What the largest tadpole feeds on? A detailed analysis of the diet composition of Pseudis minuta tadpoles (Hylidae, Dendropsophini) [PDF]

Anais da Academia Brasileira de Ciências, 2016
We analyzed the diet of 25 individuals of Pseudis minuta tadpoles which consisted in debris with more than 30%, follow by diatoms, euglenids, green algae, and desmids. With regard to the feeding strategy, P. minuta tadpoles are generalist consumer.

Gonadal Development in Larvae of the Paedomorphic Ambystoma mexicanum (Amphibia: Urodela). [PDF]

J Morphol
This research analyzes the gonads of Ambystoma mexicanum larvae of both sexes, revealing significant changes such as the onset of vitellogenesis in females at 9 months of age and oocytes with signs of maturity at 12 months. In males, gonadal maturity occurs earlier, with a notable cephalocaudal and lateromedial testicular regionalization, and ...

Meal or mate: Exploring the evidence of sexual cannibalism among amphibians. [PDF]

Ecol Evol
Sexual cannibalism is a form of conspecific predation among adults, typically committed by females that consume potential or actual mating partners. We provide an observation of cannibalism involving an adult female green and golden bell frog, Litoria aurea, preying on a conspecific adult male during the species' breeding season.

American bullfrog (Lithobates catesbeianus) distribution, impact on native amphibians and management priorities in San Carlos, Uruguay

Knowledge and Management of Aquatic Ecosystems, 2023
Biological invasions are a major cause of biodiversity and ecosystem services loss. However, information on distribution and impacts is limited for many alien species, restricting the development of local management measures. The aim of this study is: to

The role of phytophysiognomies and seasonality on the structure of ground-dwelling anuran (Amphibia) in the Pampa biome, southern Brazil

Anais da Academia Brasileira de Ciências, 2013
Considering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure.

Coloration of Anuran Tadpoles (Amphibia): Development, Dynamics, Function, and Hypotheses

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Colorations of anuran tadpoles surely function in many of the same ways that have been ascribed to color and pattern in other animals, but the paucity of data forces one to look to other groups to generate hypotheses. Such an action often occurs because of the difficulty of defining specific fitness parameters to larval forms.

The activity patterns and microhabitat use of Pseudis minuta Günther, 1858 (Anura, Hylidae) in the Lagoa do Peixe National Park, a biosphere reserve of the brazilian subtropics

Brazilian Journal of Biology
Pseudis minuta is abundant in a variety of aquatic environments of the Pampa domain. Therefore, it can be considered a good model for testing hypotheses on environmental heterogeneity and the influence of climate on the activity of anurans. In this study,

Description and shaping factors of diet and feeding ecology of neotropical tadpoles: A case study and a comprehensive review

Austral Ecology, Volume 49, Issue 1, January 2024.
We performed a systematic review on the available literature on in situ studies of neotropical tadpole diets focusing on diet composition and its sources of variation. Such studies approached in just a few instances the effects of seasonality, developmental stage and food selectivity on diet composition, but the available data indicate none of these ...
