A functional trade-off between trophic adaptation and parental care predicts sexual dimorphism in cichlid fish [PDF]

open access: yes, 2019
Although sexual dimorphism is widespread in nature, its evolutionary causes often remain elusive. Here we report a case where a sex-specific conflicting functional demand related to parental care, but not to sexual selection, explains sexual dimorphism ...

Phylogenomics uncovers early hybridization and adaptive loci shaping the radiation of Lake Tanganyika cichlid fishes

open access: yesNature 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 root of the East African cichlid radiations

open access: yesBMC Evolutionary Biology, 2009
Background For decades cichlid fishes (Perciformes: Cichlidae) of the East African cichlid radiations (Teleostei: Cichlidae) have served as natural experimental subjects for the study of speciation processes and the search for potential speciation key ...

Cichlid Size vs Flow Rate [PDF]

open access: yes, 2019
Cichlids are a diverse group of fish that are known for their prenatal and postnatal care of their eggs and frys (baby fish). This unique characteristic creates a limitation on the amount of eggs a cichlid can lay and protect, which is particulalry ...

Development of Primary Cell Cultures from Haplochromine Cichlid Bone-Derived Tissues

open access: yesFishes
Bone is a dynamic tissue with ecological and evolutionary importance, as it can grow and remodel itself in response to mechanical stimuli. In mammals, osteocytes are widely recognised as the central regulators of bone formation and mechanotransduction ...

Trophic Niche Differentiation and Mercury Levels in Cyphotilapia frontosa and C. gibberosa Along the East Coast of Lake Tanganyika

open access: yesFishes
Diet, trophic niche, and mercury were examined for Cyphotilapia frontosa and C. gibberosa along the east coast of Lake Tanganyika, from northern Burundi to the southern region near the Zambian border. Mercury levels were generally low across populations,
