Simulated HSF location data for demonstrating UHC plots
Description
Simulated HSF location data for demonstrating UHC plots
Usage
uhc_hsf_locs
Format
A data.frame
with 2000 rows and 2 variables:
- x
x-coordinate in UTM Zone 12 (EPSG: 32612)
- y
Y-coordinate in UTM Zone 12 (EPSG: 32612)
These data were simulated assuming an ordinary habitat selection function (HSF), i.e., all points are independent rather than arising from an underlying movement model.
True parameter values are:
-
forage
= log(5)/500 (resource) -
temp^2
= -1 * log(2)/36 (condition; quadratic term) -
temp
= (log(2)/36) * 26 (condition; linear term) -
pred
= log(0.25)/5 (risk) -
cover == "forest"
= log(2) (grassland is intercept) -
cover == "wetland"
= log(1/2) (grassland is intercept)
Note: temp
is modeled as a quadratic term, with the strongest selection
occurring at 13 °C and all other temperatures less selected.
Note: dist_to_water
, dist_to_cent
, and rand
have no real effect
on our animal's selection and are included for demonstration purposes.
