To investigate forces influencing diversification in Neotropical fishes, the phylogenetic relationships among species and populations of the cichlid genus Cichla were examined. Mitochondrial DNA was sequenced for 454 individuals of the 5 nominal Cichla species and several putative undescribed species.

Journal of Fish Biology, 2020
AbstractThe reproductive strategy of the non‐native predator cichlid Cichla kelberi was determined to explain its success after more than 60 years of being introduced into an isolated reservoir in southeastern Brazil. This was one of the first‐known translocations of the genus Cichla out of its natural range.

Aquatic Conservation: Marine and Freshwater Ecosystems, 2022
Abstract Peacock basses (Cichla spp.) have been introduced in impoundments for decades, and their negative impacts on the native fish fauna have been documented. However, previous studies largely focused on the overall responses of fish assemblages, often neglecting specific predator–prey interactions and the underlying effects of environmental ...

Biological Invasions, 2010
Prey naivete is proposed as one of the main reasons behind species extinctions attributed to invasive predators. This study examined whether the naivete hypothesis could explain extinctions after the introduction of peacock bass (Cichla kelberi) in Parana River, Brazil.

Neotropical freshwater ecosystems are experiencing a great expansion in the number of invasive species, which is especially alarming since this region harbours 30% of the world’s fish biodiversity with high levels of endemism. We aimed to evaluate the main predictors of peacock basses (Cichla spp.) abundance outside their native range, which are the ...

Molecular Phylogenetics and Evolution, 2013
The inference of phylogenies of closely related species is obstructed by phenomena such as porous species boundaries and deep coalescence, and is often exacerbated by low levels of nucleotide variation among most loci surveyed in phylogenetic studies.

Conservation Genetics, 2015
The Neotropics harbor the world’s most diverse freshwater fish fauna, with many of these species supporting major commercial, subsistence, or sport fisheries. Knowledge of population genetic structure is available for very few Neotropical fishes, thereby restricting management.

AbstractIntroduction of peacock cichlids Cichla spp. into tropical and subtropical systems where they can successfully overwinter and reproduce has been a common practice in fisheries management. We evaluated the compatibility of nonnative butterfly peacock cichlids Cichla ocellaris and largemouth bass Micropterus salmoides in Puerto Rico reservoirs ...

AbstractNonlethal techniques for sampling the stomach contents of fishes have been developed for a variety of fish species. The goal of this study was to determine whether pulsed gastric lavage or acrylic stomach tubes were more effective for extracting stomach contents from Butterfly Peacock Bass Cichla ocellaris, specifically which was least ...
