Combined effects of climate change and competition on tree survival and growth of Juglans nigra natural populations

by Joshua Gershey

Natural tree populations spend many generations adapting to their home climate.  Climate change is predicted to exceed natural rates of population adaptation causing maladapted populations.  Inter-tree competition may compound this, reducing growth and species population survival.  This study evaluates 36 natural populations of Juglans nigra distributed across the native range in a common garden experiment.  Generalized mixed linear models were developed; predicting tree growth and survival as a function of additive and interactive climate-competition effects.
