Molecular variants in populations of Bryconamericus aff. iheringii (Characiformes, Characidae) in the upper Paraná river basin - doi: 10.4025/actascibiolsci.v35i2.11451

open access: yesActa Scientiarum: Biological Sciences, 2012
There are evidences that Bryconamericus aff. iheringii represents a species complex. DNA molecular markers have been effective in studies on phylogeny, taxonomy, and identification of cryptic species. In this study, partial sequences of genes of ATPase 6

Karyotypic diversity in a population of Bryconamericus aff. iheringii (Characidae)

open access: yesGenetics and Molecular Research, 2014
Bryconamericus comprises 56 species distributed into three groups, on the basis of the position and shape of the maxillary teeth: B. exodon, B. microcephalus and B. iheringii groups. Few cytogenetic data are available for this genus, but the diploid number of 52 chromosomes is quite common, although the karyotypic variability is extensive.

Bryconamericus exodon Eigenmann 1907

open access: yes, 2011
Bryconamericus exodon (Fig. 6 A-L) In the spermatozoon of Bryconamericus exodon the ovoid nucleus measures 1.5 µ m in the longitudinal axis and 1.2 µ m in the transverse axis. The surrounding strip of cytoplasm has no organelles (Fig. 6A). Nuclear rotation toward the flagellar axis was about 80 degrees (Fig. 6 A-B).

Trophic plasticity of omnivorous fishes in natural and human‐dominated landscapes

open access: yesLimnology and Oceanography, Volume 69, Issue 1, Page 189-202, January 2024.
Abstract The persistence of diverse communities and functioning ecosystems under increasing anthropogenic pressure relies on food web rewiring and the ability of animals to expand or change their diet in disturbed ecosystems. We combined a suite of diet tracing techniques to study trophic plasticity in omnivorous fishes, ecomorphologically similar ...
