Identification key for fishes from coastal streams of the Atlantic forest of southeastern Brazil

Abstract

In recent decades, current knowledge about fish from Neotropical streams has greatly increased, but is still deficient. Here we present an identification key for fishes from coastal freshwater streams from a large conservation area of Atlantic rainforest of southeastern Brazil, including 39 species. Considering that most of these species (61.2%) are endemic to the coastal streams, this identification key will be useful not only for the species recognition of the sampled area, but also for the surrounding coastal region.

Fish fauna from the estuaries of Ceará state, Brazil: a checklist in support of conservation of the Brazilian semiarid coast

“…Identification. Conspicuous sexual color dimorphism, males more colorful than females; pelvic fin of the mature males posteriorly displaced, its origin near the anal fin origin; females without developed urogenital papilla, and normally without spot in flank; first ray ofgonopodium serrated (Britski et al 1984;Gonçalves et al 2017).…”

Morpho-Molecular Discordance? Re-Approaching Systematics of Cambeva (Siluriformes: Trichomycteridae) from the Guaratuba-Babitonga-Itapocu Area, Southern Brazil

“…One of the most sampled areas in our recent field studies comprises the Rio Itapocu and the adjacent drainages that flow into the Baía de Babitonga and in the Baía de Guaratuba (hereafter the Guaratuba-Babitonga-Itapocu area, GBIA), corresponding to the north-eastern portion of Santa Catarina State, in southern Brazil. As in other regions located on the east side of the Serra do Mar, the coastal rivers rise with typical characteristics of mountain rivers and change to more slowly flowing when they reach the coastal plain [22]. Only Cambeva cubataonis (Bizerril, 1994) was formally described for GBIA [23], which is part of the Atlantic Forest, one of the most threatened and richest biomes on earth [24][25][26][27].…”

Biologia evolutiva e conservação de espécies da tribo Glandulocaudini (Characiformes: Characidae)

“…. Foram utilizados principalmente os livrosde Oyakawa et al (2006),Menezes et al (2007),Graça & Pavanelli (2007); os guias de identificaçãode Ingenito et al (2004), Baumgaurtner et al (2012,Malabarba et al (2013),Gonçalves et al (2017), Sarmento-Soares & Martins-Pinheiro (2019); e os artigos de composição da ictiofauna local de Carvalho et al (2012) e Bonato & Fialho (2016) e de revisão de nomenclatura do gênero Astyanax de Téran et al (2020). Cada população foi considerada como sendo representativa de cada espécie, para não incluir a variação intraespecífica nas análises.…”
