FIG. 6 in Courtship and Mating Behavior of the Rare, Rock-Crevice Dwelling Salamander Plethodon petraeus with a Review for Eastern North American Woodland Salamanders (Amphibia: Plethodontidae)

FIG. 6. Total duration (min) of some behaviors and periods during complete courtships in the salamander Plethodon petraeuS. Data are from ten individually unique pairs that engaged in complete courtship with tail-straddling walk (TSW) and spermatophore deposition. For Pair 3 courtship, there were two spermatophore depositions, but this figure only includes data from the first spermatophore deposition. A ¼ Courtship duration from initial close encounter between salamanders until the retrieval or attempted retrieval of the first spermatophore cap. B ¼ Total of all periods when salamanders were more than about 2.5 cm apart after their initial encounter. D ¼ Total duration for female-first TSW, which includes both discontinuous and continuous forms of the duet behavior. Pearson Product Moment correlation coefficients: r ¼ 0.882, P, 0.001 for B and D; r ¼ 0.952, P, 0.0001 for B and F; r ¼ 0.964, P, 0.00001 for C and E; r ¼ 0.961, P, 0.00001 for D and F. See Table 2 for additional data on the duration of other behaviors and periods.
