Many studies have indicated the negative effects of high fish stocks on the diversity of macroinvertebrates. Nevertheless, the
effect of fish predation on invertebrate communities could be strongly influenced by the behavior of individual species as well as other factors, such as the structural complexity of aquatic vegetation. Consequently, we aimed to analyze the habitat selection behavior and the effects of environmental-trait interactions on the responses of amphibians, odonates, aquatic true bugs, and diving beetles that are directly or indirectly related to pond management.
No congruence between habitat specialists and generalists was observed, but a similar response to fish and vegetation structure defined both semiaquatic and aquatic organisms. Moreover, each monitored group reflected very different variables. Odonates were sensitive to variables reflecting the quality of the aquatic environment and the overall landscape structure, and accurately reflected differences in the management intensity of ponds. Our results highlight the significance of habitat selectivity for structuring freshwater ecosystems. However, fish farming management is a selective mechanism that operates with such intensity that there is no morphological or phenological variability among species.
