However, previous studies revealed limited variability in cytoge- netic traits. The sex determination mode was revealed only in a handful of gerrhosaurid, skink, and xantusiid species, which demonstrated either ZZ/ZW or XX/XY sex chromosomes. In this study, we explored the karyotypes of six species of skinks, two species of cordylids, and one gerrhosaurid. We applied conventional and molecular cytogenetic methods, including C-banding, fluorescence in situ hybridization with probes specific for telomeric motifs and rDNA loci, and comparative genomic hybridization. The diploid chromosome numbers are rather conserved among these species, but the chromosome morphology, the presence of interstitial telomeric sequences, and the topology Citation: Kostmann, A.; of rDNA loci vary significantly.

Iran is a very active geographic area for any animals, and more especially for lizards, due to its wide range deserts and ecology. We have attempted to ascertain, as much as possible, the construction of the Latin binomials of all Iranian lizard species. We believe that a review of these names is instructive, not only in codifying many aspects of the biology of the lizards, but in presenting a historical overview of collectors and taxonomic work in Iran and Middle East region. We have listed all recorded lizards of Iran according to the order of the scientific names in the latter book; (Although two species have been left unnumbered in the book, we have included both in the numerical order). All lizard species and types have been grouped under their proper Families, and then they have been alphabetically ordered based on their scientific binominal nomenclature. We also examined numerous published works in addition to those included in the original papers presenting each binomial.

However, we lack an understanding of how these reversals happen mechanistically. A snake-like body form has evolved many times in vertebrates, and occasionally a quadrupedal form Received: 14 August 2020 has re-evolved, including in Brachymeles lizards. We use body form and loco- Accepted: 19 October 2020 motion data for species ranging from snake-like to quadrupedal to address how a quadrupedal form could re-evolve. We show that large, quadrupedal species are faster at burying and surface locomotion than snake-like species, indicating a lack of expected performance trade-off between these modes of locomotion.

  • Using Ancient and Recent DNA to Explore Relationships of Extinct and Endangered Leiolopisma Skinks (Reptilia: Scincidae) in the Mascarene Islands
    Molecular Phylogenetics and Evolution 39 (2006) 503–511 www.elsevier.com/locate/ympev Using ancient and recent DNA to explore relationships of extinct and endangered Leiolopisma skinks (Reptilia: Scincidae) in the Mascarene islands J.J. Austin 1, E.N. Arnold ¤ Department of Zoology, Natural History Museum, Cromwell Rd., London SW7 5BD, UK Received 29 August 2005; revised 15 December 2005; accepted 15 December 2005 Available online 10 February 2006 Abstract Phylogenetic analysis, using 1455 bp of recent mtDNA (cytochrome b 714 bp, 12S rRNA 376 bp) and nuclear (c-mos 365 bp) sequence from 42 species and 33 genera of Scincidae, conWrms Leiolopisma telfairii, now conWned to Round island oV Mauritius, is a member of the mainly Australasian Eugongylus group of the Lygosominae. Ancient mtDNA (cytochrome b 307 bp, 12S rRNA 376 bp) was also extracted from subfossils of two other Mascarene taxa that are now extinct: the giant L. mauritiana from Mauritius and Lei- olopisma sp., known only from fragmentary remains from Réunion. Sequence divergences of 4.2–5.7% show that all three forms were distinct and form a clade. There is restricted evidence that L. mauritiana and L. sp. from Réunion were sister species. Monophyly and relationships suggest Leiolopisma arose from a single transmarine invasion of the oceanic Mascarene islands from Australasia, 5600– 7000 km away. This origin is similar to that of Cryptoblepharus skinks and Nactus geckos in the archipelago but contrasts with Phel- suma day geckos, which appear to have arrived from Madagascar where Mascarene Cylindraspis tortoises may also have originated. DiversiWcation of the known species of Leiolopisma occurred from about 2.3–3.4 Mya, probably beginning on Mauritius with later invasion of Réunion.
