TL;DR: It is shown that, across multiple tree species, loss of xylem conductivity above 60% is associated with mortality, while carbon starvation is not universal, indicating that evidence supporting carbon starvation was not universal.
Journal ArticleDOI

TL;DR: A global tree mortality map is updated and a roadmap to a more holistic understanding of forest mortality across scales is presented to achieve scientific understanding for realistic predictions of drought-induced tree mortality.
Journal ArticleDOI
Direct and indirect ecosystem consequences of an invasive pest on forests dominated by eastern hemlock
TL;DR: In this article, the authors compared the magnitude and trajectory of vegetation and ecosystem function dynamics associated with the direct impact of hemlock woolly adelgid (Adelges tsugae Annand; HWA) infestation vs. the indirect consequences of HWA-induced damage in the form of salvage and pre-emptive logging.
Journal ArticleDOI
Modeling when, where, and how to manage a forest epidemic, motivated by sudden oak death in California.
Nicholas James Cunniffe,Richard Cobb,Ross K. Meentemeyer,David M. Rizzo,Christopher A. Gilligan +4 more
TL;DR: A stochastic spatially explicit model parameterized using data on the spread of P. ramorum is used in California to investigate whether and how the epidemic can be controlled and finds that a dynamic strategy treating sites on the epidemic wave front leads to optimal performance.
Journal ArticleDOI
Hemlock Woolly Adelgid in New England Forests: Canopy Impacts Transforming Ecosystem Processes and Landscapes
TL;DR: In this article, the authors examined the relationship between diverse effects for the hemlock woolly adelgid (HWA, Adelges tsugae Annand) in New England forests by studying its impacts on local canopy processes in stands differing in infestation levels and linking these impacts to shifts in canopy nutrient cycling and stand and landscape effects.
