Temperature and oxygen are recognised as the main drivers of altitudinal limits of species distributions. However, the two factors are linked, and both decrease with altitude, why their effects are difficult to disentangle. This ...

Freshwater biodiversity is under threat across the globe1, with climate change being a significant contributor2,3. One impact of climate change is the rapid shrinking of glaciers4 , resulting in a reduction in glacial ...

Aim: To test for a possible effect of environmental harshness on large-scale latitudinal and elevational patterns in taxon richness of macrofauna in arctic and alpine glacier-fed streams. Location: Svalbard (79° N), Iceland ...

The downstream pattern in benthic macroinvertebrate assemblages along glacier-fed streams is a result of decreasing glacial influence on environmental conditions. However, meltwater run-off shows temporal variation, reflected ...
