FIGURE 4 in Morphological and genetic diversification of pygmy and marbled newts, with the description of a new species from the wider Lisbon Peninsula (Triturus, Salamandridae)
FIGURE 4 Geographical clines observed for 'Triturus pygmaeus' in a longitudinal transect across central Portugal (see fig. 3), with T. rudolfi nov. sp. in the west and T. pygmaeus in the east. The horizontal axis is distance in km, measured from the nominal centre of the contact zone at Entroncamento railway station. The vertical axes are from top to bottom, left column – PCA2 for 54 SNP markers and the frequency of the eastern mtDNA haplotype, and in the right-hand column – the number of links and body size (lnSVl1) of adult males and females. Solid dots represent populations and the grey areas represent the 95% credibility intervals. Note that the colour bar is applied to fig. 3B. The formal cline descriptions are in supplementary table S3.

FIGURE 2 in Morphological and genetic diversification of Old-World marbled newts, with the description of a new and 'not-at-all-cryptic' subspecies from the Iberian Peninsula (Triturus, Salamandridae)
FIGURE 2 The distribution of two species of marbled newts over the western part of the Iberian Peninsula, as inferred from the morphological character Nlinks. Triturus marmoratus is shown in two shades of blue, T. pygmaeus in two shades of red and four localities with both species are shown in grey (see colour legend). The spatial extrapolation does not exceed ca. 50 km. Note that southern Iberian populations are all T. pygmaeus, irrespective of high (cluster C1), low (C2), or bimodal Nlink counts (Doñana National Park). Populations that were studied morphometrically are highlighted by a box. The type locality for T. pygmaeus lusitanicus ssp. nov. is Granja, Portugal and is marked by an asterisk.

FIGURE 4 in Morphological and genetic diversification of Old-World marbled newts, with the description of a new and 'not-at-all-cryptic' subspecies from the Iberian Peninsula (Triturus, Salamandridae)
FIGURE 4 Morphological and genetic variation in Triturus pygmaeus from in and around Doñana National Park (DNP). A – histograms of Nlink counts for four population groups with, from top to bottom: southwestern cluster of T. pygmaeus (localities 65, 436, 438 and 1004 in the south of Portugal, together marked C1 in fig. 2), populations in the northern section of DNP (ER, locality 1005 and BS, locality 1006), population in the southern section of DNP (locality 271) and the Betic cluster of T. pygmaeus (localities 270, 463, 465 and 1003 in the very south of Spain, together marked C2 in fig. 1). Exceptionally, the northern Doñana museum material contains 15 juvenile specimens (open bars) along with three adults (shaded bars). B – geographical cline in microsatellite genetic variation. The horizontal axis shows 'Distance from the Guadalquivir River' in km and the vertical axis presents Structure Q-scores. The solid round symbols represent populations and the grey area shows the 95% credibility interval. The Structure Q-scores were extracted from a published figure (Albert & García-Navas, 2022: Figure 4) and are unavoidably imprecise. The position of the 'Torre Carbonero', a cultural landmark at the Doñana beach, is shown by an arrow (TC). Three populations with morphological data available, that can be associated to the transect are El Rocío (arrow marked ER) and the biological station (BS) in northern Doñana and Zacallón C. de los Junqueros in southern Doñana (arrow marked 271). For details, see table 1 and supplementary table S1.
FIGURE 5 in Morphological and genetic diversification of pygmy and marbled newts, with the description of a new species from the wider Lisbon Peninsula (Triturus, Salamandridae)
FIGURE 5 Histogram for the number of links (Nlinks) observed in Iberian large-bodied newts, with low values for Triturus marmoratus (top panel), intermediate values for T. rudolfi sp. nov. (middle panel) and low to high values for T. pygmaeus (bottom panel). A distinction is made between T. p. pygmaeus from the Betic region (grey bars) and T. p. lusitanicus from the remainder of the species range (open bars) (see Arntzen, 2024). The optimal separation of T. rudolfi nov. sp. versus T. p. lusitanicus is achieved at Nlinks = 6.8, as shown by an interrupted line. To the right examples are shown of individuals with low and high link counts. Animals are facing left, with T. marmoratus from Gerês, northern Portugal at the top and T. p. lusitanicus from Sagres, southern Portugal at the bottom. Links are counted over the left and right side of the newts' bodies, in between the insertion of the fore- and hind leg. THE IMAGERY IS REPRODUCED FROM ARNTZEN (2018)
FIGURE 3 in Morphological and genetic diversification of Old-World marbled newts, with the description of a new and 'not-at-all-cryptic' subspecies from the Iberian Peninsula (Triturus, Salamandridae)
FIGURE 3 Nine marbled newts from three (sub)species each in dorsal and ventral view. Link counts for the left and right side of the body are given in parentheses. Top row – Triturus marmoratus from Jublains, France; left male (3, 2) and right female (1, 1). Middle row – T. pygmaeus lusitanicus ssp. nov. from Cardeña, Spain; from left to right female (2, 4), male (4, 3) and male (4, 5). Bottom row – T. p. pygmaeus from Salinas, Spain; from left to right male (2, 1), male (1, 2) male (2,0) and female (3, 1). Note that the colour pattern in T. marmoratus and T. p. pygmaeus is horizontally banded whereas in T. p. lusitanicus ssp. nov. it is reticulated. PHOTOGRAPHY L. A. VAN DER LAAN
