  • Animal-Borne Acoustic Transceivers Reveal Patterns of at-Sea Associations in an Upper-Trophic Level Predator 

    Lidgard, Damian C., W. Don Bowen, Ian D. Jonsen, and Sara J. Iverson. 2012. "Animal-Borne Acoustic Transceivers Reveal Patterns of at-Sea Associations in an Upper-Trophic Level Predator." Plos One 7(11): 48962-e48962.
    Satellite telemetry data have substantially increased our understanding of habitat use and foraging behaviour of upper-trophic marine predators, but fall short of providing an understanding of their social behaviour. We ...

  • Inferring Animal Densities from Tracking Data Using Markov Chains 

    Whitehead, Hal, and Ian D. Jonsen. 2013. "Inferring Animal Densities from Tracking Data Using Markov Chains." Plos One 8(4): 60901-e60901.
    The distributions and relative densities of species are keys to ecology. Large amounts of tracking data are being collected on a wide variety of animal species using several methods, especially electronic tags that record ...

  • Sex-specific, seasonal foraging tactics of adult grey seals (Halichoerus grypus) revealed by state-space analysis 

    Breed, Greg A., Ian D. Jonsen, Ransom A. Myers, W. Don Bowen, et al. 2009. "Sex-specific, seasonal foraging tactics of adult grey seals (Halichoerus grypus) revealed by state-space analysis." Ecology 90(11): 3209-3221. Copyright by the Ecological Society of America.
    In many large pelagic animals, observing behavior is limited to observation by radio or satellite telemetry. In many cases, discriminating different behaviors from telemetry data has been a key, but often elusive, goal. ...
