Models of high-dimensional environmental and ecological data- Brian Gray

An intern would have the opportunity to work on GLMMs issues—or use already-proposed models to tackle natural resource questions that are multivariate in nature. The intern would not be limited to the use of parametric models; concerns with making inferences from multivariate ecological data may be addressed using machine learning or other approaches.

Fighting the Tide: Combating Coral Disease and Disappearance Within the Florida Reef Tract Using Models- Daniel Walsh

In an unprecedented large-scale mortality event, Florida has lost >90% of many coral species. This event is unusual due to its expansive spatial extent, the number of affected species (at least 21 scleractinian coral species), and severity of losses (> 95% for Dendrogyra cylindrus), effectively eliminating some species from the tract.

Quantifying nutrient retention and transformation in rivermouths- James Larson

Rivermouths and other areas of the Great Lakes nearshore zone are the interface between the Lakes and the human communities that surround them. These areas provide abundant ecosystem services, including those related to provisioning services (food and water supply), cultural services (recreation and tourism) and regulating services (water quality regulation).

Estimating trends in river and stream water temperature using improved statistical models- Bryan Gray

Interest in the effects of climate change will continue to spur efforts to model changes in river and stream temperatures. Such changes may have important effects on aquatic organisms. A challenge is that statistical efforts should not rely on standard linear models when water temperatures span intermediate values and either low or high values (<5 °C or >25 °C). ...
