Macroecology of metazoan parasite communities of Cichla kelberi and C. piquiti (Osteichthyes, Cichlidae).

open access: yes, 2012
The macroecology search geographical patterns of distribution and abundance of a species in large-scale, and represents one of the central themes of biogeography. The parasites communities have a fundamental role in the models for studies of biodiversity

Molecular and morphological approaches for species delimitation and hybridization investigations of two Cichla species

open access: yes, 2017
The hybridization is a widely-discussed issue in several studies with fish species. For some authors, hybridization may be related with diversification and speciation of several groups, or also with the extinction of populations or species.

Loss of biodiversity in a conservation unit of the Brazilian Atlantic Forest: the effect of introducing non-native fish species

open access: yesBrazilian Journal of Biology
The introduction of species has become an important problem for biodiversity and natural ecosystem conservation. The lake system of the middle Rio Doce (MG, Brazil) comprises c. 200 lakes at various conservation states, of which 50 are located within the
