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 ...
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Representative fauna in tropical deserts include the armadillo lizard, banded Gila monster, bobcat, cactus wren and cactus ferruginous pygmy owl. Moreover, some other animals in deserts including coyote, desert bighorn sheep, desert kangaroo rat, desert tortoise, javelina and Mojave rattlesnake, cougar. Overall, different tropical deserts have ...
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 ...
An abundance of detritivores in the soil allows the ecosystem to efficiently recycle nutrients. [7] Many detritivores live in mature woodland, though the term can be applied to certain bottom-feeders in wet environments. These organisms play a crucial role in benthic ecosystems, forming essential food chains and participating in the nitrogen ...
Like arid deserts, temperatures can vary greatly in semi deserts. They share some characteristics of a true desert and are usually located at the edge of deserts and continental dry areas. They usually receive precipitation from 250 to 500 mm (9.8 to 19.7 in) but this can vary due to evapotranspiration and soil nutrition.
The desert contains a variety of unique endemic plants and animals, notably, the saguaro (Carnegiea gigantea) and organ pipe cactus (Stenocereus thurberi). The Sonoran Desert is clearly distinct from nearby deserts (e.g., the Great Basin , Mojave , and Chihuahuan deserts ) because it provides subtropical warmth in winter and two seasons of ...
The Sahara Desert features a hot desert climate (Köppen climate classification BWh).The Sahara Desert is one of the driest and hottest regions of the world, with a mean temperature sometimes over 30 °C (86 °F) and the average high temperatures in summer are over 40 °C (104 °F) for months at a time, and can even soar to 47 °C (117 °F).
