| Title | Tracking the ice: Subterranean harvestmen distribution matches ancient glacier margins |
| Abstract | Biogeographic studies often underline the role of glacial dynamism during Pleistocene (1.806-0.011 Mya) in shaping the distribution of subterranean species. Accordingly, it is presumed that present-day distribution of most specialized cold-adapted (cryophilic) cave-dwelling species should bear the signatures of past climatic events. To test this idea, we modelled the distribution of specialized cold-adapted subterranean alpine harvestmen (Arachnida: Opiliones: Ischyropsalididae: Ischyropsalis). We found that the distance from the glacier margins during Last Glacial Maximum (LGM; about 22,000 years ago) was the most important predictor of their present-day distribution. In particular, the peak in the probability of occurrence of alpine subterranean Ischyropsalis was found to be in close proximity to the LGM glacier, with a sharp drop at a distance of 30 km from the ice margin. In light of the role played by past climatic events in determining the species current range, we briefly discuss their biogeographic history and the role played by glacial refugia dynamics in determining the current distribution of these species. We argue that low dispersal harvestmen such as our model species can be used as biological indicators for tracking past glaciations and other similar biogeographic events. |
