Days hunted and 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 new indicate number of bobcats create a-year by seekers was 0.45 (range = 0.22–0.72) (Dining table step 1) and you will exhibited no obvious trend over the years (r = -0.ten, P = 0.76). Contrary to the theory, there is certainly zero difference between exactly how many bobcats released between winning and you may unproductive hunters (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). The fresh annual level of bobcats put-out of the candidates wasn’t coordinated with bobcat wealth (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 https://datingranking.net/local-hookup/milwaukee/ = 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 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 you may trapper CPUE around the all ages was not correlated with bobcat abundance (r = 0.38, P = 0.09 and r = 0.thirty-two, P = 0.sixteen, respectively). But in the two-time symptoms we checked out (1993–2002 and you can 2003–2014), brand new correlations ranging from hunter and you can trapper CPUE and you can bobcat variety was indeed most of the coordinated (|r| ? 0.63, P ? 0.05) apart from hunter CPUE throughout 1993–2002 which had a marginal matchmaking (roentgen = 0.54, P = 0.eleven, Desk dos). The latest matchmaking anywhere between CPUE and you will abundance was indeed confident throughout 1993–2002 while the 95% CI to own ? was greater and overlapped step 1.0 for hunter and trapper CPUE (Fig 3). 0 showing CPUE refused quicker within all the way down abundances (Fig step 3). Huntsman CPUE encountered the most powerful reference to bobcat abundance (Roentgen dos = 0.73, Dining table dos).
