“…Much of the biodiversity of RN is still unknown, but in recent years vertebrate lists for some sites were published regarding fish (Nascimento et al 2014, Medeiros et al 2019, amphibians (Magalhães et al 2013, Caldas et al 2016, reptiles (Freire et al 2009, Sales et al 2009, Caldas et al 2016, Calixto & Morato 2017, Marques et al 2021, birds (Silva et al 2012, Pichorim et al 2014, Sagot-Martin et al 2020, terrestrial mammals (Marinho et al 2018, Cherem et al 2019), and bats (Vargas-Mena et al 2018. With respect to the herpetofauna, only two sites in RN have published lists based on long-term standardized sampling effort: one in the Caatinga for amphibians and reptiles (Freire et al 2009, Caldas et al 2016, and the other in a transitional area between Caatinga and Atlantic Forest only for amphibians (Magalhães et al 2013).…”

The herpetofauna of priority highland areas for conservation of the Caatinga in the state of Rio Grande do Norte, northeastern Brazil

The Brazilian Caatinga has already lost extensive areas of original vegetation, thus it becomes imperative to perform fauna inventories within this region to fill geographical sampling gaps. Herein, we present a taxonomic list of the herpetofauna of a mountain chain located in the central zone of Rio Grande do Norte (RN) state whose region includes two priority areas for conservation of the Caatinga: “CA087 – Serra de Santana” in the west, and “CA078 – Nascente do Potengi” in the east. The sampling was carried out using methods of visual searching, pitfall traps with drift fences, specimens rescued during vegetation suppression activities in wind energy projects, occasional encounters, and third-party records. We recorded 19 amphibian species and 53 reptile species (23 lizards, 24 snakes, five amphisbaenians and one chelonian). About half of the recorded species have distributions entirely or mostly in the Caatinga. The mountain range sampled in this study harbors virtually all species found in nearby lowlands of the “sertaneja” depression of RN state, plus some relevant species with relictual distributions in the Caatinga, highlighting the importance of these highland areas for conservation of the Caatinga herpetofauna.

The Neotropics are one of the richest regions in biodiversity globally. Still, much remains unknown about the mechanisms and processes responsible for the accumulation of species in this region. Among the many limitations on our current knowledge on the region's biodiversity, understanding of community composition and species distributions is limited and greatly biased in many Brazilian regions. We present information on species composition, habitat use, geographic distribution, taxonomic accounts, and conservation of snakes from Rio Grande do Norte state, Northeastern Brazil. We compiled, from primary and literature data, 851 snake records from seven families and 47 species, with fi ve new records for the state. Species are mainly terrestrial and semi-arboreal and associated with at least six vegetation types from Caatinga and Atlantic Forest domains. None of the species is listed in threatened categories of IUCN, while two species are listed in the Brazilian Threatened Fauna list. Our data covers 32.34% of the state's area, a consequence of locally limited inventories and lack of longterm studies on snakes' fauna. The richest areas within the state are near large cities, which lack protected areas for the species they harbor, and highlights the necessity of protective policies and conservation actions.

Clinical and post mortem examination of white worm lizards (Amphisbaena alba) in the State of Paraíba, Northeastern Brazil: morphological, pathological and radiographic findings of a secretive species

et al. 2021

Amphisbenians are limbless reptiles that belong to the order Squamata. Due to their fossorial and secrevie habits, little is known about their morphology, ecology and pathological conditions that may affect them. In this manuscript, we present a brief guide for identification of normal structures as well as traumatic injuries on radiography and necropsy of Amphisbaena alba. From April to September 2019, three cases of A. alba with suspected trauma were referred to the Veterinary Hospital of the Federal University of Paraíba (UFPB). In the clinical evaluation, traumatic injuries were observed, and support therapy was instituted, but they did not resist and died shortly after. Bone fractures and organ ruptures, in addition to specific structures of this species were identified on radiography. A systematic necropsy was performed of all amphisbaenians in order to evaluate external and internal structures, not only to identify lesions but also to investigate the morphological aspects of amphisbenids. Macroscopically, multiple organ fractures and ruptures observed in radiographs were confirmed, in addition to the presence of the cestodes Semenoviella amphisbaenae in the large intestine. Histologically, it was possible to identify normal characteristics and microscopic lesions in the tissues. This is the first study to incorporate morphological, clinical, and pathological aspects of A. alba. This manuscript brings essential information for wildlife veterinarians and pathologists who may have to treat or perform a necropsy on these unique reptiles.
