Predation Risk Influences the Diving Behavior of a Marine Mesopredator
Exploring factors that influence diving behavior is critical to understanding energy budgets, habitat use, and exploitation rates of prey. Optimal diving behavior studies have focused primarily on trade-offs between oxygen recovery at the surface and energy intake at depth. General predictions from these models are often supported by empirical data, but a mismatch exists between theory and data...
متن کاملAnthropogenic noise disrupts use of vocal information about predation risk.
Anthropogenic noise is rapidly becoming a universal environmental feature. While the impacts of such additional noise on avian sexual signals are well documented, our understanding of its effect in other terrestrial taxa, on other vocalisations, and on receivers is more limited. Little is known, for example, about the influence of anthropogenic noise on responses to vocalisations relating to pr...

متن کاملPredation risk influences adaptive morphological variation in fish populations.
Predators can cause a shift in both density and frequency of a prey phenotype that may lead to phenotypic divergence through natural selection. What is less investigated is that predators have a variety of indirect effects on prey that could potentially have large evolutionary responses. We conducted a pond experiment to test whether differences in predation risk in different habitats caused sh...
