Predator-prey body size relationship in temporary wetlands: effect of predatory insects on prey size spectra and survival
The effect of predatory insects on prey size distribution was investigated in two temporary Andean wetlands, located in northwest of Patagonia Argentina. The wetlands studied showed heterogeneous prey size structure and the insects impacted on survival of different prey size and stages. However the size-limited predators investigated here, seems no influence on the body size structure of the prey, other variables could be more important in the size structure of these aquatic ecosystems.
