BENEFIT-SHARING STATEMENT

Benefits generated: This project is part of a larger research collaboration seeking to understand the biodiversity and evolution of the enigmatic crustacean group Facetotecta. The collaboration was developed with scientists from diverse countries, all of which provided unique samples and are co-authors of the present paper. Our research targets providing molecular resources for understanding y-larva evolution, but the protocols should work for any invertebrate taxon with molting larvae. Our project will therefore benefit the wider community in evolutionary ecology. Our research group is committed to broad, diverse, and inclusive scientific collaborations, evidenced by our team members and samplings originating from diverse countries.
