Behavioral Ecology and Conservation Biology by Tim Caro

By Tim Caro

This quantity is the 1st try and hyperlink those disciplines officially. right here best researchers discover present themes in conservation biology and talk about how behavioral ecology can give a contribution to a better figuring out of conservation difficulties and conservation intervention courses. In every one bankruptcy, the authors establish a conservation factor, overview the methods it's been addressed, evaluation behavioral ecological information on the topic of it, together with their very own, overview the strengths and weaknesses of the behavioral ecological technique, and recommend particular conservation ideas. The chapters juxtapose assorted reviews on a large choice of taxonomic teams. a couple of universal topics emerge, together with the ways that animal mating structures have an effect on inhabitants endurance, the jobs of dispersal and inbreeding avoidance for subject matters corresponding to reserve layout and powerful inhabitants measurement, the most important function of people in conservation concerns, and the significance of baseline information for conservation tracking and modeling makes an attempt. every one bankruptcy sheds new gentle on conservation difficulties, generates leading edge avenues of interdisciplinary learn, and indicates how conservation-minded behavioral ecologists can observe their services to a few of crucial questions we are facing this day.
