Days hunted and you can swept up
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 put-out
The newest imply level of bobcats put out per year from the seekers is 0.forty five (range = 0.22–0.72) (Table step one) and you can exhibited zero obvious development through the years (r = -0.10, P = 0.76). In contrast to the hypothesis, discover no difference in the amount of bobcats put-out ranging from successful and you will unsuccessful candidates (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). This new yearly amount of bobcats released by the seekers wasn’t correlated which have bobcat wealth (roentgen = -0.fourteen, 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 will wealth
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 around the all years wasn’t correlated having bobcat abundance (roentgen = 0.38, P = 0.09 and you can r = 0.thirty two, P = 0.16, respectively). However, inside the two time episodes we examined (1993–2002 and you may 2003–2014), this new correlations ranging from huntsman and you can best dating sites for Music singles trapper CPUE and bobcat wealth was in fact all synchronised (|r| ? 0.63, P ? 0.05) apart from huntsman CPUE throughout 1993–2002 which in fact had a marginal relationships (roentgen = 0.54, P = 0.11, Dining table 2). New matchmaking anywhere between CPUE and you may abundance was indeed confident throughout 1993–2002 although the 95% CI to possess ? have been greater and you may overlapped 1.0 for both huntsman and you will trapper CPUE (Fig step three). 0 demonstrating CPUE rejected quicker at the lower abundances (Fig step three). Huntsman CPUE had the most effective connection with bobcat variety (Roentgen dos = 0.73, Desk dos).
Strong traces are estimated matches of linear regression patterns if you find yourself dashed contours was projected matches out of smaller biggest axis regression of diary away from CPUE/ACPUE contrary to the journal of wealth.
