The data and model described here with the purpose of understanding controls over biodiversity. A multi-scale approach to understand how local and regional factors affect the community assembly processes that drive emergent patterns.
Dispersal of soil organisms is crucial for their spatial distribution and adaptation to the prevailing conditions of the Antarctic Dry Valleys. This study investigate the possibility of wind dispersal of soil invertebrates within the dry valleys. Soil invertebrates were evaluated in wind-transported dust particles in collection pans (Bundt pans) 100 cm above the soil surface. Three species of nematode were recovered and Scottnema lindsayae was the most dominant. There were more juveniles (71%) in the transported sediments than adults (29%).
