Figure 1. (a) Distribution of both species displaying reproductive polymorphism, Salamandra salamandra (in blue) and Salamandra algira (in green). In red, the area of occurrence of pueriparity within each species. Values next to each pueriparous nuclei denote the frequency of multiple paternity. (b) Detail of the western-most distribution area of S. algira where the pueriparous lineage occurs (in red). The box shows the number of fathers and the proportion of the offspring sired by each male for all four studied females. Numbers in brackets are clutch size in each female.

Figure 3. Effect of total aquatic vegetation (standardized) on detection of Western Tiger Salamanders (Ambystoma mavortium; ±95% confidence interval), based on all sampling methods. Total aquatic vegetation is the sum of percent cover of emergent vegetation, submerged vegetation, and algae.

Figure 1. Waterbodies sampled for Western Tiger Salamanders (Ambystoma mavortium) and sub-species in northern Sonora, Mexico, during 2015-2018. Yellow circles indicate locations where salamanders were estimated to be present, white circles indicate where salamanders were not detected, and turquoise triangles indicate sites where Jones et al. (1988) sampled in 1983 and did not detect A. mavortium. The red star indicates the approximate location of Cananea, Sonora.

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).
FIG. 5 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. 5. Frequency of some female behaviors during the preliminary (pre-TSW) phase of courtship 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. Box plots show minimum, maximum, median (solid horizontal line), mean (dotted horizontal line), and percentiles (10th, 25th, 75th, and 90th). **, *Probability values from Mann-Whitney rank sum tests demonstrate a significant difference between complete and incomplete courtships for the frequency of both turn back and chin over.

FIG. 2. Duration of some behaviors and periods during the preliminary (pre-TSW) phase of courtship 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. Close ¼ salamanders 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, tail undulation, nudging, and snout under). MG Sliding ¼ mental-gland sliding on the skin of the female. ffTSWd ¼ discontinuous, female-first TSW. ffTSWc ¼ continuous, female-first TSW. Position for TSW ¼ attempted male solicitation of TSW. Box plots show minimum, maximum, median (solid horizontal line), mean (dotted horizontal line), and percentiles (10th, 25th, 75th, and 90th). *, **Probability values from Mann-Whitney rank sum tests demonstrate a significant difference between complete and incomplete courtships for the duration of both close and ffTSWd.
