FIG. 4 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. 4. Time elapsed before the first occurrence of some courtship behaviors in the salamander Plethodon petraeuS. Data are from 20 individually unique pairs that engaged in ten incomplete courtships, which did not proceed to a tail-straddling walk (TSW), and ten complete courtships with TSW and spermatophore deposition. See text for description of behaviors. Number within brackets is the number of courtships with the behavior. Box plots show minimum, maximum, median (solid horizontal line), mean (dotted horizontal line), and percentiles (10th, 25th, 75th, and 90th).
