Study finds pikas may be able to behaviorally buffer against temperature changes
Pikas, those furry little mammals that scurry and skitter between rocks at high elevations, are being studied as a model organism for avoiding temperature stress by a pair of University of Wyoming researchers. Pikas may be ...
Fossils cast doubt on climate-change projections on habitats
Leave it to long-dead short-tailed shrew and flying squirrels to outfox climate-modelers trying to predict future habitats.
Fairy circles apparently not created by termites after all
For several decades scientists have been trying to come up with an explanation for the formation of the enigmatic, vegetation-free circles frequently found in certain African grassland regions. Now researchers have tested ...
Predators predict longevity of birds
(Phys.org) —Ageing inevitably occurs both in humans and in other animals. However, life-span varies widely across species. Researchers of the Max Planck Institute for Ornithology in Seewiesen have now found a possible general ...
Swallows of the western skies
Ushuaia and Fairbanks are cities near the tips of the world.
Study redefines ecological model: Competition among species can cause geographical isolation
In a study that could alter traditional notions in the fields of ecology and evolutionary biology, three City College of New York researchers present results indicating that competition between two species can lead to the ...
New research reveals that emperor penguins are more willing to relocate
A new study led by the University of Minnesota offers new insights on the long-term future of emperor penguins by showing that the penguins may be behaving in ways that allow them to adapt to their changing environment better ...
Private land 'can help save Australia's imperilled wildlife'
Private land can help protect Australia's endangered bird populations as effectively as the nation's best performing conservation reserves, a new study shows.
Oil palm plantations leave ants isolated
Cutting down rainforest to create oil-palm plantations causes canopy-dwelling ant populations to break up into mutually-exclusive territories with very little overlap, according to new research.
Smaller islands host shorter food chains
That smaller islands will typically sustain fewer species than large ones is a widespread pattern in nature. Now a team of researchers shows that smaller area will mean not only fewer species, but also shorter food chains. ...
