    • Cultural turnover among Galápagos sperm whales 

      Cantor, Mauricio; Whitehead, Hal; Gero, Shane; Rendell, Luke Edward (2016-10) - Journal article
      While populations may wax and wane, it is rare for an entire population to be replaced by a completely different set of individuals. We document the large-scale relocation of cultural groups of sperm whale off the Galápagos ...
    • Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis 

      Harris, Catriona M; Sadykova, Dinara; De Ruiter, Stacy Lynn; Tyack, Peter Lloyd; Miller, Patrick; Kvadsheim, Petter; Lam, Frans-Peter; Thomas, Len (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 ...
    • Influence of natural factors and anthropogenic stressors on sperm whale foraging effort and success at high latitudes 

      Isojunno, Saana (University of St Andrews, 2015-06) - Thesis
      Behavioural responses can reveal important fitness trade-offs and ecological traps in evolutionarily novel contexts created by anthropogenic stimuli, and are of increasing conservation concern due to possible links to ...
    • Predictive models of cetacean distributions off the west coast of Scotland 

      Embling, Clare B. (University of St Andrews, 2008-11-27) - Thesis
      The main purpose of this study was to produce and test the reliability of predictive models of cetacean distributions off the west coast of Scotland. Passive acoustic and visual surveys were carried out from platforms of ...
    • Spatial ecology of marine top predators 

      Jones, Esther Lane (University of St Andrews, 2017-06-21) - Thesis
      Species distribution maps can provide important information to focus conservation efforts and enable spatial management of human activities. Two sympatric marine predators, grey seals (Halichoerus grypus) and harbour seals ...
    • Sperm whale diet variation by sex, location, year, social group and clan : Evidence from stable isotopes 

      Marcoux, M; Whitehead, H; Rendell, Luke Edward (2007) - Journal article
      We studied the diet of sperm whales Physeter macrocephalus by measuring carbon and nitrogen isotope ratios in 106 sloughed skin samples and 10 squid beaks (Histioteuthidae spp.), the latter collected from sperm whale ...
    • Sperm whales reduce foraging effort during exposure to 1-2 kH z sonar and killer whale sounds 

      Isojunno, Saana; Curé, Charlotte; Kvadsheim, Petter Helgevold; Lam, Frans-Peter Alexander; Tyack, Peter Lloyd; Wensveen, Paul Jacobus; Miller, Patrick James O'Malley (2016-02-08) - Journal article
      The time and energetic costs of behavioral responses to incidental and experimental sonar exposures, as well as control stimuli, were quantified using hidden state analysis of time series of acoustic and movement data ...
