Palawan rainforestsLast Updated on 2014-04-17 14:03:23
Palawan represents a bridge between the Sunda Shelf and Philippine bioregions and contains faunal elements from both, as well as it own unique elements. This ecoregion, though more intact than any other region in the Philippines is under great pressure from logging interests.
This ecoregion includes the island Palawan plus Balabac, Ursula Island, and the Calamian Group. Palawan itself is the sixth largest of the Philippine Islands. The climate of the ecoregion is tropical wet. In northwest Palawan, a dry season lasts from November to May while the wet season lasts from June to October; the rest of the island experiences a short, one- to three-month dry season. The east coast becomes progressively drier than the west coast from north to south.
Palawan (along with the Calamianes and the island of Mindoro) was rifted (below water) from the Asian mainland approximately 32 million... More »

Class:------ Aves (Birds)
Family:-------- Spheniscidae (Penguins)
Genus:--------- Aptenodytes (Great Penguins)
Species:--------- Aptenodytes forsteri G. R. Gray, 1844
Like all penguins, the Emperor penguin is characterized by its erect posture, stiff wings, excellent swimming ability, awkward movement out of water, and coloring. The black back and white front, make penguins difficult to... More »
Windward Islands dry forestsLast Updated on 2013-11-01 10:33:27The Windward Islands dry forests ecoregion is sparsely distributed among the Windward Island Group of the Caribbean’s Lesser Antilles. It is typically found as an intermediate gradient between the more mesichabitat characterized by moderate soil moisture, high-elevation forests and the xeric, coastal areas. Much of this ecoregion has been substantially altered by shifting cultivation. Many areas that were once dry evergreen or semi-evergreen seasonal forest, are now cultivated and dominated by farms, rural villages, roads, pastures and banana tree patches. This ecoregion shares flora and fauna with adjacent moist forests and, in some areas, with species native to coastal habitats. Arid coastal areas and inaccessible interior mountains put a disproportionate amount of human-related pressures (i.e., agricultural expansion, roads, buildings) on this ecoregion. Consequently,...

Antarctic PeninsulaLast Updated on 2013-10-01 23:21:36
The Antarctic Peninsula is the northernmost element of mainland Antarctica, and the only part of the continent of Antarctica that extends outside the Antarctic Circle.
It is approximately 1200 miles (2000 km) long, stretching from 75°S (a drawn between Cape Adams (Weddell Sea) and a point on the mainland south of Eklund Islands) to 63°S (Prime Head on the Trinity Peninsula). The southern tip of South America, Cape Horn is about 610 miles (980 km) farther north, and is separated by the Drake Passage.
Other names applying to the region include: Tierra de O'Higgins (Chile), Tierra de San Martín (Argentina) and Península Antártica (other Spanish speaking countries). It has the mildest climate in Antarctica and contains the only two flowering plant species on the entire continent.
While Argentina, Chile and the United Kingdom have made... More »
Amur RiverLast Updated on 2013-09-30 16:59:28The Amur River, considered the Earth's tenth largest watercourse, has its headwaters in western Manchuria and mouth at the Strait of Tartary, which connects the Sea of Japan with the Okhotsk Sea. Much of its length defines the border between Russia and China.
Although the generally level topography has made this basin vulnerable to heavy exploitation by agriculture, the region boasts many endemic species of fish, and its wetlands are important to a number of species of rare and endangered birds.
The Amur River became contaminated by a massive toxic release on the Chinese side of the catchment basin in 2005, which effects still linger to the current time. Similarly there are extensive deposits of mercury in Amur River sediments, residual from the central planning poor management practises of the communist Soviet era.
The length of the Amur River is 2825 kilometers, a river... More »
