“Species distribution modeling” was recently ranked as one of the top five “research fronts” in ecology and the environmental sciences by ISI's Essential Science Indicators (Renner and Warton 2013), reflecting the importance of predicting how species distributions will respond to anthropogenic change. Unfortunately, species distribution models (SDMs) often perform poorly...
Evaluating stocking efficacy in an ecosystem undergoing oligotrophication
Yu-Chun Kao, Mark W. Rogers, David B. Bunnell
2018, Ecosystems (21) 600-618
Oligotrophication has negatively affected fisheries production in many freshwater ecosystems and could conceivably reduce the efficacy of stockings used to enhance fisheries. In Lake Michigan, offshore oligotrophication has occurred since the 1970s, owing to reductions in total phosphorus (TP) inputs and nearshore sequestration of TP by nonindigenous dreissenid mussels. We...

Richard A. Erickson, James E. Diffendorfer, Ryan Norris, Joanna A. Bieri, Julia Earl, Paula Federico, John Fryxell, Kevin Long, Brady J. Mattsson, Christine Sample, Ruscena Wiederholt, Wayne E. Thogmartin
2018, Journal of Applied Ecology (55) 108-117
Understanding and conserving migratory species requires a method for characterizing the seasonal flow of animals among habitats. Source-sink theory describes the metapopulation dynamics of species by classifying habitats as population sources (i.e. net contributors) or sinks (i.e. net substractors). Migratory species may have non-breeding habitats important to the species...
