Short first click intervals in echolocation trains of three species of deep diving odontocetes
(2017-02) - Journal article,
All odontocetes produce echolocation clicks as part of their vocal repertoire. In this paper we analysed inter-click-intervals in recordings from suction cup tags with a focus on the first inter-click interval of each click ...
Whistle characteristics and daytime dive behavior in pantropical spotted dolphins (Stenella attenuata) in Hawai‘i measured using digital acoustic recording tags (DTAGs)
(2016-07-19) - Journal article,
This study characterizes daytime acoustic and dive behavior of pantropical spotted dolphins (Stenella attenuata) in Hawai‘i using 14.58 h of data collected from five deployments of digital acoustic recording tags (DTAG3) ...
The significance of respiration timing in the energetics estimates of free-ranging killer whales (Orcinus orca)
(2016-07) - Journal article,
Respiration rate has been used as an indicator of metabolic rates and associated cost-of-transport (COT) of free-ranging cetaceans, discounting potential respiration-by-respiration variation in O2 uptake. To investigate ...
Acoustic deterrent devices to prevent pinniped depredation : efficiency, conservation concerns and possible solutions
(2013-10-31) - Journal article,
Acoustic deterrent devices (ADDs) to prevent pinniped predation on fish farms and fisheries are widely used, but show highly varying success. Recently, ADDs have also been highlighted as a conservation concern due to their ...
Naval sonar disrupts foraging behaviour in humpback whales
(2016-12-29) - Journal article,
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, ...
A simulation approach to assessing environmental risk of sound exposure to marine mammals
(2017-04) - Journal article,
Intense underwater sounds caused by military sonar, seismic surveys, and pile driving can harm acoustically sensitive marine mammals. Many jurisdictions require such activities to undergo marine mammal impact assessments ...
Vessel noise affects beaked whale behavior : Results of a dedicated acoustic response study
(2012-08-03) - Journal article,
Some beaked whale species are susceptible to the detrimental effects of anthropogenic noise. Most studies have concentrated on the effects of military sonar, but other forms of acoustic disturbance (e.g. shipping noise) ...
A description of LATTE outputs
(University of St Andrews, 2015-10-30) - Report,
Body density and diving gas volume of the northern bottlenose whale (Hyperoodon ampullatus)
(2016-08-17) - Journal article,
Diving lung volume and tissue density, reflecting lipid store volume, are important physiological parameters that have only been estimated for a few breath-hold diving species. We fitted 12 northern bottlenose whales with ...
Dynamic habitat corridors for marine predators : intensive use of a coastal channel by harbour seals is modulated by tidal currents
(2016-12) - Journal article,
Previous studies have found that predators utilise habitat corridors to ambush prey moving through them. In the marine environment, coastal channels effectively act as habitat corridors for prey movements, and sightings ...
