MAPPING HOTSPOTS TO HELP MIGRANTS.

Microscope WIDE-OPEN SPECTRUM After analyzing vision research on nearly 450 species, University of Arkansas biologists report in the Proceedings of the Royal Society B that wildlife adapted to open habitats (such as prairie dogs, left) see a wider range of colors than forest animals. Unfortunately, these "small pockets of deciduous forest are often neglected in conservation planning", says Princeton ecologist and lead author Fengyi Guo, who hopes the new migration stopover map will help to change that. The map, published in the Proceedings of the National Academy of Sciences, "gives us a powerful new tool for identifying the key habitats these birds are using during their epic migrations", says Princeton ecologist and co-author David Wilcove.
