Exploring trophic cascades answer key
Direct and indirect biological interactions and trophic cascades suppressing a trophic level in the food web can control entire marine ecosystems. It can, however, be misleading for our understanding and for ecosystem-based management to only investigate the influence of biological interactions and trophic cascades in terms of the biomasses on annual basis, and by comparison of separate ...This calculation is designed available the Interactive Activity set Trophic Cascades at HHMI Biointeractive .

Trophic cascade hypotheses for biological communities, linking predation by upper trophic levels to major features of ecological structure and dynamics at lower trophic levels, are widely subscribed and may influence conservation policy. Few such hypotheses have been evaluated for temporal or spatial generality. Previous studies of sea otter (Enhydra lutris) predation along the outer coast of ...

In the Arctic, the occurrence of trophic cascades seems particularly likely due to the restricted number of interacting species. Spiders are abundant, and their predation of herbivorous ...
