Aim We assess biogeographical patterns, population structure and the range of species in
the pulmonate genus Siphonaria across the sub‐Antarctic. We hypothesized that locally …

Antarctica is isolated, surrounded by the Southern Ocean and has experienced extreme
environmental conditions for millions of years, including during recent Pleistocene glacial …

The patterns in and the processes underlying the distribution of invertebrates among
Southern Ocean islands and across vegetation types on these islands are reasonably well …

Aim We examined the genetic structure among populations and regions for the springtails
Cryptopygus antarcticus antarcticus and Gomphiocephalus hodgsoni (Collembola) to …

The evolutionary history of Antarctic organisms is becoming increasingly important to
understand and manage population trajectories under rapid environmental change. The …

Abstract Throughout the Southern Hemisphere many terrestrial taxa have circum-Antarctic
distributions. This pattern is generally attributed to ongoing dispersal (by wind, water, or …

We examine the effects of isolation over both ancient and contemporary timescales on
evolutionary diversification and speciation patterns of springtail species in circum-Antarctica …

Since its introduction, the genus Philine has epitomized numerous mollusc snails with strong
morphological convergence. Recently, a molecular analysis including a wide taxon …

Quaternary glaciations in A ntarctica drastically modified geographical ranges and
population sizes of marine benthic invertebrates and thus affected the amount and …

Abstract Aim The Antarctic Circumpolar Current imparts significant structure to the Southern
Ocean biota. The Antarctic Polar Front is a major barrier to dispersal, with separate species …
