Extinct Pleistocene carnivores were diurnal and highly active

open access: yesEcography, EarlyView.
There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...

Water availability and evolutionary similarity shape the global distribution of ferns with chlorophyllous spores

open access: yesEcography, EarlyView.
About 14% of all fern species have chlorophyllous spores, which lack dormancy, have thin walls, and have a shorter viability (only a few days in some species). These spores should have limited dispersal distances and be more susceptible to harsher climatic conditions, raising questions about the evolutionary and ecological significance of this trait ...

Speciation, dispersal and the build‐up of fern diversity in the American tropics

open access: yesEcography, EarlyView.
Understanding how the remarkable biodiversity of the American tropics developed has been a long‐standing question, yet knowledge gaps remain. Previous studies examined the roles of bioregions in shaping diversity patterns but often overlooked speciation, a critical driver of species richness, and insufficiently accounted for temporal changes in ...
