Capacity building needed to reap the benefits of access to biodiversity collections

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global conservation efforts increasingly depend on digitised natural history collections, yet the benefits of this digital data are not equally shared. We analysed biodiversity specimens and citation data from Montserrat and the Cayman Islands to assess who collected these specimens, how they are used, and by whom.
