    • Estimating spatially variable and density-dependent survival using open-population spatial capture–recapturemodels 

      Milleret, Cyril Pierre; Dey, Soumen; Dupont, Pierre; Brøseth, Henrik; Turek, Daniel; Bischof, Richard (Peer reviewed; Journal article, 2022)
      Open-population spatial capture–recapture (OPSCR) models use the spatialinformation contained in individual detections collected over multiple consec-utive occasions to estimate not only occasion-specific density, but ...

    • A flexible and efficient Bayesian implementation of point process models for spatial capture‐recapture data 

      Wei, Zhang; Chipperfield, Joseph; Illian, Janine; Dupont, Pierre; Milleret, Cyril Pierre; de Valpine, Perry; Bischof, Richard (Peer reviewed; Journal article, 2022)
      Spatial capture–recapture (SCR) is now routinely used for estimating abundance and density of wildlife populations. A standard SCR model includes sub-models for the distribution of individual activity centers (ACs) and for ...
