Amazon River near Manaus, Brazil, an example of a lowland river habitat. The generally more turbid, warm, slow-flowing waters and fine sediment beds of lowland rivers encourage fish species with broad temperature tolerances and greater tolerances to low oxygen levels, and life history and breeding strategies adapted to these and other traits of lowland rivers.
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
Regions with sparse vegetation and a low vegetation index are shown in tan. Based on measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. Areas where there is no data are gray. [1] Vegetation is an assemblage of plant species and the ground cover they provide. [2]
The Columbia Plateau in southern British Columbia, Oregon, Idaho, and Washington state, is an example of a steppe region in North America outside of the Great Plains. In South America , cold steppe can be found in Patagonia and much of the high elevation regions east of the southern Andes .
The Pampas (from the Quechua: pampa, meaning "plain"), also known as the Pampas Plain, are fertile South American low grasslands that cover more than 1,200,000 square kilometres (460,000 sq mi) and include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, Entre Ríos, and Córdoba; all of Uruguay; and Brazil's southernmost state, Rio Grande do Sul.
Coastal plains can form in one of two ways; some begin as a continental shelf, a flat piece of land located below sea level, and are created when the ocean level falls, exposing the land. Others develop when river currents carry sediment into the ocean, which is deposited and builds up over time until it forms a coastal plain.
There are three regions and associated types of tundra: Arctic, [2] Alpine, [2] and Antarctic. [3] Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline
The Tropical Wet Forests ecoregion in North America includes the southern tip of the Florida Peninsula in the United States; within Mexico, the Gulf Coastal Plain, the western and southern part of the Pacific Coastal Plain, most of the Yucatán Peninsula and the lowlands of the Chiapas Sierra Madre, which continue south to Central and South ...
