A global overview of drought and heat-induced tree mortality reveals emerging climate change risks for forests
Greenhouse gas emissions have significantly altered global climate, and will continue to do so in the future. Increases in the frequency, duration, and/or severity of drought and heat stressExpand
Mechanisms of plant survival and mortality during drought: why do some plants survive while others succumb to drought?
TLDR
A hydraulically based theory considering carbon balance and insect resistance that allowed development and examination of hypotheses regarding survival and mortality was developed, and incorporating this hydraulic framework may be effective for modeling plant survival andortality under future climate conditions. Expand
Regional vegetation die-off in response to global-change-type drought.
TLDR
The results quantify a trigger leading to rapid, drought-induced die-off of overstory woody plants at subcontinental scale and highlight the potential for such die-offs to be more severe and extensive for future global-change-type drought under warmer conditions. Expand
ECOLOGICAL RESTORATION OF SOUTHWESTERN PONDEROSA PINE ECOSYSTEMS: A BROAD PERSPECTIVE
The purpose of this paper is to promote a broad and flexible perspective on ecological restoration of Southwestern (U.S.) ponderosa pine forests. Ponderosa pine forests in the region have beenExpand
APPLIED HISTORICAL ECOLOGY: USING THE PAST TO MANAGE FOR THE FUTURE
TLDR
A montane grassland restoration project in northern New Mexico is described that was justified and guided by an historical sequence of aerial photographs showing progressive tree invasion during the 20th century, and a south- western network of fire histories illustrates the power of aggregating historical time series across spatial scales. Expand
Temperature as a potent driver of regional forest drought stress and tree mortality
As the global climate changes, drought is expected to reduce productivity and tree survival across many forests; however, the relative influence of climate variables on forest decline remains poorlyExpand

TLDR
The most rapid landscape-scale shift of a woody ecotones ever documented is reported: in northern New Mexico in the 1950s, the ecotone between semiarid ponderosa pine forest and pinon-juniper woodland shifted extensively and rapidly and persisted for 40 years. Expand
On underestimation of global vulnerability to tree mortality and forest die-off from hotter drought in the Anthropocene
Patterns, mechanisms, projections, and consequences of tree mortality and associated broad-scale forest die-off due to drought accompanied by warmer temperatures—“hotter drought”, an emergingExpand
Effects of biotic disturbances on forest carbon cycling in the United States and Canada
Forest insects and pathogens are major disturbance agents that have affected millions of hectares in North America in recent decades, implying significant impacts to the carbon (C) cycle. Here, weExpand
Tree die-off in response to global change-type drought: mortality insights from a decade of plant water potential measurements.
TLDR
These data suggest that pinon mortality was driven by protracted water stress, which remained substantially below their zero carbon assimilation point for at least 10 months prior to dying, in contrast to those of juniper, which rarely droppedbelow their zero-assimilation point. Expand
