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 ...
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 ...
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) ...
Sound production and associated behavior of tagged fin whales (Balaenoptera physalus) in the Southern California Bight
(2015-08-03) - Journal article,
Background: For marine animals, acoustic communication is critical for many life functions, yet individual calling behavior is poorly understood for most large whale species. These topics are important for understanding ...
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 ...
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.
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, ...
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 ...
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 ...
