Effects of pasture-burning management on anuran communities in subtropical Brazilian grasslands Guilherme Cansan, Camila Fernanda Moser, Juliano Morales de Oliveira, Alexandro Marques Tozetti Biotropica, 2025 Anthropogenic fire is a worldwide event that affects many ecosystems and organisms. In Southern Brazil, grassland management with fire has been highly employed since the mid‐18th century. Although the practice is regulated by federal law (prescribed fire), there is no detailed information about the impacts of this practice on the small, non‐volant fauna. We evaluated the effect of fire management on anuran species richness and community composition in Brazilian grassland areas that have adopted this practice for more than 15 years. Our results show that burning practices lead to a reduction of anuran richness. About 37% of the species occur exclusively in sites free of fire. Sites with fire management have low densities of taller grass and shrubs, which could reduce habitat availability for some anuran species. Nestedness and turnover components of beta diversity did not differ within and between treatments, but there was a tendency for a nestedness organization of the community in burned sites, suggesting that sites with fire management are a subsample of sites where fire is absent. Our results pointed out that prescribed fire practices have potentially negative effects on the anuran diversity. These results suggest that the changes in vegetation, in particular percentages of shrub cover, affect habitat suitability for some species. Therefore, anuran communities tend to become less diverse and lack arboreal species where fire occurs.Abstract in Portuguese is available with online material.
Effects of grassland controlled burning on symbiotic skin microbes in Neotropical amphibians Laura K. Schuck, Wesley J. Neely, Shannon M. Buttimer, Camila F. Moser, Priscila C. Barth, Paulo E. Liskoski, Carolina de A. Caberlon, Victor Hugo Valiati, Alexandro M. Tozetti, C. Guilherme Becker Scientific Reports, 2024 Climate change has led to an alarming increase in the frequency and severity of wildfires worldwide. While it is known that amphibians have physiological characteristics that make them highly susceptible to fire, the specific impacts of wildfires on their symbiotic skin bacterial communities (i.e., bacteriomes) and infection by the deadly chytrid fungus, Batrachochytrium dendrobatidis, remain poorly understood. Here, we address this research gap by evaluating the effects of fire on the amphibian skin bacteriome and the subsequent risk of chytridiomycosis. We sampled the skin bacteriome of the Neotropical species Scinax squalirostris and Boana leptolineata in fire and control plots before and after experimental burnings. Fire was linked with a marked increase in bacteriome beta dispersion, a proxy for skin microbial dysbiosis, alongside a trend of increased pathogen loads. By shedding light on the effects of fire on amphibian skin bacteriomes, this study contributes to our broader understanding of the impacts of wildfires on vulnerable vertebrate species.
Predator morphology affects prey consumption: evidence from an anuran population in subtropical wetlands Camila Maria Mendonça da Silva, Diego Anderson Dalmolin†, Laura Kauer Schuck, Camila Fernanda Moser, Alexandro Marques Tozetti Herpetological Journal, 2024 Morphology and diet are key factors in the ecology of organisms, determining aspects of the natural history and evolution of the species. In this work, we evaluated the diet-morphology relationship in an anuran population, measuring the influence of morphological traits on the variation in the diet of individuals of Leptodactylus luctator. For this purpose, we collected individuals from a natural grassland habitat in southern Brazil. We analysed the stomach content of individuals and classified the consumed food items up to the classification level of order. We also measured four morphological traits per individual of L. luctator: distance between eyes, relative limb length, relative mouth width (gape) and snout-vent length. We applied Linear Mixed Effect Models to evaluate the relationship of anuran morphological traits, number of prey taxa and volume of consumed prey. We tested the hypothesis that the configuration of predator morphological traits determines variations in prey consumption patterns. Our results indicate that the body size of L. luctator was not directly related to the diet composition but the individuals’ gape is directly and positively related to the number of consumed taxa. This suggests that gape limitation could be a limiting factor in prey selection. The capacity to consume a wide variety of prey taxa could be an advantage in unpredictable environments, especially those with great daily thermal amplitudes such as the subtropical Brazilian grasslands.

The release call of Dendropsophus sanborni (Anura: Hylidae), with comments on release calls within Dendropsophus Laura Kauer Schuck, Camila Fernanda Moser, Renata Krentz Farina, Daniela Figueiró, Alexandro Marques Tozetti, Rodrigo Lingnau Caldasia, 2024 Release calls are a non-receptive response to amplexus between different species or conspecific amplexus between males. This call differs between closely related species and can be an important tool for the taxonomy of this group. Here, we describe, for the first time, the release call of Dendropsophus sanborni (Schmidt, 1944) from a record during a field trip in a palm grove in southern Brazil. We recorded two release calls from a male individual of D. sanborni while handling it. These release calls are simply formed by one note with no modulation. Release calls of Dendropsophus are poorly reported in the literature, and comparisons among them are limited. Release calls are possibly much more common than reported in the literature and more description studies are needed.
The role of artificial ponds for anuran diversity in managed areas of the Atlantic Forest Jackson Preuss, Diego Anderson Dalmolin, Camila Fernanda Moser, Diego Brum, Elaine Maria Lucas, Mauricio Roberto Veronez, Maria João Ramos Pereira, Alexandro Marques Tozetti Studies on Neotropical Fauna and Environment, 2024 Artificial ponds can be important reproductive sites for anurans in human-disturbed habitats. However, this capacity depends on the configuration of the habitat where they are inserted. We evaluated how anuran beta diversity was influenced by the configuration of the surrounding habitat and water parameters in artificial ponds in southern Brazil. Physicochemical parameters of water and the configuration of the surrounding habitat were the elements that best explained the variation in beta diversity. However, the surrounding habitat had a predominant role in the differences between communities. The level of exposed soil was the component that best acted on the turnover component of beta diversity followed by urbanization, which highlights the impact of human presence on anuran diversity. In other words, we observed that anthropogenic changes caused changes in species composition in the evaluated ponds. Among water parameters, only phosphate was relevant for the configuration of communities. Phosphate peaks may result from sewage or fertilizer contamination, not infrequent in the region despite the low human density and the small-scale agriculture economy. Even though they are anthropogenic environments, artificial ponds can help maintain the anuran communities, but their effectiveness will depend on the presence of forest remnants and water quality.
