Date_Time: Date and time of GPS location (m/d/y h:m:s)
BearID: First five digits are the unique bear ID, last two digits are the year (20XX)
DistToROAD: distance (m) to the nearest roadway
MAXHRpt: maximum heart rate (beats per minute) recorded by the cardiac biologger during the period spanning 10 min prior-10 min after the GPS location 
AgUrb: if = 1; GPS location either in agriculture (see manuscript for details) or developed landcover type; other landcover (= 0) 
MOVERATE: rate of movement between subsequent bear GPS-locations  (distance [m]/ time [mins]; see note above)
