Table 2 Step selection analysis terms and descriptions for Wisconsin white-tailed deer
From: Agricultural land use shapes dispersal in white-tailed deer (Odocoileus virginianus)
Term | Description or prediction |
|---|---|
Step length | Estimator for scale parameter of gamma step-length distribution |
log(Step length) | Estimator for shape parameter of gamma step-length distribution |
cosine(Turning angle) | Estimator for concentration parameter of von Mises turning angle distribution |
Agricultural (end of step) | Avoidance of agricultural land use during dispersal movements |
Elevation + Elevation2 | Selection for intermediate elevation |
Distance to rivers/streams | Avoidance of greater distance from nearest river/stream |
Intersection with roads | Avoidance of road crossings |
Agricultural (start): Step length | More variable step lengths when steps initiate in agricultural land use |
Agricultural (start): log(Step length) | Longer step lengths when steps initiate in agricultural land use |
Agricultural (start): cosine(Turning angle) | More concentrated turning angles (i.e., less variation from moving straight ahead) when steps initiate in agricultural land use |
