Population biology of bottlenose dolphins in the Azores archipelago
(University of St Andrews, 2007-06) - Thesis,
The ranging behaviour, habitat preferences, genetic structure, and demographic parameters of bottlenose dolphins living in the Azores were studied using data collected from 1999 to 2004. Only 44 dolphins out of 966 identified ...
Ecology and conservation of bottlenose dolphins (Tursiops truncatus) in the north-eastern Adriatic Sea
(University of St Andrews, 2007) - Thesis,
Bottlenose dolphins of the Kvarnerić (NE Adriatic Sea) live in an area of increasing
human impact, through tourism and small-scale fisheries. This thesis aimed to assess the
status of the local population and to inform ...
Respiration timing and underwater activity in killer whales (Orcinus orca)
(University of St Andrews, 2015-06-24) - Thesis,
Accurate estimates of energetic requirements of top predators in-situ are essential to improve sustainable marine ecosystems’ management. Yet, obtaining direct energetic measurements of free-ranging cetaceans is unfeasible. ...
Conservation ecology and phylogenetics of the Indus River dolphin (Platanista gangetica minor)
(University of St Andrews, 2012-06-20) - Thesis,
The historical range of the Indus River dolphin has declined by 80% since the 19th
century and has been fragmented into 17 river sections by construction of irrigation
barrages. Dolphin sighting and interview surveys ...
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 ...
Novel methods for species distribution mapping including spatial models in complex regions
(University of St Andrews, 2013-11-05) - Thesis,
Species Distribution Modelling (SDM) plays a key role in a number of biological applications: assessment of temporal trends in distribution, environmental impact assessment and spatial conservation planning. From a statistical ...
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 ...
