Nutrient supply from fishes facilitates macroalgae and suppresses corals in a Caribbean coral reef ecosystem.
On coral reefs, fishes can facilitate coral growth via nutrient excretion; however, as coral abundance declines, these nutrients may help facilitate increases in macroalgae. By combining surveys of reef communities with bioenergetics modeling, we showed that fish excretion supplied 25 times more nitrogen to forereefs in the Florida Keys, USA, than all other biotic and abiotic sources combined. ...
متن کاملAge-Related Shifts in Bacterial Diversity in a Reef Coral.
This study investigated the relationship between microbial communities in differently sized colonies of the massive coral Coelastrea aspera at Phuket, Thailand where colony size could be used as a proxy for age. Results indicated significant differences between the bacterial diversity (ANOSIM, R = 0.76, p = 0.001) of differently sized colonies from the same intertidal reef habitat. Juvenile and...
متن کاملEcosystem-based Management of Coral Reef Fisheries
Issue 1: MPA benefits to fisheries It is crucial to avoid ‘overselling’ MPAs on the basis that increased catches due to spillover and enhanced recruitment from spawning in the MPA will more than make up for lost fishing grounds, increased effort and higher costs of fishers displaced from the MPA. To date, this assumption has never been proven; and spillover is generally measured as movement of ...
متن کاملCoral reef baselines: how much macroalgae is natural?
Identifying the baseline or natural state of an ecosystem is a critical step in effective conservation and restoration. Like most marine ecosystems, coral reefs are being degraded by human activities: corals and fish have declined in abundance and seaweeds, or macroalgae, have become more prevalent. The challenge for resource managers is to reverse these trends, but by how much? Based on survey...
متن کاملPredation and associational refuge drive ontogenetic niche shifts in an arctiid caterpillar.
Despite the ubiquity of ontogenetic niche shifts, their drivers and consequences are poorly understood. Different nutritional requirements and stage-specific physiological limitations have often been offered as explanations for these life history features, but emerging work has demonstrated that top-down factors may also be important. We studied the roles of predation and associational refuge i...
