日時: 2013 年 9 月 4 日 (水) 13:15 から 1 時間程度 会場: 北海道大学・環境科学院 (http://www.ees.hokudai.ac.jp) D101 教室 講演者: Bryan Manly and Lyman McDonald (Western EcoSystems Technology, Inc.) 演題: Estimating Habitat Selection When the GPS Fix Success Rate is less than 100% 要旨: This presentation is about situations where the plan is to detect a radio-tagged animal at fixed intervals of time (e.g., every 6 hours) so that its location is known in the area occupied and, based on this information, estimate how the animal selects habitat based on the available habitat and the detected locations. For example, if the area of interest is divided up into square quadrats then given the quadrat location of the animal for one detection it is possible to estimate a function that gives the probability that the animal will be seen next at any of the other quadrats in the area based on the habitats in the quadrats and the distance from the first location. This would be relatively easy to model if the animal is always detected when it is supposed to be. If this is not the case then the probability of detection is likely to depend on the habitat. We therefore propose a method for estimating a resource selection function that says how the animal prefers different habitats, and also estimating a detection function that says how the probability of detection depends on the habitat as well.
