Article Synopsis
- Understanding the environmental factors affecting genome divergence in marine species, like the edible cockle, is essential for sustainable fisheries management and conservation efforts.
- A population genomics study examined over 9,000 SNPs in 536 cockles from 14 locations in the Northeast Atlantic, revealing significant genetic differentiation and environmental influences such as sea temperature and salinity.
- The analysis identified two main genetic groups and finer subdivisions related to larval dispersal patterns, providing crucial insights for developing conservation strategies and managing cockle populations.
Population dynamics of marine species that are sessile as adults are driven by oceanographic dispersal of larvae from spawning to nursery grounds. This is mediated by life-history traits such as the timing and frequency of spawning, larval behaviour and duration, and settlement success. Here, we use 1725 single nucleotide polymorphisms (SNPs) to study the fine-scale spatial genetic structure in the commercially important cockle species and compare it to environmental variables and current-mediated larval dispersal within a modelling framework.
