New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

Morphophysiological dynamics of the proximal post‐testicular ducts in Crotalus durissus Linnaeus, 1758 (Squamata: Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The organization and function of reptilian excurrent ducts remain poorly characterized, particularly in Neotropical snakes. We provide the first integrative morphological, histochemical, immunohistochemical, and ultrastructural analysis of the proximal post‐testicular ducts of Crotalus durissus across reproductive stages.

First record of mitochondrial genome of Scincella reevesii (Squamata: Scincidae) and phylogenetic analysis

open access: yesMitochondrial DNA. Part B. Resources, 2021
We sequenced and annotated the nearly complete mitochondrial genome (mitogenome) of Scincella reevesii (Squamata: Scincidae). This mitogenome was 14,106 bp in size and encoded 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes ...

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

open access: yesThe Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Acari of lizards from Atlantic Forest in northeastern Brazil [PDF]

open access: yesNeotropical Biology and Conservation, 2019
Although mites are often associated with reptiles, there is little information available about parasites of lizards in Brazil. The aim of this study was to identify the ectoparasites of the lizards Kentropyx calcarata (Squamata: Teiidae ...

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Landscape drivers of scaled quail occurrence across a broad spatiotemporal scale: implications for habitat management

open access: yesThe Journal of Wildlife Management, EarlyView.
Combining large‐scale avian surveys with remote sensing products revealed landscape variables that likely limit scaled quail occurrence at the ecoregion scale in Texas. Promoting management practices that address ecoregion‐specific limiting factors may be key to averting further declines.

Understanding thermal conditions provides context for the influence of habitat characteristics on gamebird winter ecology

open access: yesWildlife Biology, EarlyView.
The fundamental niche of an organism is regulated partially by its ability to cope with a range of thermal environments, which can be directly influenced by management across spatial scales and seasons. However, despite winter weather being a major source of mortality for many species in northern latitudes, the impact of thermal conditions on wintering

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

open access: yesIntegrative Zoology, EarlyView.
We produced HiFi long reads and assembled a high‐quality genome for the Guinan toad‐headed lizard—Phrynocephalus guinanensis—and present a comprehensive conservation genomics assessment. Our findings clearly show population structure, a reduced genetic diversity pattern, and a strong bottleneck in demographic history, reaffirming the endangered status ...
