    • Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis 

      Harris, Catriona M.; Sadykova, Dinara; DeRuiter, Stacy; Tyack, Peter L.; Miller, Patrick J.O.; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Thomas, Len (2015)
      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 ...

    • Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales 

      Miller, Patrick J.O.; Antunes, Ricardo; Wensveen, Paul; Samarra, Filipa I. P.; Alves, Ana Catarina; Tyack, Peter L.; Kvadsheim, Petter Helgevold; Kleivane, Lars; Lam, Frans-Peter A.; Ainslie, Michael A; Thomas, Len (2014)
      Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal ...

    • High thresholds for avoidance of sonar by free-ranging long-finned pilot whales (Globicephala melas) 

      Antunes, Ricardo; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Tyack, Peter L.; Thomas, Len; Wensveen, Paul J.; Miller, Patrick James O'Malley (2014)
      The potential effects of exposing marine mammals to military sonar is a current concern. Dose–response relationships are useful for predicting potential environmental impacts of specific operations. To reveal behavioral ...

    • Marine mammals and sonar: dose-response studies, the risk-disturbance hypothesis and the role of exposure context 

      Harris, Catriona; Thomas, Len; Falcone, Erin; Hildebrand, Jon; Houser, Dorian; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick James O'Malley; Moretti, David; Read, Andrew; Slabbekoorn, Hans; Southall, Brandon L.; Tyack, Peter Lloyd; Wartzok, D.; Janik, V. M. (2017)
      Marine mammals may be negatively affected by anthropogenic noise. Behavioural response studies (BRS) aim to establish a relationship between noise exposure conditions (dose) from a potential stressor and associated behavioural ...
