Habitat heterogeneity and mammalian predatorprey interactions
1. In predator–prey theory, habitat heterogeneity can affect the relationship between kill rates and prey or predator density through its effect on the predator’s ability to search for, encounter, kill and consume its prey. Many studies of predator– prey interactions include the effect of spatial heterogeneity, but these are mostly based on species with restricted mobility or conducted in exper...
متن کاملCanopy interactions and physical stress gradients in subtidal communities.
Species interactions are integral drivers of community structure and can change from competitive to facilitative with increasing environmental stress. In subtidal marine ecosystems, however, interactions along physical stress gradients have seldom been tested. We observed seaweed canopy interactions across depth and latitudinal gradients to test whether light and temperature stress structured i...
متن کاملVariation in predator foraging behaviour changes predatorprey spatiotemporal dynamics
1. Foraging underlies the ability of all animals to acquire essential resources and thus provides a critical link to understand population dynamics. A key issue is how variation in foraging behaviour affects foraging efficiency and predator–prey interactions in spatially heterogeneous environments. However, there is very little quantitative information available on this topic. 2. We evaluated t...
