Evaluating the effect of measurement error in pairs of 3D bearings in point transect sampling estimates of density
(University of St Andrews, 2018-03-27) - Report,
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)
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 ...
A risk function for behavioral disruption of Blainville’s beaked whales (Mesoplodon densirostris) from mid-frequency active sonar
(2014-01) - Journal article,
There is increasing concern about the potential effects of noise pollution on marine life in the world’s oceans. For marine mammals, anthropogenic sounds may cause behavioral disruption, and this can be quantified using a ...
Spatial variation in maximum dive depth in gray seals in relation to foraging.
(2014-07) - Journal article,
Habitat preference maps are a way of representing animals’ space use in two dimensions. For marine animals, the third dimension is an important aspect of spatial ecology. We used dive data from seven gray seals Halichoerus ...
The effects of acoustic misclassification on cetacean species abundance estimation
(2013-12-25) - Journal article,
To estimate the density or abundance of a cetacean species using acoustic detection data, it is necessary to correctly identify the species that are detected. Developing an automated species classifier with 100% correct ...
Estimating resource acquisition and at-sea body condition of a marine predator
(2013) - Journal article,
(1) Body condition plays a fundamental role in many ecological and evolutionary processes at a variety of scales and across a broad range of animal taxa. An understanding of how body condition changes at fine spatial and ...
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 ...
Density estimation implications of increasing ambient noise on beaked whale click detection and classification
(University of St Andrews, 2010) - Report,
Acoustic based density estimates are being increasingly used. Usually density estimation methods require one to evaluate the eﬀective survey area of the acoustic sensors, or equivalently estimate the mean detection probability ...
An update to the methods in Endangered Species Research 2011 paper "Estimating North Pacific right whale Eubalaena japonica density using passive acoustic cue counting"
(University of St Andrews, 2012) - Report,
A critical review of the literature on population modelling
(University of St Andrews, 2009) - Report,
The 2005 report of the National Research Council’s ‘Committee on Characterizing Biologically Significant Marine Mammal Behavior’ proposed a framework, which they called PCAD - Population Consequences of Acoustic Disturbance, ...
