Heritable intraspecific variation among prey in size and movement interact to shape predation risk and potential natural selection

The paper examines how heritable variation in body size and movement traits of Paramecium caudatum affects predation risk by copepods, revealing independent selection pressures on these traits.

Ecological boundaries and constraints on viable eco-evolutionary pathways

The paper models predator evolution to show that ecological boundaries constrain viable eco-evolutionary pathways by limiting populations to those that avoid extinction.

Predator feeding rates may often be unsaturated under typical prey densities

The paper calculates a feeding rate saturation index using two databases and finds that predator feeding rates may often be unsaturated at natural prey densities.

Quantifying predator functional responses under field conditions reveals interactive effects of temperature and interference with sex and stage.

The paper measures predator functional responses in zebra jumping spiders under field conditions, finding sex/stage differences, temperature effects, and interference interactions.

Estimating predator functional responses using the times between prey captures

This paper introduces a new method to estimate predator functional responses by analyzing the time between prey captures, showing it reliably estimates parameters with fewer trials.

Nonlinear functional responses and ecological pleiotropy alter the strength and likelihood of disruptive selection in consumers

This paper investigates how nonlinear functional responses and ecological pleiotropy affect disruptive selection in consumers, finding that handling times and interference alter its strength and likelihood.

Quantifying predator dependence in the functional response of generalist predators.

The paper evaluates predator dependence in generalist predators using field surveys and experiments, finding weak predator dependence closer to prey dependence than ratio dependence.
