Antarctica is one of the most physically and chemically extreme terrestrial environments to be inhabited by lifeforms. [1] The largest plants are mosses, and the largest animals that do not leave the continent are a few species of insects. Microbiome on the High Antarctic Plateau
Antarctica is in the Southern Hemisphere and it also contains the land mass, surrounding islands and the ocean. Polar regions also contain the subantarctic and subarctic zone which separate the polar regions from the temperate regions. Antarctica and the Arctic lie in the polar circles. The polar circles are imaginary lines shown on maps to be ...
Antarctica: Compiled from All Available Sources to 1943, Including the Results of All American Expeditions from the United States Exploring Expedition 1839–1841 to the United States Antarctic Service 1940–1941. [4] Antarctica in the International Geophysical Year: Based on a Symposium on the Antarctic. [5]
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 ...
David Senchina notes that Hooker was the first botanist to set foot on Antarctica, in 1840; the first sighting of a plant on the continent was only a few years earlier, namely A. Young's observation of Deschampsia antarctica (Antarctic hair grass) in 1819, from HMS Andromache, and the first plant specimen from an Antarctic island had been ...
The oceans themselves are a more stable environment for life, both in the water column and on the seabed. There is relatively little diversity in Antarctica compared to much of the rest of the world. Terrestrial life is concentrated in areas near the coast. Flying birds nest on the milder shores of the Peninsula and the subantarctic islands.
The continent of Antarctica is so cold that it has supported only 2 vascular plants for millions of years, and its flora presently consists of around 250 lichens, 100 mosses, 25–30 liverworts, and around 700 terrestrial and aquatic algal species, which live on the areas of exposed rock and soil around the shore of the continent.
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.
