year effects may have been as high as $47 million. More probable estimates of
the oil spill s actual social costs are likely less than these amounts.
Precise determination of the accident s impacts is constrained by the dynamic
interaction of numerous biological and economic variables.

Dynamics in a Fluctuating Environment. Canadian Journal of Fisheries
and Aquatic Sciences, 51(12):2665-2672.
Large fluctuations in the abundance of marine fish are revealed in scale
deposits from before the twentieth century and are thought to be
environmentally induced. We investigate how a fluctuating environment and
predation may combine to cause abrupt shifts in fish abundance on decadal time
scales. For example, the biomass of Pacific herring (Clupea pallasi) off
Vancouver Island appears to be negatively related to sea surface temperature
(SST) and the abundance of its predator, Pacific hake (Merluccius productus).
We used first-order differential equations to develop a two species, predatorprey
model faced with stochastic variability. A nonlinear, predator
functional response potentially gives rise to multiple equilibrium abundance
levels. Environmental variability was simulated as red noise (variance is a
decreasing function of frequency) with a spectrum derived from SST data.
Stochastic variations caused the predator-prey abundances to shift between
high and low equilibrium levels. Fishing the prey population can precipitate
collapses to the low equilibrium level and prolong the time to recovery. When
run with actual catches and SST anomalies from 1951 to 1988, the model
simulated prey abundances with a pattern similar to the observed herring
biomass.

This bibliography is subdivided into four main topics or sections;
ecosystems, coastal water body conditions, natural disasters, and resource
management. In the ecosystems section, emphasis is placed on organisms in
their environment on the major coastlines of the U.S. In the second section,
coastal water body conditions, the environment itself is emphasized.
References were found for the Alaskan coast, but none were found for Hawaii.
The third section, coastal water body conditions, the environment itself is
emphasized. References were found for the Alaskan coast, but none were found
for Hawaii. The third section, on natural disasters, emphasizes environmental
impacts resulting from natural phenomena. Guidelines, planning and management
reports, modeling documents, strategic and restoration plans, and
environmental economics related to sustainability are included in the fourth
section, resource management. Author, geographic, and subject indices are
provided.

Foraging Predators and Parasitoids." Journal of Animal Ecology,
48:335-351.
The paper bridges the gap between optimal foraging models and predatorprey
or parasitoid-host population models. The parasitoid optimal foraging
model that we derive assumes each individual parasitoid to maximize its rate
of encounter with healthy hosts in a patchy environment. The model is used to
generate the searching strategy of a population of parasitoids, from which
their overall searching efficiency can be calculated. We then explore the
