Mixture models for distance sampling detection functions
(2015-03-20) - Journal article,
We present a new class of models for the detection function in distance sampling surveys of wildlife populations, based on finite mixtures of simple parametric key functions such as the half-normal. The models share many ...
A path reconstruction method integrating dead-reckoning and position fixes applied to humpback whales
(2015-09-21) - Journal article,
BACKGROUND: Detailed information about animal location and movement is often crucial in studies of natural behaviour and how animals respond to anthropogenic activities. Dead-reckoning can be used to infer such detailed ...
Efficient abstracting of dive profiles using a broken-stick model
(2015-03) - Journal article,
For diving animals, animal-borne sensors are used to collect time-depth information for studying behaviour, ranging patterns and foraging ecology. Often, this information needs to be compressed for storage or transmission. ...
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 ...
Nested row-column designs for near-factorial experiments with two treatment factors and one control treatment
(2015-10) - Journal article,
This paper presents some methods of designing experiments in a block design with nested rows and columns. The treatments consist of all combinations of levels of two treatment factors, with an additional control treatment.
The effect of animal movement on line transect estimates of abundance
(2015-03-23) - Journal article,
Line transect sampling is a distance sampling method for estimating the abundance of wild animal populations. One key assumption of this method is that all animals are detected at their initial location. Animal movement ...
Impacts of anthropogenic noise on marine life : publication patterns, new discoveries, and future directions in research and management
(2015-10) - Journal article,
Anthropogenic underwater noise is now recognized as a world-wide problem, and recent studies have shown a broad range of negative effects in a variety of taxa. Underwater noise from shipping is increasingly recognized as ...
Status and future of research on the behavioural responses of marine mammals to U.S. Navy sonar
(University of St Andrews, 2015) - Report,
A review of the status and future of research into behavioral responses of marine mammals to naval sonar exposure was undertaken to evaluate the return on investment of current US Navy funded programs, identify the data ...
Higher biodiversity is required to sustain multiple ecosystem processes across temperature regimes
(2015-01) - Journal article,
Biodiversity loss is occurring rapidly worldwide, yet it is uncertain whether few or many species are required to sustain ecosystem functioning in the face of environmental change. The importance of biodiversity might be ...
Inter-annual and seasonal trends in cetacean distribution, density and abundance off southern California
(2015-02) - Journal article,
Trends in cetacean density and distribution off southern California were assessed through visual line-transect surveys during thirty-seven California Cooperative Oceanic Fisheries Investigations (CalCOFI) cruises from July ...
