Lizard populations found in insular environments may show ecological and morphological characteristics that differ from those living in continents, as a result of different ecological and evolutionary processes. In this study, we analyzed sexual dimorphism, reproduction, and diet in a population of the whiptail lizard, Aspidoscelis costata, from Isla Isabel, Nayarit, Mexico, sampled in 1977 and 1981. Males and females from Isla Isabel showed no sexual dimorphism in many morphological structures, such as snout-vent length (SVL), but they did in femur length (FL) and tibia length (TL). Both sexes displayed synchronous reproductive cycles. However, males had smaller SVL (47.0 mm) in average than females (59.0 mm) at sexual maturity. The average clutch size was 2.4 eggs, but there was no correlation between egg number and female’s SVL. The diet of A. costata consisted of insects, arachnids, crustaceans, and plant material. Insects were the most consumed prey item, being mostly represented by orthopterans, coleopterans, and hymenopterans. Diet breadth of males was higher (Levin´s formula, B = 0.596) than in females (B = 0.358), and diet overlap between sexes was relatively high (Pianka’s index, Ojk = 0.822), with an overlap ranging from 66.2 to 100%. The population of A. costata from Isla Isabel shows different morphological and ecological characteristics from their continental counterparts, but future studies on whiptail species with island and mainland populations are required to determine the ecological and evolutionary patterns.

For example, Andrews (1979) found vertebrates inhabiting islands (Lomolino et al. high sexual dimorphism in lizard populations of 2006). Sexual dimorphism and diet preference are the genus Anolis, with sexual dimorphism biased central components for understanding life-history to males and mainly caused by competition for evolution of lizard species inhabiting islands (An- food resources and territory.

  • Xenosaurus Tzacualtipantecus. the Zacualtipán Knob-Scaled Lizard Is Endemic to the Sierra Madre Oriental of Eastern Mexico
    Xenosaurus tzacualtipantecus. The Zacualtipán knob-scaled lizard is endemic to the Sierra Madre Oriental of eastern Mexico. This medium-large lizard (female holotype measures 188 mm in total length) is known only from the vicinity of the type locality in eastern Hidalgo, at an elevation of 1,900 m in pine-oak forest, and a nearby locality at 2,000 m in northern Veracruz (Woolrich- Piña and Smith 2012). Xenosaurus tzacualtipantecus is thought to belong to the northern clade of the genus, which also contains X. newmanorum and X. platyceps (Bhullar 2011). As with its congeners, X. tzacualtipantecus is an inhabitant of crevices in limestone rocks. This species consumes beetles and lepidopteran larvae and gives birth to living young. The habitat of this lizard in the vicinity of the type locality is being deforested, and people in nearby towns have created an open garbage dump in this area. We determined its EVS as 17, in the middle of the high vulnerability category (see text for explanation), and its status by the IUCN and SEMAR- NAT presently are undetermined. This newly described endemic species is one of nine known species in the monogeneric family Xenosauridae, which is endemic to northern Mesoamerica (Mexico from Tamaulipas to Chiapas and into the montane portions of Alta Verapaz, Guatemala). All but one of these nine species is endemic to Mexico.

Morphological comparison of the Honduran populations to Cnemidophorus populations from Panama led to the conclusion that the Pan- amanian population represents an undescribed species named herein. In light of these new results, and considering past morphological studies of several South American populations of the C. lemniscatus group, we suggest that three other nominal forms of the group are best treated as valid species: C. espeuti (described as a full species, but subsequently treat- ed as a synonym of C. lemniscatus or a subspecies of C.

In the late Pleistocene or early Holocene, it lizards in the genus Cnemidophorus are generally called “Whiptail Lizards” became connected to the mainland by a narrow strip of dunes. During the or “Racerunners,” whereas those in the genus Ameiva are called “Jungle ice ages, when sea levels were much lower, it was part of the South American Runners.” The genera differ in the number of rows of ventral scales and in mainland. Aruba might at one time have been connected to the mainland; the structure of the bones in the tongue.

  • Region 2 Other Emphasis Species List Triploid Colorado Checkered
    Region 2 Other Emphasis Species List Triploid Colorado Checkered Whiptail / Aspidoscelis neotesselatus (syn Cnemidophorus neotesselatus) Recommendation Rationale: Not R2 SS, But Should Be Considered For Other Emphasis Species Lists This species is a Colorado endemic, found only in some foothills areas of the upper Arkansas River Drainage and the Purgatoire River drainage. It also is a very unique species, as it is parthenogenetic and thought to have originated relatively recently from hybridization between an individual of C. tigris and a C. gularis, yielding a reproducing population and new species. The hybrids had one set of chromosomes from each parent. A member of that population is then thought to have hybridized with a six-lined racerunner (C. sexlineatus), which led to the current population, having three complete sets of chromosomes. Several subpopulations have been eliminated or substantially reduced due to urbanization in the Pueblo area and land use conversion. Nonetheless, Hammerson (1999) considers the species to be somewhat adaptable and tolerant. It remains relatively common in foothill pinyon-juniper/grassland communities of western Pueblo and Fremont counties, and on or near portions of the Comanche NG in the Purgatoire River drainage. Because the species remains locally common, habitat in portions of its range remain reasonably secure, and the species exhibits some adaptability, it does not appear to merit sensitive species status at this time. However, since the species is a localized endemic, has very restricted distribution, and is very unique biologically, we believe the status of the species should be monitored and that the continued welfare of the species on NFS administered lands should be ensured.
