The McMurdo Dry Valleys region of Antarctica is a polar desert characterized by extremely low annual precipitation (<100 mm (3.9 in)) and an absence of vascular plants and vertebrates; microbial activity dominates biological functioning. [2]
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. [2] If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.

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 Handbook of Australian, New Zealand and Antarctic Birds, known as HANZAB, is the pre-eminent scientific reference on birds in the region, which includes Australia, New Zealand, Antarctica, and the surrounding ocean and subantarctic islands. It attempts to collate all that is known about each of the 957 species recorded.
Population density and economic disparities shape mental health . Environmental psychology is a branch of psychology that explores the relationship between humans and the external world. It examines the way in which the natural environment and our built environments shape us as individuals.
Around 98% of continental Antarctica is covered in ice up to 4.7 kilometres (2.9 mi) thick. [1] Antarctica's icy deserts have extremely low temperatures, high solar radiation, and extreme dryness. [2] Any precipitation that does fall usually falls as snow, and is restricted to a band around 300 kilometres (186 mi) from the coast.
