Coral Reef Fish Larvae Settle Close to Home
Local Replenishment of Coral Reef Fish Populations in a Marine Reserve
TLDR
If natal homing of larvae is a common life-history strategy, the appropriate spatial scales for the management and conservation of coral reefs are likely to be much smaller than previously assumed.
Critical science gaps impede use of no-take fishery reserves.
Marine reserves: size and age do matter.
TLDR
Using 58 datasets from 19 European marine reserves, it is shown that reserve size and age do matter: Increasing the size of the no-take zone increases the density of commercial fishes within the reserve compared with outside; whereas thesize of the buffer zone has the opposite effect.
GENE FLOW AND LARVAL DURATION IN SEVEN SPECIES OF FISH FROM THE GREAT BARRIER REEF
TLDR
Calculations of gene flow between geographic regions predict panmixis for species with larval durations exceeding 1 mo, which suggests that fish larvae may use their greater mobility to retard, rather than enhance, dispersal due to hydrodynamic advection.
Larval dispersal connects fish populations in a network of marine protected areas
TLDR
DNA parentage analysis is used to provide the first direct estimates of connectivity of a marine fish, the orange clownfish (Amphiprion percula), in a proposed network of marine reserves in Kimbe Bay, Papua New Guinea, suggesting that MPA networks can function to sustain resident populations both by local replenishment and through larval dispersal from other reserves.
Predator Crown-of-Thorns Starfish (Acanthaster planci) Outbreak, Mass Mortality of Corals, and Cascading Effects on Reef Fish and Benthic Communities
TLDR
This study elucidates the processes involved in an Acanthaster outbreak and shows how sessile benthic communities and resident coral-feeding fish assemblages were subsequently affected by the decline of corals.
Connectivity and resilience of coral reef metapopulations in marine protected areas: matching empirical efforts to predictive needs
TLDR
To make rapid progress in understanding the scales and patterns of connectivity, greater communication between empiricists and population modelers will be need to track and assimilate evolving empirical results.
Transgenerational marking of embryonic otoliths in marine fishes using barium stable isotopes
We describe a new technique for transgenerational marking of embryonic otoliths that promises significant advancements in the study of larval dispersal and population connectivity in marine fishes.
