants at
5330-569: Is now directed at urban conservation biology. The Society for Conservation Biology originated in 1985. By 1992, most of the countries of the world had become committed to the principles of conservation of biological diversity with the Convention on Biological Diversity ; subsequently many countries began programmes of Biodiversity Action Plans to identify and conserve threatened species within their borders, as well as protect associated habitats. The late 1990s saw increasing professionalism in

5460-462: Is of primary importance; for many amphibian species in situ conservation alone will not be enough, especially in light of current un-mitigatable threats that can impact populations very rapidly such as chytridiomycosis [an infectious fungal disease]. Ex situ programmes can complement in situ activities in a number of ways including maintaining genetically and demographically viable populations while threats are either better understood or mitigated in
5590-977: Is often called the " Tragedy of the Commons ". From this principle, conservation biologists can trace communal resource based ethics throughout cultures as a solution to communal resource conflict. For example, the Alaskan Tlingit peoples and the Haida of the Pacific Northwest had resource boundaries, rules, and restrictions among clans with respect to the fishing of sockeye salmon . These rules were guided by clan elders who knew lifelong details of each river and stream they managed. There are numerous examples in history where cultures have followed rules, rituals, and organized practice with respect to communal natural resource management. The Mauryan emperor Ashoka around 250 BC issued edicts restricting
5720-660: Is particularly relevant to practitioners in that it has the potential to generate cause-and-effect relationships and reveal the factors that contribute to population declines. The Society for Conservation Biology is a global community of conservation professionals dedicated to advancing the science and practice of conserving biodiversity. Conservation biology as a discipline reaches beyond biology, into subjects such as philosophy , law , economics , humanities , arts , anthropology , and education . Within biology, conservation genetics and evolution are immense fields unto themselves, but these disciplines are of prime importance to

There is a movement in conservation biology suggesting a new form of leadership is needed to mobilize conservation biology into a more effective discipline that is able to communicate the full scope of the problem to society at large. The movement proposes an adaptive leadership approach that parallels an adaptive management approach. The concept

It was constructed by Adrian van Stekhoven in 1752 at the order of Emperor Francis I , to serve as an imperial menagerie as part of Schönbrunn Palace . The menagerie was initially reserved for the viewing pleasure of the imperial family and the court, but was made accessible to the public in 1765. In 1775, a zoo was founded in Madrid, and in 1795,

The oldest known zoological collection was revealed during excavations at Hierakonpolis , Egypt in 2009, of a c. 3500 BCE menagerie. The exotic animals included hippopotami , hartebeest , elephants , baboons and wildcats . King Ashur-bel-kala of the Middle Assyrian Empire created zoological and botanical gardens in

Not only is ecological monitoring data important for convincing politicians, funders, and the public why a conservation program is important to implement, but also to keep them convinced that a program should be continued to be supported. There is plenty of debate on how conservation resources can be used most efficiently; even within ecological monitoring, there

Housing over 10 thousand animals, the facility's breadth extends from housing insects such cockroaches to large mammals like elephants on an area of over 33 hectares . In the United States, the Philadelphia Zoo , opened on July 1, 1874, earning its motto "America's First Zoo." The Lincoln Park Zoological Gardens in Chicago and
6630-541: The American Zoo Association soon said that conservation was its highest priority. In order to stress conservation issues, many large zoos stopped the practice of having animals perform tricks for visitors. The Detroit Zoo , for example, stopped its elephant show in 1969, and its chimpanzee show in 1983, acknowledging that the trainers had probably abused the animals to get them to perform. Mass destruction of wildlife habitat has yet to cease all over

The 500-acre (2.0 km ) Werribee Open Range Zoo in Melbourne, Australia, displays animals living in an artificial savannah . The first public aquarium
7020-480: The ecology of a species or habitat at repeating intervals with defined methods. Long-term monitoring for environmental and ecological metrics is an important part of any successful conservation initiative. Unfortunately, long-term data for many species and habitats is not available in many cases. A lack of historical data on species populations , habitats, and ecosystems means that any current or future conservation work will have to make assumptions to determine if

Conservation may be classified as either in-situ conservation , which is protecting an endangered species in its natural habitat , or ex-situ conservation , which occurs outside the natural habitat. In-situ conservation involves protecting or restoring the habitat. Ex-situ conservation, on the other hand, involves protection outside of an organism's natural habitat, such as on reservations or in gene banks , in circumstances where viable populations may not be present in
7930-552: The Cincinnati Zoo opened in 1875. In the 1930s, federal relief programs provided financial aid to most local zoos. The Works Progress Administration and similar New Deal government agencies helped greatly in the construction, renovation, and expansion of zoos when the Great Depression severely reduced local budgets.

The programme was adopted by the General Conference of UNESCO in 1972. As of 2006, a total of 830 sites are listed: 644 cultural, 162 natural. The first country to pursue aggressive biological conservation through national legislation was the United States, which passed back to back legislation in
8580-550: The United States, Europe, and Asia are frequently embedded in zoos and zoological parks. The position of most modern zoos in Australasia , Asia , Europe , and North America , particularly those with scientific societies, is that they display wild animals primarily for the conservation of endangered species , as well as for research purposes and education, and secondarily for the entertainment of visitors. The Zoological Society of London states in its charter that its aim

The term "zoological park" was used for more expansive facilities in Halifax, Nova Scotia , Washington, D.C. , and the Bronx in New York, which opened in 1846, 1891 and 1899 respectively. Relatively new terms for zoos in the late 20th century are " conservation park" or "bio park". Adopting a new name is a strategy used by some zoo professionals to distance their institutions from
8840-737: The animals and visitors. Nocturnal animals are often housed in buildings with a reversed light-dark cycle, i.e. only dim white or red lights are on during the day so the animals are active during visitor hours, and brighter lights on at night when the animals sleep. Special climate conditions may be created for animals living in extreme environments, such as penguins. Special enclosures for birds , mammals , insects , reptiles , fish , and other aquatic life forms have also been developed. Some zoos have walk-through exhibits where visitors enter enclosures of non-aggressive species, such as lemurs , marmosets , birds, lizards , and turtles . Visitors are asked to keep to paths and avoid showing or eating foods that
8970-493: The animals might snatch. Some zoos keep animals in larger, outdoor enclosures, confining them with moats and fences, rather than in cages. Safari parks , also known as zoo parks and lion farms, allow visitors to drive through them and come in close proximity to the animals. Sometimes, visitors are able to feed animals through the car windows. The first safari park was Whipsnade Park in Bedfordshire, England, opened by

During the 18th century, the price of admission was three half-pence, or the supply of a cat or dog for feeding to the lions. The animals were moved to the London Zoo when it opened. Aztec emperor Moctezuma had in his capital city of Tenochtitlan
9230-434: The animals' needs, but constraints such as size and expense can complicate this. The type of enclosure and the husbandry are of great importance in determining the welfare of animals. Substandard enclosures can lead to decreased lifespans, caused by factors as human diseases, unsafe materials in the cages and possible escape attempts (Bendow 382). However, when zoos take time to think about the animal's welfare, zoos can become
9360-467: The area covered due to unplanned urbanization activities. Then they plant the new saplings of same tree families of that existing forest in the areas where the old forest has been lost and also plant those saplings to the barren areas connected to the forest. This maintains the density and area covered by the forest. Also, non-interference may be used, which is termed a preservationist method. Preservationists advocate for giving areas of nature and species

Some examples are Busch Gardens Tampa Bay in Tampa, Florida , both Disney's Animal Kingdom and Gatorland in Orlando, Florida , Flamingo Land in North Yorkshire, England , and Six Flags Discovery Kingdom in Vallejo, California . By 2000 most animals being displayed in zoos were the offspring of other zoo animals. This trend, however
9880-525: The culling proceeded. Although zoos in some countries have been open about culling, the controversy of the subject and pressure from the public has resulted in others being closed. This stands in contrast to most zoos publicly announcing animal births. Furthermore, while many zoos are willing to cull smaller and/or low-profile animals, fewer are willing to do it with larger high-profile species. Many animals breed readily in captivity. Zoos frequently are forced to intentionally limit captive breeding because of
10010-512: The different organizing principle of geography, as opposed to taxonomy. The Wrocław Zoo ( Polish : Ogród Zoologiczny we Wrocławiu ) is the oldest zoo in Poland, opened in 1865 when the city was part of Prussia , and was home to about 10,500 animals representing about 1,132 species (in terms of the number of animal species, it is the third largest in the world ). In 2014 the Wrocław Zoo opened
10140-662: The early 19th century biogeography was ignited through the efforts of Alexander von Humboldt , Charles Lyell and Charles Darwin . The 19th-century fascination with natural history engendered a fervor to be the first to collect rare specimens with the goal of doing so before they became extinct by other such collectors. Although the work of many 18th and 19th century naturalists were to inspire nature enthusiasts and conservation organizations , their writings, by modern standards, showed insensitivity towards conservation as they would kill hundreds of specimens for their collections. The modern roots of conservation biology can be found in
10270-620: The emergence of the urban conservation movement. A local organization was established in Birmingham , UK, a development followed in rapid succession in cities across the UK, then overseas. Although perceived as a grassroots movement , its early development was driven by academic research into urban wildlife. Initially perceived as radical, the movement's view of conservation being inextricably linked with other human activity has now become mainstream in conservation thought. Considerable research effort
10400-568: The enclosures and come into close proximity with the animals. The Zoological Society of London was founded in 1826 by Stamford Raffles and established the London Zoo in Regent's Park two years later in 1828. At its founding, it was the world's first scientific zoo. Originally intended to be used as a collection for scientific study , it was opened to the public in 1847. The Zoo was located in Regent's Park —then undergoing development at
10530-537: The entrepreneur Carl Hagenbeck founded the Tierpark Hagenbeck in Stellingen, now a quarter of Hamburg . His zoo was a radical departure from the layout of the zoo that had been established in 1828. It was the first zoo to use open enclosures surrounded by moats, rather than barred cages, to better approximate animals' natural environments. He also set up mixed-species exhibits and based the layout on
10660-746: The first conservation societies was the Royal Society for the Protection of Birds , founded in 1889 in Manchester as a protest group campaigning against the use of great crested grebe and kittiwake skins and feathers in fur clothing . Originally known as "the Plumage League", the group gained popularity and eventually amalgamated with the Fur and Feather League in Croydon, and formed
10790-458: The food is supplied by the zoo, either from vending machines or a kiosk nearby. An animal theme park is a combination of an amusement park and a zoo, mainly for entertaining and commercial purposes. Marine mammal parks such as Sea World and Marineland are more elaborate dolphinariums keeping whales , and containing additional entertainment attractions. Another kind of animal theme park contains more entertainment and amusement elements than
10920-410: The hands of the architect John Nash . What set the London zoo apart from its predecessors was its focus on society at large. The zoo was established in the middle of a city for the public, and its layout was designed to cater for the large London population. The London zoo was widely copied as the archetype of the public city zoo. In 1853, the Zoo opened the world's first public aquarium . Dublin Zoo
11050-410: The high mortality rate was the reason for the "massive scale of importations." One 2-year study indicated that of 19,361 mammals that left accredited zoos in the U.S. between 1992 and 1998, 7,420 (38%) went to dealers, auctions, hunting ranches, unaccredited zoos and individuals, and game farms. The welfare of zoo animals varies widely. Many zoos work to improve their animal enclosures and make it fit
11180-424: The importance of animal conservation, often through letting visitors witness the animals firsthand. Some critics, and the majority of animal rights activists, say that zoos, no matter their intentions, or how noble these intentions, are immoral and serve as nothing but to fulfill human leisure at the expense of the animals (an opinion that has spread over the years). However, zoo advocates argue that their efforts make
11310-482: The institutionalization of forest conservation activities in British India through the establishment of Forest Departments . The Madras Board of Revenue started local conservation efforts in 1842, headed by Alexander Gibson , a professional botanist who systematically adopted a forest conservation program based on scientific principles. This was the first case of state conservation management of forests in
11440-559: The late 18th-century Enlightenment period particularly in England and Scotland . Thinkers including Lord Monboddo described the importance of "preserving nature"; much of this early emphasis had its origins in Christian theology . Scientific conservation principles were first practically applied to the forests of British India . The conservation ethic that began to evolve included three core principles: that human activity damaged
11570-520: The lawsuit, ALDF has obtained records from investigations conducted by the USDA's Animal and Plant Health Inspection Services; these records show that the zoo is also violating the Animal Welfare Act. A petting zoo, also called petting farms or children's zoos, features a combination of domestic animals and wild species that are docile enough to touch and feed. To ensure the animals' health,
11700-479: The maintenance, loss, and restoration of biodiversity and the science of sustaining evolutionary processes that engender genetic , population , species , and ecosystem diversity. The concern stems from estimates suggesting that up to 50% of all species on the planet will disappear within the next 50 years, which will increase poverty and starvation, and will reset the course of evolution on this planet. Researchers acknowledge that projections are difficult, given
11830-457: The management, mainly for economic reasons, of such natural resources as timber , fish, game, topsoil , pastureland , and minerals. In addition it referred to the preservation of forests ( forestry ), wildlife ( wildlife refuge ), parkland, wilderness , and watersheds . This period also saw the passage of the first conservation legislation and the establishment of the first nature conservation societies. The Sea Birds Preservation Act of 1869
11960-423: The metric must be able to capture the trend of the population or habitat as a whole. Long-term monitoring can include the continued measuring of many biological, ecological, and environmental metrics including annual breeding success, population size estimates, water quality, biodiversity (which can be measured in many way, i.e. Shannon Index ), and many other methods. When determining which metrics to monitor for
12090-620: The mid-20th century, efforts arose to target individual species for conservation, notably efforts in big cat conservation in South America led by the New York Zoological Society. In the early 20th century the New York Zoological Society was instrumental in developing concepts of establishing preserves for particular species and conducting the necessary conservation studies to determine the suitability of locations that are most appropriate as conservation priorities;
12220-456: The modern era of conservation science and policy . The inherent multidisciplinary basis for conservation biology has led to new subdisciplines including conservation social science, conservation behavior and conservation physiology. It stimulated further development of conservation genetics which Otto Frankel had originated first but is now often considered a subdiscipline as well. The rapid decline of established biological systems around
12350-588: The movement toward wildlife conservation . In the 21st century professional conservation officers have begun to collaborate with indigenous communities for protecting wildlife in Canada. Some conservation efforts are yet to fully take hold due to ecological neglect. For example in the USA, 21st century bowfishing of native fishes, which amounts to killing wild animals for recreation and disposing of them immediately afterwards, remains unregulated and unmanaged. In
12480-460: The natural habitat. The conservation of habitats like forest, water or soil in its natural state is crucial for any species depending in it to thrive. Instead of making the whole new environment looking alike the original habitat of wild animals is less effective than preserving the original habitats. An approach in Nepal named reforestation campaign has helped increase the density and area covered by
12610-418: The original forests which proved to be better than creating entirely new environment after original one is let to lost. Old Forests Store More Carbon than Young Ones as proved by latest researches, so it is more crucial to protect the old ones. The reforestation campaign launched by Himalayan Adventure Therapy in Nepal basically visits the old forests in periodic basis which are vulnerable to loss of density and
12740-445: The practice and profession of conservation biology. Conservationists introduce bias when they support policies using qualitative description, such as habitat degradation , or healthy ecosystems . Conservation biologists advocate for reasoned and sensible management of natural resources and do so with a disclosed combination of science , reason , logic , and values in their conservation management plans. This sort of advocacy
12870-496: The practice of selling animals from certified zoos has declined. A large number of animals are culled each year in zoos, but this is controversial. A highly publicized culling as part of population management was that of a healthy giraffe at Copenhagen Zoo in 2014. The zoo argued that his genes already were well-represented in captivity, making the giraffe unsuitable for future breeding. There were offers to adopt him and an online petition to save him had many thousand signatories, but
13000-400: The rich, soft soil has been carried off and only the bare framework of the district left." In the bible, through Moses, God commanded to let the land rest from cultivation every seventh year. Before the 18th century, however, much of European culture considered it a pagan view to admire nature. Wilderness was denigrated while agricultural development was praised. However, as early as AD 680
13130-690: The sector, with the maturing of organisations such as the Institute of Ecology and Environmental Management and the Society for the Environment . Since 2000, the concept of landscape scale conservation has risen to prominence, with less emphasis being given to single-species or even single-habitat focused actions. Instead an ecosystem approach is advocated by most mainstream conservationists, although concerns have been expressed by those working to protect some high-profile species. Ecology has clarified
13260-546: The services of Geographic Information Systems to assist in the decision-making process. The SLOSS debate is often considered in planning. Conservation physiology was defined by Steven J. Cooke and colleagues as: An integrative scientific discipline applying physiological concepts, tools, and knowledge to characterizing biological diversity and its ecological implications; understanding and predicting how organisms, populations, and ecosystems respond to environmental change and stressors; and solving conservation problems across
13390-459: The slaughter of animals and certain kinds of birds, as well as opened veterinary clinics. Conservation ethics are also found in early religious and philosophical writings. There are examples in the Tao , Shinto , Hindu , Islamic and Buddhist traditions. In Greek philosophy, Plato lamented about pasture land degradation : "What is left now is, so to say, the skeleton of a body wasted by disease;
13520-654: The spectacle. Charlemagne had an elephant named Abul-Abbas that was given to him by the Abbasid caliph. King Henry I of England kept a collection of animals at his palace in Woodstock which reportedly included lions, leopards, and camels. The most prominent collection in medieval England was in the Tower of London , created as early as 1204 by King John I . Henry III received a wedding gift in 1235 of three leopards from Frederick II, Holy Roman Emperor , and in 1264,
13650-553: The stereotypical and nowadays criticized zoo concept of the 19th century. The term "bio park" was first coined and developed by the National Zoo in Washington D.C. in the late 1980s. In 1993, the New York Zoological Society changed its name to the Wildlife Conservation Society and re branded the zoos under its jurisdiction as "wildlife conservation parks". The predecessor of the zoological garden
13780-632: The study of animals. The term is derived from the Ancient Greek ζῷον , zōion , 'animal', and the suffix -λογία , -logia , 'study of'. The abbreviation zoo was first used of the London Zoological Gardens , which was opened for scientific study in 1828, and to the public in 1847. The first modern zoo was the Tierpark Hagenbeck by Carl Hagenbeck in Germany . In the United States alone, zoos are visited by over 181 million people annually. The London Zoo , which
13910-463: The tremendous expansion in the urbanization of London, led to a heightened demand for a greater variety of public forms of entertainment to be made available. The need for public entertainment, as well as the requirements of scholarly research, came together in the founding of the first modern zoos. Whipsnade Park Zoo in Bedfordshire , England, opened in 1931. It allowed visitors to drive through
14040-540: The unknown potential impacts of many variables, including species introduction to new biogeographical settings and a non-analog climate. Conservation biologists research and educate on the trends and process of biodiversity loss , species extinctions , and the negative effect these are having on our capabilities to sustain the well-being of human society. Conservation biologists work in the field and office, in government, universities, non-profit organizations and industry. The topics of their research are diverse, because this
14170-513: The wild The breeding of endangered species is coordinated by cooperative breeding programmes containing international studbooks and coordinators, who evaluate the roles of individual animals and institutions from a global or regional perspective, and there are regional programmes all over the world for the conservation of endangered species . In Africa, conservation is handled by the African Preservation Program (APP); in
14300-403: The work is having any effect on the population or ecosystem health. Ecological monitoring can provide early warning signals of deleterious effects (from human activities or natural changes in an environment) on an ecosystem and its species. In order for signs of negative trends in ecosystem or species health to be detected, monitoring methods must be carried out at appropriate time intervals, and
14430-466: The work of Henry Fairfield Osborn Jr., Carl E. Akeley , Archie Carr and his son Archie Carr III is notable in this era. Akeley for example, having led expeditions to the Virunga Mountains and observed the mountain gorilla in the wild, became convinced that the species and the area were conservation priorities. He was instrumental in persuading Albert I of Belgium to act in defense of
14560-420: The workings of the biosphere ; i.e., the complex interrelationships among humans, other species, and the physical environment. The burgeoning human population and associated agriculture , industry , and the ensuing pollution, have demonstrated how easily ecological relationships can be disrupted. The last word in ignorance is the man who says of an animal or plant: "What good is it?" If the land mechanism as
14690-403: The world and many species such as elephants , big cats, penguins , tropical birds, primates, rhinos , exotic reptiles, and many others are in danger of dying out. Many of today's zoos hope to stop or slow the decline of many endangered species and see their primary purpose as breeding endangered species in captivity and reintroducing them into the wild. Modern zoos also aim to help teach visitors
14820-516: The world fight to protect species from going extinct , but many conservation programs are underfunded and under-represented. Conservation programs can struggle to fight bigger issues like habitat loss and illness. It often takes significant funding and long time periods to rebuild degraded habitats, both of which are scarce in conservation efforts. The current state of conservation programs cannot rely solely in situ (on-site conservation) plans alone, ex situ (off-site conservation) may therefore provide
14950-419: The world means that conservation biology is often referred to as a "Discipline with a deadline". Conservation biology is tied closely to ecology in researching the population ecology ( dispersal , migration , demographics , effective population size , inbreeding depression , and minimum population viability ) of rare or endangered species . Conservation biology is concerned with phenomena that affect
15080-403: The world. Governor-General Lord Dalhousie introduced the first permanent and large-scale forest conservation program in the world in 1855, a model that soon spread to other colonies , as well the United States, where Yellowstone National Park was opened in 1872 as the world's first national park. The term conservation came into widespread use in the late 19th century and referred to
15210-556: The zoo inside the Jardin des Plantes in Paris was founded by Jacques-Henri Bernardin , with animals from the royal menagerie at Versailles, primarily for scientific research and education. The planning about a space for the conservation and observation of animals was expressed in connection with the political construction of republican citizenship. The Kazan Zoo , the first zoo in Russia
15340-432: The zoos they can live out the rest of their lives healthy and happy (McGaffin). In recent years, some zoos have chosen to move out some larger animals because they do not have the space available to provide an adequate enclosure for them (Lemonic, McDowell, and Bjerklie 50). An issue with animal welfare in zoos is that best animal husbandry practices are often not completely known, especially for species that are only kept in
15470-410: Was also a naturalist who also suggested that species evolved. Erasmus Darwin noted that some species have vestigial structures which are anatomical structures that have no apparent function in the species currently but would have been useful for the species' ancestors. The thinking of these early 18th century naturalists helped to change the mindset and thinking of the early 19th century naturalists. By
15600-571: Was and still is somewhat species-specific. When animals are transferred between zoos, they usually spend time in quarantine, and are given time to acclimatize to their new enclosures which are often designed to mimic their natural environment. For example, some species of penguins may require refrigerated enclosures. Guidelines on necessary care for such animals is published in the International Zoo Yearbook . Animal exchanges between facilities are usually made voluntarily, based on
15730-530: Was founded in 1806 by the Professor of Kazan State University Karl Fuchs . Until the early 19th century, the function of the zoo was often to symbolize royal power, like King Louis XIV 's menagerie at Versailles . Major cities in Europe set up zoos in the 19th century, usually using London and Paris as models. The transition was made from princely menageries designed to entertain high society with strange novelties into public zoological gardens. The new goal
15860-609: Was opened at the London Zoo in 1853. This was followed by the opening of public aquaria in continental Europe (e.g. Paris in 1859, Hamburg in 1864, Berlin in 1869, and Brighton in 1872) and the United States (e.g. Boston in 1859, Washington in 1873, San Francisco Woodward's Garden in 1873, and the New York Aquarium at Battery Park in 1896). Roadside zoos are found throughout North America , particularly in remote locations. They are often small, for-profit zoos, often intended to attract visitors to some other facility, such as
15990-531: Was opened in 1828, was initially known as the "Gardens and Menagerie of the Zoological Society of London", and it described itself as a menagerie or "zoological forest". The abbreviation "zoo" first appeared in print in the United Kingdom around 1847, when it was used for the Clifton Zoo , but it was not until some 20 years later that the shortened form became popular in the rhyming song " Walking in
16120-583: Was opened in 1831 by members of the medical profession interested in studying animals while they were alive and more particularly getting hold of them when they were dead. Downs' Zoological Gardens created by Andrew Downs and opened to the Nova Scotia public in 1847. It was originally intended to be used as a collection for scientific study. By the early 1860s, the zoo grounds covered 40 hectares with many fine flowers and ornamental trees, picnic areas, statues, walking paths, The Glass House (which contained
16250-525: Was passed in Britain as the first nature protection law in the world after extensive lobbying from the Association for the Protection of Seabirds and the respected ornithologist Alfred Newton . Newton was also instrumental in the passage of the first Game laws from 1872, which protected animals during their breeding season so as to prevent the stock from being brought close to extinction. One of
16380-452: Was prompted due to concern over tropical deforestation, disappearing species, and eroding genetic diversity within species. The conference and proceedings that resulted sought to initiate the bridging of a gap between theory in ecology and evolutionary genetics on the one hand and conservation policy and practice on the other. Conservation biology and the concept of biological diversity ( biodiversity ) emerged together, helping crystallize
16510-439: Was ranked among the ten worst zoos in the United States. Systematic reform by 2000 put it on the list of the ten best. By 2020, the United States featured 230 accredited zoos and aquariums across 45 states, accommodating 800,000 animals, and 6,000 species out of which about 1,000 are endangered. The zoos provide 208,000 jobs, and with an annual budget of $ 230 million for wildlife conservation . They attract over 200 million visits
16640-528: Was set up in 1895. A series of national forests and preserves were established by Theodore Roosevelt from 1901 to 1909. The 1916 National Parks Act, included a 'use without impairment' clause, sought by John Muir, which eventually resulted in the removal of a proposal to build a dam in Dinosaur National Monument in 1959. In the 20th century, Canadian civil servants, including Charles Gordon Hewitt and James Harkin , spearheaded
16770-490: Was the first panda born in captivity using artificial insemination in Europe. The zoo is now home to giant pandas Bing Xing (M) and Hua Zui Ba (F), who arrived in Madrid on 8 September 2007. Twin cubs, Po and De De, were born to them on 7 September 2010. They were conceived via artificial insemination. There is a small group of koalas living in the zoo. These animals are kept in a controlled temperature space and are fed with Eucalyptus leaves brought from Huelva. The zoo has
16900-422: Was to educate the entire population with information along modern scientific lines. Zoos were supported by local commercial or scientific societies. The modern zoo that emerged in the 19th century in the United Kingdom , was focused on providing scientific study and later educational exhibits to the public for entertainment and inspiration. A growing fascination for natural history and zoology , coupled with
