Table 6 and Fig. 3 display the percentage of puma locations in each parcel size class for
daytime versus nighttime locations. Paired Student’s t-tests indicated that nighttime puma
locations (21:00 hrs to 05:00 hrs PST) occurred more often in the smaller parcel size
classes, 0 to 5.00 acres, 5.01 to 10.00 acres, and 10.01 to 20.00 acres, than did daytime
locations (09:00 hrs to 17:00 hrs PST) (t = 2.657, df = 5, p = 0.045; t = 3.719, df = 5,
p = 0.014; t = 4.604, df = 5, p = 0.006). Nighttime locations occurred less often in the 2
largest parcel size classes, 40.01 to 100.00 acres and 100.00 + acres, than did daytime
puma locations (t = 6.482, df = 5, p = 0.001; t = 4.795, df = 5, p = 0.005). Puma use of
20.01- to 40.00-acre parcels did not differ between day and night (t = 1.387, df = 5,
p = 0.224).
Table 6. Percent day vs. night use of property parcel size classes by GPS-collared pumas
in developed rural zone of California’s Western Sierra Nevada, 2002-2006. Values
presented as percent day/percent night use. Day use: percent puma collar locations in
parcel size class during 09:00 hrs -17:00 hrs. Night use: percent puma collar locations in
parcel size class during 21:00 hrs -05:00 hrs.
