Fig. 11 in Hybridization Between the Endangered Unisexual Gray-Checkered Whiptail Lizard (Aspidoscelis dixoni) and the Bisexual Western Whiptail Lizard (Aspidoscelis tigris) in Southwestern New Mexico

Fig. 11. Topographic map of Antelope Pass, Hidalgo County New Mexico showing the 23 trap sites listed in table 6. Each site can be identified by its coordinates and symbol (table 6). Triangles indicate sites where A. dixoni C was found, but not A. t. punctilinealis; squares indicate sites where A. t. punctilinealis was found, but not A. dixoni C; and dots indicate sites where both species were found. This was mapped with TOPO! (2003, National Geographic; www.nationalgeographic.com/topo).

Fig. 7 in Hybridization Between the Endangered Unisexual Gray-Checkered Whiptail Lizard (Aspidoscelis dixoni) and the Bisexual Western Whiptail Lizard (Aspidoscelis tigris) in Southwestern New Mexico

Fig. 7. Pattern of morphological variation expressed by the distribution of scores on the first two principal components extracted from a correlation matrix of seven meristic characters of 30 specimens of Aspidoscelis from Antelope Pass, Hidalgo County, New Mexico. The specimens include representatives of two species (A. dixoni C and A. t. punctilinealis) and hybrids between them. Note that the three hybrids cluster most closely to their maternal parent.

Fig. 5 in Hybridization Between the Endangered Unisexual Gray-Checkered Whiptail Lizard (Aspidoscelis dixoni) and the Bisexual Western Whiptail Lizard (Aspidoscelis tigris) in Southwestern New Mexico

Fig. 5. Karyotypes of two whiptail lizards (Aspidoscelis) from Antelope Pass, Peloncillo Mountains, Hidalgo County, New Mexico. A, Diploid unisexual A. dixoni C (AMNH R-148360, fig. 3), with 2n 5 46 chromosomes. This taxon is a clone with its ultimate ancestor having been an F1 hybrid between A. tigris marmorata (haploid complement of chromosomes in the upper two rows) X A. gularis septemvittata (haploid complement in the lower two rows of A). Note that the X chromosome that was ultimately inherited from marmorata (third largest, upper row) was apparently fissioned at the centromere (arrow) forming two additional set II-sized macrochromosomes (here arranged to suggest the ancestral unfissioned state in marmorata). Note also that the missing microchromosome of A. dixoni C is illustrated as missing from the marmorata genome (o at the right end of the second row), although we do not know from which genome it was actually lost. B, Triploid hybrid female of A. dixoni C X A. t. punctilinealis (AMNH R-148141, fig. 3), with 3n 5 69 chromosomes arranged in six rows. Rows 2 and 4 represent the haploid complement most recently inherited from A. t. punctilinealis, including its intact X chromosome (third largest). Rows 1, 3, 5, and 6 represent the two haploid complements inherited from A. dixoni C, including the fissioned X (arrow) chromosome and missing microchromosome (o), as in A, above. Bar represents 10 Mm.

Fig. 6 in Hybridization Between the Endangered Unisexual Gray-Checkered Whiptail Lizard (Aspidoscelis dixoni) and the Bisexual Western Whiptail Lizard (Aspidoscelis tigris) in Southwestern New Mexico

Fig. 6. Electrophoretic phenotypes representing products of four gene loci of Aspidoscelis. A, IDDH, a tetrameric enzyme, from liver homogenates of seven lizards. Note that the b-allele from PUN is very faint but present in the hybrid. B, PEPA, a dimeric enzyme, from muscle homogenates of seven lizards. Note that New Mexican dixoni differ from Texan dixoni and that the hybrid is triallelic. C, sMDH, a dimeric enzyme, from muscle homogenates of seven lizards. Note that New Mexican dixoni differ from Texan dixoni and the hybrid shows two doses of the a-allele. D, MPI, a monomeric enzyme, from muscle homogenates of eight lizards. Note that New Mexican dixoni differ from Texan dixoni. Letters below gels identify allozymes based on alleles present (table 2). Lanes for individual lizards are labeled beside the gel (with genotype) as follows: DIXA, A. dixoni A; DIXB, A. dixoni B; DIXC, A. dixoni C; DIXC X PUN, hybrid of A. dixoni C X A. t. punctilinealis; MAR, A. t. marmorata; SCA, A. g. scalaris, which at these loci are often the same as A. g. septemvittata; TESC, A. tesselata C-E; TESD, A. tesselata D; TESE-C, A. tesselata E-C; PUN, A. t. punctilinealis. Anode is to the right, and arrow in A indicates position of sample application.

Fig. 1. The global distributional range of Aspidoscelis dixoni. This species occurs in two areas that are separated by approximately 500 km from which no specimens are known. The two areas are Antelope Pass, Peloncillo Mountains, Hidalgo County, New Mexico, and Chinati Mountains, Presidio County, Texas. Initialisms are as follows: AZ, Arizona; MX, Mexico; NM, New Mexico; and TX, Texas. Modified from Topo USA 2.0, DeLorme, Yarmouth, Maine (1999).

In A. dixoni C (no photograph of ventral view) there is no black on the abdomen or throat, although there may be a few small black dots on the chest.
