Linking biodiversity and geodiversity: Arctic-nesting birds select refuges generated by permafrost degradation

The physical characteristics of islets selected by Arctic-nesting birds and the geomorphological processes generating islets available in the landscape are identified.

Expert elicitation of state shifts and divergent sensitivities to climate warming across northern ecosystems

Northern regions are warming faster than the rest of the globe. It is difficult to predict ecosystem responses to warming because the thermal sensitivity of their biophysical components varies. Here,…

Experimental and field evidence indicate that islet-nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

It is found that islets act as partial prey refuges, with higher nest survival rates on islets than on pond and lake shores, and the interplay between microhabitat selection and predator-multi-prey dynamics in the arctic tundra is highlighted.

Linking geomorphological processes and wildlife microhabitat selection: nesting birds select refuges generated by permafrost degradation in the Arctic

It was found that ice-wedge polygon degradation generated the majority of islets found in the landscape, and those islets were on average farther from the shore and surrounded by deeper water than those generated by other processes.
