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 ...
Echolocation : clicking for supper
(2015-04-29) - Journal article,
When close to prey, porpoises actively widen their sonar beam, which may make it harder for the prey to escape.
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) ...
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, ...
Acoustic playback experiments to study behavioral responses of free-ranging marine animals to anthropogenic sound
(2009-12-03) - Journal article,
Growing concern about the effects of anthropogenic sound on marine life has highlighted the need for empirical methods to study behavioral responses of marine animals to specific acoustic exposures. Some effects have been ...
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) ...
Changes in dive behaviour during naval sonar exposure in killer whales, long-finned pilot whales, and sperm whales.
(2012-10-11) - Journal article,
Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ...
Deadly diving? Physiological and behavioural management of decompression stress in diving mammals
(2012-03-22) - Journal item,
Decompression sickness (DCS; 'the bends') is a disease associated with gas uptake at pressure. The basic pathology and cause are relatively well known to human divers. Breath-hold diving marine mammals were thought to be ...
Estimating animal population density using passive acoustics
(2013-05) - Journal article,
Reliable estimation of the size or density of wild animal populations is very important for effective wildlife management, conservation and ecology. Currently, the most widely used methods for obtaining such estimates ...
