英文摘要
This pilot project aims towards developing a proposal to apply basic
ecological food-web research to the closely related biomedical problem of
contaminant bioaccumulation in ecosystems. Bioaccumulated contaminants
threaten the health of organisms including humans that consume fish and
other organisms from the environment. Two primary activities are proposed.
The first establishes a rigorous connection between basic ecological issue
of food-web structure and the applied problem of calculating the potential
for species within ecosystems to bioaccumulate lipophilic toxic
contaminants. The activity involves theoretical, analytical and empirical
explorations. The second activity establishes a procedure to apply the
quantitative polymerase chain reaction (QPCR) to the analysis of feeding
relations among organisms. Specific pilot project tastes include 1)
conducting library research on the biomagnification factors associated
with feeding relations, 2) exploring the availability of data quantifying
the feeding relations of omnivores, and 3) evaluating QPCR methods in the
literature and in the lab that are both appropriate for analyzing feed
relations and use locally available equipment. It is anticipated that
completing these tasks will provide a strong foundation for a subsequent
proposal to estimate the bioaccumulative potential of ecosystems through
food-web studies.
