Carotenoid-based coloration in cichlid fishes

open access: yesComparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2014
Animal colors play important roles in communication, ecological interactions and speciation. Carotenoid pigments are responsible for many yellow, orange and red hues in animals. Whereas extensive knowledge on the proximate mechanisms underlying carotenoid coloration in birds has led to testable hypotheses on avian color evolution and signaling, much ...

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

open access: yesFrontiers 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 ...

Population Genetics and Gene Flow in Cyphotilapia frontosa and Cyphotilapia gibberosa Along the East Coast of Lake Tanganyika

open access: yesFishes
The radiation of cichlid species in the East African Great Lakes is remarkable and rapid. The population genetics of two deep-water Cyphotilapia species along the east coast of Lake Tanganyika from Burundi to southern Tanzania was determined using ddRAD ...

Chickens First\ud \ud Speciation by “Hopeful Monsters” in Fraternal Supertwins\ud [PDF]

open access: yes, 2008
The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel how similar individual in the opposite sex to appear ...

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 ...

Rapid adaptive evolution of colour vision in the threespine stickleback radiation. [PDF]

open access: yes, 2016
Vision is a sensory modality of fundamental importance for many animals, aiding in foraging, detection of predators and mate choice. Adaptation to local ambient light conditions is thought to be commonplace, and a match between spectral sensitivity and ...

Actin-dependent cell elongation in teleost retinal rods: requirement for actin filament assembly. [PDF]

open access: yes, 1981
Teleost retinal rods elongate when exposed to light. Elongation is mediated by a narrow necklike region called the myoid. In the cichlid Sarotherodon mossambicus, the rod inner segment (composed of the myoid with adjacent ellipsoid) increases in length ...
