Data from: Experimental duration and predator satiation levels systematically affect functional response parameters
Empirical feeding studies where density-dependent consumption rates are fitted to functional response models are often used to parameterize the interaction strengths in models of population or food-web dynamics. However, the relationship between functional response parameter estimates from short-ter...

Empirical feeding studies where density-dependent consumption rates are fitted to functional response models are often used to parameterize the interaction strengths in models of population or food-web dynamics. However, the relationship between functional response parameter estimates from short-term feeding studies and real-world, long-term, trophic interaction strengths remains largely unexamined. In a critical first step to address this void, we tested for systematic effects of experimental duration and predator satiation on the estimate of functional response parameters, namely attack rate and handling time. Analyzing a large data set covering a wide range of predator taxa and body masses we show that attack rates decrease with increasing experimental duration, and that handling times of starved predators are consistently shorter than those of satiated predators. Therefore, both the experimental duration and the predator satiation level have a strong and systematic impact on the predictions of population dynamics and food-web stability. Our study highlights potential pitfalls at the intersection of empirical and theoretical applications of functional responses. We conclude our study with some practical suggestions for how these implications should be addressed in the future to improve predictive abilities and realism in models of predator-prey interactions.
