Mark Novak, @kecoblentz.bsky.social, John DeLong FTW - a very cool paper I need to dig carefully through!
Novak et al. derive a functional response model that unifies Holling’s classical forms. The model clarifies when linearity can be a mechanistically-reasoned description of predator feeding rates and the impact it has on predator-prey dynamics.

Food-washing monkeys recognize the law of diminishing returns
Monkeys are sensitive to foods coated with tooth-damaging sand and will invest time and energy to eliminate sand, but dominance rank affects the effort allocated to cleaning behaviors.
