FIGURE 1. Geographical representation of the distribution of Venezuelan salamanders, and of the collecting sites nearby Mérida city sampled in this and previous works. A Salamanders of the genus Bolitoglossa reported for Venezuela include B. borburata (1), B. guaramacalensis (2), B. orestes (3), B. spongai (4) and B. altamazonica (5), for which the corresponding type localities are drawn as white circles. B Location of the geographical region in Cordillera de Mérida chosen for sampling efforts at cloud forests nearby Mérida city; the box in white is drawn at bigger scale in C. C Sampling locations are drawn as inverted black triangles at different places of Sierra La Culata and Sierra Nevada de Mérida; the map shows the main geographical features in, and between, both local Andean ranges.

FIG. 7 in The Evolution of Courtship Behavior in Plethodontid Salamanders, Contrasting Patterns of Stasis and Diversification
FIG. 7.—The evolutionary origin and loss of key courtship traits in Ensatina, Aneides, and Plethodon. Character origins are shown with solid rectangles; loss is shown with open rectangles: TSW ¼ tail-straddling walk module, c-TSW ¼ circular tail-straddling walk, tbf ¼ turning back towards the female during TSW, tpd ¼ transdermal pheromone delivery (tpd1 and tpd2), opd ¼ olfactory pheromone delivery, fd ¼ foot dance, ps ¼ pulling and snapping, tw ¼ tail wagging, and mgr ¼ mouth grasping. The time of origin or loss for each trait is bounded by the times at the ends of the branch on which it resides. Timecalibrated phylogeny based on Kozak et al. (2009); time scale shown in millions of years.
FIG. 2 in The Evolution of Courtship Behavior in Plethodontid Salamanders, Contrasting Patterns of Stasis and Diversification
FIG. 2.—Inventory of behavior patterns used in descriptions of plethodontid and rhyacotritonid courtship, showing their assignments to modules and submodules. Module abbreviations: AP ¼ approach, HC ¼ head contact, TSW ¼ tail-straddling walk, SD ¼ spermatophore deposition, POS ¼ positioning. Submodule abbreviations: pur ¼ male pursuit of female, pd ¼ preliminary display, con ¼ contact, tpd1 ¼ transdermal pheromone delivery Type 1, walk ¼ progress aspect of TSW, tpd2 ¼ transdermal pheromone delivery Type 2, oph ¼ olfactory pheromone delivery. Behaviors shown in the same colors occur in the same temporal context. Behaviors shown in shades of the same color occur in the sequence: lighter shade earlier, darker shade later. References for behavioral descriptions: 1 ¼ this study; 2 ¼ Arnold (1972); 3 ¼ Verrell and Mabry (2003); 4 ¼ Kiemnec-Tyburczy and Sapp (2017); 5 ¼ Doten et al. (in press); 6 ¼ Picard (2005); 7 ¼ Organ (1960b); 8 ¼ Organ (1960a); 9 ¼ Organ (1961); 10 ¼ Verrell (1999); 11 ¼ Sapp and Kiemnec-Tyburczy (2011).
FIG. 4 in A Long-term Demographic Study of a Spotted Salamander (Ambŋstoma maculatum) Population in Central Ohio
FIG. 4.—Mean values (±1 SE) for mass of juvenile Ambŋstoma maculatum sampled from Taylor–Ochs Pond, Ohio. Sample sizes are 99 (2005), 73 (2006), 301 (2008), 19 (2010), and 32 (2011). Different letters signify statistical differences between values (P <0.05).
FIGURE 3 in A systematic revision of the Shovel-nosed Salamander (Plethodontidae: Desmognathus marmoratus), with re-description of the related D. aureatus and D. intermedius
FIGURE 3. An adult (~58mm SVL) specimen (USNM 596935/RAP2886) of Desmognathus marmoratus from Glade Creek (WV: Raleigh), isolated on white (a) and black (b) backgrounds in dorsolateral view. Note the smaller, stockier body and indistinct silvery-gold lichenous dorsal markings. This isolated population in the New River Gorge occurs ~120 airline km away from the nearest known sites in the Upper Tennessee drainage of Virginia (Fig. 1).

FIGURE 4. Linear discriminant analysis of 142 samples from the four species of Shovel-nosed Salamanders (a), based on 17 measurements taken from vouchered specimens (Appendix S1), with a boxplot for Axilla-Groin length (AG; b) and Snout-Gular Length (SG; c) scaled by size for each species, selected from the heaviest loadings of the 16 variables indicated on a relative scale as grey rays in (a). Non-overlapping notches indicate significant median differences.
