Table 2 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)

Table 2. Duration (min) of behaviors and phases during courtship and mating 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. (A) Apart ¼ periods when salamanders were more than about 2.5 cm apart after their initial encounter. (B) Close ¼ periods when salamanders were within about 2.5 cm of each other but not in sustained contact via the mental gland (e.g., includes periods with male foot dance/shuffle, undulate tail, mental-gland tap/swipe, nudge, and snout under). (C) Sliding ¼ mental-gland sliding. (D) ffTSWd ¼ discontinuous, female-first TSW. (E) ffTSWc ¼ continuous, female-first TSW. (F) upTSW ¼ unsuccessful position for TSW. (G) spTSW ¼ successful position for TSW. (H) TSW ¼ tail-straddling walk. (I) SD ¼ spermatophore deposition. (J) LOS ¼ lead female over spermatophore. (K) POC ¼ position on sperm cap. *Successful retrieval of sperm cap. Total B to G ¼ duration of pre-TSW phase of courtship. Total B to K ¼ total duration of pre-TSW phase, TSW, and sperm transfer. Total A to K ¼ total duration of courtship from the initial encounter between salamanders until the final attempted retrieval of sperm cap. Pearson Product Moment correlation coefficients (which do not include durations for behaviors from the second courtship sequence for pair 3): 1 r ¼ 0.952, P, 0.0001 for Apart and TSW; 2 r ¼ 0.770, P, 0.01 for Sliding and ffTSWd; 3 r ¼ 0.964, P, 0.00001 for Sliding and upTSW; 4 r ¼ 0.765, P, 0.01 for ffTSWd and upTSW.
