Reservoirs may accelerate the spread of invasive aquatic species, researchers say

Just as disturbance makes a landscape susceptible to invasion by alien plant species, the construction of reservoirs around the globe could be contributing to the accelerating spread of exotic aquatic species, according to a Forum article in the June 2005 issue of BioSc...

Prehistoric decline of freshwater mussels tied to large-scale maize cultivation
