The brain of Brycon orbignyanus (Valenciennes, 1850) (Teleostei: Characiformes: Bryconidae): gross morphology and phylogenetic considerations

Neotropical Ichthyology
The brain of Brycon orbignyanus is described as a model for future studies of the gross morphology of the central nervous system in Characiformes. The study of brain gross morphology of 48 distinct taxa of Characiformes, one of Cypriniformes, two of ...

Comparative Mitochondrial Features Across Characiformes (Teleostei: Ostariophysi) and Mitogenomic Architecture of Nematobrycon lacortei

Diversity
Characiformes, a highly diverse group, are of great economic and ecological significance; however, their complex morphological convergence and adaptive radiation pose challenges to taxonomy, and phylogenetic controversies remain.

Description of the Early Development of Hoplias intermedius (Günther, 1864) (Characiformes: Erythrinidae). [PDF]

J Morphol
This study provides the first description of the early development of Hoplias intermedius (Characiformes: Erythrinidae), from the embryonic to the juvenile stage. The morphological, meristic, and morphometric characterization contributes to understanding the ontogeny and developmental transitions of Neotropical fishes, supporting taxonomy, conservation,

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA. [PDF]

J Fish Biol
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru. [PDF]

J Fish Biol
Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods. [PDF]

J Fish Biol
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...
