University of Maine Office of Research Administration: Grant Reports
The soil community of Antarctic polar desert is comprised of few endemic species of bacteria, fungi, and invertebrates. Both filamentous and single cellular fungi have been isolated from a diversity of Antarctic soil types, but only yeast appear to be endemic to the polar desert soils. Although the ecological roles of yeast in Antarctic soils is undefined, yeast may be the principal taxa in the heterotrophic communities that synthesize sterols required by soil invertebrates. In addition, yeast may be involved in accumulating and mobilizing growth limiting nutrients such as phosphorus into the polar desert food web. This multidisciplinary research will …
