Demography of two tunda plants across their North American latitudinal ranges

Duke University & William Morris
All demographic rates were measured for two long-lived, non-clonal tundra plants (Silene acaulis and Polygonum viviparum) in multiple populations from 36 to 69 degrees N latitude, every year since populations were begun from 1995 to 2008 (depending on population) until the present. Soil temperature was also measured over the entire year in all populations since 2008.
