Evolutionary ecology and the conservation of biodiversity.
Studies on evolving interactions among species and the coevolutionary process have suggested that the conservation of biodiversity requires a broad geographic perspective, if the `interaction biodiversity' of the earth is to be conserved with its species diversity. Continued maintenance of the geographic mosaic of specialization, defense and population structure appears to be crucial to the coevolutionary process and the long-term persistence of some interspecific interactions.
