Land development and road salt usage drive long-term changes in major-ion chemistry of streamwater in six exurban and suburban watersheds, southeastern Pennsylvania, 1999-2019
Marissa Lee Rossi, Peleg Kremer, Charles A. Cravotta III, Krista E. Seng, Steven T. Goldsmith
2023, Frontiers in Environmental Science (11)
In urbanized areas, the “freshwater salinization syndrome” (FSS), which pertains to long-term increases in concentrations of major ions and metals in fresh surface waters, has been attributed to road salt application. In addition to FSS, the water composition changes as an influx of sodium (Na+) in recharge may displace calcium...
Evaluating population trends of juvenile Atlantic Sturgeon at low abundance in a dynamic estuarine environment (Hudson River, New York)
Mark Richard Dufour, Song S. Qian
2023, Fisheries Management and Ecology (30) 507-520
Evaluating population trends in dynamic estuarine environments can be challenging, especially when survey data include a high percentage of zero observations. In fishery-independent surveys, zeros that come from reduced susceptibility to sample gears and reduced availability of the population to the survey impact survey catchability and negatively bias relative abundance...
A hierarchical modelling framework for estimating individual- and population-level reproductive success from movement data
Joseph Michael Eisaguirre, Perry J. Williams, Julia C. Brockman, Stephen B. Lewis, Christopher P. Barger, Greg A. Breed, Travis L. Booms
2023, Methods in Ecology and Evolution (14) 2110-2122
Rapidly advancing animal telemetry technologies paired with new statistical models can provide insight into the behaviour of otherwise unobservable free-living animals. Changes in behaviour apparent from pairing telemetry with statistical models often occur as animals undertake key life-history activities, such as reproduction. For many species that are secretive or...

James E. McKenna Jr., Anthony David
2023, The Northeastern Naturalist (30) 1-71
Biodiversity is responsible for important ecological processes like productivity and ecosystem stability, and rare species are a major component of biodiversity. Rarity increases a species' vulnerability to disturbances and also makes them difficult to study. Globally, species of freshwater systems are some of the most...

Dynamic population models with temporal preferential sampling to infer phenology
Michael Schwob, Mevin B. Hooten, Travis Mcdevitt-Galles
2023, Journal of Agricultural, Biological, and Environmental Statistics (28) 774-791
To study population dynamics, ecologists and wildlife biologists typically use relative abundance data, which may be subject to temporal preferential sampling. Temporal preferential sampling occurs when the times at which observations are made and the latent process of interest are conditionally dependent. To account for preferential...
