Natural history collections, such as herbaria, are well positioned for the analysis of global change and the resulting impacts on regional biota. In this context, the digitized herbarium specimen data from the Texas Oklahoma Regional Consortium of Herbaria provide the capacity for addressing major hypotheses in the region concerning patterns of species richness and phylogenetic diversity, vegetation responses to climate change, and species distribution models based on substrate versus climatic data. This seminar will focus on Texas digitization and discoveries, showcasing the rich legacy of plant data in our state.
