Invasion by mobile aquatic consumers enhances secondary production and increases top-down control of lower trophic levels

Increased biological diversity due to invasion by non-indigenous species (NIS) is a global phenomenon with potential effects on trophic interactions and ecosystem processes in the invaded habitat. We assessed the effects of resource availability and invasion of three non-indigenous invertebrate grazers (two crustaceans and a snail) on secondary production… CONTINUE READING
