Fig. 7. UPGMA generated dendrogram illustrating the similarity relationships of species richness among the herpetofaunal components in the four physiographic regions of Veracruz (based on the data in Table 7; Sokal and Michener 1958). Similarity values were calculated using Duellman's (1990) Coefficient of Biogeographic Resemblance (CBR).

Fig. 3 in Evidence for cryptic diversity in the Neotropical water snake, Helicops angulatus (Linnaeus, 1758) (Dipsadidae, Hydropsini), with comments on its ecology, facultative reproductive mode, and conservation

Fig. 3. Best Maximum Likelihood tree based on the data set of concatenated 12S and 16S rDNA, and c-mos sequences. The red clade depicts the Helicops angulatus group. On the left and right sides of a slash (/) are values indicated at nodes for Maximum Likelihood bootstraps (> 75%) and Bayesian Posterior probability values (> 95%), respectively. Green clades represent the paraphyly of Helicops angulatus. The name Helicops pictiventris is currently a junior synonym of H. infrataeniatus, but it appears in the tree exactly as the pertinent sequences appear in the GenBank dataset.

Fig. 1 in Evidence for cryptic diversity in the Neotropical water snake, Helicops angulatus (Linnaeus, 1758) (Dipsadidae, Hydropsini), with comments on its ecology, facultative reproductive mode, and conservation

Fig. 1. The distribution of Helicops angulatus in the Neotropics. Locality data is from the VertNet and GBIF databases, as well as the literature. Diamonds (green oviparous, yellow viviparous): specimens reported in Appendix B of Braz et al. (2016); red stars represent localities where Helicops was sampled for DNA; small black markers: localities from Helicops angulatus map in Nogueira et al. (2019). As currently defined Helicops angulatus occurs in Freshwater Ecoregions: 301 North Andean Pacific Slopes, Rio Atrato; 302 Magdalena, Sinu; 304 South America Caribbean Drainages, Trinidad; 307 Orinoco Llanos; 308 Orinoco Guiana Shield; 311 Guianas; 313 Western Amazon Piedmont; 317 Ucayali, Urubamba Piedmont; 318 Mamore, Madre de Dios Piedmont; 319 Guapore, Itenez; 320 Tapajos, Juruena; 321 Madeira Brazilian Shield; 323 Amazonas Estuary and Coastal Drainages; 324 Tocantins, Araguaia; 325 Parnaiba; and 328 Northeastern Mata Atlantica.

Fig. 4 in The need for transboundary faunistics and conservation: first record of the Natterjack Toad (Epidalea calamita) in Czech Silesia, northeastern Czech Republic

Fig. 4. Maximum-likelihood phylogenetic tree showing the position of an individual from Krnov (in red) within the Clade A (sensu Rowe et al. 2006), indicating the non-exotic origin of the Krnov population. All other Czech samples (from Western Bohemia) are in bold. Codes correspond to GenBank numbers, and numbers at nodes are bootstrap support values

Fig. 2 in The need for transboundary faunistics and conservation: first record of the Natterjack Toad (Epidalea calamita) in Czech Silesia, northeastern Czech Republic

Fig. 2. Newly discovered locality of the Natterjack Toad (Epidalea calamita) in Krnov, Czech Silesia, Czech Republic. The distribution site is located within the Cvilín demolition waste dump, which used to be a sand quarry. (A) The site is now completely filled-up by demolition waste, an unfavorable condition for several species of amphibians present at the site. (B) Puddles are formed in small depressions after the movement of heavy-weight vehicles. However, the formation of such small puddles will probably stop in the near future as the waste dump is now closed. This is another unfavorable condition for this population, together with the surrounding grounds being overgrown by dense vegetation.

(A) Adult female (SVL 74 mm), (B) genetically tested subadult specimen, (C) adult male with an indistinct dorsal stripe, and (D) the smallest subadult (SVL 34 mm) that was found.

Fig. 1. Distribution range of the Natterjack Toad (Epidalea calamita) according to the IUCN Red List of Threatened Species (Beja et al. 2009), updated for the Czech Republic (inset). Red dots show all recent confirmed records (1997–2016; Šandera et al. 2017), demonstrating the very scattered distribution in the Czech Republic. The question mark denotes the region where the Natterjack Toad had occurred before 1990, but has since disappeared (AOPK ČR 2019; Jeřábková and Zavadil 2020). The green star shows the newly discovered population in Krnov, Czech Silesia.

Fig. 3 in Amphibian diversity and conservation along an elevational gradient on Mount Emei, southwestern China

Fig. 3. Local and overall elevational ranges for each amphibian species. For each species, the local elevational range is the maximum minus minimum elevation on Mount Emei (gray box or vertical line), and the overall elevational range size is the published elevational range covering the whole distribution range (the horizontal line).

Regression lines show total species richness (black) and threatened species richness (red) based on the polynomial regression models, with threatened status counts referring to the IUCN Red List (A) and the China Biodiversity Red List (B).
