Activity Report for AFI Projects

AFI ComplexityActivity 07: Evaluate sublethal and chronic effects of individual and multiple contaminants on algal and benthic macroinvertebrate communities and individual taxaMindy Armstead2017-12-05 (Mandee Wilson)

Daniel Brady and Geneve Edwards (coauthors Mindy Armstead and Mandee Wilson) presented a poster at the Society of Environmental Toxicology and Chemistry (SETAC) North America 38th Annual Meeting in Minneapolis November 14, 2017 entitled “Comparative analysis of toxicity of simulated mine effluent on native Ephemeroptera taxa”.

AFI ComplexityActivity 09: Use of mesocosms and field studies to examine lotic water column microbial community dynamics, the influence of environmental and toxicological factors on these communities using genomic approaches, and the relationship between microbial...Gary Schultz2017-12-05 (Mandee Wilson)

Progress Completed: • Continued data analysis and work on manuscript describing the existence of a core bacterial community in lotic systems and controls on that community. • Capstone student (Maggie Hager) completed experiment examining the metabolic potential of bacterial communities from local soils. Data were analyzed and presentation/poster is being prepared to meet Capstone requirements. • Presented “Structure, resilience, and fate of large river bacterial communities” at ORBCRE meeting – September 28. • Continued collection of samples examining bacterial community structure over seasonal scales. • Published a manuscript acknowledging RII o Schultz, G. E., Jr., J. J. Kovatch, and H. Hertler (2017) Potential Impact of Coastal Development on Nearshore…

AFI ComplexityActivity 15: Biogeochemical and microbial impacts of mining activity on stream benthic communitiesJennifer Mosher2017-12-05 (Mandee Wilson)

Fall 2017: We used infield bioreactors to examine microbial community assembly and succession. We found that planktonic bacterial communities were sensitive to groundwater manipulations, while biofilm communities were not. Manuscript under review at PLOS One: “Use of in-field bioreactors demonstrate groundwater filtration influences planktonic bacterial community assembly, but not biofilm composition” Mosher lab, in collaboration with ORNL.
