Dispersal and Connectivity of Early Life Stages of Marine Organisms

Session ID#: 254573

Session Description:
The vast majority of marine animals exhibit a biphasic life cycle, with an initial larval phase that is responsible for setting the upper limits of species dispersal and population connectivity. These early stages are often life history bottlenecks, but their study requires interdisciplinary efforts, because the process of dispersal is shaped by both biological factors (e.g., adult reproductive phenology, larval behavior, mortality) and physical transport over both small and large spatial scales. Connectivity is further shaped by post-settlement processes. Changes in recruitment can impact the size and structure of marine populations and communities, with implications for conservation, fisheries sustainability, spread of invasive species, and biogeographic patterns of biodiversity. 

The aim of this session is to bring together researchers investigating early life history dynamics and/or dispersal across disciplines, methods, study systems, and taxa – from estuaries to deep sea ecosystems. While our language is focused on the larval stages of benthic invertebrates and fishes, we welcome studies focused on dispersal processes in other systems (e.g., other zooplankton, marine plants and algae, pollutants and microplastics), as well as those that focus on up- and down-stream processes (e.g., reproduction, development, recruitment). We encourage submissions from laboratory, field, modeling, and molecular studies.
