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 released
New imply number of bobcats put out annually by seekers are 0.45 (variety = 0.22–0.72) (Table 1) and you can demonstrated zero obvious pattern through the years (roentgen = -0.10, P = 0.76). In comparison to all of our hypothesis, there is no difference between the number of bobcats released anywhere between profitable and you will ineffective candidates (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). The latest yearly number of bobcats put out because of the seekers was not correlated with bobcat wealth (r = -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-energy metrics and 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).
Hunter and you can trapper CPUE all over the many years was not synchronised that have bobcat wealth (roentgen = 0.38, P = 0.09 and roentgen = 0.32, P = 0.sixteen, respectively). But for the two time attacks we tested (1993–2002 and 2003–2014), the fresh correlations ranging from hunter and you will trapper CPUE and bobcat variety was every coordinated (|r| ? 0.63, P ? 0.05) except for hunter CPUE while in the 1993–2002 which had a marginal matchmaking (r = 0.54, P = 0.11, Table dos). Brand new relationships anywhere between CPUE and you may abundance were confident throughout the 1993–2002 even though the 95% CI to have ? had been wide and overlapped step 1.0 for both huntsman and you can trapper CPUE (Fig step three). 0 appearing CPUE refused more rapidly in the lower abundances (Fig step three). Hunter CPUE encountered the most powerful reference Little People dating site to bobcat wealth (Roentgen dos = 0.73, Table dos).
Strong traces is actually projected fits out-of linear regression patterns if you find yourself dashed traces try estimated suits away from reduced big axis regression of diary off CPUE/ACPUE up against the log regarding variety. New dependent and independent details had been rescaled of the breaking up by the maximum worthy of.
