Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015)
Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
Modeling Effectiveness of Gradual Increases in Source Level to Mitigate Effects of Sonar on Marine Mammals
(2014)
Ramp-up or soft-start procedures (i.e., gradual increase in the source level) are used to mitigate the effect of sonar sound on marine mammals, although no one to date has tested whether ramp-up procedures are effective ...
Pilot Whales Attracted to Killer Whale Sounds: Acoustically-Mediated Interspecific Interactions in Cetaceans
(2012)
In cetaceans’ communities, interactions between individuals of different species are often observed in the wild. Yet, due to methodological and technical challenges very little is known about the mediation of these ...
Disturbance-specific social responses in long-finned pilot whales, Globicephala melas
(2016)
Social interactions among animals can influence their response to disturbance. We investigated responses of long-finned pilot whales to killer whale sound playbacks and two anthropogenic sources of disturbance: tagging ...
Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales
(2014)
Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal ...
Responses of male sperm whales (Physeter macrocephalus) to killer whale sounds: implications for anti-predator strategies
(2013)
Interactions between individuals of different cetacean species are often observed in the wild. Killer whales (Orcinus orca) can be potential predators of many other cetaceans, and the interception of their vocalizations ...
Biological significance of sperm whale responses to sonar: Comparison with anti-predator responses
(2016)
A key issue when investigating effects of anthropogenic noise on cetacean behavior is to identify the biological significance of the responses. Predator presence can be considered a natural high-level disturbance stimulus ...
The social context of individual foraging behaviour in long-finned pilot whales (Globicephala melas)
(2014)
Long-finned pilot whales (Globicephala melas) are highly social cetaceans that live in matrilineal groups and acquire their prey during deep foraging dives. We tagged individual pilot whales to record their diving behaviour. ...
How man-made interference might cause gas bubble emboli in deep diving whales
(2014)
Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals. Necropsy results of the stranded ...
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
(2015)
Although northern bottlenose whales were the most heavily hunted beaked whale, we have little information about this species in its remote habitat of the North Atlantic Ocean. Underwater anthropogenic noise and disruption ...
