Michael Dodrill, Charles Yackulic, Theodore Kennedy, Michael D. Yard, Josh Korman
2021, Canadian Journal of Fisheries and Aquatic Sciences (78) 809-819
Drift-feeding fish are typically considered size-selective predators. Yet, few studies have explicitly tested which aspect of prey “size” best explains size selection by drift-foraging fish. Here, we develop a Bayesian discrete choice model to evaluate how attributes of both prey and predator simultaneously influence size-selective foraging. We apply the model...
