Abstract The meltwater streams of the McMurdo Dry Valleys are hot spots of biological diversity in the climate-sensitive polar desert landscape. Microbial mats, largely comprised of cyanobacteria, dominate the streams which flow for a brief window of

Stream biogeochemical and suspended sediment responses to permafrost degradation in stream banks in Taylor Valley, Antarctica
Autor: M. N. Gooseff, D. Van Horn, Z. Sudman, D. M. McKnight, K. A. Welch, W. B. Lyons
Publikováno v: Biogeosciences, Vol 13, Iss 6, Pp 1723-1732 (2016)
Stream channels in the McMurdo Dry Valleys are characteristically wide, incised, and stable. At typical flows, streams occupy a fraction of the oversized channels, providing habitat for algal mats. In January 2012, we discovered substantial channel e

Environmental factors influencing diatom communities in Antarctic cryoconite holes
Autor: L F Stanish, E A Bagshaw, D M McKnight, A G Fountain, M Tranter
Publikováno v: Environmental Research Letters, Vol 8, Iss 4, p 045006 (2013)
Cryoconite holes are ice-bound habitats that can act as refuges for aquatic and terrestrial microorganisms on glacier surfaces. In the McMurdo Dry Valleys of Antarctica, these holes are often capped by an ice lid that prevents the exchange of materia
