The conservation status of the world's reptiles

A Phylogenetic, Biogeographic, and Taxonomic study of all Extant Species of Anolis (Squamata; Iguanidae)
TLDR
A phylogenetic analysis of all 379 extant species of Anolis, with new phylogenetic data for 139 species including new DNA data for 101 species is presented, using the resulting estimates as a basis for defining anole clade names under the principles of phylogenetic nomenclature and to examine the biogeographic history of anoles.

Phylogeny of the lizard subfamily Lygosominae (Reptilia: Scincidae), with special reference to the origin of the new world taxa.
Phylogenetic relationships of the three lygosomine skink genera occurring both in the Old World and the New World (Mabuya, Scincella and Sphenomorphus) were inferred from mitochondrial DNA sequence…

Mitochondrial DNA phylogeography of the Mesoamerican spiny‐tailed lizards (Ctenosaura quinquecarinata complex): historical biogeography, species status and conservation
TLDR
Using mitochondrial DNA sequence data from fresh samples and formalin‐fixed museum specimens to investigate the genetic and biogeographic diversity of the threatened Mesoamerican spiny‐tailed lizards of the Ctenosaura quinquecarinata complex, three monophyletic, allopatric lineages are established using mtDNA phylogenetic and nested clade analyses.

COMMENTS ON EUSPONDYLUS AND PROCTOPORUS (SQUAMATA: GYMNOPHTHALMIDAE) FROM PERU, WITH THE DESCRIPTION OF THREE NEW SPECIES AND A KEY TO THE PERUVIAN SPECIES
TLDR
The new species are distinguished from all species presently assigned to Proctoporus and Euspondylus by unique characteristics of pholidosis, morphometrics, and color pattern.

Characters of external morphology used in Anolis taxonomy-definition of terms, advice on usage, and illustrated examples.
TLDR
With the aim of establishing a reference for taxonomists, characters of external morphology that have been used widely in descriptions of Anolis (sensu lato) species are described and discussed.

Tadpole diversity of Bolivia's lowland anuran communities: molecular identification, morphological characterisation, and ecological assignment.
TLDR
This study presents morphological tadpole characterisations of 41 lowland species illustrated by detailed imagery (mainly of live specimens) and provides information on tadpole habitats, which--combined with morphological data--reveal ecomorphological guilds that further illustrate Bolivia's lowlands tadpole diversity.

The Amphibians & Reptiles of the Bay Islands And Cayos Cochinos, Honduras
A Revision of the Fish Scale Geckos, Genus Geckolepis Grandidier (Squamata, Gekkonidae) from Madagascar and the Comoros
TLDR
The results of the morphological study, which examined 178 specimens representing most of the intact museum specimens that are currently available, find a total of three valid species within the genus Geckolepis: G. typica, G. maculata, and MNHN 1994.
