Our study of thermal vegetation focuses on Agrostis rossiae (Ross' Bentgrass) and its cousins, which grow only in thermal areas near Old Faithful.
Our results show that these rare plants are most closely related to similar species that grow in small populations inside the Kronotsky Reserve of Kamchatka, Russian Federation.
Our survey of Yellowstone's geothermal vegetation has illustrated that the park provides a unique opportunity for studying how plants will respond to global climate change in the next century.
We have identified numerous study sites with elevated carbon dioxide concentrations and paired them with control (ambient CO2) sites.
Our study of "trophic cascades" on Yellowstone's northern range seeks to explain why riparian willows have been getting taller for the first time in about 80 years.
