1. Habitat structure and their influence in lizard’s presence
Abstract Many species are declining due to environmental and physical changes in their habitats. Such disturbs alter the availability of micro-habitats and influences the presence of lizards, being even worse for threatened and endemic species. Glaucomastix littoralis is a teiid species restricted to four restingas areas of Brazil. The understanding about th

2. Impact of immunological state on eco-physiological variables in one of the southernmost lizards in the world
Abstract: The immune state is an essential component of survival as it directly influences physiological performance and health status. Variation in the leukocyte profile, a significantly increase in body temperature, and a detriment of the eco-physiological performance are among the possible consequences of an unhealthy state. In this study we analyse and

3. Rediscovering a forgotten scientific collection in the Rio Grande do Norte State, Brazil: The herpetological collection of the zoologist José Santiago Lima-Verde
Resumo: O zoólogo Dr. José Santiago Lima-Verde (1945-2019) fez uma série de importantes contribuições para o campo da biologia animal no nordeste do Brasil, em particular através de sua pesquisa com serpentes. Enquanto professor da Escola Superior de Agricultura de Mossoró, atualmente Universidade Federal Rural do Semi-Árido, o Prof. Lima-Verde estab

4. Reproductive and feeding biology of the common lancehead Bothrops atrox (Serpentes, Viperidae) from central and southwestern Brazilian Amazonia
RESUMO A jararaca Bothrops atrox é uma serpente de ampla distribuição e de importância médica na Amazônia. Visto que a biologia reprodutiva e alimentar de serpentes varia geograficamente, nosso objetivo foi o de caracterizar a história natural de indivíduos provenientes das porções central e sudoeste do bioma no Brasil. Analisamos espécimes preser

5. Lizard assemblages on sandy coastal plains in southeastern Brazil: An analysis of occurrence and composition, and the role of habitat structure
Abstract Data on the structure of lizard communities in the different biomes and ecosystems of Brazil are still limited. In this study, we related the species richness, abundance and the spatial occurrence of lizards to the structure of the vegetation found on the coast of the state of Espírito Santo, southeastern Brazil, to determine whether habitat influe

6. Morphological and histological characterization of sexual segment of the kidney in Notomabuya frenata (Cope, 1862) and Aspronema dorsivittatum (Cope, 1862) (Squamata, Mabuyidae)
Abstract The kidneys in two viviparous species of Neotropical lizards, Notomabuya frenata and Aspronema dorsivittatum (Mabuyidae), were investigated by light and scanning electron microscopy in order to determine the presence of the sexual segment of the kidney (SSK) and to study its morphology. The individuals used in this study belong to the Herpetological

7. New data on the Late Cretaceous lizard Dicothodon bajaensis (Squamata, Borioteiioidea) from Baja California, Mexico reveals an unusual tooth replacement pattern in squamates
Abstract Borioteiioids comprise an extinct family of squamates that inhabited the Northern Hemisphere during the Cretaceous and were characterized by varying patterns of tooth replacement and dental morphology. Understanding the evolution of these tooth replacement patterns has, however, been largely hampered by an extremely fragmentary fossil record. Here w

8. The Herpetofauna from Ilha Grande (Angra dos Reis, Rio de Janeiro, Brazil): updating species composition, richness, distribution and endemisms
Abstract Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork an

9. Body orientation for thermoregulation and daily activity cycle of Mabuya macrorhyncha (Squamata: Scincidae)
ABSTRACT We investigated the daily activity and thermoregulatory body orientation of Mabuya macrorhyncha (Hoge, 1947), a lizard species that occurs in the Brazilian Atlantic Forest. We conducted this investigation in a sandy coastal dune remnant (“restinga” ecosystem) in Grussaí, state of Rio de Janeiro, Brazil, during the summer. The daily activity cyc

10. Estudios arqueofaunísticos en un contexto estratigráfico de las llanuras interiores de Entre Ríos: el sitio Laguna del Negro 1 (departamento Gualeguay, Argentina)
Abstract The virtual absence of zooarchaeological data from the extensive inland plains of Entre Ríos, northeastern Argentina, can be explained by the scarcity of archaeological investigations and the lack of stratigraphic contexts available for study. Recently, the detection and excavation of Laguna del Negro 1, a late Holocene site with evidence of multip

11. Approaches to capturing the Black and White Tegu Salvator merianae (Squamata: Teiidae)
ABSTRACT The use of traps is extremely important in several types of ecological studies, and may assist in the capture of individuals in areas that are difficult to access. In the present study, we compared the effectiveness of wooden (Schramm) versus "Tomahawk" traps to capture Salvator merianae (Duméril & Bibron, 1839) lizards. The study was conducted in

12. Simplified three-dimensional model provides anatomical insights in lizards' caudal autotomy as printed illustration
A autotomia caudal é um mecanismo anti-predação complexo e amplamente utilizado por lagartos, que envolve diversas adaptações anatômicas. Por seu tamanho diminuto e estruturas intrincadas, é difícil explicar claramente a anatomia vertebral para estudantes e pesquisadores de outras áreas. Modelos tridimensionais são ferramentas prodigiosas no esclar
