Human activity selectively impacts the ecosystem roles of parrotfishes on coral reefs.
Around the globe, coral reefs and other marine ecosystems are increasingly overfished. Conventionally, studies of fishing impacts have focused on the population size and dynamics of targeted stocks rather than the broader ecosystem-wide effects of harvesting. Using parrotfishes as an example, we show how coral reef fish populations respond to escalating fishing pressure across the Indian and Pa...
متن کاملHybridisation on coral reefs and the conservation of evolutionary novelty
Hybridisation was traditionally considered rare on coral reefs. However, a rapid increase in hybrid studies over the last 20 years has revealed that hybridisation on coral reefs is common and widespread. In this review, we summarise the growing body of evidence arising from studies on stony corals and reef fishes to verify the occurrence of hybridization, and we examine the influence hybridisat...
متن کاملSwimming speeds of larval coral reef fishes: impacts on self-recruitment and dispersal
The dispersal of larvae during their time in the pelagic environment is critically important to our understanding of marine populations. Recent publications have highlighted the potential importance of larval behaviour in influencing dispersal patterns of larval reef fishes. However, it has not been clearly established if their abilities are of a magnitude comparable to the potential effects of...
متن کاملEcological Consequences of Sediment on High-Energy Coral Reefs
Sediments are widely accepted as a threat to coral reefs but our understanding of their ecological impacts is limited. Evidence has suggested that benthic sediments bound within the epilithic algal matrix (EAM) suppress reef fish herbivory, a key ecological process maintaining reef resilience. An experimental combination of caging and sediment addition treatments were used to investigate the ef...
متن کاملSpatial variation of symbiotic Dinoflagellates on coral reefs of the northern Persian Gulf
Density, mitotic index, Chlorophyll-a content and cell size of symbiotic dinoflagellates of dominant reef-building corals were measured at two different depths in Kish Island and from one depth of Larak Island in the Persian Gulf. The higher densities of symbionts were found in shallow waters of Kish Island. However, ANOVA analyses of the mitotic index yielded mixed results. The cell sizes of s...
