East African cichlid lineages (Teleostei: Cichlidae) might be older than their ancient host lakes: new divergence estimates for the east African cichlid radiation

BMC Evolutionary Biology, 2019
Background Cichlids are a prime model system in evolutionary research and several of the most prominent examples of adaptive radiations are found in the East African Lakes Tanganyika, Malawi and Victoria, all part of the East African cichlid 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

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.

Phylogeography and Ecological Niche Shape the Cichlid Fish Gut Microbiota in Central American and African Lakes

Frontiers in Microbiology, 2019
Cichlid fishes, with their repeated colonization of lakes and subsequent radiations at different scales of phylogenetic and ecological diversification, offer an excellent model system to understand the factors shaping the host-gut microbiota association ...

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).

Genetic Relatedness Promotes Equal Contributions of Males and Females to Brood Care in a Biparental Cichlid Fish. [PDF]

Ecol Evol
Here, we compared the individual contributions of males and females to brood care of kin and nonkin pairs in Pelvicachromis taeniatus, a biparental cichlid fish with pronounced kin‐mating preference. We found that in unrelated pairs, females cared more than males, whereas the sexes contributed equally in related pairs suggesting higher cooperation ...

An intronic transposon insertion associates with a trans-species color polymorphism in Midas cichlid fishes

Nature Communications, 2022
Polymorphisms have fascinated biologists for a long time, but their genetic underpinnings often remain elusive. Here, we aim to uncover the genetic basis of the gold/dark polymorphism that is eponymous of Midas cichlid fish (Amphilophus spp.) adaptive ...

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.
