lynx_data

This table contains lynx steps associated with habitat variables and temporal variables that were used to build a step selection function model for lynx. The table is divided into used (actual) lynx steps and random steps in a ratio of 1:10 (column "use"). The random steps match to their corresponding location id in the used steps. Swisstopo in the column headers refers to the source of the environmental variables. Hum_indx is a composite of road_dist and house density. Prey_avail are the values of a deer RSF, which was used as a proxy for prey availability. Dist2 refers to the step length (distance between the previous and current location in meters). The 8 temporal variables are time harmonics of a Fourier transform for time of day (tsin, tcos, tsin2, tcos2; period of 24) and day of year(ytsin, ytcos, ytsin2, ytcos2; period of 365). All habitat variables were measured at the beginning of a step except for “hum_indx_loc2”, which was measured at the beginning of a step. All continuous variables in this table are mean centered and standardized to a SD=1. For information on the raw data or for R-code used to run the models please contact the data owner.
