95th ESA Annual Meeting, August 1-6, 2010

Post by edfrank » Thu Jun 17, 2010 7:33 pm


ENTS member Ryan McEwan passed on this note about the dendrochronology session at the upcomming ESA Meeting this August.
I wanted to draw your attention to a Eastern Deciduous Forest dendroecology session at the upcoming ESA meeting. Neil Pederson and I are organizers. If you are at ESA, I hope you have time to stop by.
The main theme of the meeting is Global Warming:
Global Warming: The legacy of our past, the challenge for our future


Increases in surface temperatures on a global scale over recent decades support past predictions of global warming as a theory. Although this pattern may be attributable to long-term cycles in global temperatures and atmospheric CO₂, data sets examining climate phenomena at multi-millennial time scales (e.g., the Lake Vostok data) clearly demonstrate that current trends are far out of range of cyclic change alone. The accumulation of such data has led the United National Environment Programme’s Intergovernmental Panel on Climate Change to the unavoidable conclusion: human activity has brought about unprecedented rates of temperature increase on a global scale through release of greenhouse gases primarily associated with combustion of fossil fuels.

In contrast to the high level of certainty of the phenomenon of global warming, environmental scientists—including and especially ecologists—have been less certain of its far-reaching effects, although recent evidence suggests that these effects can be far ranging: from altered plant phenology to enhanced occurrence of disease to exacerbated glacial retreat to increased frequency and intensity of tropical storms. Indeed, global warming will continue to exert influence at virtually all levels of ecological organization, from individuals to landscapes. At its 2010 Annual Meeting in Pittsburgh, PA, the Ecological Society of America will place global warming at center stage to draw a critical combination of scientists, policy makers, and concerned citizens to understand further its causes and consequences and to elucidate a clear scenario for addressing what is perhaps the most serious environmental threat facing the biosphere.

OOS 30 - Reconstruction of Climate, Fire, and Forest Dynamics in Eastern North America via Dendroecology; Gleaning New Perspective from Ancient Trees

Wednesday, August 4, 2010: 1:30 PM-5:00 PM
301-302, David L Lawrence Convention Center

Forests across much of the Eastern Deciduous Forest (EDF) are characterized by ongoing dynamics in species composition, structure and ecosystem function. The drivers of these dynamics are complex, and likely interactive. Tree-ring analysis allows for the simultaneous assessment of long-term forest dynamics, and the factors driving these dynamics. In recent years, tree-ring analysis has been used in new ways, and in new ecosystems, to understand the causes and consequences of dynamics in the EDF. In this session, we bring together newly established scientists and some of the most well-known voices in eastern forest dendroecology, representing a variety of perspectives, with the intention of synthesizing scientific understanding, and seeking new paths forward. The session will begin with a review of the history and progress in eastern forest dendroecology by Dr. Dave Orwig, who will also present ideas for new research directions. Then consecutive presentations by Drs. Dave Stahle and Neil Pederson will set the climatic context by reviewing climate dynamics in eastern North America over the last 500-1,000 years. These talks will also present data on how stand dynamics at local and regional scales might be tied to climatic variation. While focusing on different systems, Drs. Amy Hessl and Tony D’Amato will give consecutive talks that address short and long-term carbon storage in deciduous forests as influenced by stand dynamics. Following the break, we lead off with a talk by Dr. Carolyn Copenheaver, who works on forest dynamics in the southern Appalachian region. We then have two open spots to be filled by the program chair. To summarize the session, we have consecutive talks by two well-known tree-ring scientists, Drs. Alan White and Rich Guyette, who focus on dynamics at broad spatial scales. Dr. White’s work focuses primarily on gap-phase disturbance processes (other than fire) in the cooler and moist northeastern region of the EDF, while Dr. Guyette’s work has been focused on fire histories of the drier and continental climate of the western edge of the EDF. The planned contrast of dynamics at the extremes of the EDF climatic spectrum, with contrasting disturbance regimes, ought to highlight the diversity of ecological processes at work in these systems and highlight potential for collaboration among researchers.

"I love science and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awe by nature. Science is not meant to cure us of mystery, but to reinvent and revigorate it." by Robert M. Sapolsky

Looks like an awesome ESA session! I'm glad it doesn't overlap the session I'm speaking in--I'd hate to miss out on it.
