NSF

Awesome news! We were just informed that the National Science Foundation will fund our proposal to use pollen, genetic, and distributional data to estimate the spatial dynamics of how trees migrated poleward after the last glacial maximum.  This is a collaborative project with Sean Hoban (Morton Arboretum), Andria Dawson (Mount Royal University), John Robinson (Michigan State University), and Allan Strand (College of Charleston). We will be hiring two postdocs over the 3 years of the grant, so please contact me if interested.

 

Phenotypic distribution modeling

Tuesday, November 14th, 2017

Our latest paper in Global Change Biology on modeling intraspecific phenotypic variation has gotten great press!  Combined, the news outlets covering our research reach ~78 million people and included The San Francisco Chronicle, The Seattle Times, US News and World Report, The Topeka Capital Journal, The Manhattan Mercury, and numerous other regional newspapers, radio stations (e.g., KWMU 90.7), TV stations (e.g., KWCH12), and science news websites (e.g., Science News Online)!

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!
