Subject: Seminar 9/23/10 Nanosilver as an emerging factor in freshwater
community dynamics


The seminar committee of the Ecological Exposure Research Division
(EERD) of the United States Environmental Protection Agency's National
Exposure Research Laboratory in Cincinnati is pleased to invite you to
attend a seminar given by Dr. Randy Bernot (Assistant Professor of
Biology, Ball State University) next Thursday, September 23, 2010 from
1:00 - 1:45 in in the Andrew W. Breidenbach Environmental Research
Center auditorium located at 26 W. Martin Luther King Drive, Cincinnati,
OH 45269.

Dr. Bernot's seminar is entitled: ³Ecology with chemical contaminants:
Nanosilver as an emerging factor in freshwater community dynamics.²
Abstract below.

This seminar is part of EERD's monthly seminar series designed to
increase scientific engagement by providing opportunities to directly
interact with other scientists conducting research that solves
environmental problems.

If you plan to attend this seminar please contact Ken Fritz
([log in to unmask]; x7092), also please distribute to other faculty and
students who may be interested in attending.

Interactions among species and their environment largely determine the
ecological community dynamics that influence ecosystem processes and
patterns.  A growing number of researchers are explicitly incorporating
anthropogenic chemicals as environmental stressors on broader ecological
processes such as species interactions and diversity-productivity
relationships.  Research in my lab combines general ecological theory
with ecotoxicology by testing hypotheses about chemical effects on
aquatic organism vital rates and multi-species community dynamics.  We
are conducting a range of studies to determine the direct and indirect
effects of nanosilver, a manufactured nanomaterial, on freshwater
communities.  I will present data that integrates nanosilver into
predator functional responses, parasite-host interactions, and the
indirect effects of predators and parasites on benthic communities and
ecosystems.  I will also discuss how this framework of study can be used
to further integrate general ecology with ecotoxicology.
