... to resources necessary for its survival. Although coexistence
is often attributed to interspecific differences in morphology, direct evidence is relatively rare. Dabbling ducks, which include the ubiquitous mallard, are a good example. Dabbling ducks are primarily filter-feeders. They use lamellae, which are co...
Human behavior changes the number of strains of infectious diseases
...t is all-important. The researchers found that the coexistence
of multiple infectious disease strains result from monogamous populations. "When people are serially monogamous (that is, interactions take place one at a time), groups with different behavior favor strains with different properties," explain the a...
