Invasive predator diet plasticity has implications for native fish conservation and invasive species suppression

Autor: Hayley C. Glassic, Christopher S. Guy, Lusha M. Tronstad, Dominique R. Lujan, Michelle A. Briggs, Lindsey K. Albertson, Todd M. Koel

Publikováno v: PLoS ONE, Vol 18, Iss 2 (2023)

Diet plasticity is a common behavior exhibited by piscivores to sustain predator biomass when preferred prey biomass is reduced. Invasive piscivore diet plasticity could complicate suppression success; thus, understanding invasive predator consumptio

Decomposition Rates of Suppression-Produced Fish Carcasses in a Large, Deep, High-Elevation Lake in North America

Autor: Hayley C. Glassic, Christopher S. Guy, Lusha M. Tronstad, Michelle A. Briggs, Lindsey K. Albertson, Dominique R. Lujan, Todd M. Koel

Publikováno v: Fishes, Vol 8, Iss 8, p 385 (2023)

The decomposition of vertebrates in lake ecosystems has been largely understudied despite being a vital part of ecosystem processes. Invasive lake trout (Salvelinus namaycush) invaded Yellowstone Lake and caused a decline in the native Yellowstone cu

Autor: Kaitlyn M. Furey, Hayley C. Glassic, Christopher S. Guy, Todd M. Koel, Jeffrey L. Arnold, Philip D. Doepke, Patricia E. Bigelow

Publikováno v: Journal of Freshwater Ecology, Vol 35, Iss 1, Pp 291-303 (2020)

Invasive species introduction and expansion is the second greatest threat to global biodiversity decline after habitat degradation. Introduced in the 1930s, the benthivorous Longnose Sucker (Catostomus catostomus) became established in Yellowstone La

Diets and Stable Isotope Signatures of Native and Nonnative Leucisid Fishes Advances Our Understanding of the Yellowstone Lake Food Web

Autor: Hayley C. Glassic, Christopher S. Guy, Todd M. Koel

Publikováno v: Fishes, Vol 6, Iss 4, p 51 (2021)

(1) Many forage fishes, such as Leucisids (minnows) have depauperate studies on diet composition or stable isotope signatures, as these fishes are often only viewed as food for higher trophic levels. The need exists to understand and document the die

Presence of Microplastics in the Food Web of the Largest High-Elevation Lake in North America

Autor: Stephanie C. Driscoll, Hayley C. Glassic, Christopher S. Guy, Todd M. Koel

Publikováno v: Water, Vol 13, Iss 3, p 264 (2021)

Microplastics have been documented in aquatic and terrestrial ecosystems throughout the world. However, few studies have investigated microplastics in freshwater fish diets. In this study, water samples and three trophic levels of a freshwater food w

Two Ocean Pass: An Alternative Hypothesis for the Invasion of Yellowstone Lake by Lake Trout, and Implications for Future Invasions

Autor: Todd M. Koel, Colleen R. Detjens, Alexander V. Zale

Publikováno v: Water, Vol 12, Iss 6, p 1629 (2020)

Preventing the interbasin transfer of aquatic invasive species is a high priority for natural resource managers. Such transfers can be made by humans or can occur by dispersal through connected waterways. A natural surface water connection between th
