The foraging behaviour and body condition of northern bottlenose whales (Hyperoodon ampullatus)
(University of St Andrews, 2020-12-01) - ThesisDespite foraging being critical for survival, characterising foraging behaviour in marine animals is inherently challenging. Found in deep offshore habitats, beaked whales are the least known cetacean family, whose foraging ... -
Acoustic deep scattering layers as dynamic prey landscapes for air-breathing deep-diving Antarctic predators
(University of St Andrews, 2020-12-01) - ThesisThis PhD addresses the central hypothesis that acoustic Deep Scattering Layers (DSLs) are a prey landscape for deep-diving air-breathing Southern Ocean predators. In the open ocean, mesopelagic fish (including myctophids), ... -
Passive acoustic monitoring of harbour porpoise behaviour, distribution and density in tidal rapid habitats
(University of St Andrews, 2020-12-01) - ThesisToothed whales produce regular echolocation clicks to sense their surroundings and hunt. These clicks can be detected on hydrophones allowing researchers to study and monitor animals, a methodology known as passive acoustic ... -
Characterisation of organic osmolytes and biomarkers of smoltification in the Atlantic salmon (Salmo salar)
(University of St Andrews, 2020-12-01) - ThesisAtlantic salmon are an economically important species, particularly in Scotland. The aquaculture of this species is complicated by its anadromous life cycle, requiring transfer to seawater. Smoltification is a complex ... -
Informing the conservation and restoration of a keystone species : the larval behaviour of the European oyster Ostrea edulis
(University of St Andrews, 2020-06-23) - ThesisThe European oyster Ostrea edulis is a keystone species that is internationally recognised as ‘threatened and declining’ in the North-East Atlantic and several nations have adopted strategies for its conservation and ...
