Open AccessExpression variations in ectodysplasin-A gene (eda) may contribute to morphological divergence of scales in haplochromine cichlids
Elasmoid scales are one of the most common dermal appendages and can be found in almost all species of bony fish differing greatly in their shape. Whilst the genetic underpinnings behind elasmoid scale develop...

Open AccessGene coexpression networks reveal molecular interactions underlying cichlid jaw modularity
The oral and pharyngeal jaw of cichlid fishes are a classic example of evolutionary modularity as their functional decoupling boosted trophic diversification and contributed to the success of cichlid adaptive ...

Open AccessDivergence in larval jaw gene expression reflects differential trophic adaptation in haplochromine cichlids prior to foraging
Understanding how variation in gene expression contributes to morphological diversity is a major goal in evolutionary biology. Cichlid fishes from the East African Great lakes exhibit striking diversity in tro...

Open AccessPopulation dynamics with a mixed type of sexual and asexual reproduction in a fluctuating environment
Carassius gibelio, a cyprinid fish from Eurasia, has the ability to reproduce both sexually and asexually. This fish is also known as an invasive species which colonized almost all continental Europe, most likely...

Open AccessAncestral state reconstruction reveals multiple independent evolution of diagnostic morphological characters in the "Higher Oribatida" (Acari), conflicting with current classification schemes
The use of molecular genetic data in phylogenetic systematics has revolutionized this field of research in that several taxonomic grou**s defined by traditional taxonomic approaches have been rejected by mol...

Open AccessNuclear and mitochondrial data reveal different evolutionary processes in the Lake Tanganyika cichlid genus Tropheus
Cichlid fishes are notorious for their wealth of intra- and interspecific colour pattern diversity. In Lake Tanganyika, the endemic genus Tropheus represents the most impressive example for geographic variation i...

Open AccessReticulate phylogeny of gastropod-shell-breeding cichlids from Lake Tanganyika – the result of repeated introgressive hybridization
The tribe Lamprologini is the major substrate breeding lineage of Lake Tanganyika's cichlid species flock. Among several different life history strategies found in lamprologines, the adaptation to live and bre...

Open AccessMitochondrial phylogeny and phylogeography of East African squeaker catfishes (Siluriformes: Synodontis)
Squeaker catfishes (Pisces, Mochokidae, Synodontis) are widely distributed throughout Africa and inhabit a biogeographic range similar to that of the exceptionally diverse cichlid fishes, including the three East...
