Resumen

Approximately 41% of known amphibian species are at risk of extinction. Amphibians are even more vulnerable during their larval stages, as their skin is more permeable and more susceptible to absorbing environmental contaminants. There has been a significant increase in the number of studies on tadpoles in Brazil in recent years. Despite this increase, the number remains insufficient. Therefore, the objective of this research is to gather information about the current knowledge on tadpoles. To achieve this, a scientometric study was conducted, performing a non-automated systematic review of the available scientific literature. The research used the Web of Science and Google Scholar databases, with the descriptors “tadpoles” or “anuran larvae” covering publications from January 1960 to July 2024. Scientific articles, technical notes, and indexed books were included in this study. The analysis also aimed to identify Brazilian states with the highest number of publications and to analyze keywords using VOSviewer software. A total of 24,971 articles were found, of which 4,845 met the inclusion criteria. The USA had the highest number of publications (1,039), followed by Brazil (962), and China (291). Most worldwide articles mainly focus on specific families, such as Ranidae, Bufonidae, and Hylidae. In Brazil, 843 articles were valid, covering research on 17 families and 541 species, with Hylidae being the most studied (257 species; 46.9%), followed by Leptodactylidae (106 species; 19.3%), and Bufonidae (38 species; 6.9%). The families Alsodidae, Ceratophryidae, and Eleutherodactylidae were the least studied, with only one species each (0.0.1%). Most Brazilian studies are concentrated in the Southeast, especially in São Paulo, Minas Gerais, and Rio de Janeiro, while the North and Northeast regions have fewer publications. The analysis revealed patterns in research distribution, a growth in interest in tadpoles since 2010, and notable gaps in key areas that warrant further investigation.
