Relationship between spraint densities and otter numbers.
Linear regressions between number of genotyped otter samples per ha (S) and (A) number of genotypes per ha (G) (R2 = 0.62, df = 4, p = 0.063) and (B) number of estimated individuals (E) (R2 = 0.24, df = 4, p = 0.33), respectively. Equations for both regressions are offered.
