Self-recruitment in a coral reef fish population in a marine reserve Marcela Herrera Sarrias Marine protected areas (MPAs) have proliferated in the past decades to protect biodiversity and sustain fisheries. However, most of the MPA networks have been designed without taking into account a critical factor: the larval dispersal patterns of populations within and outside the reserves. The scale and predictability of larval dispersal, however, remain unknown due to the difficulty of measuring… 
Genetic Analysis of Larval Dispersal, Gene Flow, and Connectivity
Establishing the degree to which different populations are connected by larval dispersal is a fundamental goal for larval ecologists interested in understanding the influence of planktonic processes and larval supply on ecological and evolutionary processes within populations.
Population genetic and phylogeographic insights into the phyllosomal odyssey
The combined effects of geography, ocean currents, and biology overcome extremely long pelagic periods and result in variable degrees of genetic connectivity.
Swimming speeds of Mediterranean settlement‐stage fish larvae nuance Hjort's aberrant drift hypothesis
The findings suggest that aberrant drift is unlikely to occur for strong swimming temperate larvae and show that larval behavior should be considered on equal footing with ocean currents when assessing larval fish dispersal.
Scaling of processes shaping the clonal dynamics and genetic mosaic of seagrasses through temporal genetic monitoring
3 years of evolution in the clonal and genetic composition of Zostera marina meadows is quantified, comparing parameters describing clonal architecture and genetic diversity at nine microsatellite markers to suggest the coexistence of a fine grained core of persistent genets originating from an initial seedling recruitment and developing spatial dominance through clonal elongation.

Larval dispersal connects fish populations in a network of marine protected areas
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.
Larval retention and connectivity among populations of corals and reef fishes: history, advances and challenges
A recent dramatic increase in research effort and a growing diversity of approaches to the study of larval retention within (self-recruitment) and dispersal among (connectivity) isolated coral reef populations are highlighted.
Connectivity dominates larval replenishment in a coastal reef fish metapopulation
Comparison of the data with previous studies suggested that variation in dispersal distances is likely to be influenced by the geographical setting and spacing of sub-populations.

Local Replenishment of Coral Reef Fish Populations in a Marine Reserve
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.

Persistence of self-recruitment and patterns of larval connectivity in a marine protected area network
Genetic parentage analysis is used to demonstrate that patterns of self-recruitment of two reef fishes in an MPA in Kimbe Bay, Papua New Guinea, were remarkably consistent over several years, but dispersal from this reserve to two other nodes in a MPA network varied between species and through time.
Connectivity and resilience of coral reef metapopulations in marine protected areas: matching empirical efforts to predictive needs
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.
Kinship analyses identify fish dispersal events on a temperate coastline
It is demonstrated that sibship reconstruction allows direct measurements of dispersal and family structure in marine species while being more easily applied in those species for which the collection of the parental population is difficult or unfeasible.
