Two 5S rDNA arrays in Neotropical fish species: is it a general rule for fishes ?
(Kluwer Academic Publ, 2001-01-01)
In this paper we describe Southern blot hybridization results probed with 5S rRNA genes for several Neotropical fish species representing different taxonomic groups. All the studied species showed a general trend with the ...
Neotropical fish-fruit interactions: eco-evolutionary dynamics and conservation
(Wiley-Blackwell, 2015-11-01)
Frugivorous fish play a prominent role in seed dispersal and reproductive dynamics of plant communities in riparian and floodplain habitats of tropical regions worldwide. In Neotropical wetlands, many plant species have ...

Synaptonemal complex analysis in the fish species Piaractus mesopotamicus and Colossoma macropomum, and in their interspecific hybrid
(2002-01-01)
The surface-spreading technique for visualization of whole cell synaptonemal complex (SC) complements was employed to study the chromosome synapsis in spermatocytes of P. mesopotamicus, C. macropomum and in their interspecific ...
