Dataset Results
The purpose of this experiment, performed as part of the McMurdo Dry Valleys Long Term Ecological Research (MCM LTER) program, was to investigate the impact of lake level rise and moat expansion on microbial community diversity and function in the East Lobe of Lake Bonney, located in Taylor Valley, Antarctica. The “tLICE” experiment tested the following MCM5 Hypotheses: H3-Disturbance increases connectivity and accelerates shifts towards homogeneity, and H4-Decreased heterogeneity reduces community resistance and resilience.

Populations of Plectus murrayi, a mesophilic nematode, have been increasing in the McMurdo Dry Valleys, Antarctica over the past three decades. In contrast, most other Antarctic nematode species, including Scottnema lindsayae, have experienced constant population declines over the same time period due to climate change related increases in summer temperatures and wetting occurrences. To determine why P.
