The Ecological Diversity of the Dry Valleys of Antarctica

Antarctica is an almost uninhabited, ice-lined continent ravaged by cold, windy, and dry situations. Virginia Tech researcher Jeb Barrett contributed in a global collaborative workforce that analyzed biodiversity patterns within the McMurdo Dry Valleys of Antarctica.

These findings had been lately revealed in two separate papers in Communications Biology. An article on biotic interactions analyzes all the community of soil organisms; its companion paper focuses on the soil nematode community utilizing a modeling method.

Traits of Antarctic communities, akin to easy meals webs and low species richness, enable for a higher understanding of the entire neighborhood, from microorganism to multicellular invertebrates.

This analysis is the product of a global collaboration of scientists from half a dozen nations: the USA, New Zealand, Canada, Australia, Nice Britain, and South Africa. Organized by the University of Waikato and the New Zealand Antarctic Program, it’s the first of its variety to check a soil group in its entirety at a regional scale.

The paper based on biotic interactions considers your entire community of soil organisms: cyanobacteria, heterotrophic microorganism, nematodes, and different microscopic invertebrates. The scientists studied the components that decide the abundance and distribution of those organisms, in addition to temperature, distance to the coast, topography, and soil properties, reminiscent of water and pH ranges, of their evaluation.

Biogeochemistry and climate have robust results on biodiversity; however, this new knowledge demonstrated that there are two different vital components. They discovered that biogeography and species interactions are stronger drivers of biodiversity than initially anticipated. Biogeographic processes happen when an organism strikes by space, interacting with its group because it hits. Species interactions, reminiscent of predator-prey relationships and competition, additionally affect biodiversity.
