Naval sonar disrupts foraging in humpback whales
(2016)
Modern long-range naval sonars are a potential disturbance for marine mammals and can cause disruption of feeding in cetaceans. We examined the lunge-feeding behaviour of humpback whales Megaptera novaeangliae before, ...
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 ...
Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale
(2015)
Anti-predator strategies are often defined as ‘flight’ or ‘fight’, based upon prey anatomical adaptations for size, morphology and weapons, as well as observed behaviours in the presence of predators. The humpback whale ...
Sperm whales reduce foraging effort during exposure to 1-2 kH z sonar and killer whale sounds
(2016)
The time and energetic costs of behavioral responses to incidental and experimental sonar exposures, as well as control stimuli, were quantified using hidden state analysis of time series of acoustic and movement data ...
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 ...
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 ...
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 ...
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 ...
Northern bottlenose whales in a pristine environment respond strongly to close and distant navy sonar signals
(2019-03-20)
Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant ...
Breathing patterns indicate cost of exercise during diving and response to experimental sound exposures in long-finned pilot whales
(2018)
Air-breathing marine predators that target sub-surface prey have to balance the energetic benefit of foraging against the time, energetic and physiological costs of diving. Here we use on-animal data loggers to assess ...
