Predator biomass, prey density, and species composition effects on group size in recruit coral reef fishes
Group incidence and size are described for recruit parrotfishes, wrasses, and damselfishes on Hawaiian reefs over 3 years (2006–2008) at sites spanning the archipelago (20–28 N, 155–177 W). Coral-poor and coralrich areas were surveyed at sites with both low (Hawaii Island) and high (Midway Atoll) predator densities, facilitating examination of relations among predator and recruit densities, hab...
متن کاملLinking habitat mosaics and connectivity in a coral reef seascape.
Tropical marine ecosystems are under mounting anthropogenic pressure from overfishing and habitat destruction, leading to declines in their structure and function on a global scale. Although maintaining connectivity among habitats within a seascape is necessary for preserving population resistance and resilience, quantifying movements of individuals within seascapes remains challenging. Traditi...
متن کاملIsolation by resistance across a complex coral reef seascape.
A detailed understanding of the genetic structure of populations and an accurate interpretation of processes driving contemporary patterns of gene flow are fundamental to successful spatial conservation management. The field of seascape genetics seeks to incorporate environmental variables and processes into analyses of population genetic data to improve our understanding of forces driving gene...
متن کاملPlume dispersion on a fringing coral reef system
A field program was implemented on a fringing reef located on Oahu, Hawaii, to investigate the dispersion characteristics of near-bed dye plumes, tracked using an autonomous underwater vehicle (AUV) with an onboard fluorometer. The combination of moored and AUV-based measurements collected synchronously in this study allowed us not only to observe the dispersion characteristics of individual pl...
متن کاملPrediction of Bleaching in Coral Reef Communities Using a Temperature Index(Southern and northern Persian Gulf)
Sea surface temperature is one of the most effective physical parameters that affects the health of coral reefs communities.High frequency of the bleaching phenomenon has extensively occurred in the Persian Gulf in the recent years due to the increase in temperature and increased changes in the sea surface temperature (SST) resulting in great mortality in the coral communities. The aim of this ...
