متن کاملSynergistic effects of reserves and connectivity on ecological resilience
1. In light of the global extent and cascading effect of our impact on the environment, we design and manage reserves to restore biodiversity and the functioning of ecosystems. Mobile organisms link important processes across ecosystems, however, their roles in providing these services are often overlooked and we need to know how they influence ecosystem functions in reserves. Herbivorous fish ...
متن کاملPredation risk, competition, and territorial damselfishes as drivers of herbivore foraging on Caribbean coral reefs
Food availability, competition, habitat complexity, and territorial damselfish shape foraging decisions of herbivorous coral reef fishes. However, relatively little is known about how predators affect herbivore diet selection. We examined diets of 2 common reef herbivores, Sparisoma aurofrenatum and Acanthurus coeruleus, in the Florida Keys, across sites of varying predator biomass. We used sta...
متن کاملPredation Risk, Resource Quality, and Reef Structural Complexity Shape Territoriality in a Coral Reef Herbivore
For many species securing territories is important for feeding and reproduction. Factors such as competition, habitat availability, and male characteristics can influence an individual's ability to establish and maintain a territory. The risk of predation can have an important influence on feeding and reproduction; however, few have studied its effect on territoriality. We investigated territor...
