Walleye (Sander vitreus) are an ecologically important species managed for recreational, tribal, and commercial harvest. Walleye prefer cool water and low light conditions, and therefore changing water temperature and clarity potentially impacts walleye habitat and populations across the landscape. Using survey data collected from 1993 to 2018 from...
Territories within groups: The dynamic competition of drift-feeding juvenile Chinook salmon in 3-dimensional space
Jason R. Neuswanger, Amanda E. Rosenberger, M. S. Wipfli, Nicholas F. Hughes
2023, Canadian Journal of Fisheries and Aquatic Sciences (80) 346-359
Salmonid populations are often regulated by territorial competition among juveniles for food and space. In the canonical view, salmonid territories are spaced horizontally across the river bottom in a 2-D mosaic. However, some juveniles instead feed in tight, three-dimensional (3-D) social groups. To investigate whether territoriality is possible within such...
A comprehensive multi-state conditional occupancy model for evaluating interactions of non-native and native species
Patti J. Wohner, Paul D. Scheerer, Michael H. Meeuwig, James Peterson
2023, Frontiers in Ecology and Evolution (10)
A major challenge in ecology is disentangling interactions of non-native, potentially invasive species on native species. Conditional two-species occupancy models examine the effects of dominant species (e.g., non-native) on subordinate species (e.g., native) while considering the possibility that occupancy of one species may affect occupancy and/ or detection of...
