                        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).
