Biologia reprodutiva e alimentar de dendrophidion dendrophis (fitzinger, 1843) (reptilia, serpentes, colubridae) da Amazônia Oriental, Pará, Brasil.

Dendrophidion dendrophis is a semi-arboreal species, characterized by a slightly compressed, slender body and long tail. In Brazil, it is present in the eastern portion of the Amazon, and can be found foraging actively on the soil of primary and secondary forests. This work aims to provide data on t...

Pereira, Carlos Eduardo Yamashina Prudente, Ana Lúcia da Costa Dendrophidion dendrophis Reptilia Serpentes Colubridae CNPQ::CIENCIAS BIOLOGICAS::ZOOLOGIA::FISIOLOGIA DOS GRUPOS RECENTES Dendrophidion dendrophis is a semi-arboreal species, characterized by a slightly compressed, slender body and long tail. In Brazil, it is present in the eastern portion of the Amazon, and can be found foraging actively on the soil of primary and secondary forests. This work aims to provide data on the reproductive and feeding biology of this species. We analyzed 89 specimens (55 males and 34 females) from the Herpetological Collection of the Museu Paraense Emílio Goeldi, Belém, Pará, Brazil. Six morphometric and meristic variables were considered in the study of sexual dimorphism. The gonads and stomach contents were examined by abdominal incision. Males were considered mature if the duetos deferens were tangled and/or opaque, and females with secondary vitellogenic follicles (> 10mm), eggs, enlarged oviduct or with egg marks. Nestlings were considered to be individuals with umbilical scar, and juveniles individuals with immature gonads. The food items were identified and the direction of prey ingestion was observed. Females presented a greater total length than males. However, sexual dimorphism was not observed in the number of ventral, sub-caudal, rostro-cloacal (CRC) and caudal lengths. Smallest male and smallest female mature with CRC 456 and 445 mm, respectively. The reproductive cycle of females is asseasonal, with eggs present throughout the year. It was observed that the higher the CRC of the female, the greater the length and thickness of the vitellogenic follicles and eggs. It was confirmed that it is an exclusively anurophagous species (including species of Adenomera, Physalaemus and Pseudopaludicola), with ingestion predominantly in the posteroanterior direction. Dendrophidion dendrophis é uma espécie semi-arborícola, caracterizada por apresentar corpo levemente comprimido, delgado e cauda longa. No Brasil, está presente na porção Oriental da Amazônia, podendo ser encontrada forrageando ativamente no solo de florestas primárias e secundárias. Este trabalho tem como objetivo fornecer dados sobre a biologia reprodutiva e alimentar desta espécie. Foram analisados 89 espécimes (55 machos e 34 fêmeas) da Coleção Herpetológica do Museu Paraense Emílio Goeldi, Belém, Pará. No estudo de dimorfismo sexual foram consideradas seis variáveis morfométricas e merísticas. As gônadas e conteúdo estomacal foram examinados através de incisão abdominal. Foram considerados maduros machos com duetos deferentes enovelados e/ou opacos, e fêmeas com folículos vitelogênicos secundários (> 10mm), ovos, oviduto alargados ou com marcas de ovos. Foram considerados filhotes indivíduos com cicatriz umbilical, e jovens indivíduos com gônadas imaturas. Os itens alimentares foram identificados sendo observado sentido de ingestão das presas. Fêmeas apresentaram comprimento total maior que machos. Entretanto, não foi observado dimorfismo sexual no número de ventrais, subcaudais e comprimento rostro-cloacal (CRC) e caudal. Menor macho e menor fêmea maduros com CRC 456 e 445 mm, respectivamente. O ciclo reprodutivo das fêmeas é assazonal, com a presença de ovos ao longo de todo o ano. Observou-se que quanto maior o CRC da fêmea, maior o comprimento e espessura dos folículos vitelogênicos e dos ovos. Confirmou-se que é uma espécie exclusivamente anurofágica (incluindo espécies de Adenomera, Physalaemus e Pseudopaludicola), com ingestão predominantemente no sentido póstero-anterior 2023-05-15T18:14:34Z 2023-05-15 2023-05-15T18:14:34Z 2005-06-30 Resumo PEREIRA, Carlos Eduardo Yamashina; PRUDENTE, Ana Lúcia da Costa.
