title: Data from: A multispecies approach reveals hot-spots and cold-spots of diversity and connectivity in invertebrate species with contrasting dispersal modes

description: Genetic diversity is crucial for species’ maintenance and persistence, yet
 is often overlooked in conservation studies. Species diversity is more
 often reported due to practical constraints, but it is unknown if these
 measures of diversity are correlated. In marine invertebrates, adults are
 often sessile or sedentary and populations exchange genes via dispersal of
 gametes and larvae. Species with a larval period are expected to have more
 connected populations than those without larval dispersal. We assessed the
 relationship between measures of species and genetic diversity, and
 between dispersal ability and connectivity. We compiled data on genetic
 patterns and life history traits in nine species across five phyla.
 Sampling sites spanned 600 km in the northwest Mediterranean Sea and
 focused on a 50 km area near Marseilles, France. Comparative population
 genetic approaches yielded three main results. (1) Species without larvae
 showed higher levels of genetic structure than species with free-living
 larvae but the role of larval type (lecithotrophic or planktotrophic) was
 negligible. (2) A narrow area around Marseilles, subject to offshore
 advection, limited genetic connectivity in most species. (3) We identified
 sites with significant positive contributions to overall genetic diversity
 across all species, corresponding with areas near low human population
 densities. In contrast, high levels of human activity corresponded with a
 negative contribution to overall genetic diversity. Genetic diversity
 within species was positively and significantly linearly related with
 local species diversity. Our study suggests that local contribution to
 overall genetic diversity should be taken into account for future
 conservation strategies.
