Diet of tadpoles for five anuran species of northeast Brazil
Diet of tadpoles to five anuran species
In this study, the diet of tadpoles of five anuran species was described. The species were collected from either lotic or lentic environments in Caatinga and the Atlantic Forest biome of northeast Brazil. The diet of these tadpoles consisted of algae, protozoa, plants, fungi and animals. Diatoms were the most important items within the diet of Leptodactylus natalensis. Trachelomonas, diatoms, Phacus and Scenedesmus were the most important items comprising the diet of Leptodactylus cf. macrosternum. Trachelomonas, Oscillatoria and Scenedesmus were the most important items comprising the diet of Pithecophus nordestinus. Diatoms and Scenodesmus were the most important items of the diet for Rhinella jimi. For Scinax x-signatus, diatoms (Atlantic Forest population), Oscillatoria, undetermined filament and pollen (Caatinga population) were the most important items consumed. Scinax x-signatus and L. natalensis from Atlantic Forest, and L. cf. macrosternum and P. nordestinus from Caatinga had diets that were the most similar. The diversity of items found in the diets of species considered may be attributed to mechanisms used by tadpoles to obtain food, which favour the acquisition of suspended materials that are highly available in the environment. We discuss the possible effects of the relationship between algae and tadpoles and the importance of recording larvae diets to better understand the dynamics of the aquatic environment and the trophic ecology of tadpoles.
PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
