A 3D stereo camera system for precisely positioning animals in space and time
(2015-04) - Journal article,
Here, we describe a portable stereo camera system that integrates a GPS receiver, an attitude sensor and 3D stereo photogrammetry to rapidly estimate the position of multiple animals in space and time. We demonstrate the ...
Blue whales respond to simulated mid-frequency military sonar
(2013) - Journal article,
Mid-frequency military (1–10 kHz) sonars have been associated with lethal mass strandings of deep-diving toothed whales, but the effects on endangered baleen whale species are virtually unknown. Here, we used controlled ...
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.
The evolutionary roots of creativity : mechanisms and motivations
(2015-03) - Journal article,
We consider the evolution of cognition and the emergence of creative behaviour, in relation to vocal communication. We address two key questions: (i) what cognitive and/or social mechanisms have evolved that afford aspects ...
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 ...
Estimated tissue and blood N2 levels and risk of in vivo bubble formation in deep-, intermediate- and shallow diving toothed whales during exposure to naval sonar.
(2012-05-10) - Journal article,
Naval sonar has been accused of causing whale stranding by a mechanism which increases formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased risk of decompression sickness (DCS), ...
The challenges of analyzing behavioral response study data : an overview of the MOCHA (Multi-study OCean acoustics Human effects Analysis) project
(Springer Science and Business Media, 2016) - Conference item,
This paper describes the MOCHA project which aims to develop novel approaches for the analysis of data collected during Behavioral Response Studies (BRSs). BRSs are experiments aimed at directly quantifying the effects of ...
Vocal Learning and Auditory-Vocal Feedback
(Springer, 2016) - Book item,
Vocal learning is usually studied in songbirds and humans, species that can form auditory templates by listening to acoustic models and then learn to vocalize to match the template. Most other species are thought to develop ...
Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015-11-20) - Journal article,
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 ...
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 ...
