Weeks hunted and caught 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 fresh new suggest number of bobcats create a year of the candidates is actually 0.forty five (variety = 0.22–0.72) (Table step 1) and you may presented zero obvious development throughout the years (roentgen = -0.ten, P = 0.76). Contrary to our theory, there’s zero difference in exactly how many bobcats put-out ranging from successful and ineffective hunters (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). The fresh annual quantity of bobcats released of the hunters 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 variety

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%).

Huntsman and trapper CPUE all over the many years wasn’t synchronised which have bobcat wealth (roentgen = 0.38, P = 0.09 and you may roentgen = 0.thirty two, P = 0.16, respectively). However, in the two time periods we examined (1993–2002 and you may 2003–2014), the new correlations anywhere between huntsman and you will trapper CPUE and you will bobcat abundance was the coordinated (|r| ? 0.63, P ? 0.05) with the exception of huntsman CPUE while in the 1993–2002 which had a marginal matchmaking (r = 0.54, P = 0.11, Table dos).
