Using short-term measures of behaviour to estimate long-term fitness of southern elephant seals.
(2014-01-27) - Journal article,
Environmental changes (a type of disturbance) are altering the habitat of southern elephant seals Mirounga leonina, an apex marine predator in the Southern Ocean. As a result, individuals may shift their behaviour, spending ...
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 ...
Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales
(2014-02) - Journal article,
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 ...
First direct measurements of behavioural responses by Cuvier's beaked whales to mid-frequency active sonar
(2013) - Journal article,
Most marine mammal strandings coincident with naval sonar exercises have involved Cuvier's beaked whales (Ziphius cavirostris). We recorded animal movement and acoustic data on two tagged Ziphius and obtained the first ...
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 ...
Using accelerometers to determine the calling behavior of tagged baleen whales
(2014-07-15) - Journal article,
Low-frequency acoustic signals generated by baleen whales can propagate over vast distances, making the assignment of calls to specific individuals problematic. Here, we report the novel use of acoustic recording tags ...
