Nate Pollesch, Network analytics for Adverse Outcome Pathways
ABSTRACT: Adverse Outcome Pathways (AOPs) organize toxicological knowledge from the molecular level up to the population level, providing evidence-based causal linkages at each step. The AOPWiki serves as a repository of AOPs. With the international adoption of the AOP framework, the AOPwiki is growing and new knowledge is emerging from unforeseen linkages among AOPs. This presentation will show recently developed network analysis techniques for sorting and prioritizing AOP knowledge derived from the AOPWiki network
Bryan Matthias, Status and trends of the Lake Superior Ecosystem
ABSTRACT: Lake Superior is unique among the Laurentian Great Lakes in that it has ecological communities dominated by native species in both nearshore and offshore areas. However, the Lake Superior ecosystem is undergoing significant changes to both nearshore and offshore food webs, including prey fish population declines. These changes are likely affecting ecosystem functions, trophic dynamics, and fishery yields. The objective of this study was to use EcoPath with EcoSim to explore how the declines in the prey fish populations influence Lake Superior ecosystem dynamics. The secondary objective was to assess potential ecosystem-level effects of changing Sea Lamprey management strategies, specifically, 1) if we double or 2) if we halve the Sea Lamprey exploitation rate. We focus on the population-level responses of the native piscivores, Lean and Siscowet Lake Trout Salvelinus namaycush namaycush and S. n. siscowet, along with the major prey fish Coregonus spp., Osmerus mordax, Cottus spp., Myoxocephalus thompsonii.
