How much science is needed for conservation?

Via Facebook, a colleague shared a link to an essay in Animal Behavior by Tim Caro and Paul Sherman entitled: Eighteen reasons animal behavioralists avoid involvement in conservation (Animal Behavior (2012) 85:305-312).  They exhort behavioral scientists to think more about the conservation value of their research.  I agree with this idea, but that does not mean that I think this is universally appreciated.  At one point, they write: “And all the large NGOs, which have a disproportionate

Are condors more closely related to hawks or to storks?  New research constantly changes our understanding of how birds are related to each other.  At the Field Museum, Shannon Hackett, John Bates, and Dave Willard keep close eyes on avian systematics, the study of evolutionary relationships among birds.  In the past few years, Shannon has collaborated with researchers from other institutions on the Early Bird project to ask big-picture question of how all birds fit on the avian tree of life.

Video: Leo on Bioluminescence

Beyond the reach of sunlight, thousands of feet below the surface of the ocean, some creatures create their own light known as "bioluminescence." Take a trip through the mind of Leo Smith, who asks questions about deep sea fish evolution. Patterns in diversity can offer clues to why fish have evolved so many ways of brightening up the deep sea. Some seem to use light to blend into their surroundings, others to lure prey out of the surroundings, or even to attract mates.
