The behavioural context at which reproductive calls, other than advertisement call, are performed by anurans has been rarely studied in depth. Herein I describe in detail the vocalization behaviour of a frog whose voice was enigmatic until now. Amplectant and aggressive calls of the porthole frog Charadrahyla taeniopus (Günther, 1901) are described...

Amphibians are particularly sensitive to disturbances caused by urbanization. The urban disturbances impact amphibians in different ecological scales that include a decrease in biodiversity, increment of stress, and changes in vocal behavior. However, little is known about urban effects on terrestrial amphibians. In this study, we quantified abunda...

Alloparental care, i.e. care directed at non-descendant offspring, has rarely been described in amphibians. Rhinoderma darwinii is an Endangered and endemic frog of the temperate forests of Chile and Argentina. This species has evolved a unique reproductive strategy whereby males brood their tadpoles within their vocal sacs (known as neomelia). Sin...

On 17 January 2020 at 1210 h, we observed defensive behaviors of a E. calcaratus (23.3 mm SVL) during a predation attempt by the bird Scelorchilus rubecula (Rhinocryptidae). During a quick attempt of five pecks from the bird, the frog arched, inflating its body and stretching all four limbs to the ground, emitting up to three long, high-pitched squ...

Sexual signals in different animals are expected to be dimorphic when both sexes signal, but cases of monomorphism are known to occur, and we lack a clear understanding about the factors that modulate the level of sexual dimorphism in signals. In this study, we evaluated the hypothesis that the lack of dimorphism in sexual signals might evolve in s...

Darwin's frogs Rhinoderma darwinii and Rhinoderma rufum are the only known species of amphibians in which males brood their offspring in their vocal sacs. We propose these frogs as flagship species for the conservation of the Austral temperate forests of Chile and Argentina. This recommendation forms part of the vision of the Binational Conservatio...

Background. In animal reproductive contexts, calling behaviour is mostly performed by males but in species in which females call, it is not known how vocal interaction occurs between sexes, particularly when sexual dimorphism in signals is low, as in cases in which call repertoire is identical but acoustic properties differ. In Darwin’s frog ( Rhin...

Non-linear vocal phenomena (NLP) are complex phonation emissions that include complex frequency patterns, which have been reported in an increasing number of taxa. Such acoustic components may play an important role in signalling individual identity and motivation of emitters. Variations in NLP of distant populations within a species have not been...

In this study it was evaluated whether physical condition of a lizard is influenced by the structure of arboreal habitat used in foraging behavior during the dry season in a population of Palo Verde, Costa Rica. Although males were larger in size and weight, females had higher body condition. Habitat structure as well as differences in foraging beh...

The production of advertisement calls in sexual contexts is predominantly an attribute of males in anurans. Female calls occur in a small proportion of species in which these signals typically differ from those of males. The occurrence of such vocalizations has been related to sexual recognition prior to courtship. In the present study, we compared...

Amphibian conservation programs have traditionally procured pristine and innocuous conditions to ensure optimal captivity and the success of reintroduction plans. Furthermore, biolologists and conservationists ignore many of the interactions between the target species and their natural habitats. One of those species is the long-known axolotl Ambyst...

The nurse effect is a positive interaction in which one plant (the nurse) provides conditions that enhance the establishment and growth of another plant species (Callaway 1995). Increased environmental severity appeared to increase the strength of nurse effects (Brooker et al . 2008, Lortie & Callaway 2006). On the one hand, the impact of the nurse...

Recognition skills allow conspecific individuals to interact differently depending on their communication signals. In some cases the degree of relationship and the degree of similarity in acoustic signals are apparently closely related, which supports selectivity in the choice of partners or in the formation of social groups. Although frogs generally lack elaborated social structures, a recent study has shown that Darwin´s frog is a species in which individuals have restricted home ranges overlapping considerably among males with different reproductive success. The proposed study will evaluate the relevance of vocal interactions of Darwín’s frog for individual on the social structure of natural populations, using social networking tools. The study will test whether social interaction is determined by spatial association and vocal structure in R. darwinii.
Project
Pedregal ecosystem in the south valley of Mexico is one of the richest area in terms of biodiversity and endemism. The status and threats to this biodiversity is mainly related to urban sprawl, therefore involve the inhabitants of the city with the richness that dwelling within Pedregal reserves is an essential action for conservation. Our study proposes to improve the knowledge of the diversity and ecology of threatened amphibian species and promote their conservation within this ecosystem. We will conduct a vulnerability assessment to identify threats and conservation opportunities, and identify key sites for these species. We will visit the three biggest reserves of Pedregal to obtain information on species ecology, habitat and distribution. Outreach activities will be conducted to promote conservation actions with key decision makers and neighbors of the area. Further, we will develop a social media campaign to promote Pedregal's frog as a flagship of the south valley of Mexico. This project will generate a strong baseline of information on the ecology, threats and distribution of our focal species. Using this information we will work with reserve managers to develop effective on-going conservation actions.
