Diverse prey capture strategies in teleost larvae [PDF]

eLife
Animal behavior is adapted to the sensory environment in which it evolved, while also being constrained by physical limits, evolutionary history, and developmental trajectories. The hunting behavior of larval zebrafish (Danio rerio), a cyprinid native to

Computer simulations on the sympatric speciation modes for the Midas cichlid species complex [PDF]

, 2007
Cichlid fishes are one of the best model system for the study of evolution of the species. Inspired by them, in this paper we simulated the splitting of a single species into two separate ones via random mutations, with both populations living together ...

Phylogenomics uncovers early hybridization and adaptive loci shaping the radiation of Lake Tanganyika cichlid fishes

Nature Communications, 2018
Lake Tanganyika’s cichlid radiation is the main source of East African cichlid diversity. Irisarri et al. resolve its phylogenetic backbone using anchored phylogenomics and identify trans-lineage hybridization prior to major speciation bursts and ...

The genomic timeline of cichlid fish diversification across continents

Nature Communications, 2020
Cichlids are a model for adaptive radiation, but the timing of their diversification is debated. Here the authors assemble 14 cichlid genomes, introduce a Bayesian approach to account for fossil-assignment uncertainty, and present a dated phylogenomic ...

Pronounced expression of extracellular matrix proteoglycans regulated by Wnt pathway underlies the parallel evolution of lip hypertrophy in East African cichlids [PDF]

eLife
Cichlid fishes inhabiting the East African Great Lakes, Victoria, Malawi, and Tanganyika, are textbook examples of parallel evolution, as they have acquired similar traits independently in each of the three lakes during the process of adaptive radiation.

Dynamic co-evolution of transposable elements and the piRNA pathway in African cichlid fishes [PDF]

Genome Biology
Background East African cichlid fishes have diversified in an explosive fashion, but the (epi)genetic basis of the phenotypic diversity of these fishes remains largely unknown.

GROWTH OF Geophagus brasiliensis REARED AT DIFFERENT TEMPERATURES AND FEEDING REGIMES

Boletim do Instituto de Pesca, 2021
The aim of this study was to evaluate the growth performance of Geophagus brasiliensis rearedb under distinct temperatures (24.3 ± 0.9, 28.1 ± 1.0, and 31.7 ± 0.8°C) and feeding regimes (apparent satiety and a supply of 4% of the total biomass).

Salinized water as a strategy for increase stocking density in Heros severus larviculture, an Amazonian ornamental fish

Boletim do Instituto de Pesca, 2023
The aim of this study was to evaluate the effect of different salinized water (0, 3 and 6 g L-1) and stocking densities (10, 15 and 20 larvae L-1) in Heros severus larviculture.
