White and wonderful? Microplastics prevail in snow from the Alps to the Arctic

open access: yesScience Advances, 2019
We detect microplastics in European and Arctic snow, highlighting the importance of atmospheric transport as a pathway. Microplastics (MPs) are ubiquitous, and considerable quantities prevail even in the Arctic; however, there are large knowledge gaps ...

Interannual climate variability improves niche estimates for ectothermic but not endothermic species

open access: yesScientific Reports, 2023
Climate is an important limiting factor of species’ niches and it is therefore regularly included in ecological applications such as species distribution models (SDMs).
