Roundtable for next week will be presented by Emma Hodgson, a graduate student in the School of Aquatic and Fishery Sciences at the University of Washington, Seattle.

Abstract:

Marine species are experiencing a suite of novel stressors from anthropogenic activities that have impacts at multiple scales. Ecological risk assessment is commonly used to judge the consequence of novel stressors to species, but usually without consideration of the life history of organisms. Most marine species vary throughout their life history in their spatio-temporal distributions in the water column, their responses to external pressures, and their level of contribution to the population overall. Better incorporating our understanding of those differences between life stages provides an opportunity to advance our understanding of the consequences of stress at the population level. This work advances approaches to ecological risk assessment and cumulative impacts assessment by explicitly incorporating life stage exposure, sensitivity, and importance to population growth rate.
