Common Horse-chestnut
''Aesculus hippocastanum'', the horse chestnut, is a species of flowering plant in the maple, soapberry and lychee family Sapindaceae. It is a large, deciduous, synoecious (hermaphroditic-flowered) tree. It is also called horse-chestnut, European horsechestnut, buckeye, and conker tree. It is not to be confused with the Spanish chestnut, ''Castanea sativa'', which is a tree in another family, Fagaceae. Description ''Aesculus hippocastanum'' is a large tree, growing to about tall with a domed crown of stout branches. On old trees, the outer branches are often pendulous with curled-up tips. The leaves are opposite and palmately compound, with 5–7 leaflets long, making the whole leaf up to across, with a petiole. The leaf scars left on twigs after the leaves have fallen have a distinctive horseshoe shape, complete with seven "nails". The flowers are usually white with a yellow to pink blotch at the base of the petals; they are produced in spring in erect panicles tall w ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capsule (fruit)
In botany a capsule is a type of simple, dry, though rarely fleshy dehiscent fruit produced by many species of angiosperms (flowering plants). Origins and structure The capsule (Latin: ''capsula'', small box) is derived from a compound (multicarpeled) ovary. A capsule is a structure composed of two or more carpels. In (flowering plants), the term locule (or cell) is used to refer to a chamber within the fruit. Depending on the number of locules in the ovary, fruit can be classified as uni-locular (unilocular), bi-locular, tri-locular or multi-locular. The number of locules present in a gynoecium may be equal to or less than the number of carpels. The locules contain the ovules or seeds and are separated by septa. Dehiscence In most cases the capsule is dehiscent, i.e. at maturity, it splits apart (dehisces) to release the seeds within. A few capsules are indehiscent, for example those of ''Adansonia digitata'', ''Alphitonia'', and '' Merciera''. Capsules are often classif ...

Temperateness
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Gästrikland
Gästrikland () is a historical province or ''landskap'' on the eastern coast of Sweden. It borders Uppland, Västmanland, Dalarna, Hälsingland and the Gulf of Bothnia. Gästrikland is the southernmost of the Norrland provinces. Other forms of the name used are ''Gestricia'' and ''Gastrikland''. Before 1900, the spelling was officially ''Gestrikland'' in Swedish. Administration The traditional provinces of Sweden serve no administrative or political purposes, but are historical and cultural entities. In the case of Gästrikland the province constitutes the southern part of the administrative county, ''län'', Gävleborg County. Heraldry Arms granted in 1560. As with other provinces the arms is represented with a ducal coronet. Blazon: "Argent Hurty an Elk statant Gules attired and hoofed Or." A coat of arms for Gävleborg County was granted in 1938, combining the arms of Gästrikland and Hälsingland. Geography Gästrikland is often called ''the gate to Norrland'' (th ...

Balkan Mixed Forests
The Balkan mixed forests are a terrestrial ecoregion of southeastern Europe according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It belongs in the temperate broadleaf and mixed forests biome and the Palearctic realm. Geography The Balkan mixed forests cover much of the valleys, plains and mountain slopes of the eastern Balkans, mainly Bulgaria, on different altitude, except higher parts of the Rila-Rhodope and Balkan, Mountains, where they are substituted by the Rodope montane mixed forests. It extends from approximately the Drina valley to the coasts of the Black, Marmara and Aegean Seas and occupy 224,400 km² (86,600 sq. mi) in Albania, Bosnia and Herzegovina, Bulgaria, North Macedonia, Serbia, Romania, Greece, Kosovo and Turkey. The ecoregion is surrounded by the Euxine-Colchic deciduous forests (in Turkey, Georgia and Bulgaria), Aegean and Western Turkey sclerophyllous and mixed forests (in Greece), Pindus Mount ...

Pindus Mountains Mixed Forests
The Pindus Mountains mixed forests constitute a terrestrial ecoregion of Europe according to both the WWF and Digital Map of European Ecological Regions by the European Environment Agency. It belongs to the Mediterranean forests, woodlands, and scrub biome, and is in the Palearctic realm. The Pindus Mountains mixed forests are situated in the montane parts of the southern Balkans in the wide altitudinal range above 300–500 m. They cover Taygetus on the Peloponnesus in the south, occur in the mountain ranges of Central Greece (including the Pindus), eastern Albania and the southwestern part of North Macedonia, extend to the Drin River valley in the north and occupy 39,500 km² (15,300 sq. mi) in the three countries.

Native Plant
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Aesculus
The genus ''Aesculus'' ( or ), with species called buckeye and horse chestnut, comprises 13–19 species of flowering plants in the family Sapindaceae. They are trees and shrubs native plant, native to the temperateness, temperate Northern Hemisphere, with six species native to North America and seven to 13 species native to Eurasia. Several Hybrid (biology), hybrids occur. ''Aesculus'' exhibits a classical Arcto-Tertiary Geoflora, Arcto-Tertiary distribution. Ungnadia, Mexican buckeye seedpods resemble the ''Aesculus'' seedpods, but belong to a different genus. Carl Linnaeus named the genus ''Aesculus'' after the Roman name for an edible acorn. Common names for these trees include "buckeye" and "horse chestnut", though they are not in the same order as the true chestnuts, ''Castanea'' in the Fagales. Some are also called white chestnut or red chestnut. In Britain, they are sometimes called conker trees because of their link with the game of conkers, played with the seeds, ...

Deer
Deer or true deer are hoofed ruminant mammals forming the family Cervidae. The two main groups of deer are the Cervinae, including the muntjac, the elk (wapiti), the red deer, and the fallow deer; and the Capreolinae, including the reindeer (caribou), white-tailed deer, the roe deer, and the moose. Male deer of all species (except the water deer), as well as female reindeer, grow and shed new antlers each year. In this they differ from permanently horned antelope, which are part of a different family (Bovidae) within the same order of even-toed ungulates (Artiodactyla). The musk deer (Moschidae) of Asia and chevrotains (Tragulidae) of tropical African and Asian forests are separate families that are also in the ruminant clade Ruminantia; they are not especially closely related to Cervidae. Deer appear in art from Paleolithic cave paintings onwards, and they have played a role in mythology, religion, and literature throughout history, as well as in heraldry, such as ...
