It has long been an axiom of environmental science that a diverse ecological community (aka biodiversity) is more resilient and productive because it stabilizes the ecological system as a whole. This should not be confused with a focus on an individual species for which the complex interactions within...

Did Gulf surface bacteria not find Deepwater Horizon oil to be a complete diet?
