Temperature sensitivity of drought-induced tree mortality portends increased regional die-off under global-change-type drought.
Large-scale biogeographical shifts in vegetation are predicted in response to the altered precipitation and temperature regimes associated with global climate change. Vegetation shifts have profound ecological impacts and are an important climate-ecosystem feedback through their alteration of carbon, water, and energy exchanges of the land surface. Of particular concern is the potential for war...
متن کاملToward an index of desiccation time to tree mortality under drought.
Research in plant hydraulics has provided important insights into plant responses to drought and species absolute drought tolerance. However, our ability to predict when plants will die from hydraulic failure under extreme drought is limited by a lack of knowledge with regards to the dynamics of plant desiccation following stomatal closure. Thus, we develop a simple hydraulics model based on br...
متن کاملTree mortality predicted from drought-induced vascular damage
The projected responses of forest ecosystems to warming and drying associated with twenty-first-century climate change vary widely from resiliency to widespread tree mortality1–3. Current vegetation models lack the ability to account for mortality of overstorey trees during extreme drought owing to uncertainties in mechanisms and thresholds causing mortality4,5. Here we assess the causes of tre...
متن کاملDrought-induced tree mortality: from discrete observations to comprehensive research.
There is an increasing need for a global monitoring network to assess rates of tree mortality. In spite of numerous reports of tree death, mostly linked to climate change and related droughts, quantitative assessments of tree mortality rates and the magnitude of tree mortality events are largely missing ( Hartmann et al. 2015). Except for human-caused deforestation, the largest forest losses in...
متن کاملEvaluating spatial patterns of drought-induced tree mortality in a coastal California pine forest
In a coastal, fog-influenced forest on Santa Cruz Island in southern California, we observed mortality of Bishop pine (Pinus muricata D.Don) trees following a brief (2 year), yet intense, drought. While anecdotal evidence indicates that drought-induced Bishop pine mortality has occurred in the past in the stand we studied, this is the first attempt to capture the spatial distribution of mortali...
