Microhabitats, macro-differences: a survey of temperature records in Victoria Land terrestrial and freshwater environments
Abstract The temperature experienced by micro-invertebrates in extreme environments (such as those of Antarctica) is a pivotal parameter regarding these animals' ecology and physiology. However, at present, detailed knowledge of microhabitat physical conditions in Antarctica is limited, as well...
