Not all altruism is alike, says new study
(Phys.org) -- Not all acts of altruism are alike, says a new study. From bees and wasps that die defending their nests, to elephants that cooperate to care for young, a new mathematical model pinpoints the environmental conditions ...

Evolution in action: Genetic study may answer why we have plenty of fish in the sea
(PhysOrg.com) -- Three-spine sticklebacks aren't as pretty as many aquarium fish, and anglers don't fantasize about hooking one. But biologists treasure these small fish for what they are revealing about the ...

New mathematical model explains how hosts survive parasite attacks
In nature, how do host species survive parasite attacks? This has not been well understood, until now. A new mathematical model shows that when a host and its parasite each have multiple traits governing their ...

Climate change models may underestimate extinctions
Predictions of the loss of animal and plant diversity around the world are common under models of future climate change. But a new study shows that because these climate models don't account for species competition ...

Climate change will show which animals can take the heat
Species' ability to overcome adversity goes beyond Darwin's survival of the fittest. Climate change has made sure of that. In a new study based on simulations examining species and their projected range, researchers ...
