The relationships between CPUE and abundance were negative during 2003–2014 and the 95% CI for ? were Months hunted and you may 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 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 Bobcats put out Brand new indicate number of bobcats put-out a year by seekers try 0.forty five (assortment = 0.22–0.72) (Desk step 1) and you can demonstrated no clear pattern through the years (r = -0.10, P = 0.76). In comparison to the theory, you will find no difference in what amount of bobcats put-out between effective and you may ineffective seekers (successful: SE; unsuccessful: SE) (? = 0.20, P = 0.14). The brand new yearly level of bobcats create by the hunters was not correlated which have bobcat abundance (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 Per-unit-efforts metrics and you can 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 Hunter and you can trapper CPUE round the all the ages wasn’t synchronised which have bobcat abundance (r = 0.38, P = 0.09 and you may roentgen = 0.thirty-two, P = 0.16, respectively). But for the two time periods i checked-out (1993–2002 and 2003–2014), this new correlations between huntsman and trapper CPUE and you will bobcat abundance have been the correlated (|r| ? 0.63, P ? 0.05) except for hunter CPUE during 1993–2002 which in fact had a limited relationship (r = 0.54, P = 0.11, Dining table 2). New dating between CPUE and you will abundance have been positive while in the 1993–2002 whilst 95% CI to own ? was indeed large and overlapped step 1.0 for both hunter and you may trapper CPUE (Fig step 3). 0 proving CPUE denied more rapidly on down abundances (Fig step 3). Huntsman CPUE encountered the most powerful reference to bobcat abundance (Roentgen 2 = 0.73, Desk 2). Good lines are projected matches from linear regression designs whenever you are dashed outlines is estimated suits of reduced significant axis regression of the log regarding CPUE/ACPUE resistant to the log regarding wealth. New based and you can separate details have been rescaled from the splitting of the maximum value.
