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.

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

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.

Determination of Artificial Incubation Time of Some Malawi Cichlid Species Incubating in the Mouth (Iodotropheus sprengerae, Cyrtocara moorii, Maylandia estherae, Labidochromis caeruleus) Eggs

Acta Natura et Scientia, 2020
Malawi cichlid species belonging to the Cichlidae family are among the most popular commercial species in the aquarium industry. Females of this species begin to incubate their eggs in the mouth after ovulation. Professional producers continue to induce

Freshwater hydrozoan blooms alter activity and behaviour of territorial cichlids in Lake Tanganyika [PDF]

Royal Society Open Science, 2019
Blooms of gelatinous zooplankton can represent dramatic environmental perturbations for aquatic ecosystems. Yet, we still know little about how blooms impact fitness-related behaviours of fish caught within their areas of effect, especially for ...

The evolution of monogamy in cichlids and marine reef fishes

Frontiers in Ecology and Evolution, 2022
Although several hypotheses have been proposed to explain the emergence of social monogamy, its origin is still intensely debated. Monogamy has many potential drivers, but evolutionary causality among them remains unclear.
