A key concern with the impacts of overfishing is not exclusive to the methods of extraction. The loss of keystone species can result in potential disruption to trophic structures and alter benthic diversity. Studies variously link the loss of predators (Ruppert et al., 2013) and herbivores (Hughes, 1994) to observable shifts in reef systems.View Ojal Aggarwal - Exploring Trophic Cascades.pdf from SCIENCE N/A at Lambert High School.
