Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Broadleaf And Mixed Forests
Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions. These forests are richest and most distinctive in central China and eastern North America, with some other globally distinctive ecoregions in the Caucasus, the Himalayas, Southern Europe, Australasia, Southwestern South America and the Russian Far East. Ecology The typical structure of these forests includes four layers. * The uppermost layer is the canopy composed of tall mature trees ranging from high. Below the canopy is the three-layered, shade-tolerant understory that is roughly shorter than the canopy. * The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. * Below the sub-canopy is the shrub layer, composed of low grow ...

Temperate Coniferous Forests
Temperate coniferous forest is a terrestrial biome defined by the World Wide Fund for Nature. Temperate coniferous forests are found predominantly in areas with warm summers and cool winters, and vary in their kinds of plant life. In some, needleleaf trees dominate, while others are home primarily to broadleaf evergreen trees or a mix of both tree types. A separate habitat type, the tropical coniferous forests, occurs in more tropical climates. Temperate coniferous forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or montane areas. Many species of trees inhabit these forests including pine, cedar, fir, and redwood. The understory also contains a wide variety of herbaceous and shrub species. Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions. Structurally, these forests are rather si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarim Basin Deciduous Forests And Steppe
The Tarim Basin deciduous forests and steppe is a temperate broadleaf and mixed forests ecoregion in the Xinjiang Uyghur Autonomous Region of western China. The ecoregion includes deciduous riparian forests and steppes sustained by the region's rivers in an otherwise arid region. Geography The Tarim Basin is a desert basin lying in westernmost China. The basin is surrounded by high mountains – the Kunlun Mountains to the south, which form the northern edge of the Tibetan Plateau; the Pamir Mountains to the west; and the Tian Shan to the north. The basin is arid, but the surrounding mountains receive considerable rainfall and snow. Rivers drain into the basin from the mountains, including the northward-flowing Hotan River, which drains the western Kunlun Mountains, the Yarkand River, which drains the Pamirs, and the Aksu River, which drains the western Tian Shan mountains. These rivers join to form the Tarim River, which flows for 1300 km in an arc across the northern and easte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sichuan Basin Evergreen Broadleaf Forests
The Sichuan Basin evergreen broadleaf forests are a critically endangered WWF ecoregion. The ecoregion occupies the Sichuan Basin in China and covers an area of . The broadleaf forest habitat once covered the Sichuan Basin, but today is limited to mountains and preserved temple grounds in the basin and around the basin's rim. An especially well-preserved example of remaining forest exists on Mount Emei at the western edge of the Sichuan Basin. The original forests are thought to have been made up of subtropical oaks, laurels, and Schima. Much of the remaining Sichuan Basin has been converted to anthropogenic agricultural use in the last 5,000 years. Fauna Endangered and critically endangered animal species that have traditionally inhabited the Sichuan Basin evergreen broadleaf forests include: Amphibians * Boulenger's paa frog * Chinese giant salamander * Chinting lazy toad * Omei lazy toad Birds * Baer's pochard * Far Eastern curlew * Oriental stork * Scaly-sided mer ...
