In aquatic environments, many prey animals, including anuran larvae, predominantly use chemical cues to assess predation risk. In such systems, a variety of chemical cues (e.g., kairomones, alarm, dietary) affect the behavioral responses of the prey tadpoles. Many anuran tadpoles are able to discriminate different chemical cues and exhibit differential antipredator behavioral responses according to the perceived risk. The behavioral responses of tadpoles of Clinotarsus curtipes to predatory larvae of the dragonfly Pantala flavescens were studied in the laboratory. The predator’s kairomones (water conditioned by a starved predator) or its diet-derived metabolites released in excreta of a predator after consumption of conspecific (C. curtipes) or heterogeneric (Indosylvirana temporalis) prey tadpoles were used to simulate predation threat. The tadpoles of C. curtipes had no behavioral response to predator kairomones. However, the tadpoles showed antipredator behavioral responses i.e., reduced swimming movements and overall time spent swimming, and had a higher burst speed in response to water-borne cues released from the excreta of predators fed both conspecific and heterogeneric prey. The antipredator behavioral responses of tadpoles were most intense in response to cues of predators fed on conspecific prey. The findings of the present study show that tadpoles of C. curtipes are capable of assessing levels of predation threat and modulating the intensity of their defense behavior in accordance with the perceived threat.

Pristimantis gutturalis is a species of the P. conspicillatus group described from French Guiana, with distribution so far restricted to the eastern Guiana Shield. Some aspects of this species are yet understudied, including its vocal repertoire which is unknown to date. Although in its original description it was properly characterized with regard to morphology, the description of its coloration in life consisted of brief remarks based on field notes on two females only. Moreover, little morphometric data were presented in its description, with detailed measurements provided for the holotype (a female) only. Subsequent studies have only briefly addressed this species and have not presented significant new data on it. In order to improve the knowledge on P. gutturalis, based on data from the state of Amapá, northern Brazil, in the present study we describe for the first time the advertisement and territorial calls of this species, assess its morphological and chromatic variation, provide detailed morphometric data on males and one female, and briefly comment on its natural history. Additionally, we compare the advertisement call of P. gutturalis with calls of other species of the P. conspicillatus group, and make some remarks on the acoustics of this group.

Oriental Sweetgum (Liquidambar orientalis) is a threatened tree species restricted to Rhodes Island (Greece) and southern Anatolia (Turkey), best known for its rare riparian forests. These small patches of forests are severely fragmented and scattered, and are rarely found in southwestern Turkey. Based on field sampling and data compilation, we performed an assessment of the herpetofauna in these forests in southwestern Turkey during the spring of 2019 and 2021. Sampling was carried out using a line-transect method in 13 forests with various habitats, resulting in data at the community and population levels. Sixteen families, including 26 amphibian and reptile species (four anurans, four turtles, nine lizards, and nine snakes), were recorded from these unique forests, based on 1440 individuals. Twenty-two species were recorded for the first time from these forests; in addition, Emys orbicularis and Elaphe sauromates were recorded for the first time from the region. Richness in the forest patches, habitat use by the recorded species, and interspecific interactions are discussed to explain the conspicuous patterns observed in the species distributions. The unique distribution pattern of Phoenicolacerta laevis among the existing forest patches represents the most prominent finding, with implications for a recent introduction. The fossorial species Xerotyphlops vermicularis, Blanus strauchi, and Eryx jaculus are unlikely to occur in the Oriental Sweetgum forest due to annual flooding. The data obtained during this study will be transferred to the Oriental Sweetgum forest conservation action plan (2019–2024) as part of the biodiversity monitoring tools for use in the long-term conservation of these forests.

The neotropical monotypic genus Macrogenioglottus, described to enclose M. alipioi, is a forest leaf litter frog with a wide geographic distribution in eastern Brazil, despite being considered a rare species. Herein, we present some reproductive data of this species from a population of the north of the São Francisco River, Northeastern Brazil. We present information on the amplexus, egg clutch, advertisement, and release calls, along with a description of its larval development. Adults were observed only after heavy and continuous rains, in a temporary pond located inside the forest. Males call in chorus at the edge of the pond. The advertisement call consists of a pulsatile single note, with no substantial variation in relation to the other population of the species, but which promptly differs this genus from the remaining Odontophrynidae. The amplexus is axillary. One female deposited 298 pigmented eggs in a plastic bag. The tadpole reaches its larger size at Stage 39, being the largest tadpole within the family. At the end of metamorphosis, the froglet snout–vent length is equivalent to tadpole total length at stage 26–27, indicating substantial postmetamorphic growth until adulthood. Data on body size of males and females are also provided. The uniqueness of some larval traits and mainly on some call attributes supports the systematic distinction of Macrogenioglottus.

Patterns of growth of crocodilians vary geographically within the same species, so models developed in one area may not predict size-age relationships in others. We used recapture data for three females and six males of Paleosuchus trigonatus from the Belo Monte hydroelectric dam area on the Xingu River to validate a growth model developed on a tributary of the Rio Negro. Individuals were recaptured between two and 10 years after marking (2012–2022). The data indicate that the monomolecular (von Bertalanffy by length) model is adequate to model growth of intermediate size animals. Recapture of one female after eight years indicates that the Rio Negro model can be used to model growth with accuracy for individuals from the Xingu River.

Physalaemus feioi is a South American frog endemic to the Brazilian Atlantic Forest that occurs in the states of Minas Gerais and São Paulo. We evaluated sexual dimorphism, female fertility, and diet of P. feioi from two locations in the state of Minas Gerais, including the type locality of the species. We collected 73 individuals (16 adult females and 57 adult males). The number of oocytes of P. feioi (x̅ = 1385 ±498.13) was higher than in other species of the genus, such as P. maculiventris, P. signifer, P. cuvieri, and P. ephippifer, but it resembles that of P. centralis, P. kroyeri, and P. marmoratus. The prey items with the highest index of importance were Coleoptera (IIR = 24.26) and Formicidae (IIR = 16.46). We found no sex differences regarding the number of ingested prey and the volume of the stomach contents. In summary, Physalaemus feioi was similar to other species of the genus regarding sexual dimorphism, fecundity, and feeding habits.
