Application of the physical habitat simulation for fish species to assess environmental flows in an Atlantic Forest Stream in South-eastern Brazil

Neotropical Ichthyology
The physical habitat simulation sub-routine of the Instream Flow Incremental Methodology (IFIM) uses hydraulic modeling and suitability indices of target fish species to predict how differences in-stream flows affect the microhabitat occupation by fish ...

Extensive NOR Variability in Fishes of the Genus Bryconamericus (Characidae).

CYTOLOGIA, 1999
An extensive NOR variability was described in four Bryconamericus species which are still awaiting more precise taxonomic identification. Nine NOR phenotypes were identified by silver nitrate and mithramycin staining, and cytotaxonomy and phylogenetic relationships were inferred.
