Epidemiology and Food Security: Historically Linked,
Future of Promise
1:00 – 3:00 p.m. * 200 ABC
Section: Epidemiology/Ecology/Environmental Biology
Organizers/Moderators: Serge Savary, International Rice
Research Inst., Metro Manila, Philippines; Pierce A. Paul,
Ohio State Univ, Wooster, OH
Sponsoring Committees: Epidemiology, Crop Loss
Assessment and Risk Evaluation
Epidemiology has been inherently linked with food security.
As the world’s population continues to grow, agricultural
researchers will be faced with the important goal of meeting
the world’s food demand. Epidemiology is one of the areas
that can help contribute to addressing this issue. In order
to continue to improve food security, epidemiologists
need to provide adequate measures of agrosystem (and
ecosystems) performance, in relation with plant health. Also,
epidemiologists need to provide accurate, if not precise,
measurements of the efficiency and costs of management that
have many dimensions and units. Finally, epidemiologists
need to be able to generate scenarios for overall management
and thresholds for actions in complex, nonlinear systems.
This special session will examine the historical context of food
security and the role of epidemiology, highlight the current
state of how epidemiological research contributes to food
security, and discuss the future needs for epidemiologists to
continue to contribute to food security.

Harnessing Emerging Molecular and Statistical
Technologies for Analysis of Soilborne Pathosystems
1:00 -3:00 p.m. * 205 AB
Section: Epidemiology/Ecology/Environmental Biology
Organizers/Moderators: Zahi Atallah, USDA-ARS,
University of California-Davis, Davis, CA, Greg Browne,
USDA-ARS, University of California-Davis, Davis, CA
Sponsoring Committees: Soil Microbiology and Root Diseases
Many new and rapidly changing technologies are available
for characterizing microbial communities in soil. Molecular
biology advances now allow for the detection and
characterization of a myriad of soil microbes, including those
considered nonculturable. New statistical approaches permit
a quantitative examination of soil microbial communities.
However, optimization of these emerging technologies and a
comprehensive understanding of their limitations tend to be
elusive. We propose to organize a symposium highlighting
effective utilization of emerging molecular and statistical
methodologies for examining soil microbial communities.
The speakers will focus on practical challenges, such as 1)
selecting the most effective and appropriate methodologies to
examine various types of microbial communities mediating
or influencing soilborne diseases; 2) selecting appropriate
experimental designs, sampling methods, and sample sizes;
and 3) understanding and dealing with limitations of the
methodologies.

If We Had Known Then What We Know Now: Reflections
on Catastrophic Tree Diseases
1:00 – 3:00 p.m. * 205 CD
Section: Disease of Plants
Organizer: George W. Hudler, Cornell University, Ithaca, NY
Moderators: George W. Hudler, Cornell University, Ithaca,
NY, Jennifer Juzwik, USDA FS, St. Paul, MN
Sponsoring Committees: Forest Pathology
The establishment and spread of non-native, invasive forest
pathogens in the US during the 20th century have changed
forest composition, structure, and function in rural and urban
landscapes. Because recovery from an invasive pathogen is
typically an extremely long-term process, it is especially critical
to incorporate lessons from previous invasions by diverse
pathogens. Case studies covering historical perspectives on what
was done to contain, prevent spread, and mitigate each disease
through the century will be presented. This symposium will
focus on lessons learned from historical pathogen invasions to
improve our response to current and future threats.
1:00 p.m. S-42. Oak wilt; did our response match the
threat? D. APPEL (1). (1) Texas A&M University,
College Station, TX, U.S.A.
