WebMay 5, 2024 · We include unknown fates in our risk estimates. We found that anthropogenic COD accounted for 0.78–0.85 of 508 marked animals, including poaching and cryptic poaching, which we estimated at 0.51–0.64. Risk of poaching and disappearance was significantly higher during hunting season. WebHere we develop an integrated model combining known-fate and open N-mixture models, allowing the estimation of detection probability, recruitment, and the joint estimation of survival. We demonstrate our approach through both simulations and an applied example using four years of known-fate and pack count data for wolves (Canis lupus).
