Dynamic multistate site occupancy models to evaluate hypotheses relevant to conservation of Golden Eagles in Denali National Park, Alaska.

摘要: The recent development of multistate site occupancy models offers great opportunities to frame and solve decision problems for conservation that can be viewed in terms occupancy. These have several characteristics (e.g., they account detectability) make them particularly well suited addressing management problems. We applied evaluate hypotheses related the Golden Eagles (Aquila chrysaetos) Denali National Park, Alaska, provided estimates transition probabilities among three states nesting areas (occupied with successful reproduction, occupied unsuccessful unoccupied). Our estimation included effect potential recreational activities (hikers) environmental covariates such as a snowshoe hare (Lepus americanus) index on states. Based most parsimonious model, support hypothesis an human disturbance dynamics was equivocal. There some evidence negatively affected local colonization territories, but there no reproductive performance parameters. In addition, assume positive relationship between reproduction were supported by data. statistical approach we used is useful parameterize then optimal decisions Denali. Although our case interested managing activities, believe should broad class
