- He was the first to describe a case of co-evolution - between butterflies and plants - and how it may contrive to generate biological diversity MADRID, Feb. 4, 2014 /PRNewswire/ -- The sixth annual BBVA Foundation Frontiers of Knowledge Award in the Ecology and Conservation Biology category goes to entomologist Paul Ehrlich, Professor of Biology at Stanford University (United States), for having "contributed key conceptual advances in the science of ecology and conservation...

New Model Accurately Describes Migratory Animals’ Extinction Risk
2011-11-17 04:14:41

Predicting the risk of extinction is a complicated task, especially for species that migrate between breeding and wintering sites. Researchers at the University of Georgia and Tulane University have developed a mathematical model that may make such predictions more accurate. Their work appears in the early online edition of the Royal Society journal Biology Letters. "The concern is that for a lot of species, we don't know very much about their wintering grounds," said Richard Hall,...

The song of passerine birds is a conspicuous and exaggerated display shaped by sexual selection in the context of male-male competition or mate attraction. At the level of the individual, song is considered an indicator of male "Ëœquality'. Paola Laiolo and colleagues at the Spanish Council of Research (CSIC) studied the metapopulation system of the Dupont's lark in north-eastern Spain and found an association between individual song diversity and the viability of the population as...

In their article in the July 2005 issue of The American Naturalist, Yssa D. DeWoody, Zhilan Feng, and Robert K. Swihart (Purdue University) model species' occupancy within a patchy dynamic landscape. They derive deterministic persistence thresholds which depend jointly upon the spatial and temporal structure of the landscape, reinforcing the importance of spatio-temporal connectivity. This model has the potential to predict various consequences of different land-use strategies and thus serve...
