Molecular phylogeny and biogeographic history of the Neotropical tribe Glandulocaudini (Characiformes: Characidae: Stevardiinae) Neotropical Ichthyology
Camelier,Priscila; Menezes,Naércio Aquino; Costa-Silva,Guilherme José; Oliveira,Claudio.
ABSTRACT Although former studies on systematics and biogeography represent a progress on the knowledge of the tribe Glandulocaudini, none was grounded on molecular evidence. Thus, the first hypothesis of relationships for the tribe based on a multilocus analysis is presented, including all genera and most of the valid species. DNA sequences of Glandulocauda caerulea and Mimagoniates sylvicola were analyzed for the first time. A molecular clock analysis was used to estimate the origin of the Glandulocaudini and the approximate timing of cladogenetic events within the group. Glandulocaudini was recovered as monophyletic. No hypothesis recovered Glandulocauda as monophyletic, since G. melanopleura is sister to Lophiobrycon weitzmani while G. caerulea is...

Continental fishes from the Tambaba Environmentally Protected Area, Paraíba State, Brazil Pap. Avulsos de Zool. (São Paulo)
Ramos,Telton Pedro Anselmo; Carvalho-Rocha,Yuri Gomes Ponce de; Oliveira-Silva,Leonardo; Lustosa-Costa,Sílvia Yasmin; Ferreira,Paula Honório Pires.
Abstract Tambaba environmentally protected area is situated on the south coast of Paraíba State, within the Atlantic forest biome of the northeastern region in Brazil. The Tambaba environmentally protected area consists of a series of independent drainages: Graú, Mucatú, and Bucatú river micro-basins, and Caboclo River sub-basin that belongs to Gurugi River micro-basin. Ichthyological samples were collected in five scientific expeditions between months of June and July in 2015. Twenty-nine sites from different habitats (e.g., spanning tributaries, streams, rivers, and estuaries) were accessed for sampling. A total of 44 species distributed within 38 genera, 25 families, and 17 orders were assigned to the Tambaba hydrographic region. Freshwater species...
