    • Double-observer line transect surveys with Markov-modulated Poisson process models for overdispersed animal availability 

      Borchers, David Louis; Langrock, Roland (2015-12) - Journal article
      We develop maximum likelihood methods for line transect surveys in which animals go undetected at distance zero, either because they are stochastically unavailable while within view or because they are missed when they are ...
    • A general framework for animal density estimation from acoustic detections across a fixed microphone array 

      Stevenson, B.C.; Borchers, D.L.; Altwegg, R.; Swift, R.J.; Gillespie, D.M.; Measey, G.J. (2015-01) - Journal article
      Acoustic monitoring can be an efficient, cheap, non-invasive alternative to physical trapping of individuals. Spatially explicit capture-recapture (SECR) methods have been proposed to estimate calling animal abundance and ...
    • Modelling group dynamic animal movement 

      Langrock, Roland; Hopcraft, Grant; Blackwell, Paul; Goodall, Victoria; King, Ruth; Niu, Mu; Patterson, Toby; Pedersen, Martin; Skarin, Anna; Schick, Robert Schilling (2014-02) - Journal article
      1). Group dynamics are a fundamental aspect of many species' movements. The need to adequately model individuals' interactions with other group members has been recognized, particularly in order to differentiate the role ...
