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 ...

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

Frontiers 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 ...

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

Nature 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 ...

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

Fishes
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

Fishes
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,

Environmental enrichment and its effects on social dominance and welfare in a cichlid fish

Animal Welfare
Environmental enrichment can have complex, contradictory effects on aggression and animal welfare. Although increasing enrichment may reduce aggression by limiting the visibility of competitors, it may also intensify territorial defence and harm the ...

Comparison of gastropod mollusc (Apogastropoda: Hydrobiidae) habitats in two crater lakes in Nicaragua

Revista de Biología Tropical, 2008
The aquatic gastropod mollusc, Pyrgophorus coronatus, may perform an important role in the transmission of an emergent ocular pathology among fishes in Lake Apoyo, Nicaragua.

Los cromosomas mitóticos y meióticos del pez tropical Petenia splendida (Cichlidae)

Revista de Biología Tropical, 2008
Para describir los cromosomas del cariotipo en mitosis y meiosis de la mojarra tenguayaca P. splendida, se procesaron 60 larvas y doce jóvenes (seis hembras y seis machos) procedentes de Tabasco, México.

Maylandia (Teleostei: Cichlidae) Remains a Nomen Nudum

Taxonomy
The debate of the validity of Maylandia vs. Metriaclima as a genus for a group of rock-dwelling cichlids (Pseudotropheus zebra complex) in Lake Malawi, Africa, has been argued for more than 25 years.
