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 Sahara Desert is the world's largest hot, non-polar desert and is located in North Africa. It extends from the Atlantic Ocean in the west to the Red Sea in the east, and from the Mediterranean Sea in the north to the Sahel savanna in the south. [2] The vast desert encompasses several ecologically distinct regions.
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
The World Wide Fund for Nature highlights a number of desert ecoregions that have a high degree of biodiversity and endemism: [1] 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 Mojave Desert Land Trust is working to scout, catalogue, collect and preserve millions of seeds from 250 species and counting in a race to save an ecosystem.
Sodium nitrate forms through the evaporation of water in desert areas. The richest cache of sodium nitrate is located in South America; approximately 3 million metric tons were mined during World War I. It was the earliest food preservative, and is still used today to cure fish and meat to produce bacon, ham, sausage and deli meats.
The heat stress and die-offs observed in recent years is enough to make horticulturalists like Schilling reconsider what they thought they knew about desert ecosystems.
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 .
