I am particularly interested in macroevolutionary patterns and characters that diagnose large clades of ferns and lycophytes. My field work is centered in Mexico, Colombia, and Papua New Guinea. I am based in the Pringle Herbarium (VT) at the University of Vermont. If you have any ferns that you want identified, please send them to me!
Equisetum has been around since the Jurrasic. What has contributed to this longevity? Satjarak et al. found evidence for eukaryotic microorganisms associated with Atacama Desert populations of Giant Equisetum, which may aid in its survival https://doi.org/10.1640/0002-8444-111.2.86
