abstract = {The contribution of certain contaminants to reproductive
failure in many avian species has been an ongoing concern.
Appropriate quantitative techniques have focused either on
the individual organisms by providing explicit
bioaccumulation dynamics or on whole ecosystems by looking
at the fate of the contaminant but fail to make the
necessary link via population dynamics of interacting
individuals. We used the individual-oriented approach in an
effort to quantify effects of chronic contaminant exposure
on individual birds. This was made possible by the use of an
object-oriented model, where individual birds are
interacting objects, and their actions are implemented by
passing to them appropriate messages. Using this modeling
approach a breeding colony of Great Blue Herons (Ardea
herodias) is simulated as an assemblage of interacting
individuals whose daily actions (foraging, growth, feeding
of the young) are simultaneously followed over short time
intervals for a nesting season. Spatial distribution of the
contaminants in prey resources is used on a cell by cell
basis and their effects on certain behavior characteristics
of adult birds (e.g. foraging efficiency, effects on flying
efficiency, parental care) are taken into account. Results
showed that sublethal effects could have a considerable
effect on colony success. Appropriate selection of endpoints
for risk assessment yields a variety of scenarios for colony
success. (C) 2003 Elsevier B.V. All rights reserved.},
