Natural Resources Research InstituteItem Are Your Paleoecological Indicators Telling the Truth? (2014)(2014) Reavie, Euan; University of Minnesota Duluth. Natural Resources Research Institute; Heathcote, Adam J; American Geophysical UnionInferring condition from fossil biological assemblages assumes a strong relationship between the variable you want to infer and patterns in the assemblages. In recent years it has become apparent that several species-based indices to infer environmental conditions in paleorecords are providing meaningless results. The following are steps you can take to ensure valid reconstructions. This poster demonstrates a phosphorus inference model based on Great Lakes diatom assemblages, but these methods are easily transferred to many indicators; e.g. foraminifera/sealevel, chironomids/oxygen, diatoms/salinity, etc.Item Center for Water and the Environment Publications and Grants, 1985-1991(University of Minnesota Duluth, 1992) University of Minnesota Duluth. Natural Resources Research InstituteItem The Ecological History of Lake Erie According to Algae (2014)(2014) Allinger, Lisa E; Reavie, Euan; University of Minnesota Duluth. Natural Resources Research InstituteLake Erie is well known for its cultural perturbations with an extensive history of monitoring and paleolimnoloigcal studies, particularly those using diatoms, that present evidence of major change in the lake’s environmental quality. The lake’s biological and physical processes are strongly affected by its topography and division into three basins. Species known to be tolerant to eutrophic conditions and those common in oligotrophic to mesotrophic lakes were relatively abundant in presettlement assemblages, inferring that the lake was at least seasonally productive prior to Euro-American settlement. Overall abundance of diatoms was relatively low during presettlement, but relative abundance was high for some speciesItem The Ecological History of Lake Ontario According to Phytoplankton (2014)(2014) Allinger, Lisa E; Reavie, Euan; University of Minnesota Duluth.

Natural Resources Research InstituteItem If You Build It, Will They Come? Breeding Birds (Expected and Not) of an Abandoned Taconite Mining Area (2015-12-17)(2015) Wilson, Steve; University of Minnesota Duluth. Natural Resources Research InstituteSteve Wilson has spent over 200 hours during the last four summers searching for birds in what may be Minnesota’s least-birded habitat: the mined areas of Minnesota’s Iron Range. He speculates that more westerly bird species might colonize the rock barrens and grasslands of the Iron Range, which bear a striking resemblance to habitats typically found much further west. What he found may surprise you, and help inform whether, and how, we manipulate bird habitats in response to climate disruption.Item NRRI Collection of Miscellaneous Reports Pt. 2(University of Minnesota Duluth, 2000) University of Minnesota Duluth.
