Abstract excerpt

Understanding how gene-flow and selection interact across environmental gradients is essential for assessing population resilience and evaluating the deep-refugia potential of mesophotic habitats under rapid climate change. In the context of depth, genetic connectivity patterns have been documented for broadcast-spawning species, but that of brooding marine invertebrates remains largely unexplored, leaving the...
