Scared of a ghost: Why Newfoundland caribou migrate despite the disappearance of their historic predator

By Guillaume Bastille-Rousseau 

 

Migration in animals is one of the most spectacular biological phenomena on the planet. Theory predicts that, to evolve, the benefits of migration (in terms of lifetime reproductive success) should outweigh the costs of moving...

Wind dispersal results in a gradient of dispersal limitation and environmental match among discrete aquatic habitats

by Zsófia Horváth, Csaba F. Vad, Robert Ptacnik

 

The Seewinkel region lies on the bordering lowland area between eastern Austria and western Hungary. It has sodic soil and several extremely shallow (<1 m) aquatic habitats, so-called soda pans were formed in...

The introductions of non-native fish species affect the isotopic structure of recipient communities across the globe

by Julien Cucherousset

EDITOR*S CHOICE OCTOBER 2015

Multiple anthropogenic pressures including the widespread introduction of non-native species threaten biodiversity and ecosystem functioning. Non-native species have been reported to induce ecological impacts...

Faster (and exact) phylogenetic diversity computations in R

By Constantinos Tsirogiannis and Brody Sandel

Some species assemblages represent a narrow section of the tree of life, while others include a broader swath. This difference can be quantified with phylogenetic diversity measures, which describe the diversity of an...

Some conservation programs are more successful than others, but we still have little understanding why...

How can different species distribution models be combined?

Favourability models combining different factors in mainland Spain of four representative species: Chioglossa lusitanica, Iberolacerta cyreni, Pterocles orientalis, and Galemys pyrenaicus (favourability ranges from 0 to 1). Five alternative methodological...
