Morphological diversity of the genus Telmatochromis from the Lake Tanganyika drainage with the description of a new riverine species and the generic reassignment of the Malagarasi River lamprologine

Journal of Fish Biology, EarlyView.
Abstract The lamprologine cichlid genus Telmatochromis was long considered primarily lacustrine and endemic to Lake Tanganyika until an undescribed Telmatochromis species was reported from the Lufubu River (Lake Tanganyika drainage, Zambia). A phylogenomic study in 2021 confirmed the association of Telmatochromis sp.

Genetic and developmental origins of a unique foraging adaptation in a Lake Malawi cichlid genus

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Biologists have long been captivated by novel traits because they provide insights into both the origin of and constraints on morphological variation. The iconic adaptive radiations of cichlid fishes have led to incredible diversity of form,

Lungfish‐like antero‐labial tooth addition and amphibian‐like enameloid‐enamel transition in the coronoid of a Devonian stem actinopterygian

Journal of Anatomy, EarlyView.
The tooth patterning logic, which cannot be inferred from surface morphology, is revealed by visualizing buried tooth remnants in 3D. The primary teeth are added labially, initially organized in radial rows, which transition into linear rows where the coronoid becomes slender.

Pigments of a color polymorphism in a cichlid fish

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1973
Abstract 1. 1. Cichlasoma citrinellum occurs as gray or gold morphs in lakes in Nicaragua. The gold morph is variable and individuals range from yellow to dark orange. 2. 2. The pigments responsible for the carotenoid coloration are e-carotene and canthaxanthin. The gray morph contains a carotenoid component and also heavy melanin deposits.

Success of cuckoo catfish brood parasitism reflects coevolutionary history and individual experience of their cichlid hosts

Science Advances, 2018
Evolution teaches cichlids to outwit baby-killing cuckoo catfish. Obligate brood parasites manipulate other species into raising their offspring.

Hybridization and gene expression: Beyond differentially expressed genes

Molecular Ecology, EarlyView.
Abstract Gene expression has a key role in reproductive isolation, and studies of hybrid gene expression have identified mechanisms causing hybrid sterility. Here, we review the evidence for altered gene expression following hybridization and outline the mechanisms shown to contribute to altered gene expression in hybrids. Transgressive gene expression,

Convergence of gut microbiotas in the adaptive radiations of African cichlid fishes

The ISME Journal, 2017
Ecoevolutionary dynamics of the gut microbiota at the macroscale level, that is, in across-species comparisons, are largely driven by ecological variables and host genotype.

Neurogenomic landscape associated with status‐dependent cooperative behaviour

Molecular Ecology, EarlyView.
Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.

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

Fishes
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 ...
