Article
The present study predicts that helminth community diversity and parasite transmission are influenced by host behavior and its habitat. This prediction was tested by analyzing for the first time the helminth community of Lepidobatrachus llanensis, an aquatic species that inhabits exclusively ephemeral water bodies in the Dry Chaco ecoregion. In the...

RESUMEN En la Región Oriental del Paraguay se encuentran los humedales del Complejo Ypoá, declarados como sitio RAMSAR y categorizados como Reserva de Recursos Manejados. Pese a estas categorías de protección, su biodiversidad ha sido escasamente estudiada. El objetivo de este trabajo fue determinar la riqueza, composición y abundancia de anuros y...

Studies on the exploitation of trophic resources allow to establish interactions between predators and predator-prey, and this dynamic can present fluctuations over time and space. We analysed stomach contents of 19 anuran species from tropical dry forests of Colombia, quantified the overlap between species and identified anuran trophic guilds. Mos...

Melanophryniscus paraguayensis (no common name) is an endemic toad of the central grasslands in the eastern region of Paraguay. Details about its natural history are poorly understood and it is categorized nationally as Vulnerable. This work describes the diet composition of this species and the relationship between toad body size and the number an...

This is the first review of the nematode parasites of amphibians from Dry Chaco (DC) and Humid Chaco (HC) ecoregions of South America, covering aspects related to their systematics, distribution, host range and ecology, including their life cycles. Of approximately 100 species of amphibians that inhabit these ecoregions, the nematode parasites of 3...

In the Argentinean Gran Chaco, numerous investigations have dealt with the diversity of vertebrates , including amphibians and reptiles. The parasitofauna of these organisms, has been more studied in some groups such as amphibians; however, from a biogeographic perspective, most of these studies were carried out in the Humid Chaco. The goal of this...
Article
Species of Bufonidae and Leptodactylidae are common in the Colombian tropical dry forest. Although some of them are associated with active foraging and consumption of termites and ants, their trophic ecology is mostly unknown. The diet of five anuran species of Bufonidae (Rhinella horribilis, R. humboldti) and the leptodactylid subfamily Leiuperina...
Article
en Anuran–prey selection might be mediated by traits, either by mismatches in predator and prey traits (preventing interactions) or by predator selection of prey traits (encouraging interactions). These effect traits could be summarized in two contrasting foraging strategies: “active” and “sit‐and‐wait” foragers. We evaluated whether anurans could...

The present study describes the helminth community collected from juveniles of Dermatonotus muelleri (Anura: Microhylidae) from the Chaco Seco Ecoregion. Helminths were found in 80.0% of specimens examined (n = 16). The helminth community of this microhylid presented very low species richness; a total of 1,339 specimens belonging four helminth spec...

Abstract. We describe the diet of two syntopic Scinax species, S. rostratus and S. ruber, from northern lowlands of Colombia. These frogs do not seem to exhibit a marked preference for the consumption of a particular type of prey. However, in their diets, orthopterans were a well-represented category. Scinax ruber showed a positive and significant...

The diet of 2 species of Elachistocleis in the lowlands of Northern Colombia is described. Due to the characteristics of their diet (composition, volume, average number of prey per stomach, and the records of another related species) E. pearsei and E. panamensis are active foragers, and termite-and ant-eating specialists.

We characterize the diet of Craugastor raniformis, a terrestrial frog that inhabits the tropical dry forest in Colombia. The diet is constituted mostly of orthopterans, millipedes, arachnids and ants. Considering the morphological characteristics of this species, diet composition, gut vacuity index, trophic niche breadth and diversity, we consider...

We describe the vocal repertoire of Melanophryniscus cupreuscapularis, a bufonid toad of the Melanophryniscus stelzneri species group, which has been recently listed as “Vulnerable” by the Asociación Herpetológica Argentina. Recordings were obtained in “Paraje El Perichón,” a relict of Schinopsis balansae “quebracho” forest near Corrientes City, Ar...
Article
The ability of an organism to produce different phenotypes under different environmental conditions is a common adaptation in nature. Biotic factors like competition, community structure and predation can influence the survival and time to metamorphosis in amphibians. However, abiotic factors such as the hydroperiod and light intensity can be as im...

In environments with thermal and pluvial seasonality such as those of the Middle Paraná River floodplain (Province of Santa Fe, Argentina), most amphibian species reproduce during the warm season and drastically diminish their activity during winter. Even though, a few species remain active during the cold season, such as Hypsiboas pulchellus that...

A más de una década de la primera Lista Roja de herpetofauna propuesta por la Asociación Herpetológica Argentina (Lavilla et al., 2000), se recategorizaron los anfibios a partir de nueva información taxonómica, biogeográfica, bio-ecológica y de modificaciones metodológicas respecto a la evaluación anterior. Mediante la participación de 35 especiali...

We studied the trophic ecology of Dendrobates auratus and Oophaga pumilio in La Selva Biological Station, Costa Rica. At this site, both dendrobatids are sympatric due to the introduction and naturalization of D. auratus in the last 24 years. Diets of both dendrobatids were recorded by the analysed stomach flushing technique. Microhabitats uses wer...
