Designing a shipboard line transect survey to estimate cetacean abundance off the Azores Archipelago, Portugal
(2008) - Thesis,
Management schemes dedicated to the conservation of wildlife populations rely on the effective monitoring of population size, and this requires the accurate and precise estimation of abundance. The accuracy and precision ...
Behavioural changes of a long-ranging diver in response to oceanographic conditions
(2007) - Thesis,
The development of an animal-borne instrument that can record oceanographic measurements (CTD-SRDL) has enabled the collection of oceanographic data at a scale relevant to the counterpart behavioural data, both in time and ...
Assessing and correcting for the effects of species misclassification during passive acoustic surveys of cetaceans
(University of St Andrews, 2013-11-29) - Thesis,
In conservation ecology, abundance estimates are an important factor from which management decisions are based. Methods to estimate abundance of cetaceans from visual detections are largely developed, whereas parallel ...
Investigating the surfacing and diving behaviour and availability of long-finned pilot whales and quantifying the effects of anthropogenic sound on density and strandings of cetaceans in the northeast Atlantic
(University of St Andrews, 2014-06-26) - Thesis,
The size and trend of a population is fundamental to the assessment of its conservation status, yet cetacean abundance data are often biased and lack statistical power to detect trends. As a result, the conservation status ...
Density estimation and time trend analysis of large herbivores in Nagarhole, India
(2005) - Thesis,
Density estimates for six large herbivore species were obtained through analysis of line transect data from Nagarhole National Park, south-western India, collected between 1989 and 2000. These species were Chital (Axis ...
Estimating whale abundance using sparse hydrophone arrays
(University of St Andrews, 2012-06-20) - Thesis,
Passive acoustic monitoring has been used to investigate many aspects of marine mammal ecology, although methods to estimate absolute abundance and density using acoustic data have only been developed in recent years. The ...
Detecting, assessing, and mitigating the effects of naval sonar on cetaceans
(University of St Andrews, 2016-04-14) - Thesis,
Effective management of the potential environmental impacts of naval sonar requires quantitative data on the behaviour and hearing physiology of cetaceans. Here, novel experimental and analytical methods were used to obtain ...
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, ...
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 ...
Annual report on the implementation of Council Regulation (EC) No 812/2004 during 2014
(European Commission, 2015-06-01) - Report,
