Distribution and Habitat
This species was featured in News of the Week 5 June 2023:
Foam nests are a unique reproductive strategy used by frogs providing eggs and larva protection from desiccation, predation, and suffocation while also aiding in fertilization and providing a food source for developing larvae. More recently, the protein and carbohydrate rich foam also has been associated with the vertical transfer of beneficial microbial communities in rhacophorid frogs. Monteiro et al. (2023) characterized the protein composition and microbiome of the nests of three Leptodactylid species: Adenomera hylaedactyla, Leptodactylus vastus, and Physalaemus cuvieri, with each representing a different spawning habitat type. They found that protein composition was species-specific and was influenced more by spawn habitat type and nest size than phylogenetic relatedness. Many of these proteins were previously unidentified. Additionally, the microbiome community of the nest was unique from the surrounding environment and the adult skin microbiome. These findings show that foam nests have a key functional role in reproduction and highlight the need for conservation efforts to protect nests from anthropic pressures, as each nest has a unique microenvironment.
