Forest Mortality in Lake Tahoe Basin from 1985-2010: Influences of Forest Type, Stand Density, Topography and Climate
Widespread and synchronous outbreaks of forest mortality during the 1990s and continuing to present day have drastically altered millions of hectares of forestlands from Mexico to Alaska (Bentz 2009). Tree mortality is a complex process with a variety of both exogenous and endogenous factors …

Mapping the Distribution of Barrier Island Slash Pine Woodland and Determining Growth Responses of Pinus elliottii to Hurricane Katrina (2005) on Cat Island, Mississippi
… but was estimated to have the least amount of forest mortality. The purpose of this study was to investigate the distribution of <em>Pinus elliottii </em>on Cat Island Mississippi and evaluate relationships of elevation with mean radial growth rate (mm y ̄ ˡ), stem diameter (cm), and change in …

Population-Level Differences in Pinus monophylla Whole-Plant Seedling Strategies Under Varying Precipitation Pulses
As climate change exacerbates forest mortality, subsequent tree regeneration depends on the presence of functional traits that allow seedlings to survive selective pressures from altered climate regimes. Many widely-distributed plant species exhibit intraspecific trait variation reflecting …

Mortality of native forest vegetation in the Kaimai ranges
Vegetation mortality has been evident in the Kaimai Ranges, North Island, New Zealand for at least 40 years and affects a wide range of species and forest types. The mortality occurs above 550 m altitude and on each prominence has a lower limit which corresponds closely with the predominant cloud …

Effects of Air vs. Air+Soil Heating During a Simulated Heat Wave on White Oak (Quercus alba) and Black Oak (Quercus velutina)
… reductions in Net Primary Productivity and mortality have been reported during heat waves in forested ecosystems. Unfortunately, our understanding of how abrupt heat-stress affects woody species during heat waves lags behind our knowledge of herbaceous species that have been more widely …
