STUDY OF SYNANTHROPIC PLANTS OF THE SOUTH URAL

International Journal of GEOMATE, 2017
The present study aimed to assess the long-term dynamics of the synanthropic vegetation of the road and path network of the Ilmen State Reserve. The analysis of the synanthropic species spread among coenofloras of the elements of the road and path network revealed an increasing synanthropization index in the gradient of the stress factor for all forest

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

PLANTS, 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 ...
