High zooplankton diversity in the extreme environments of the McMurdo Dry Valley lakes, Antarctica
The McMurdo Dry Valley lakes of Antarctica constitute some of the harshest and most isolated freshwater environments on Earth which might be expected to limit the biogeographical expansion of many organisms. Despite this, we found that the biodiversity of rotifer zooplankton is the highest ever reco...
