Boreas, EarlyView.This study contains a comprehensive regional analysis of the orientations of tunnel valleys, faults and salt structures in the North German Basin, aiming to identify correlations that might indicate a structural control on tunnel‐valley formation. A structural control on tunnel‐valley formation has been repeatedly postulated and correlations have been ...

Evaluating migration hypotheses for the extinct Glyptotherium using ecological niche modeling
Ecography, EarlyView.The formation of the Isthmus of Panama allowed for migrations between the once separated continents of North and South America. This led to one of the greatest documented interchanges of biota in Earth history, wherein an array of species across many groups migrated between the continents.

Ecography, EarlyView.The biogeographic affinity of a lineage leaves imprint on its niche, and influences its distribution under biotic interchange between landmasses. Since the beginning of the Quaternary, North America (a remnant of Laurasia) and South America (a remnant of Gondwana) have been united, and triggered the Great American Biotic Interchange.

Ecography, EarlyView.Communities of insects around the world consist of unique sets of species that have evolved under different historical processes of assembly and lineage diversification. Whole‐community phylogenetics can partition the shared and uniquely derived evolutionary history across sites.
