A whole-body micro-CT scan library that captures the skeletal diversity of Lake Malawi cichlid fishes

The paper presents a dataset of whole-body CT scans of Lake Malawi cichlid fishes, enabling morphological study and comparisons across species.

Ancient and ongoing hybridization in the Oreochromis cichlid fishes

This study examines ancient and contemporary hybridization in Oreochromis cichlids, revealing widespread ancient gene flow but limited adaptive radiation, and identifying modern hybridization threats to biodiversity and aquaculture.

A new species of Lethrinops (Cichliformes: Cichlidae) from a Lake Malawi satellite lake, believed to be extinct in the wild.

The paper describes a new cichlid species, Lethrinops chilingali, from Lake Chilingali, Malawi, and notes its likely extinction in the wild.

Ecological speciation promoted by divergent regulation of functional genes within African cichlid fishes

The paper investigates transcriptome divergence in African cichlid fishes, identifying regulatory variants contributing to ecological speciation through differential gene expression and splicing.

Differential use of multiple genetic sex determination systems in divergent ecomorphs of an African crater lake cichlid

The paper identifies three coexisting sex-determining alleles in two ecomorphs of Astatotilapia calliptera, showing genetic interactions affecting fitness and speciation.

Estuarine molecular bycatch as a landscape-wide biomonitoring tool

The paper shows that fish-targeted eDNA metabarcoding can detect birds and mammals, providing insights into spatial and temporal faunal variation in estuaries.

Newly discovered tilapia cichlid fish biodiversity threatened by hybridization with non-native species

The paper identifies hybridization threats to newly discovered tilapia populations and estimates their divergence time using genomic data.

Relative growth of invasive and indigenous tilapiine cichlid fishes in Tanzania

This study compares the relative growth rates of invasive Nile tilapia and indigenous Jipe tilapia in Tanzania, finding higher growth in the invasive species, which may indicate competitive advantage.

A survey of fishes of Hombolo Lake, Dodoma, Tanzania, with evidence for local extinction of a native tilapia as a consequence of stocking

The paper surveys fish species in Hombolo Lake, Tanzania, and finds evidence that a native tilapia species has gone locally extinct due to competition or genetic swamping from introduced species.

Whole genome sequences of Malawi cichlids reveal multiple radiations interconnected by gene flow

The study sequenced 73 Lake Malawi cichlid species to reveal evolutionary processes driving adaptive radiation and gene flow between lineages.

The genomic basis of adaptation to the deep water ‘twilight zone’ in Lake Malawi cichlid fishes

The paper investigates genomic adaptation to deep water environments in Lake Malawi cichlids, identifying candidate genes and supergene complexes associated with deep water survival.
