Modeling hypolimnetic dissolved oxygen depletion using monitoring data.

Can J Fish Aquat Sci 2020 May;77(5):814-823

School of Natural Resources, University of Missouri, Columbia, MO 65211.

Eutrophication increases hypoxia in lakes and reservoirs, causing deleterious effects on biological communities. Quantitative models would help managers develop effective strategies to address hypoxia issues, but most existing models are limited in their applicability to lakes with temporally resolved dissolved oxygen data. We describe a hierarchical Bayesian model that predicts dissolved oxygen in lakes based on a mechanistic understanding of the factors that influence the development of hypoxia during summer stratification.

Mercury bioaccumulation increases with latitude in a coastal marine fish (Atlantic silverside, Menidia menidia).

Can J Fish Aquat Sci 2017 Jul 30;74(7):1009-1015. Epub 2016 Nov 30.

Human exposure to the neurotoxic methylmercury (MeHg) occurs primarily via the consumption of marine fish, but the processes underlying large-scale spatial variations in fish MeHg concentrations [MeHg], which influence human exposure, are not sufficiently understood. We used the Atlantic silverside (), an extensively studied model species and important forage fish, to examine latitudinal patterns in total Hg [Hg] and [MeHg]. Both [Hg] and [MeHg] significantly increased with latitude (0. Read More

Seasonal shift in the effect of predators on juvenile Atlantic salmon () energetics.

Can J Fish Aquat Sci 2011 Nov;68(12):2080-2089

Department of Biological Sciences, Dartmouth College, Hanover, NH 03755, USA.

Predator effects on prey populations are determined by the number of prey consumed and effects on the traits of surviving prey. Yet, effects of predators on prey traits are rarely evaluated in field studies. We measured the effects of predators on energetic traits (consumption and growth rates) of juvenile Atlantic salmon () in a large-scale field study. Read More
