Predator and Prey Habitat Selection Games: the Effects of How Prey Balance Foraging and Predation Risk

The spatial distributions of predators and prey can be shaped by both intraand interspecific games. Most predator–prey studies, however, have ignored the interspecific game by focusing on how either predators or prey distribute themselves while holding the distribution of the other species fixed. We use genetic algorithms to examine how the distributional outcome of the game between predators a...

Functional responses of the intertidal amphipod Echinogammarus marinus: effects of prey supply, model selection and habitat complexity

The influence of predation in structuring ecological communities can be informed by examining the shape and magnitude of the functional response of predators towards prey. We derived functional responses of the ubiquitous intertidal amphipod Echinogammarus marinus towards one of its preferred prey species, the isopod Jaera nordmanni. First, we examined the form of the functional response where ...

A two-level problem: habitat selection in relation to prey abundance in an ambush predator, the speckled rattlesnake (Crotalus mitchellii)

Understanding how food distribution influences habitat choice is a central goal of behavioural ecology. Because animals select habitats at different scales, and because the selection criteria used may be scale-dependent, studies examining the significance of food in relation to habitat selection should ideally incorporate more than one spatial scale. We relied on spatial ecology data and prey a...

Oligotyping reveals community level habitat selection within the genus Vibrio

The genus Vibrio is a metabolically diverse group of facultative anaerobic bacteria, common in aquatic environments and marine hosts. The genus contains several species of importance to human health and aquaculture, including the causative agents of human cholera and fish vibriosis. Vibrios display a wide variety of known life histories, from opportunistic pathogens to long-standing symbionts w...
