Molecular phylogeny of the tribe Philodryadini Cope, 1886 (Dipsadidae: Xenodont...
Arredondo, Juan Camilo; Grazziotin, Felipe Gobbi; Scrocchi Manfrini, Gustavo Jose; Rodrigues, Miguel Trefaut Urbano; Bonatto, Sandro LuísSouth American racers of the tribe Philodryadini are a widespread and diverse group of Neotropical snakes with a complex taxonomic and systematic history. Recent studies failed to present a robust phylogenetic hypothesis for the tribe, mainly due to incomplete taxon sampling. Here we provide the most extensive molecular phylogenetic analysis of Philodryadini available so far, including 20 species (83% of the kn...
Mites and ticks of reptiles and amphibians in Brazil
Mendoza-Roldan, Jairo; Ribeiro, Stephany Rocha; Castilho-Onofrio, Valeria; Grazziotin, Felipe Gobbi; Rocha, Bruno; Ferreto-Fiorillo, BrunoMade available in DSpace on 2020-12-12T01:23:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-08-01; This study focuses on the parasitic associations of mites and ticks infesting reptiles and amphibians through a multifocal approach. Herein, reptiles (n= 3,596) and amphibians (n= 919) were examined to ensure representativeness of the Brazilian herpetofauna megadiversity. The overall prevalence was calc...
Molecular phylogeny of advanced snakes (Serpentes, Caenophidia) with an emphasi...
Zaher, Hussam; Grazziotin, Felipe Gobbi; Cadle, John E.; Murphy, Robert W.; Moura-Leite, Julio Cesar de; Bonatto, Sandro L.We present a molecular phylogenetic analysis of caenophidian (advanced) snakes using sequences from two mitochondrial genes (12S and 16S rRNA) and one nuclear (c-mos) gene (1681 total base pairs), and with 131 terminal taxa sampled from throughout all major caenophidian lineages but focussing on Neotropical xenodontines. Direct optimization parsimony analysis resulted in a well-resolved phylogenetic tree, which...
