Desert habitats receive less than 10 inches of rain per year. Many deserts receive much less rainfall. Desert categories are hot and dry, semi-arid, coastal and cold. The highest recorded temperature, 134°F, occurred in a hot desert at Furnace Creek, Death Valley, USA, in 1913. On the ...

These sandy desert regions also support lacertid lizards ( Acanthodactylus ) with fringed toes and shovel noses. Far away in the Southern Hemisphere, on windblown dunes of the Namib desert of southwestern Africa, an independent lineage of lacertids has evolved a similar life form, Meroles ...

Most primarily selfing species are small annuals in variable or disturbed habitats, with small, drab flowers. Most desert annuals and roadside weeds, for example, are selfers. The evolutionary transition from outcrossing to near-complete selfing has occurred many times in flowering plants. ...
The rate of increase in weight and size of plant organs, such as leaf, stem, or root. Skin damage: Beside the sunburn (erythema), a well-known acute effect, chronic skin damage is also observed. This includes elastoses (damage of collagen fibers) and, thereby, aging of the skin and ...
