The North Pacific marine environment has provided
a diverse and valuable series of ecosystem services to coastal communities
for many thousands of years. Ocean and land-based anthropogenic activities
are now widely recognized to have a strong influence on ecological processes
throughout the North Pacific marine ecosystem. Anthropogenic influences
such as commercial fishing, aquaculture, pollution, and urbanization
are particularly strong in coastal waters where they impose a wide variety
of multiple stressors that can impact fundamental ecosystem functions,
critical processes, and marine biodiversity. Changes in the physical
and biological environment perturb native communities, often resulting
in disruption of species interactions and trophic relationships that
can negatively impact productivity and diminish ecosystem resilience.
In addition, large scale processes such as regime shifts, ocean oscillations,
and climate variability can alter near-shore processes. For example,
introduced species can negatively impact native communities, and commercial
shipping and recreational activities can be a powerful vector for changes
in the geographic distribution of marine and estuarine species. Similarly,
changing ocean conditions have facilitated the continued pole-ward range
expansion of a number of marine organisms, often with unknown impacts
on the ecosystems they are moving into. Recent range expansion (e.g.,
Humboldt squid) and population eruptions (e.g., jellyfish) on both sides
of the Pacific have had negative consequences for native flora and fauna.
Application of an ecosystem-based approach to coastal management would
provide a template to better understand multiple stressors in coastal
systems. Continuing to study and manage these stressors independently
as single problems must be replaced by examining multiple stressors
within the context of the ecosystems they are altering. Further, global
climate change is expected to have clear consequences with respect to
future species introductions, establishment, and range expansion. Ignoring
complex interactions will only hinder management efforts. Thus, integrating
non-indigenous species invasions with existing anthropogenic stressors
will facilitate a holistic approach to addressing the challenges facing
our coastal marine ecosystems.
This session will explore the characterization, understanding, and
forecasting of the influence of multiple anthropogenic stressors in
North Pacific coastal ecosystems. For example, how do non-indigenous
species interact with other anthropogenic stressors? Contributed papers
will provide a higher-level overview of stressors in various North Pacific
ecosystems (e.g., overharvesting, urbanization, habitat alteration and
loss, mariculture, HABs, pollution, non-indigenous species, etc.) and
the types of impacts that have been observed, especially those linked
to changes in biodiversity and productivity (e.g., extinctions, species
interactions, trophic cascades).
