Change in biomass of Andropogon gerardii due to climate change

Change in biomass of Andropogon gerardii due to climate change

Just accepted in Global Change Biology: our work extending the “species” distribution paradigm (which is so limited) to phenotype!  In short, we found that SDMs predicted widespread decline the prevalence of a dominant prairie plant while PDMs suggest that this decline will be matched by reductions in stature, biomass, and leaf width.  This has been a fun collaboration with Loretta Johnson, Jake Alsdurf, and Mary Knapp, and I’m looking forward to pushing more (climate) envelopes of the possible with them!

A Perfect Storm of Threats

Number of rare plant species threatened by recreation

Number of rare plant species threatened by recreation

Just out: a new analysis by Haydee Hernández-Yáñez and 7 other students at the University of Missouri-Saint Louis and myself on the threats that affect all known rare plants of the US! This is a reprise of the analysis by David Wilcove and colleagues from 1998.  We already got coverage on NPR and Inside Science!

Not appearing in the analysis is the spatial aspect (see image to the right) which we decided to drop near the end because of the article was getting too long.  Still, I’m hoping this will become something else on its own!
