National drought assessment honored

National drought assessment honored

On Thursday, December 8, Jim Vose, project leader of the U.S. Forest Service Integrated Forest Science accepted the Chief’s Award – one of the highest honors in the Forest Service — in the category of “Sustaining Forests and Grasslands.” Vose accepted as leader of a team that the award honored for “understanding the impacts of drought on the nation’s forests and grasslands: providing a scientific foundation for effective management responses.” read more…

It works: predicting multiple traits from environment

It works: predicting multiple traits from environment

early view in Ecology

Trait analysis aims to understand relationships between traits, species diversity, and the environment. Current methods could benefit from a model-based probabilistic framework that accommodates covariance between traits and quantifies contributions from inherent trait syndromes, species interactions, and responses to the environment… read more

Berdanier in Tree Physiol: Predictive models for sap flux

Berdanier in Tree Physiol: Predictive models for sap flux

Predicting whole-tree water use requires models that accommodate the variation in sap flux between wood types and by depth into the tree. We develop a method for scaling-up flux observations. As an illustrative example, we predict sap flux for a forest in North Carolina, quantifying changes in water use with tree species and size. We include computer software for generating whole-tree flow estimates with other observations in Excel® and the R programming language.
