Fifteen years ago, Steven Phillips, a computer science researcher at AT&T Labs from South Africa, walked a few blocks from his apartment in New York City to the American Museum of Natural...
In simulations comparing a population spread in a spatially homogenous (left) versus patchy (right) landscapes, variation in the Allee effect induces variation in spread patterns and increases the overall rate of spread.

The sigmodontine rodent genus Eligmodontia includes highly specialized desert-dwellers in the Southern Cone of South America. Species of gerbil mice have inflated auditory bullae, and are also capable of bipedal jumping and elevated urine concentration. Photo by...
Underwater pictures taken on the wall of the new island at Potter Cove. Both pictures were taken between 10 and 15 m depth where a high abundances of filters feeders such as ascidians and sponges were found. Note the aluminum ruler (10 cm long) that was attached to the...
