MISSION, OFFICERS, AND MEMBERSHIP The Physiological Ecology Section promotes research and teaching that explore interrelationships among the functions of organisms and their environments. As of January 2010, Kiona Ogle (University of Wyoming) completed her term as Secretary of the Section. Jennifer Funk (Chapman University) took over for a two-year term, with goals of working toward supporting student attendance at ESA and participation in the student awards competition, as well as recruiting innovative, inter-disciplinary symposia. Zoe Cardon (Marine Biological Laboratory) is serving her second year as President. During autumn 2010, a new President will be elected. Webmaster Rob Jackson continues his long-term service to the section; our web site is http://www.biology.duke.edu/jackson/ecophys/.
We have broad section membership, and many members are also part of the Biogeosciences, Education, Rangeland Ecology, Researchers at Undergraduate Institutions, Soil Ecology, Urban Ecosystem Ecology, and Vegetation Sections. This year, our Section-sponsored symposium planned for Pittsburgh (see below) -- organized by Lauren Buckley (Univ. of North Carolina), Amy Angert (Colorado State Univ.), and Lisa Crozier (NOAA Fisheries) -- aims to meld understanding of the traits/ecology/evolution of organisms (the "legacy of the past") with our need to understand/predict species ranges in a warmed world (the "challenge of our future").
First, THANK YOU to all the judges who make it possible to offer these awards each year. Your efforts keep our Section’s activities going; we greatly appreciate your willingness to serve.

SECTION ACTIVITIES AT THE PITTSBURGH 2010 ESA MEETING
Mixer and Business Meeting
At Pittsburgh, August 4 2010, our Physiological Ecology Section will hold its mixer and business meeting on Wednesday evening, 6:30 PM-8:00 PM Blrm BC, David L Lawrence Convention Center. Come early, come hungry, come thirsty, and come ready to discuss at least two (maybe more) section opportunities:
(1) How we can best support ESA’s initiative in Planetary Stewardship?
(2) How we can best allocate our new Student Travel funds, $2500 each year, for the next 5 years?
Sponsored symposium and organized oral session at ESA in Pittsburgh, 2010
Tuesday, August 3, 2010: 1:30 PM-5:00 PM , Blrm A, David L Lawrence Convention Center
SYMP 7 - Does Biology (physiology, ecology, evolution) Matter in Predicting How Species’ Distributions Will Respond to Climate Change?
Organizer and moderator: Lauren B. Buckley, University of North Carolina at Chapel Hill
Co-organizers: Amy L. Angert, Colorado State University and Lisa G. Crozier, NOAA Fisheries
The symposium will ask what biological details should be considered when predicting climate-induced shifts in species’ ranges through investigating past responses to paleoclimate fluctuations, whether physiology and life history can predict responses, and how ecology and evolution influence responses. We will attempt to bridge between small-scale experimental studies where the biological details are thought to be crucial and broad-scale modeling efforts where the biological details are ignored. We intend the symposium to spur discussions that will guide the next generation of species’ distribution models.

OOS 19 - Gaps In Predicting Vegetation Change - Physiological and Genetic Variation and Extreme Events
Organizer: Vincent Gutschick, Global Change Consulting Consortium, Inc.
Moderator: Hormoz BassiriRad, University of Illinois at Chicago
Changes in climate, as well as direct effects of rising CO2 as a photosynthetic substrate, are inducing changes in the distribution of plant species, as well as their physiological performance, ecological relations (competition, pollination, disease occurrence), and evolution. Prediction of such changes is clearly important for ecology, as also for climatology, via vegetation feedbacks to the carbon, nutrient, and water cycles and regional albedos. Current dynamic vegetation models use climatic responses of vegetation, commonly statistical, with a modest inclusion of physiological responsiveness. The climatic models fail to account for abiotic (and biotic) extreme events, which are poorly characterized, if at all, by gross climatic averages over time and space. Moreover, novel climates are likely to arise, for which there is no basis to estimate plant responses. Rarely included in the models are the direct effects of CO2 on physiological performance, particularly resource-use efficiencies. Neither do models include the full, striking diversity of direct CO2 responses among species. Dynamic models are also limited in their capability to represent time lags, on annual to multi-decadal scales, arising from dispersal dynamics and from rapid changes in community structure in pulse-dominated ecosystems. Finally, there is dramatic evidence of constraint in vegetation responses at the population level and above, as a result of population genetic structure. We review the evidence for vegetation changes, the challenges in proper attribution of vegetation changes, and the capabilities of models, current and future.

Section booth at the ESA meetings: In 2009, we established the Physiological Ecology Section Booth at the annual meeting. The booth served as a Section focal point, featuring:
The raffle attracted the attention of an anonymous donor who has now promised $2500 per year for the next 5 years to support student attendance at the meetings. We’ll have another booth this year in Pittsburgh – be sure to come by!
