Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...
