Frugivory in Ameiva ameiva (Squamata: Teiidae) in a white-sand ecosystem of Central Amazonia, Brazil
type: item
description: Observations and natural history records of reptiles are crucial for understanding their ecology, particularly in the context of rapid habitat loss in the Amazon. Although the teiid lizard Ameiva ameiva is an active forager whose diet is well documented as being primarily arthropod‑based, records indicate dietary plasticity that includes the consumption of plant material. Here, we document the first observation of A. ameiva consuming the fruit umari (Poraqueiba sericea) in a white‑sand ecosystem (WSE) of the Central Amazon, Brazil. The lizard was observed actively feeding on the pulp of fallen fruits, suggesting that umari, which is rich in lipids and carotenoids, may serve as an alternative or supplemental energy source. This observation expands the known dietary breadth of A. ameiva and raises the possibility that this species may act as a short‑distance seed disperser, contributing to ecological interactions in understudied habitats such as WSEs.

Predation of Amphisbaena darwinii (Duméril and Bibrón, 1839) by Phalotris lemniscatus (Duméril, Bibrón, and Duméril, 1854): a contribution to trophic interaction data in squamate reptiles
type: item
description: Detailed natural history records constitute a fundamental basis for calibrating complex ecological and evolutionary models. Here, we document a predator–prey interaction between the dipsadid snake Phalotris lemniscatus and the fossorial amphisbaenian Amphisbaena darwinii from southern Brazil. The snake ingested the amphisbaenian head‑first; the prey measured more than 50% of the predator’s total length and 68% of its body circumference, confirming the ability of P. lemniscatus to consume relatively large, elongate prey. The meticulous description of this event, together with explicit morphometric and ecological data, provides a crucial empirical record that helps address the Eltonian shortfall—the scarcity of documented species interaction data. Such records are essential for validating the ecological plausibility of interactions in food‑web models, refining evolutionary inferences about squamate diets, and highlighting the enduring value of scientific collections.

Polyandrous reproductive behavior of Boa constrictor Linnaeus, 1758 (Serpentes, Boidae) in the Brazilian Cerrado, Brazil
type: item
description: Here, we present the first record of polyandrous reproductive behavior in Boa constrictor within the Brazilian Cerrado. On 29 June 2024, at 11:00 h, three adult individuals (two males and one female) were observed engaging in mating behavior in a rural area of the municipality of Pereira Barreto, state of São Paulo. Sex was identified based on tail morphology. Both males copulated alternately with the same female, with no evidence of agonistic interactions. The event lasted approximately 30 minutes and occurred during the dry season, coinciding with the species’ reproductive period. Boa constrictor is viviparous, exhibits size‑dependent sexual maturity, and shows high ecological plasticity. This record expands current knowledge of the species’ reproductive biology in the Brazilian Cerrado.

First record of predation by Hoplias malabaricus (Characiformes: Erythrynidae) on Leptodactylus paranaru (Anura: Leptodactylidae) in the Atlantic Forest of southeastern Brazil
type: item
description: Hoplias malabaricus (Bloch, 1794) is a Neotropical predatory fish known for its generalist diet, which includes opportunistic consumption of amphibians. Leptodactylus paraná is a recently described anuran with a restricted distribution in the Atlantic Forest. This study reports the first record of predation by H. malabaricus on L. paraná, observed in a eutrophic stream in the municipality of Praia Grande, state of São Paulo, Brazil. We describe the interaction and discuss how environmental characteristics of the site may have facilitated the observation of the event. This record contributes to the knowledge of the natural history of both species and reinforces the opportunistic feeding behavior of H. malabaricus.

Saurophagy by Brazilian Anura: Trachycephalus mesophaeus (Hensel, 1867) and Itapotihyla langsdorffii (Duméril & Bibron, 1841) prey on Hemidactylus mabouia (Moreau de Jonnès, 1818)
type: item
description: Anurans play different roles in terrestrial and aquatic food chains and are generally described as opportunistic predators of invertebrates. However, some anuran groups also include vertebrates in their diet. In this study, we report two cases of predation on Hemidactylus mabouia, an invasive gecko species, by Itapotihyla langsdorffii and Trachycephalus mesophaeus, two anurans from the Atlantic Forest. On 27 October 2018, at 08:33 h, an individual of I. langsdorffii was observed preying on a juvenile H. mabouia on the external wall of a house in a rural property in the state of Rio de Janeiro, Brazil. The second case occurred on 26 February 2025, at 21:51 h, in the state of Santa Catarina, Brazil, when a T. mesophaeus was recorded preying on a H. mabouia on a sidewalk. Occasional observations of natural events such as these provide important information for increasing knowledge about interspecific interactions and expand what is known about the ecology and feeding biology of these groups.

Although attacks on humans are rare, most are interpreted as defensive responses. We report a non-fatal attack by Caiman latirostris in Jaboticatubas, Minas Gerais, Brazil. During a swimming training, the victim was attacked without prior visual detection of the animal. The event involved one bite to the trunk, followed by lateral head movements and contact with hind limbs and tail. After the victim’s defensive reaction, the animal released her, following her for approximately 50 m at the surface. Injuries included thoracic punctures and lacerations, abrasions on the lower limbs, and an axillary wound. The pattern of the …

Predation on a conspecific by Leptodactylus macrosternum Miranda-Ribeiro, 1926 (Anura: Leptodactylidae) in the southern Pantanal, Brazil
type: item
description: Anurans play an important role in food chains, acting both as predators and prey for several animal groups. Due to their opportunistic feeding habits, anurans may occupy a broad trophic niche, which can be influenced by factors such as food availability. The quantity and quality of food resources are affected by environmental variables, including the seasonal flooding regime of the Pantanal region. During the dry season, some anuran species may experience a reduction in trophic resources, which can lead to intraspecific predation. Here, we report an instance of in situ predation involving an adult Leptodactylus macrosternum preying on a conspecific juvenile in the southern Pantanal. The adult approached the juvenile and attempted to swallow the anterior portion of its body, leaving only the hind limbs protruding from the mouth. Such opportunistic and cannibalistic behaviors may be associated with ecological advantages, including the reduction of intraspecific competition and an increase in energetic gain.

These amphibians have developed physiological, morphological, and behavioral antipredatory adaptations, which have been primarily studied in Atlantic Forest species, resulting in significant knowledge gaps regarding Amazonian taxa. This study presents behavioral observations of three Amazonian anuran species, Adelphobates quinquevittatus, Dendropsophus marmarotus, and Rhaebo guttatus, in response to human approach and handling. These natural history records provide baseline data on the behavioral repertoires of these species.

First record of Dendropsophus anataliasiasi (Bokermann, 1972) (Anura, Hylidae) for the state of Pará, Brazil
type: item
description: This study reports the first record of Dendropsophus anataliasiae from the state of Pará, Brazil, in the municipality of Santana do Araguaia. This finding expands the known geographic distribution of the species, previously recorded in Cerrado areas approximately 229 km northwest of the type locality. The identification of the collected specimens was confirmed through morphological and genetic analyses. Morphologically, the individuals exhibited the diagnostic characters of the species, such as dorsal stripes, with slight variation in head measurements. DNA analyses corroborated the taxonomic identity, grouping the specimens with previously known sequences of the species. This record represents the 196th amphibian species documented for the state of Pará.

Primeiro registro de Rhinella pygmaea (Myers & Carvalho, 1952) para o município do Rio de Janeiro, RJ, e ameaças à sua conservação
type: item
description: Rhinella pygmaea is an endemic anuran of the Atlantic Forest in the states of Rio de Janeiro and Espírito Santo, which spends most of its life buried in sandy soils. Little is known about its natural history or the occurrence of populations within its distribution range, especially in areas subject to intense anthropogenic pressure due to human occupation. Here, we report the first record of a population in the municipality of Rio de Janeiro, at a locality that was theoretically protected within the Environmental Protection Area of the Serras de Inhoaíba, Cantagalo, and Santa Eugênia. After this record, part of the habitat occupied by this population was removed from the conservation unit by the Rio de Janeiro City Hall. The area was subsequently designated for the establishment of an urban park and other land uses, rendering the future of the species in the municipality uncertain.

Notes on the Natural History of Helicops leopardinus (SCHLEGEL, 1837) (Serpentes: Hydropsini) in a large urban center
type: item
description: Urban centers represent emerging socio‑ecological ecosystems that promote novel interactions, behavioral changes, and, consequently, new evolutionary trajectories. Population projections indicate that more than 60% of the world’s population will be living in urban areas by 2030, leading to habitat reduction and loss of space for wildlife. In this study, we investigated the diet and parasite ecology of an urban population of the water snake Helicops leopardinus. To this end, 50 individuals from scientific collections were analyzed. We recorded the first case of H. leopardinus consuming Nile tilapia (Oreochromis niloticus), which accounted for 50% of the total prey volume recorded. In addition, we documented the presence of cestode parasites of the genus Ophiotaenia, infecting 16% of the sampled individuals. These findings highlight the ecological flexibility of the species and contribute to a better understanding of wildlife responses to urban environments.

Predation of Eurolophosaurus aff. divaricatus (Sauria: Tropiduridae) by Philodryas nattereri (Serpentes: Colubridae)
type: item
description: This study reports the first record of predation on the lizard Eurolophosaurus aff. divaricatus, with the snake Philodryas nattereri as the predator. The event was observed on October 23, 2023, in the paleodunes of the São Francisco River, in Casa Nova municipality, Bahia, Brazil. We found an adult P. nattereri swallowing an adult E. aff. divaricatus inside a pitfall trap. As we approached, the snake quickly regurgitated its prey and escaped from the trap. Although E. aff. divaricatus has a restricted distribution, its local populations are relatively dense. Consequently, it is not surprising that P. nattereri preys on this lizard, given the relative abundance of E. aff. divaricatus and the generalist feeding habits and wide geographic distribution of this snake. This record highlights the incidental predation that can occur in pitfall traps and emphasizes the importance of frequent trap monitoring to minimize such events, particularly in areas of high endemism.

Defensive behavior of Adelophryne nordestina (Anura: Eleutherodactylidae) in an Atlantic Forest fragment in Northeast Brazil
type: item
description: Predation is one of the most significant selective pressures affecting survival in nature, compelling species to develop crucial defense strategies. Anurans exhibit a diverse repertoire of defensive behaviors aimed at safeguarding individuals across various stages of predation, but the roles of these behaviors differ among species. This study documents defensive behaviors observed in the miniaturized frog Adelophryne nordestina. We observed mouth gaping and death feigning behaviors in a small subset of the sampled individuals, without correlation between individual size and the defensive behaviors. Similar behaviors have been serendipitously observed in other species within the genus and among other miniaturized anurans. Given their low prevalence in this species, alternative defensive strategies such as cryptic coloration may play a more decisive role in species survival. Information about predators of A. nordestina is needed to clarify the role of each strategy in their predator-prey interaction.

And the Oscar goes to: Death-feigning behavior in Stenocercus squarrosus Nogueira & Rodrigues, 2006 (Squamata, Tropiduridae)
type: item
description: This study provides the first record of thanatosis (death-feigning behavior) in Stenocercus squarrosus, observed during a herpetofaunal inventory in the municipality of Caldeirão Grande do Piauí, state of Piauí, Brazil. Upon detecting the observer’s approach or following a slight touch, the individual rapidly fled approximately 10–15 cm before abruptly dropping to the ground, pressing its body dorsoventrally against the substrate, and extending its limbs alternately along each side of the body. Such a defensive display occurring without direct handling is particularly rare among lizards. This observation contributes novel behavioral information to the natural history of S. squarrosus, a species regarded as both elusive and rare.

Elementary survival strategy: first record of death-feigning behavior in Atractus pantostictus (Colubridae, Dipsadinae)
type: item
description: This study reports the first record of primary (crypsis) and secondary (behavioral) defensive strategies in a snake of the genus Atractus. During fieldwork conducted in Santana da Vargem, Minas Gerais, southeastern Brazil, a death-feigning (thanatosis) behavior was observed in an individual of Atractus pantostictus. The event allowed the documentation of a sequence of defensive responses exhibited by the snake. When gently touched, the individual initially remained motionless, then performed body contortions, and finally coiled its trunk while simulating death. The entire behavioral sequence lasted approximately twenty seconds and was followed by escape. This record expands the knowledge of defense mechanisms in fossorial species such as A. pantostictus. It contributes to the understanding of antipredator behaviors in the genus Atractus, whose natural history remains poorly known.

Are local crops home to frogs? A case study in the Ibiapaba Plateau, state of Ceará, Northeast Brazil
type: item
description: Studies investigating the impact of agricultural landscapes on amphibian diversity are crucial to understanding their consequences on amphibian population dynamics. Nevertheless, some environments, such as montane ecosystems, are still understudied. Herein, we describe the anuran composition in several agricultural landscapes of the Ibiapaba Plateau, Ceará State, Northeast Brazil. We performed anuran sampling in January and February 2019, with a total sampling effort of 154 hours by 3 researchers in 29 collection days. We found 170 individuals in 20 species and six families, of which 65% were found in the National Park of Ubajara, Ceará, Brazil. The anuran fauna was similar regardless of the crop type, and the Hylidae and Leptodactylidae had the highest species richness and abundance. Overall, we observed that these crops are usually homes for generalist frogs that are more adapted to disturbed environments. This will support awareness of public policies aimed at herpetofaunal preservation and conservation in this mountain due to the increase of anthropogenic disturbances in these areas.

Aprimorando o conhecimento sobre espécies exóticas por meio de mídias sociais: 34 novas localidades de ocorrência de Pantherophis guttatus (Serpentes: Colubridae) no Brasil
type: item
description: Utilizando uma abordagem de ciência cidadã que envolveu a combinação de dados obtidos por nós e informações de redes sociais, identificamos 34 novas localidades de Pantherophis guttatus no Brasil. Entre as três plataformas de ciência cidadã analisadas, o Facebook foi a única que retornou registros de P. guttatus no país, com a maioria (69,7%) proveniente do “Grupo do Biólogo Henrique”, atualmente o mais popular do Brasil relacionado à herpetologia. A região Sudeste concentrou a maioria dos registros (82,4%), o que pode ser explicado por fatores socioeconômicos e maior densidade populacional. O aumento expressivo de registros nos últimos dois anos (73,5% da amostra) pode sugerir um crescimento na quantidade de espécimes em vida livre, mas também pode ser resultado do aumento do número de usuários e grupos online relacionados à herpetologia. Dos registros levantados, 29,4% dos espécimes continuaram em vida livre, enquanto 38,3% foram encaminhados para órgãos competentes. No entanto, em ao menos um caso o espécime foi novamente posto em vida livre, atitude que decorre da falta de conhecimento para diferenciar espécies nativas de exóticas pelo público em geral. Finalmente, o ritmo cada vez mais acelerado de novos registros de P. guttatus evidencia a importância de iniciativas adicionais aos artigos científicos, como plataformas de ciência cidadã especializadas, para monitorar os avanços na distribuição de espécies exóticas no Brasil.

Etymology of American reptile genera
type: item
description: Here we provide the etymologies of all 416 extant reptile genera that occur on the American supercontinent, ranging from Canada to Argentina and Chile, but excluding the Caribbean. The 416 genera make up one third of all 1,250 reptile genera worldwide. Most of these names are still based on Greek and Latin terms (316 and 79, respectively), and about 20 names each are based on local terms, eponyms, and actual localities. The origin of some names remains mysterious (e.g. Farancia, Ficimia, Ninia), although we do offer speculations about them. More than half of all American reptile genera were coined by just 10 individuals, two of whom are still alive. The vast majority of names were coined in an intense period of discovery from around 1820 to 1880 (when many authors did not explain the origin of their names). However, a significant increase of new genus descriptions has begun in the 21st century with the advent of molecular taxonomy.
