Species diversity in Friesea (Neanuridae) reveals similar biogeographic patterns among Antarctic Collembola
Abstract The pan‐Antarctic distributions of several collembolan species have been supported by morphology for over 120 years. However, for most species where molecular data are available, these are now known to belong instead to several species, and most classified as short‐range endemics. One such...

Abstract The pan‐Antarctic distributions of several collembolan species have been supported by morphology for over 120 years.
