Extinction rates are expected to increase during the Anthropocene. Current extinction rates of plants and many animals remain unknown. This study represents the first effort to quantify extinctions among the vascular flora of North America north of...

The format of this edited volume offers each of the three communities (natural history museums, botanical gardens, zoological gardens) the opportunity to present their cutting-edge research and communications outreach activities. In addition, this...

Maintaining a living plant collection is the most common method of ex situ conservation for plant
species that cannot be seed banked i.e. “exceptional” species. Viability of living collections, and their value for future conservation efforts,...

Ash tree species in North America are under mortal threat from the Emerald Ash Borer (EAB), now in 35 states and five Canadian provinces. There are ongoing efforts to conserve this native tree species by producing genetically diverse, resistant...
