| Summary: | Anthropogenic noise is a pervasive and increasing source of disturbance to wildlife. Marine mammals exhibit behavioral and physiological responses to naval sonar and other sound sources. The lost foraging opportunities and elevated locomotor effort associated with sonar disturbance likely carry energetic costs, which may lead to population-level consequences. We modeled the energetic costs associated with behavioral responses using (1) empirical datasets of cetacean feeding rates and prey characteristics and (2) allometry of swimming performance and metabolic rates. We applied our model to compare the short-term (i.e., the scale of the disturbance response; hours to days) energetic costs of a variety of observed behavioral responses. Efficient foragers (e.g., baleen whales) incur a greater relative energetic cost for mild behavioral responses as compared to the most extreme observed response for larger odontocetes (e.g., beaked whales). Energetic costs are more sensitive to lost feeding opportunities than ... : This dataset contains three types of data. Prey: the log mean and log standard deviation of energy acquired per feeding event (kJ). For single prey item foragers (toothed whales; odontoceti), this is the mean and standard deviation of the logged energy content of prey (kJ), weighted by diet proportion. For bulk filter feeders (rorqual whales; Balaenopteridae), this is the mean and standard deviation of the logged biomass density (kg m-3) of krill swarms in the vicinity of feeding whales, multiplied by predator engulfment capacity (m3) and prey energy density (kJ kg-1). Feeding: the number of feeding events in an hour by tagged cetaceans. Each row corresponds to one hour of a tag deployment. Morphology: the representative length (m) and mass (kg) of cetacean species used in the analysis. ... |
