Abstract


WHY DOES THE RED SEA REGION HAVE SO MANY ENDEMIC SPECIES? AN EVOLUTIONARY AND ECOLOGICAL CONNECTIVITY PERSPECTIVE

The Red Sea and seas of the Arabian region represent a unique environment with strong latitudinal gradients in water temperature, salinity, and nutrient load that may act as ecological barriers to larval dispersal and the eventual settlement of marine fauna. We conducted broad-scale surveys of reef organisms employing modern taxonomic (i.e., integrated molecular and morphological studies) and phylogeographic approaches at multiple sites throughout the region. This presentation will explore which groups of reef-associated animals have high levels of endemism in the region. Establishing patterns of biodiversity and biogeography in the Arabian region is one of the first steps towards understanding the underlying drivers of adaptation to the unique Arabian environments. For some taxonomic groups, we have also explored genetic and genomic patterns to help understand how the distributions of these organisms originated, how the distributions are maintained, and the capacity that various population have for adaptation to continued global change. The findings also shed light on ecological and evolutionary connectivity patterns. Future work will integrate local larval dispersal observations, species distributions, genetic data, and large-scale oceanographic models to further understand the role of the Red Sea in the general context of Indo-Pacific biogeography.
