Adaptations to low moisture availability are arguably as important as cold resistance for polar terrestrial invertebrates, especially because water, in the form of ice, is biologically inaccessible for much of the year. Desiccation responses under ecologically realistic soil humidity conditions--those close to the wilting points of plants [98.9% relative humidity (RH)]--have not previously been examined in polar insect species. In the current study we show that, when desiccated at 98.2% RH… CONTINUE READING
