Type: Oral Presentation Session: Recent Growth Trends and Tree Mortality
Track: Recent growth changes and tree mortality
In California’s southern Sierra Nevada, air pollution in the form of ozone is a major ecosystem stressor. Additionally, climatic shifts are expected to exacerbate drought in the region, including in forests throughout Sequoia/Kings Canyon National Parks. In order to describe response to these compound stressors, our study asks: is the growth signature of drought in pine forests detectable, consi ... More

Track: Recent growth changes and tree mortality
Red spruce (Picea rubens Sarg.) diameter growth in the northeastern United States has decreased since the 1960s due to a combination of factors, including foliar winter injury predisposed by acidic deposition-induced calcium depletion. We assessed the influence of a severe region-wide winter injury event in 2003 on radial growth decline and the subsequent rebound of red spruce growth in stands i ... More

Track: Recent growth changes and tree mortality
Austrocedrus chilensis forests in northern Patagonia experience stand-level growth decline and mortality. While this disturbance has been subject of detailed study, the role of contributing factors such as climate variation and processes associated with stand development has just begun to be understood. We studied the influence of climatic variation and stand development on the radial growth decli ... More

Track: Recent growth changes and tree mortality
Across western North America, changes in climate during the late 20th and early 21st centuries have manifested in dramatic periods of tree mortality, such as those driven by wildfire, bark beetle outbreaks, and increased background mortality. This broad-scale mortality is understood to have important impacts on carbon cycling, with feedbacks to global climate change. Despite the importance of tree ... More

Track: Recent growth changes and tree mortality
Drought and insect infestations can lead to widespread tree mortality in forest ecosystems. However, models of forest dynamics are limited in their ability to simulate mortality during drought because the processes underlying tree death are poorly constrained. Tree allocation to defense is hypothesized to be a key element in tree avoidance of mortality, but there are few empirical tests of its i ... More
