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.

Body size is a key functional trait that has declined in many biological communities, partly due to changes in individual growth rates in response to climate warming. However, our understanding of gr....

Does availability of juvenile refuge affect size structure of adults? Uszko et al. show that size of streams used as nurseries impacts growth and size structure of lake trout by controlling the strength of cannibalistic mortality and resource competition.

Warming can affect many physiological processes. But any attempt to scale up individual-level processes to population-level consequences must assume a relationship between temperature & the strength of density dependence. But what does it look like? In our new paper, we tried to find out.

Strengthening of negative density dependence mediates population decline at high temperatures
