Historical biogeography of the Gondwanan freshwater genus Boeckella (Crustacea): timing and modes of speciation in the Southern Hemisphere
Aim We investigated evolutionary relationships and biogeographical patterns within the genus Boeckella to evaluate (1) whether its current widespread distribution in the Southern Hemisphere is due to recent long-distance dispersal or long-term diversification; and (2) the age and origin of sub-Antar...
