  1. The correlation coefficients show the relationship between log(LTC + 1) and log(CB-LTC + 1). The regression slopes are from regressing relative sampling efficiencies (log(CB-LTC + 1)−log(LTC + 1)) on average abundance ([log(CB-LTC + 1) + log(LTC + 1)]/2)
  2. n sample size, r Pearson’s correlation coefficient, b regression slope, CI confidence interval, t t-test value, p probability value
