    The New Mexico whiptail (Aspidoscelis neomexicanus) is a female-only species of lizard found in the southwestern United States in New Mexico and Arizona, and in northern Mexico in is the official state reptile of New Mexico. It is one of many lizard species known to be duals of the species can be created either through the hybridization of the little Family: Teiidae.   Evolution and ecology of lizard body sizes Evolution and ecology of lizard body sizes Meiri, Shai INTRODUCTION Body size is known to greatly influence many aspects of the morphology, physiology and ecology of organisms. Furthermore, size often is linked to the likelihood of speciation and extinction and to the rate of evolution, as well as to current levels of Author: Meiri, Shai. Reference List. This reference list is a compilation of all the reference lists posted on this Web Site so far. These references can also be found within the appropriate chapter, . Parthenogenesis, unisexuality and triploidy are interesting but poorly studied phenomena occurring in some reptile species. The mourning gecko (Lepidodactylus lugubris) represents a complex of diploid and triploid parthenogenetic mostly all-female populations (males occur quite rarely) widely distributed in coastal areas of the Indian and Pacific Oceans. Here, we study karyotypes of a male and Cited by:

We still lack any data for the Cordylidae (girdled lizards; 68 sp.), Gerrhosauridae (plated lizards; 37 sp.) or–the focus of the present study–Xantusiidae (night lizards; 35 sp.), and this paucity of data limits our ability to study macro-evolutionary patterns of sex chromosome evolution both across this clade, and in squamates as a whole.

Xantusiidae (night lizards) is a clade of small-bodied, cryptic lizards endemic to the New World. The clade is characterized by several features that would benefit from interpretation in a phylogenetic context, including: (1) monophyletic status of extant taxa Cricosaura, Lepidophyma, and Xantusia; (2) a species endemic to Cuba (Cricosaura typica) of disputed age; (3) origins of the Cited by: Testing species boundaries in an ancient species complex with deep phylogeographic history: genus Xantusia (Squamata: Xantusiidae).

Femoral pores are a part of a holocrine secretory gland found on the inside of the thighs of certain lizards and amphisbaenians which releases pheromones to attract mates or mark territory. In certain species only the male has these pores and in other species, both sexes have them, with the male's being larger.

Despite the absence of microchromosomes in the mammalian genome, they form a substantial portion of the karyotype in most amniotes (Burt ).Microchromosomes are structurally similar to macrochromosomes (they have telomeres and centromeres, for example) and behave similarly during mitosis and meiosis (Burt ), although they Cited by:   A paper I came across in Nature from last year explains a potential reason why – if you are a parthenogenetic species (reproduction without males), you lack the ability to obtain genetic variation from your mate.

mitochondrial DNA sequence analysis of relationships among lizards in the family Xantusiidae (Hedges et al, ). The monotypic genus Cricosaura, isolated in a remote area of Cuba, is the only xantusiid lizard in the West Indies. All other xantusiids occur in Central America and southwestern North America.

Morphological studies. Phylogenetic relationships of the whiptail lizards of the genus Cnemidophorus are inferred based on a combined analysis of mitochondrial DNA, morphology, and allozymes.

Within the Teiini, Teius and Dicrodon are the most basal lineages, and these two taxa form a graded series leading to a cnemidophorine clade containing Ameiva, Cnemidophorus.
