Surviving out in the cold: Antarctic endemic invertebrates and their refugia
Abstract Aim To identify Antarctic palaeoendemic taxa and their probable glacial refugia from regional groups of endemic species records. Location Antarctica. Methods We compiled a list of Antarctic non‐marine invertebrates from published literature, and then deleted all records relating to non‐ende...
