Abstract:

The genus Hannemania includes 25 species of parasites of amphibians; Chile has one species: H. pattoni Sambon, 1928. This work reviews the genus Hannemania and describes two new species from Chile: Hannemania ortizi sp. nov., a parasite of Pleurodema thaul (Lesson) (Anura: Leptodactylidae) and Eupsophus contulmoensis Ortiz, Ibarra-Vidal, Formas (Anura: Alsodidae) and Hannemania gonzaleacunae sp. nov., a parasite of E. nahuelbutensis Ortiz and Ibarra-Vidal (Anura: Alsodidae). The new species differ from H. pattoni and other nearby species principally by character states of the palp and leg seta

Abstract:

Ecological studies testing the preponderance of environmental filters on ontogeny to explain the variation in tadpole morphology are scarce for Neotropical anurans. We used tadpoles of the stone frog Limnomedusa macroglossa (Alsodidae): (1) to assess the variation in body and tail shape; (2) to examine the effect of streamlet depth and allometry on tadpole shape, and (3) to re-describe and compare the tadpole external morphology with closely related species. We obtained the body shape and size from 150 tadpoles. The re-description was based on 57 qualitative and 24 quantitative characters, fro

Abstract:

Resources are limited in global biodiversity conservation efforts, which emphasizes the significance of setting conservation priorities. Using standardized criteria, we evaluated 58 amphibian species in Chile to determine their conservation priority (CP). Species with insufficient historical data had their values marked as missing. With a median value of p = 1.67, the results demonstrated CP values ranging from p = 0.48 to p = 3.0, classifying species into priority and non-priority groups. Four levels were established for the priority categories: no priority, low priority, medium priority, and

Abstract:

Skin secretions from Patagonian ground frogs, Eupsophus vertebralis, have previously been reported as a potent proteinaceous adhesive with potential biomedical applications. Here, we conducted a rheological analysis indicating the mechanical robustness of these secretions, with a storage modulus ranging from 1 to 10 Pa. In addition, antimicrobial and cytotoxicity assays were performed, revealing no antimicrobial activity against both the Gram-positive and Gram-negative bacteria. The cytotoxicity results were intriguing, as three samples showed no harm, and one exhibited a severe cytotoxic effe

Abstract:

Intersexual morphological differences within a species occur in many traits, including body size and shape. Many processes that cause geographic variability in morphology have been proposed: population structure, phenotypic plasticity (environmental effects on development), and natural and/or sexual selection. Several hypotheses can explain patterns of sexual dimorphism in anurans, including natural or intra/inter-sexual selection, and differences in life history strategies between sexes. Limnomedusa macroglossa is considered a habitat specialist restricted to rocky outcrops in Brazil, Argenti

Given the relative independence resulting from the profound changes induced by metamorphosis, niche occupation and resource utilization in tadpoles may prompt evolutionary responses that do not necessarily affect the adults. Consequently, diversity patterns observed in the larval shape may not necessarily correspond to those found in the adult shape for the same species, a premise that can b

Abstract:

Alsodes pehuenche, an endemic anuran that inhabits the Andes of Argentina and Chile, is considered "Critically Endangered" due to its restricted geographical distribution and multiple potential threats that affect it. This study is about the natural history of A. pehuenche and the physicochemical characteristics of a breeding site located in the Maule mountain range of central Chile. Moreover, the finding of its clutches in Chilean territory is reported here for the first time. Finally, a description of the number and morphology of these eggs is provided.
