In defense of the original Type I functional response: The frequency and population-dynamic effects of feeding on multiple prey at a time Open
Ecologists differ in the degree to which they consider the linear Type I functional response to be an unrealistic versus sufficient representation of predator feeding rates. Empiricists tend to consider it unsuitably non-mechanistic and th…

Predator feeding rates may often be unsaturated under typical prey densities Open
Predator feeding rates (described by their functional response) must saturate at high prey densities. Although thousands of manipulative functional response experiments show feeding rate saturation at high densities under controlled condit…

Effects of predator novelty on intraguild predation communities with adaptive prey defense Open
Understanding coexistence within community modules such as intraguild predation (IGP), where an omnivore both preys on and competes with an intermediate consumer for a shared resource, has provided insight into the mechanisms that promote …

High variation in handling times confers 35-year stability to predator feeding rates despite altered prey abundances and apparent diet proportions Open
Historical resurveys of ecological communities are important for placing the structure of modern ecosystems in context. Rarely, however, are snapshot surveys alone sufficient for providing direct insight into the rates of ecological proces…

Kelp-forest dynamics controlled by substrate complexity Open
Significance Kelp forests are declining worldwide due to varied combinations of environmental change and the trophic downgrading of urchin-controlling predators. These processes have increased the frequency and extent of rapid, nonlinear s…

PressPurt: network sensitivity to press perturbations under interaction uncertainty Open
While the use of networks to understand how complex systems respond to perturbations is pervasive across scientific disciplines, the uncertainty associated with estimates of pairwise interaction strengths (edge weights) remains rarely cons…

Data and code from: Nestedness patterns and the dual nature of community reassembly in California streams: a multivariate permutation‐based approach Open
Many factors contribute to the nonrandom processes of extinctions and invasions that are changing the structure of ecological communities worldwide. These factors include the attributes of the species, their abiotic environment, and the in…

Trematode parasites exceed aquatic insect biomass in Oregon stream food webs Open
Although parasites are increasingly recognized for their ecosystem roles, it is often assumed that free‐living organisms dominate animal biomass in most ecosystems and therefore provide the primary pathways for energy transfer. To examine …

Hidden layers of density dependence in consumer feeding rates Open
Functional responses relate a consumer’s feeding rates to variation in its abiotic and biotic environment, providing insight into consumer behavior and fitness, and underpinning population and food-web dynamics. Despite their broad relevan…

Systematic bias in studies of consumer functional responses Open
Functional responses are a cornerstone to our understanding of consumer-resource interactions, so how to best describe them using models has been actively debated. Here we focus on the consumer dependence of functional responses to evidenc…
