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 ...
In the deeper layers of the NPSG, species higher up on the food chain will migrate vertically or horizontally within or in and out of the gyre. Based on analyses of the zooplankton community, the Central North Pacific has a high species diversity (or high number of species) and high equitability (meaning relatively equal numbers of each exist).
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
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 ...
The temperate Valdivian, matorral, and Magellanic ecoregions are isolated from the subtropical/tropical forests that dominate northern South America by such landscapes as the Atacama desert (north of the matorral), the Andes Mountains, and the dry, rain-shadow Patagonian steppe east of the Andes.
The UAE imports more than 85% of the food it consumes, leaving it vulnerable to supply chain disruptions — something the nation experienced during the Covid-19 pandemic, and the onset of the ...
A great portion of the world's deserts are within the subtropics, as this is where the semi-permanent subtropical anticyclone resides (typically inland on the southwest sides of continents). Areas bordering warm oceans (typically on the southeast sides of continents) have hot and wet summers with frequent (but brief) convective rainfall ...
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.
