In many cases it is the colour of the prey that helps predatory birds to detect, pursue and capture them. In a new study, biologists at Lund University in Sweden show that the Harris's hawk has the best colour vision of all animals investigated to date -- and in certain situations, even better than humans....

Growing beaver populations have created a large number of new habitats along rivers and ponds. Beaver dams raise the water level, enabling the dissolution of the organic carbon from the soil. From beaver ponds, carbon is released to the atmosphere. Part of the carbon settles down on the bottom, ending up used by plants or...

Goats can differentiate between human facial expressions and prefer to interact with happy people, according to a new study led by scientists at Queen Mary University of London.

In an article published at journal Acta Oecologica, Brazilian biologist Luciano Palmieri Rocha has proposed a new phase of the development cycle of fig trees (Ficus carica) and their specific pollinators, fig wasps from the species Blastophaga psenes - one of the most studied cases when analyzing the evolution of mutualism.

The effects of island remoteness from the mainland on the number of species found on islands differs strongly for non-native compared to native species. Numbers of native species on islands decrease with greater remoteness, while numbers of non-native species increase. This surprising finding has been uncovered by an international research team led by Dietmar Moser,...

The evolutionary context of the eggplant was until recently very poorly known. Historical documents and genetic data have shown that the eggplant was first domesticated in Asia, but most of its wild relatives are from Africa. Researchers from the Natural History Museums of London (NHM) and Finland (University of Helsinki) managed to obtain the first...
