Marine reserves are increasingly important for species that are being forced by climate change to move to a new home, adapt to new conditions or die. Stanford biologist Steve Palumbi compares the relative benefits of large and small protected areas in perpetuating populations. He also has found a coral species that has developed the “skills” [...]

Since the dawn of the biological sciences, humankind has struggled to comprehend the relationships among the major groups of “jointed-legged” animals — the arthropods. Now, a team of researchers, including Dr. Joel Martin and Dr. Regina Wetzer from the Natural History Museum of Los Angeles County (NHM), has finished a completely new analysis of the [...]

The Atlantic blue crab, Callinectes sapidus, long prized as a savory meal at a summer party or seafood restaurant, is a multi-million dollar source of income for those who harvest, process and market the crustacean along the U.S. Atlantic and Gulf coasts. Unfortunately, the blue crab population has been declining in recent years under the [...]

Landing is tricky: hit the ground too fast and you will crash and burn; too slow and you may stall and fall. Bees manage their approach by monitoring the speed of images moving across their eyes. By slowing so that the speed of the looming landing pad’s image on the retina remains constant, bees manage [...]
