Geographic extent and variation of a coral reef trophic cascade

Geographic extent and variation of a coral reef trophic cascade

Trophic cascades caused by a reduction in predators of sea urchins have been reported in Indian Ocean and Caribbean coral reefs. Previous studies have been constrained by their site‐specific nature and limited spatial replication, which has produced site and species‐specific understanding that c...

Zusammenfassung:Trophic cascades caused by a reduction in predators of sea urchins have been reported in Indian Ocean and Caribbean coral reefs. Previous studies have been constrained by their site‐specific nature and limited spatial replication, which has produced site and species‐specific understanding that can potentially preclude larger community‐organization nuances and generalizations. In this study, we aimed to evaluate the extent and variability of the cascade community in response to fishing across
