Coral range expansion is accompanied by reduced sybiont genotype diversity

17 May, 2017

In our latest study by Grupstra et al. we investigate how coral range expansion affects genotypic diversity of their algal sybionts. We find that in the investigated species (O. patagonica​) range expansion may come at the cost of reducing symbiont diversity, possibly due to limited symbiont dispersal. This reduction in symbiont diversity may have important implications for the resilience of corals in times of rapid environmentla change. Rad the full study published in Coral Reefs!
