Supernumerary chromosome system, C-banding pattern characterization and multiple nucleolus organizer regions in Moenkhausia sanctaefilomenae (Pisces, Characidae)

Genetica, 1989
Chromosomes of Moenkhausia sanctaefilomenae (10 males and 20 females) collected from a tributary of the Tiete River (Botucatu, S.P. Brazil) were examined using kidney and testicular cells. Both males and females presented 2n=50 chromosomes and 1 to 8 small supernumerary microchromosomes.

New occurrence of microchromosomes B in Moenkhausia sanctaefilomenae (Pisces, Characidae) from the Paraná River of Brazil: analysis of the synaptonemal complex

Genetica, 2000
The Moenkhausia sanctaefilomenae specimens showed a karyotype consisting of 2n = 50 chromosomes with 12 metacentrics, 36 submetacentrics and two subtelocentrics. In addition to the basic karyotype, all the males specimens have cells ranging from zero to two B microchromosomes in mitotic metaphases.

Early ontogeny of aquarium-raised Moenkhausia sanctaefilomenae (Characiformes: Characidae)

Ichthyological Research, 2011
The ontogeny of the characiform fish Moenkhausia sanctaefilomenae, from early embryogenesis through the early larval period, is presented. Fertilized eggs were slightly elliptical, measured 0.6 mm in diameter, and were surrounded by a fertilization envelope 0.8 mm in diameter.

Cranial skeletogenesis and osteology of the redeye tetra Moenkhausia sanctaefilomenae

Journal of Fish Biology, 2012
The skeletogenesis and osteology of the syncranium of the redeye tetra Moenkhausia sanctaefilomenae is described. Skeletal development is rapid, with many elements of the chondrocranium and splanchnocranium well formed prior to the onset of ossification.

Effects of structural heterogeneity provided by the floating macrophyte Eichhornia azurea on the predation efficiency and habitat use of the small Neotropical fish Moenkhausia sanctaefilomenae

Hydrobiologia, 2009
Macrophytes have a fundamental structuring role in aquatic environments. Several authors have suggested that trophic interactions are particularly mediated by aquatic plants. In the current article, we evaluated the effects of the structural heterogeneity provided by Eichhornia azurea (Kunth) roots on predation and habitat use by the small fish ...

Predation Effect ofBelostoma dentatum(Hemiptera: Belostomatidae) on the Predator Perception and Behavioral Response ofMoenkhausia sanctaefilomenae(Pisces: Characidae)¹

Journal of Entomological Science, 2018
Abstract  Predation is an important interaction for the regulation of population dynamics due to the effect caused by the direct consumption of prey. However, some populations present strategies to detect risk of predation and react to the predator. Our objective was to evaluate the effect of the predation risk of Belostoma dentatum (Mayr), under the ...
