One of the most conspicuous species of Ambystoma in the Valley of Mexico is the Mountain Stream Siredon (Ambystoma altamirani Dugès, 1895), which is distributed in the Sierra de las Cruces, a mountain range that runs from the northwest part of the state of Mexico, south to western Mexico City and northwestern Morelos. Ambystoma altamirani is listed as endangered by the IUCN (IUCN 2022) and as threatened by the Mexican government (SEMARNAT 2019) (see Heredia-Bobadilla and Sunny 2021 for further discussion of conservation status). Throughout its distribution, this species is negatively affected by the introduction of Rainbow Trout (Estrella-Zamora et al. 2018, Guerrero de la Paz et al. 2020). Additional threats to populations of A. altamirani include urban sprawl associated with the growth of
墨西哥山谷中最引人注目的一种Ambystoma是Siredon山溪(Ambystoma altamirani dug， 1895)，它分布在塞拉·拉斯克鲁塞斯山脉，这是一条从墨西哥州西北部延伸到墨西哥城西部和莫雷洛斯州西北部的山脉。Ambystoma altamirani被世界自然保护联盟列为濒危物种(IUCN 2022)，并被墨西哥政府列为受威胁物种(SEMARNAT 2019)(见Heredia-Bobadilla和Sunny 2021以进一步讨论保护状况)。在整个分布过程中，该物种受到虹鳟鱼引入的负面影响(Estrella-Zamora等人2018年，Guerrero de la Paz等人2020年)。对altamirani种群的其他威胁还包括城市扩张与森林的生长

The influence of desiccation on metamorphic traits (larval duration and size at emergence) was studied in Polypedates maculatus under laboratory conditions. Gosner Stage 23 tadpoles were exposed to decreasing water levels (gradual or rapid) until the beginning of metamorphic climax (Stage 42). A control group was reared in constant water levels. Tadpoles reared in decreasing water levels reached the metamorphic climax earlier and metamorphosed at a smaller size than those reared in constant water levels. Further, tadpoles experiencing rapid depletion of water reached the metamorphic climax earlier and metamorphosed at a smaller size than those experiencing gradual depletion of water levels. Tadpoles of P. maculatus showed adaptive plasticity in metamorphosis to pond drying. Survival of tadpoles in treatments and the control was 100%. The study revealed that tadpoles of P. maculatus have plastic development in response to water levels; the trade-off between growth and development favors development, which results in early metamorphosis at a small size.

In anurans, advertisement calls are typically emitted during breeding seasons by adult males to attract females and to convey a territorial signal to conspecific males (Wells 2007, Toledo et al. 2014, Köhler et al. 2017). Vocalizations may provide species-specific information useful for taxonomic and systematic assessments because they act as a premating isolating mechanism and may thus carry a phylogenetic signal (Köhler et al. 2017). Moreover, studying the vocalizations of frogs and toads enhances a more comprehensive understanding about their population and distribution dynamics, allowing for the acoustic monitoring of targeted species (Teixeira et al. 2019). Pristimantis unistrigatus (Günther, 1859), also known as “Cutín Quiteño”, is a small frog (SVL: males = 14.9–28.8 mm; females = 22.5– 38.5 mm) that occurs at high elevations (2200

Pseudoeurycea jaguar Cázares-Hernández, Jimeno-Sevilla, Rovito, López-Luna, and Canseco-Márquez, 2022 is an endemic species of plethodontid salamander that occurs in Veracruz, Mexico. Pseudoeurycea is the most speciose genus (40 spp.) and Plethodontidae is the largest family (88% of salamander richness) present in the country (AmphibiaWeb 2023). Eleven species of Pseudoeurycea occur in the state of Veracruz (Torres-Hernández et al. 2021, CázaresHernández et al. 2022), where the type locality in the Sierra de Zongólica of P. jaguar is located. Pseudoeurycea jaguar is distinguished from other species occurring in Veracruz by its large size and the presence of irregular yellow mottled dorsal coloration on a dark brown, almost black, background that resembles the pattern of a jaguar (Cázares-Hernández et al. 2022).

Following the observation of adult pairs of the Western Whipsnake, Hierophis viridiflavus, in a controlled environment, two distinct but related phenomena were observed: egg deposition and predation of freshly laid eggs by the male. Data about deposition, number and morphology of the eggs, hatching and offspring are presented and compared with the literature. The episode of oophagy is described, confirming the inclination to predate snake eggs and intraspecific oophagy in this species.

Bothrops asper (Garman, 1883), a large, dietary generalist viper, is the only lancehead species widely distributed in the humid lowlands of Middle America and northwestern South America (Sasa et al. 2009, Saldarriaga-Córdoba et al. 2017). The species exhibits cryptic habits and adapts very well to disturbed environments such as agricultural areas (Sasa et al. 2009). These features, added to its high prolificacy, make B. asper responsible for the highest snakebite incidence throughout its distribution (Sasa et al. 2009). It is not surprising that it is a snake of great medical importance that has monopolized epidemiological and toxicological studies in the region (Saldarriaga et al. 2003, Alape-Girón et al. 2008, Bravo-Vega et al. 2019).

The behavioral responses of laboratory-reared and wild-caught tadpoles of Polypedates maculatus to predatory tadpoles of Hoplobatrachus tigerinus were studied in the laboratory. The predator’s diet-derived metabolites released in excreta of predator after consumption of P. maculatus tadpoles were used to simulate predation threat. Both laboratory-reared and wild-caught tadpoles of P. maculatus showed antipredator behavioral responses i.e., reduced swimming movements and overall time spent in swimming and had a higher burst speed in response to water borne dietary cues of predators. Further, the antipredator responses of wild-caught tadpoles were significantly higher than those exhibited by laboratory-reared tadpoles. The studythus shows that antipredator behavior in these tadpoles is innate. Further, an enhanced antipredator behavior of wild-caught tadpoles may suggest their prior experience with predators in natural waters.
