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 ...
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 ...
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 ...
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 ...
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.
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 ...
Protecting the unprotected
(Phys.org) —Scientists at the University of St Andrews have warned that global efforts to protect marine mammals are likely to leave the most endangered species entirely unprotected.
Recovery of Hawaiian green sea turtles still short of historic levels, study suggests
Calls to lift protections for the iconic Hawaiian green sea turtle may be premature, according to a new study led by a Stanford researcher.
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.
Researchers investigate impacts of climate change on rare tropical plants
Research led by the University of York has found that the impacts of climate change on rare plants in tropical mountains will vary considerably from site to site and from species to species.
UK butterfly populations threatened by extreme drought and landscape fragmentation
A new study has found that the sensitivity and recovery of UK butterfly populations to extreme drought is affected by the overall area and degree of fragmentation of key habitat types in the landscape.
Exclusive species found at higher altitudes
Researchers have long postulated that animal and vegetation species living in mountainous areas of high altitude are isolated, and thus much more exclusive. A new Spanish-German study substantiates this long-held ...
