TL;DR: In this paper, the authors study sequence evolution and gene expression of core genes of sexual development in a prime model system in evolutionary biology, the East African cichlid fishes.

TL;DR: Investigating the AR of cichlid fishes in East African Lake Tanganyika and using macroevolutionary model fitting to evaluate whether diversification happened in temporal stages suggests that trophic traits diversifying earlier than traits implicated in macrohabitat adaptation and that sexual communication traits diversify late in the radiation.

TL;DR: The collection and annotation of more than 12,000 expressed sequence tags (ESTs) generated from three different cDNA libraries obtained from the East African haplochromine cichlid species Astatotilapia burtoni and Metriaclima zebra found that four genes showed the signature of positive selection as revealed by calculating Ka/Ks ratios.

TL;DR: The findings suggest that plasticity in opsin gene expression of damselfish is highly species‐specific, possibly due to ecological differences in visual tasks or, alternatively, under phylogenetic constraints.

TL;DR: This work compares the genetic population structures and gene flow of seven ecologically distinct notothenioid species of the southern Scotia Arc based on nuclear microsatellites and mitochondrial DNA sequences and shows low-population differentiation and high gene flow for all investigated species independent of their adult life history strategies.
