A benefit of a specialist species is that because the species has a more clearly defined niche, this reduces competition from other species. On the other hand, generalist species, by their nature, cannot realize as much resources from one niche, but instead find resources from many. Because other species can also be generalists, there is more ...
Adjacent to the BMGR is the Cabeza Prieta National Wildlife Refuge (CPNWR), also a critical breeding area for this species. Parts of the CPNWR are off limits to visitors between mid-March and mid-July, during the fawning season, so as to minimize disturbance to herds with fawns, which can result in the loss of fawns.

The Scots pine (Pinus sylvestris) has 20 different ecotypes in an area from Scotland to Siberia, all capable of interbreeding. [ 59 ] Ecotype distinctions can be subtle and do not always require large distances; it has been observed that two populations of the same Helix snail species separated by only a few hundred kilometers prefer not to ...
Evaporites are found in the US's Great Basin Desert, historically exploited by the "20-mule teams" pulling carts of borax from Death Valley to the nearest railway. [105] A desert especially rich in mineral salts is the Atacama Desert, Chile, where sodium nitrate has been mined for explosives and fertilizer since around 1850. [105]
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 ...
Now it is only found in fragmented and isolated regions in the southwest of the country, as a result of widespread deforestation in the 20th century. [43] As habitat destruction of an area occurs, the species diversity offsets from a combination of habitat generalists and specialists to a population primarily consisting of generalist species. [3]
Many species fall somewhere between generalist and specialist on the generalist-specialist range. Such species generally exhibit moderate environmental specialization, being neither pure generalists nor pure specialists, resulting in fluid changes that must be evaluated when categorizing species.
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 ...
