Weeks hunted and you will 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 released
The fresh imply number of bobcats put out a-year by the seekers try 0.forty five (assortment = 0.22–0.72) (Desk step one) and you may presented no clear development over the years (r = -0.10, P = 0.76). In contrast to our hypothesis, there was no difference in the amount of bobcats released ranging from successful and unproductive hunters (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). The fresh yearly quantity of bobcats put-out by the candidates wasn’t coordinated which have bobcat wealth (roentgen = -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-efforts 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).
Hunter and trapper CPUE all over all the many years was not synchronised which have bobcat wealth (roentgen = 0.38, P = 0.09 and r = 0.32, P = 0.sixteen want STD Sites dating, respectively). But in the two-time attacks we checked (1993–2002 and you may 2003–2014), the fresh correlations between huntsman and you can trapper CPUE and you may bobcat wealth was basically all coordinated (|r| ? 0.63, P ? 0.05) except for hunter CPUE during 1993–2002 which in fact had a limited matchmaking (r = 0.54, P = 0.11, Dining table 2). Brand new relationships between CPUE and you can abundance was self-confident while in the 1993–2002 even though the 95% CI to own ? had been large and you can overlapped step 1.0 both for huntsman and you may trapper CPUE (Fig step 3). 0 indicating CPUE declined more rapidly within straight down abundances (Fig step 3). Hunter CPUE met with the most effective experience of bobcat variety (Roentgen 2 = 0.73, Dining table 2).
