However, the same test also revealed that native Dutch speakers understood 63.9% of a spoken Frisian text, 59.4% of a spoken Afrikaans text and 89.4% of a spoken Dutch text, read aloud by native speakers of the respective languages. The saying "As milk is to cheese, are English and Fries" describes the observed similarity between Frisian and English. One rhyme that is sometimes used to demonstrate
231-399: A behavior known as " marcescence " whereby dead leaves are not shed in the fall and remain on the tree until being blown off by the weather. This is caused by incomplete development of the abscission layer. It is mainly seen in the seedling and sapling stage, although mature trees may have marcescence of leaves on the lower branches. A number of deciduous plants remove nitrogen and carbon from
308-797: A disturbance or fire. Birches are early tree species to become established in primary successions , and can become a threat to heathland if the seedlings and saplings are not suppressed by grazing or periodic burning. Birches are generally lowland species, but some species, such as Betula nana , have a montane distribution. In the British Isles , there is some difference between the environments of Betula pendula and Betula pubescens , and some hybridization, though both are "opportunists in steady-state woodland systems". Mycorrhizal fungi , including sheathing (ecto)mycorrhizas, are found in some cases to be beneficial to tree growth. A large number of lepidopteran insects feed on birch foliage. Because of

The deciduous characteristic has developed repeatedly among woody plants. Trees include maple , many oaks and nothofagus , elm , beech , aspen , and birch , among others, as well as a number of coniferous genera , such as larch and Metasequoia . Deciduous shrubs include honeysuckle , viburnum , and many others. Most temperate woody vines are also deciduous, including grapes , poison ivy , Virginia creeper , wisteria , etc. The characteristic

His example was not followed until the 19th century, when entire generations of Frisian authors and poets appeared. This coincided with the introduction of the so-called newer breaking system, a prominent grammatical feature in almost all West Frisian dialects, with
693-571: A slightly weeping habit. Other species with ornamental white bark include Betula ermanii , Betula papyrifera , Betula pendula and Betula raddeana . In the European Union, a prescription gel containing birch bark extract (commercial name Episalvan , betulae cortex dry extract (5–10 : 1); extraction solvent: n -heptane 95% (w/w)) was approved in 2016 for the topical treatment of minor skin wounds in adults. Although its mechanism of action in helping to heal injured skin
770-606: Is a deciduous woody shrub found in Japan . Forests where a majority of the trees lose their foliage at the end of the typical growing season are called deciduous forests. These forests are found in many areas worldwide and have distinctive ecosystems, understory growth, and soil dynamics. Two distinctive types of deciduous forests are found growing around the world. Temperate deciduous forest biomes are plant communities distributed in North and South America, Asia, Southern slopes of
847-453: Is a small samara , although the wings may be obscure in some species. They differ from the alders ( Alnus , another genus in the family) in that the female catkins are not woody and disintegrate at maturity, falling apart to release the seeds, unlike the woody, cone-like female alder catkins. The bark of all birches is characteristically marked with long, horizontal lenticels , and often separates into thin, papery plates, especially upon

When autumn arrives and the days are shorter or when plants are drought-stressed, the chlorophyll steadily breaks down, allowing other pigments present in the leaf to become apparent and resulting in non-green colored foliage. The brightest leaf colors are produced when days grow short and nights are cool, but remain above freezing. These other pigments include carotenoids that are yellow, brown, and orange. Anthocyanin pigments produce red and purple colors, though they are not always present in
1001-666: Is compressed, two-celled, and crowned with two slender styles; the ovule is solitary. Each scale bears a single small, winged nut that is oval, with two persistent stigmas at the apex. Betula species are organised into five subgenera. Note: many American texts have B. pendula and B. pubescens confused, though they are distinct species with different chromosome numbers. The common name birch comes from Old English birce , bierce , from Proto-Germanic * berk-jōn (cf. German Birke , West Frisian bjirk ), an adjectival formation from * berkōn (cf. Dutch berk , Low German Bark , Danish birk , Norwegian bjørk ), itself from
1078-399: Is fair. The flowers are monoecious , and open with or before the leaves. Once fully grown, these leaves are usually 3–6 millimetres ( 1 ⁄ 8 – 1 ⁄ 4 in) long on three-flowered clusters in the axils of the scales of drooping or erect catkins or aments. Staminate catkins are pendulous, clustered, or solitary in the axils of the last leaves of the branch of the year or near
1155-400: Is formed between the leaf petiole and the stem. This layer is formed in the spring during active new growth of the leaf; it consists of layers of cells that can separate from each other. The cells are sensitive to a plant hormone called auxin that is produced by the leaf and other parts of the plant. When auxin coming from the leaf is produced at a rate consistent with that from the body of
1232-613: Is highly adaptive and able to sustain harsh conditions with casual indifference. Proof of this adaptability is seen in its easy and eager ability to repopulate areas damaged by forest fires or clearings. Birches are also associated with Tír na nÓg , the land of the dead and the Sidhe , in Gaelic folklore, and as such frequently appear in Scottish, Irish, and English folksongs and ballads in association with death, or fairies, or returning from
1309-864: Is named after the birch. The generic name Betula is from Latin , which is a diminutive borrowed from Gaulish betua (cf. Old Irish bethe , Welsh bedw ). Within Betulaceae, birches are most closely related to alder. The oldest known birch fossils are those of Betula leopoldae from the Klondike Mountain Formation in Washington State, US, which date to the early Eocene ( Ypresian ) around 49 million years ago. Birches often form even-aged stands on light, well-drained, particularly acidic soils . They are regarded as pioneer species , rapidly colonizing open ground especially in secondary successional sequences following

Here is a short example of the West Frisian language in comparison with English , Old English , and Dutch . Not all Frisian varieties spoken in Dutch Friesland are mutually intelligible . The varieties on

Preliminary research indicates that the phytochemicals , betulin and possibly other triterpenes , are active in Episalvan gel and wound healing properties of birch bark. Over centuries, birch bark was used in traditional medicine practices by North American indigenous people for treating superficial wounds by applying bark directly to
1617-714: Is the most widely spoken of the Frisian languages . In the study of the evolution of English , West Frisian is notable as being the most closely related foreign tongue to the various dialects of Old English spoken across the Heptarchy , these being part of the Anglo-Frisian branch of the West Germanic family. The name "West Frisian" is only used outside the Netherlands, to distinguish this language from

Periods of leaf fall often coincide with seasons: winter in the case of cool-climate plants or the dry-season in the case of tropical plants, however there are no deciduous species among tree-like monocotyledonous plants, e.g. palms , yuccas , and dracaenas . The hydrangea hirta
1771-551: The Habsburg rulers of the Netherlands ( Charles V, Holy Roman Emperor , and his son Philip II, King of Spain ). When the Netherlands became independent in 1585 , West Frisian did not regain its former status, because Holland rose as the dominant part of the Netherlands and its language, Dutch, as the dominant language in judicial, administrative and religious affairs. In this period the Frisian poet Gysbert Japiks (1603–1666),
1848-515: The Ingvaeonic sound shift, which affected Frisian and English, but the other West Germanic varieties hardly at all. Both English and Frisian are marked by the suppression of the Germanic nasal in a word like us ( ús ), soft ( sêft ) or goose ( goes ): see Ingvaeonic nasal spirant law . Also, when followed by some vowels the Germanic k developed into a ch sound. For example,
1925-574: The Northern Hemisphere , particularly in northern areas of temperate climates and in boreal climates . Birch wood is used for a wide range of purposes. Birch species are generally small to medium-sized trees or shrubs , mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets . The fruit

This root is presumably derived from * bʰreh₁ǵ- 'to shine, whiten', in reference to the birch's white bark. The Proto-Germanic rune berkanan
2079-553: The autumn ; to the shedding of petals , after flowering; and to the shedding of ripe fruit . The antonym of deciduous in the botanical sense is evergreen . Generally, the term "deciduous" means "the dropping of a part that is no longer needed or useful" and the "falling away after its purpose is finished". In plants, it is the result of natural processes. "Deciduous" has a similar meaning when referring to animal parts, such as deciduous antlers in deer , deciduous teeth (baby teeth) in some mammals (including humans); or decidua ,
2156-456: The dry season or other seasons, depending on variations in rainfall . The converse of deciduous is evergreen , where foliage is shed on a different schedule from deciduous plants, therefore appearing to remain green year round because not all the leaves are shed at the same time. Plants that are intermediate may be called semi-deciduous ; they lose old foliage as new growth begins. Other plants are semi-evergreen and lose their leaves before
2233-503: The foliage before they are shed and store them in the form of proteins in the vacuoles of parenchyma cells in the roots and the inner bark. In the spring, these proteins are used as a nitrogen source during the growth of new leaves or flowers. Plants with deciduous foliage have advantages and disadvantages compared to plants with evergreen foliage. Since deciduous plants lose their leaves to conserve water or to better survive winter weather conditions, they must regrow new foliage during
2310-409: The paper birch . Distinctive colors give the common names gray , white , black , silver and yellow birch to different species. The buds, forming early and full-grown by midsummer, are all lateral, without a terminal bud forming; the branch is prolonged by the upper lateral bud. The wood of all the species is close-grained with a satiny texture and capable of taking a fine polish; its fuel value

2464-464: The 16th century, West Frisian was widely spoken and written, but from 1500 onwards it became an almost exclusively oral language, mainly used in rural areas. This was in part due to the occupation of its stronghold, the Dutch province of Friesland ( Fryslân ), in 1498, by Albert III, Duke of Saxony , who replaced West Frisian as the language of government with Dutch. This practice was continued under
2541-460: The 1970s. Frisian is still spoken by some Dutch Canadians , Dutch Americans , Dutch Australians and Dutch New Zealanders . Apart from the use of West Frisian as a first language, it is also spoken as a second language by about 120,000 people in the province of Friesland. West Frisian is considered by UNESCO to be a language in danger of becoming extinct , officially listed as "vulnerable". In 1951, Frisian language activists, protesting at

Other differences are in the pronunciation of the diphthongs ei , ai , and aai which are pronounced ij , ai , and aai in Wood Frisian, but ôi , òi , and ôi in Clay Frisian. Thus, in Wood Frisian, there
2695-589: The Frisian landscape. In the western and north-western parts of the province, the region where Clay Frisian is spoken, the soil is made up of thick marine clay, hence the name. While in the Clay Frisian-speaking area ditches are used to separate the pastures, in the eastern part of the province, where the soil is sandy, and water sinks away much faster, rows of trees are used to that purpose. The natural landscape in which Wâldfrysk exists mirrors The Weald and North Weald areas of south-eastern England –
2772-418: The Frisian language was spoken along the entire southern North Sea coast. Today this region is sometimes referred to as "Greater Frisia " or Frisia Magna , and many of the areas within it still treasure their Frisian heritage, even though in most places the Frisian language has been lost. Old Frisian bore a striking similarity to Old English . This similarity was reinforced in the late Middle Ages by
2849-428: The Germanic words wald and weald are cognate. Although Klaaifrysk and Wâldfrysk are mutually very easily intelligible, there are, at least to native West Frisian speakers, a few very conspicuous differences. These include the pronunciation of the words my ("me"), dy ("thee"), hy ("he"), sy ("she" or "they"), wy ("we") and by ("by"), and the diphthongs ei and aai . Of

Growth occurs during warm summers, leaf drop in autumn, and dormancy during cold winters. These seasonally distinctive communities have diverse life forms that are impacted greatly by the seasonality of their climate, mainly temperature and precipitation rates. These varying and regionally different ecological conditions produce distinctive forest plant communities in different regions. Tropical and subtropical deciduous forest biomes have developed in response not to seasonal temperature variations but to seasonal rainfall patterns. During prolonged dry periods
3003-489: The Old Frisian period ( c. 1150 – c. 1550 ) grammatical cases still occurred. Some of the texts that are preserved from this period are from the 12th or 13th, but most are from the 14th and 15th centuries. Generally, these texts are restricted to legal documents. Although the earliest definite written examples of Frisian are from approximately the 9th century, there are a few runic inscriptions from

To protect the city against future fires, wide avenues were created, and these were lined with silver birch trees all over the city. Umeå later adopted the unofficial name of "City of the Birches ( Björkarnas stad )". Also,
3157-453: The West Frisian for cheese and church is tsiis and tsjerke , whereas in Dutch they are kaas and kerk . Modern English and Frisian on the other hand have become very divergent, largely due to wholesale Norse and French imports into English and similarly heavy Dutch and Low German influences on Frisian.

However, for most temperate regions it takes place in late September through early November and in subtropical climates such as the southern US, it may be November into December. Leaf drop or abscission involves complex physiological signals and changes within plants. When leafout

The scales of the mature staminate catkins are broadly ovate, rounded, yellow or orange colour below the middle and dark chestnut brown at apex. Each scale bears two bractlets and three sterile flowers, each flower consisting of a sessile, membranous, usually two-lobed, calyx. Each calyx bears four short filaments with one-celled anthers or strictly, two filaments divided into two branches, each bearing

This committee recommended that the Frisian language should receive legal status as a minority language. Subsequently, the Use of Frisian in Legal Transactions Act of 11 May 1956 was passed, which provided for the use of Frisian in transactions with the courts. Since 1956, West Frisian has an official status along with and equal to Dutch in

( See also : Autumn leaf color ) Most of the Southern Hemisphere lacks deciduous plants due to its milder winters and smaller landmass, most of which is nearer the equator with only far southern South America and the southern island of New Zealand producing distinct fall colors. The beginnings of leaf drop starts when an abscission layer
3927-591: The flowers can be damaged by frost or, in dry season regions, result in water stress on the plant. Spring leafout and fall leaf drop are triggered by a combination of daylight and air temperatures. The exact conditions required will vary with the species, but generally more cold-tolerant genera such as Salix will leaf-out earlier and lose their leaves later, while genera such as Fraxinus and Juglans can only grow in warm, frost-free conditions so they need at least 13 hours of daylight and air temperatures of around 70 °F (21 °C) to leaf out. They will be among

It can be dried and ground into flour, as was done by Native Americans and early settlers. It can also be cut into strips and cooked like noodles. The sap can be drunk or used to make syrup and birch beer . Tea can be made from

It is also a factor that the continental United States and southern Canada are at a lower latitude than northern Europe, so the sun during the fall months is higher and stronger. This combination of strong sun and cool temperatures leads to more intense fall colors. The Southern United States also has poor fall colors due to warm temperatures during

Therefore, possibly as many as 150,000 West Frisian speakers live in other Dutch provinces, particularly in the urban agglomeration in the West, and in neighbouring Groningen and newly reclaimed Flevoland . A Frisian diaspora exists abroad; Friesland sent more emigrants than any other Dutch province between the Second World War and

Parts of the world that have showy displays of bright autumn colors are limited to locations where days become short and nights are cool. The New England region of the United States and southeastern Canada tend to produce particularly good autumn colors for this reason, with Europe producing generally poorer colors due to
4697-412: The next growing season, retaining some during winter or dry periods. Many deciduous plants flower during the period when they are leafless, as this increases the effectiveness of pollination . The absence of leaves improves wind transmission of pollen for wind-pollinated plants and increases the visibility of the flowers to insects in insect-pollinated plants. This strategy is not without risks, as
SECTION 60
#17327938929774774-783: The next suitable growing season; this uses resources which evergreens do not need to expend. Evergreens suffer greater water loss during the winter and they also can experience greater predation pressure , especially when small. Deciduous trees experience much less branch and trunk breakage from glaze ice storms when leafless, and plants can reduce water loss due to the reduction in availability of liquid water during cold winter days. Losing leaves in winter may reduce damage from insects; repairing leaves and keeping them functional may be more costly than just losing and regrowing them. Removing leaves also reduces cavitation which can damage xylem vessels in plants. This then allows deciduous plants to have xylem vessels with larger diameters and therefore

Most speakers of West Frisian live in the province of Friesland in the north of the Netherlands . Friesland has 643,000 inhabitants (2005), of whom 94% can understand spoken West Frisian, 74% can speak West Frisian, 75% can read West Frisian, and 27% can write it. For over half of

In the same year, West Frisian became an official school subject, having been introduced to primary education as an optional extra in 1937. It was not until 1980, however, that West Frisian had the status of a required subject in primary schools, and not until 1993 that it

The elongation of these cells breaks the connection between the different cell layers, allowing the leaf to break away from the plant. It also forms a layer that seals the break, so the plant does not lose sap. Some trees, particularly oaks and beeches, exhibit
