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.
