Resumo

Observações e registros de história natural de répteis são fundamentais para a compreensão de sua ecologia, especialmente diante da rápida perda de habitat na Amazônia. Embora o lagarto teídeo Ameiva ameiva seja um forrageador ativo, com uma dieta amplamente documentada composta principalmente por artrópodes, existem registros de plasticidade alimentar que incluem o consumo de material vegetal. Neste estudo, documentamos a primeira observação de A. ameiva consumindo o fruto umari (Poraqueiba sericea) em um ecossistema de floresta inundável (EAB) na Amazônia Central, Brasil. O lagarto foi observado ativamente consumindo a polpa do fruto caído, sugerindo que o umari, rico em lipídios e carotenoides, pode servir como fonte energética alternativa ou suplementar. Esta observação amplia o conhecimento sobre a ecologia alimentar de A. ameiva e levanta a possibilidade de que a espécie atue como dispersora de sementes de curta distância, contribuindo para interações ecológicas em habitats ainda pouco estudados, como os EABs.

  • Anderson Lozorio

    Bachelor’s degree in Biological Sciences from the Federal Rural University of Rio de Janeiro (UFRRJ). Master’s degree in Tropical Forest Sciences, with an emphasis on Forest Ecology, from the National Institute of Amazonian Research (INPA). Currently a Ph.D. candidate in Zoology at the Federal University of Amazonas (UFAM). Scientific work focuses on the cranial osteology and functional morphology of aquatic caecilians (Gymnophiona: Typhlonectidae), using computed tomography (microCT), three-dimensional reconstructions, and comparative anatomical approaches to investigate patterns of morphological variation, ecological adaptations, and evolutionary implications. Also conducts research in the Natural History of Neotropical amphibians and reptiles, with an emphasis on predator–prey interactions and behavioral ecology.

  • Weslley Cunha

    Holds a Master’s degree in Zoology (UFAM, 2025) and a Bachelor’s degree in Biology (UFRA, 2021). His work focuses on assessing the effects of anthropogenic impacts on amphibian and reptile biodiversity. He serves as a technical development fellow at the Laboratory of Animal Evolution and Genetics (LEGAL), where he conducts studies evaluating species diversity in territories of traditional communities. He has experience with Ecological Niche Models and Species Distribution Models and is interested in landscape genomics approaches, aiming to understand how landscape transformation processes influence the evolutionary trajectories of anuran species.
