Patterns of population genetics and connectivity of squat lobsters in vulnerable marine ecosystems

Squat lobsters are highly diversified and widespread decapods. They may be associated with habitat-forming benthic species (e.g. corals). In New Zealand’s EEZ, three Munida species (M. isos, M. endeavourae and M. gracilis) are abundant and widely distributed, sometimes in association with coral (VME) formations. My research will focus on the population genetics and connectivity of the three Munida species from within and outside the New Zealand EEZ, which will help provide information for the effective management of the deep-sea and its VMEs.
