Months hunted and you will trapped
Hunters showed a decreasing trend in the number of days hunted over time (r = -0.63, P = 0.0020, Fig 1), but an increasing trend in the number of bobcats chased per day (r = 0.77, P < 0.0001, Fig 1). Contrary to our hypothesis, the number of days hunted did not differ between successful and unsuccessful hunters ( SE; SE; ? = 0.04, P = 0.13).
Trappers exhibited substantial annual variation in the number of days trapped over time, but without a clear trend (r = -0.15, P = 0.52). Trappers who harvested a bobcat used more trap sets than trappers who did not ( SE, SE; ? = 0.17, P < 0.01). The mean number of trap-days also showed an increasing trend (r = 0.52, P = 0.01, Fig 1). Trappers who harvested a bobcat had more trap-days ( SE) than trappers who did not harvest a bobcat ( SE) (? = 0.12, P = 0.04).
Bobcats create
The brand new mean quantity of bobcats put out per year from the candidates is 0.forty-five (range = 0.22–0.72) (Desk step one) and you may presented zero obvious pattern throughout the years (r = -0.ten, P = 0.76). Contrary to the hypothesis, there’s no difference in what amount of bobcats released ranging from profitable and you will unsuccessful seekers (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). The new yearly level of bobcats put-out by candidates wasn’t correlated which have bobcat abundance (r = -0.14, P = 0.65).
The mean number of bobcats released annually by trappers was 0.21 (range = 0.10–0.52) (Table 1) but was not correlated with year (r = 0.49, P = 0.11). Trappers who harvested a bobcat released more bobcats ( SE) than trappers who did not harvest a bobcat ( SE) (? = 2.04, P < 0.0001). The annual number of bobcats released by trappers was not correlated with bobcat abundance (r = -0.45, P = 0.15).
Per-unit-work metrics and you can abundance
The mean CPUE was 0.19 bobcats/day for hunters (range = 0.05–0.42) and 2.10 bobcats/100 trap-days for trappers (range = 0.50–8.07) (Table 1). The mean ACPUE was 0.32 bobcats/day for hunters (range = 0.16–0.54) and 3.64 bobcats/100 trap-days for trappers (range = 1.49–8.61) (Table 1). The coefficient of variation for CPUE and ACPUE was greater for trappers than for hunters (trapper CPUE = 96%, hunter CPUE = 65%, trapper ACPUE = 68%, hunter ACPUE = 36%). All four metrics increased over time (Fig 2) although the strength of the relationship with year varied (hunter CPUE:, r = 0.92, P < 0.01; trapper CPUE: r = 0.73, P = < 0.01; hunter ACPUE: r = 0.82, P = < 0.01; trapper ACPUE: r = 0.66, P = 0.02).
Huntsman and you can trapper CPUE across the all years wasn’t coordinated having bobcat variety (roentgen = 0.38, P = 0.09 and roentgen = 0.thirty-two, P = 0.sixteen, respectively). However, when you look at the two time symptoms i tested (1993–2002 and 2003–2014), the fresh new correlations ranging from huntsman and trapper CPUE and bobcat wealth were every correlated (|r| ? 0.63, P ? 0.05) with the exception of huntsman CPUE throughout 1993–2002 which in fact had a limited relationships (r = 0.54, P = 0.11, Dining table 2). Brand new matchmaking between CPUE and you can variety was positive during the 1993–2002 while the 95% CI for ? was indeed greater and overlapped 1.0 for both hunter and you can trapper CPUE (Fig step three). 0 demonstrating CPUE denied faster on all the way down abundances (Fig 3). Huntsman CPUE met with the strongest connection with bobcat variety (Roentgen 2 https://datingranking.net/senior-dating-sites/ = 0.73, Dining table 2).
