Abstract
Many species of Neotropical frogs have evolved to deposit their tadpoles in small water bodies inside plant structures called phytotelmata. These pools are small enough to exclude large predators but have limited nutrients and high desiccation risk. Here, we explore phytotelm use by three common Neotropical species: Osteocephalus oophagus, an arboreal frog that periodically feeds eggs to its tadpoles; Dendrobates tinctorius, a tadpole-transporting poison frog with cannibalistic tadpoles; and Allobates femoralis, a terrestrial tadpole-transporting poison frog with omnivorous tadpoles. We found that D. tinctorius occupies pools across the chemical and vertical gradient, whereas A. femoralis and O. oophagus appear to have narrower deposition options that are restricted primarily by pool height, water capacity, alkalinity, and salinity. Dendrobates tinctorius tadpoles are particularly flexible and can survive in a wide range of chemical, physical, and biological conditions, whereas O. oophagus seems to prefer small, clear pools and A. femoralis occupies medium-sized pools with abundant leaf litter and low salinity. Together, these results show the possible niche partitioning of phytotelmata among frogs and provide insight into stressors and resilience of phytotelm breeders.

We are grateful to the staff of Nouragues Ecological Research Station (managed by CNRS), which benefits from ?Investissement d'Avenir? grants managed by Agence Nationale de la Recherche (AnaEE France ANR-11-INBS-0001; Labex CEBA ANR-10-LABX-25-01), for logistic support in the field and for providing the meteorological data. Thank you to Rick Lehtinen and L.M. Schulte for their constructive and insightful reviews, which greatly contributed to the quality of this manuscript. This work is part of a partnership between BR, AP, and the Nouragues Nature Reserve aimed at improving and spreading the knowledge about amphibians. We thank the staff of the Nouragues Nature Reserve for their commitment to preserving our natural world; Walter H?dl for his ongoing mentorship and inspiration of this work and collaboration; Valentine Alt for the essential canopy access training and equipment; and Lauren A. O'Connell for her generous support of AP, SJSR, and MTF. A huge grazie mille to Matteo Vecchi for being patient in teaching CF how to truly attack a PCA with all of the statistical might humanly possible. The authors highly value equity, diversity, and inclusion in science. We cherish the international and diverse nature of our team, which includes researchers from (7) different countries, backgrounds, and career stages, as it significantly contributed to the fulfillment and quality of the present study.
