The Philippine archipelago is one of the world's great reservoirs of biodiversity and endemism. The archipelago includes over 7000 islands, and a total land area of 300,780 km 2 . The Philippines was never connected to mainland Asia via land bridges , [ dubious – discuss ] so the flora and fauna of the islands had to cross ocean straits to ...
The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
Mindanao is the southernmost large island of the Philippines. The Visayas Islands occupy the center of the Philippines; this ecoregion includes the eastern Visayas - the largest islands of the ecoregion being Leyte, Samar, and Bohol. There are also a number of smaller islands, including Camiguin, Basilan, and Dinagat. The lowland forests are ...
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid.
Grasslands are dominated by grasses and other herbaceous plants. Savannas are grasslands with scattered trees. Shrublands are dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover.
Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions. Saguaro cacti and agave have both suffered in sweltering ...
Tropical heat generates unstable air in this area, and air masses become extremely dry due to the loss of moisture during the process of tropical ascent. [1] Hadley cell above Sahara desert. Another significant determinant of tropical desert climate are Hadley cells. Hadley cells concentrate all precipitations in the hotter humid lower pressure ...
