Central Asian Riparian Woodlands
The Central Asian riparian woodlands ecoregion (WWF ID: PA1311) is spread out across the deserts and plains of central Asia between the Aral Sea and the mountains to the east. The long narrow components of the ecoregion follow the large rivers fed by snowmelt, and provide critical habitat for migratory birds as they travel through the arid region. The vegetation is referred to as tugai, characterized by low tangles of trees and brush along the edges of the rivers and associated wetlands, and fed by groundwater instead of precipitation. Location and description Major river systems that support habitat for this ecoregion include: * The Syr Darya (River), which flows westward for over from the Tian Shan Mountains across eastern Uzbekistan and southern Kazakhstan to the Aral Sea. * The Amu Darya (River), which runs parallel to and south of the Syr Darya; the Amu Darya flows out of Afghanistan and Tajikistan northwest along the border of Uzbekistan and Turkmenistan. * The Murgha ...

Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

Cotoneaster
''Cotoneaster'' is a genus of flowering plants in the rose family, Rosaceae, native to the Palaearctic region (temperate Asia, Europe, north Africa), with a strong concentration of diversity in the genus in the mountains of southwestern China and the Himalayas.Flora of China''Cotoneaster''(includes most of the world's ''Cotoneaster'' species) ''www.efloras.org'' They are related to hawthorns (''Crataegus''), firethorns (''Pyracantha''), photinias (''Photinia''), and rowans (''Sorbus''). Depending on the species definition used, between 70 and 300 different species of ''Cotoneaster'' are described, with many apomictic microspecies treated as species by some authors, but only as varieties by others.Bean, W. J. (1976). ''Trees and Shrubs Hardy in the British Isles'' 8th edition. John Murray . The majority of species are shrubs from tall, varying from ground-hugging prostrate plants to erect shrubs; a few, notably ''C. frigidus'', are small trees up to tall and trunk diameter. ...

Honeysuckle
Honeysuckles are arching shrubs or twining vines in the genus ''Lonicera'' () of the family Caprifoliaceae, native to northern latitudes in North America and Eurasia. Approximately 180 species of honeysuckle have been identified in both continents. Widely known species include ''Lonicera periclymenum'' (common honeysuckle or woodbine), ''Lonicera japonica'' (Japanese honeysuckle, white honeysuckle, or Chinese honeysuckle) and ''Lonicera sempervirens'' (coral honeysuckle, trumpet honeysuckle, or woodbine honeysuckle). ''L. japonica'' is an aggressive, highly invasive species considered a significant pest on the continents of North America, Europe, South America, Australia, and Africa. Some species are highly fragrant and colorful, so are cultivated as ornamental garden plants. In North America, hummingbirds are attracted to the flowers, especially ''L. sempervirens'' and ''L. ciliosa'' (orange honeysuckle). Honeysuckle derives its name from the edible sweet nectar obtainable fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berberis
''Berberis'' (), commonly known as barberry, is a large genus of deciduous and evergreen shrubs from tall, found throughout Temperateness, temperate and subtropical regions of the world (apart from Australia). Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known ''Berberis'' species is the European barberry, ''Berberis vulgaris'', which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America. Many of the species have Spine (botany), spines on the shoots and all along the margins of the leaves. Description The genus ''Berberis'' has dimorphic shoots: long shoots which form the structure of the plant, and short shoots only long. The leaf, leaves on long shoots are non-Photosynthesis, photosynthetic, developed into one to three or more spines long. The bud in the axil of each thorn-leaf then develops a short shoot with several normal, phot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippophae Rhamnoides
''Hippophae rhamnoides'', also known as sea-buckthorn, is a species of flowering plant in the family Elaeagnaceae, native to the cold-temperate regions of Europe and Asia. It is a spiny deciduous shrub. The plant is used in the food and cosmetics industries, in traditional medicine, as animal fodder, in horticulture, and for ecological purposes. Description and biology ''Hippophae rhamnoides'' is a hardy, deciduous shrub that can grow between 2 and 4 m high (between 7 and 13 ft). It has a rough, brown or black bark and a thick, grayish-green crown. The leaves are alternate, narrow and lanceolate, with silvery-green upper faces. It is dioecious, meaning that the male and female flowers grow on different shrubs. The sex of seedlings can only be determined at the first flowering, which mostly occurs after three years. The male inflorescence is built up of four to six apetalous flowers, while the female inflorescence normally consists of only one apetalous flower and co ...

Tamarix
The genus ''Tamarix'' (tamarisk, salt cedar, taray) is composed of about 50–60 species of flowering plants in the family Tamaricaceae, native to drier areas of Eurasia and Africa. The generic name originated in Latin and may refer to the Tamaris River in Hispania Tarraconensis (Spain). Description They are evergreen or deciduous shrubs or trees growing to in height and forming dense thickets. The largest, ''Tamarix aphylla'', is an evergreen tree that can grow to tall. They usually grow on saline soils, tolerating up to 15,000 ppm soluble salt, and can also tolerate alkaline conditions. Tamarisks are characterized by slender branches and grey-green foliage. The bark of young branches is smooth and reddish brown. As the plants age, the bark becomes gray-brown, ridged and furrowed. The leaves are scale-like, almost like that of junipers, 1–2 mm (1/20" to 1/10") long, and overlap each other along the stem. They are often encrusted with salt secretions. The pink to w ...

Elaeagnus
''Elaeagnus'' , silverberry or oleaster, is a genus of about 50–70 species of flowering plants in the family Elaeagnaceae. Description ''Elaeagnus'' plants are deciduous or evergreen shrubs or small trees. The alternate leaves and the shoots are usually covered with tiny silvery to brownish scales, giving the plants a whitish to grey-brown colour from a distance. The flowers are small, with a four-lobed calyx and no petals; they are often fragrant. The fruit is a fleshy drupe containing a single seed; it is edible in many species. Several species are cultivated for their fruit, including ''E. angustifolia'', ''E. umbellata'', and ''E. multiflora'' (gumi). ''E. umbellata'' contains the carotenoid lycopene. Taxonomy The genus ''Elaeagnus'' was erected in 1754 by Carl Linnaeus, who attributed the name to Joseph Pitton de Tournefort. There is agreement that the name is based on Theophrastus's use of the Ancient Greek (, latinized to ) as the name of a shrub. The first part of ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...
