Larval dispersal and marine population connectivity.
Connectivity, or the exchange of individuals among marine populations, is a central topic in marine ecology. For most benthic marine species with complex life cycles, this exchange occurs primarily during the pelagic larval stage. The small size of larvae coupled with the vast and complex fluid environment they occupy hamper our ability to quantify dispersal and connectivity. Evidence from dire...
متن کاملOpen and closed seascapes: where does habitat patchiness create populations with high fractions of self-recruitment?
Which populations are replenished primarily by immigrants (open) and which by local production (closed) remains an important question for management with implications for response to exploitation, protection, and disturbance. However, we lack methods for predicting population openness. Here, we develop a model for openness and show that considering habitat isolation explains the existence of su...
متن کاملSharp genetic breaks among populations of Haptosquilla pulchella (Stomatopoda) indicate limits to larval transport: patterns, causes, and consequences.
To help stem the precipitous decline of coral reef ecosystems world-wide, conservation efforts are focused on establishing interconnected reserve networks to protect threatened populations. Because many coral reef organisms have a planktonic or pelagic larval dispersal phase, it is critical to understand the patterns of ecological connectivity between reserve populations that result from larval...
متن کاملConnectivity of the Habitat-Forming Kelp, Ecklonia radiata within and among Estuaries and Open Coast
With marine protected areas being established worldwide there is a pressing need to understand how the physical setting in which these areas are placed influences patterns of dispersal and connectivity of important marine organisms. This is particularly critical for dynamic and complex nearshore marine environments where patterns of genetic structure of organisms are often chaotic and uncoupled...
متن کاملLocal Retention of Production in Marine Populations: Evidence, Mechanisms, and Consequences
A major unanswered question in marine ecology is the degree of connectedness between local populations. Put another way, what proportion of young arriving into a local population are products of local production? What is the source of recruits for any local population, and where do the young produced in a local population go? The answers to these questions are unknown for most widespread specie...
