Cryptobia iubilans in Cichlids

EDIS, 2014
After many years of diagnostics at the University of Florida and at other laboratories around the country, it appears that Cryptobia iubilans is not uncommon among cichlids, and that environmental and other factors determine the extent of disease.

Nonapeptide molecular evolution during the adaptive radiation of Tanganyika cichlids. [PDF]

J Neuroendocrinol
Abstract Oxytocin (OT) and vasotocin (VT) are evolutionarily conserved nonapeptides that regulate a wide range of physiological and behavioral processes in vertebrates. Their receptor families have undergone gene duplications that facilitated functional diversification throughout vertebrate evolution.

Possible Involvement of Ghost Introgressions in the Striking Diversity of Vomeronasal Type 1 Receptor Genes in East African Cichlids [PDF]

Ecology and Evolution
Cichlids that have undergone adaptive radiation are genetically close but exhibit extreme ecological and morphological diversity, making them useful for understanding speciation mechanisms.

Recent Polygenic Adaptation in Heavily Fished Malawi Cichlids. [PDF]

Mol Ecol
ABSTRACT Intense fishing pressure can drive rapid evolution in wild populations, yet the underlying genomic mechanisms often remain elusive. Here, we investigate the genomic consequences of five decades of intense harvesting on the cichlid fish Copadichromis mloto in Lake Malombe, Malawi.

Microcomputed tomography used to link head morphology and observed feeding behavior in cichlids of Lake Malaŵi

Ecology and Evolution, 2021
Cichlids inhabiting the Great Lakes of Africa have radiated extremely rapidly, with Lake Malaŵi harboring some 850 species. This rapid radiation may be linked to the diversity in behaviors, sexual selection, and phenotypic plasticity.

Lateralization of lateral displays in convict cichlids [PDF]

Biology Letters, 2011
We examine lateralization of lateral displays in convict cichlids, Amatitlania nigrofasciata , and show a population level preference for showing the right side. This enables contesting pairs of fish to align in a head-to-tail posture, facilitating other activities.

Dynamic co-evolution of transposable elements and the piRNA pathway in African cichlid fishes [PDF]

Genome Biology
Background East African cichlid fishes have diversified in an explosive fashion, but the (epi)genetic basis of the phenotypic diversity of these fishes remains largely unknown.

Distribution and abundance of cichlids in the New Calabar River, Nigeria

Journal of Fisheries, 2018
This study was conducted to study the distribution, abundance and diversity of the cichlids in the New Calabar River, Nigeria. A total of 1073 cichlids belonging to ten species and seven genera (Coptodon guineensis, C. zillii, C.

Disturbance cues in freshwater prey fishes: Does urea function as an ‘early warning cue’ in juvenile convict cichlids and rainbow trout?

Environmental Epigenetics, 2012
Freshwater vertebrate and invertebrate prey species commonly rely on chemosensory information, including non-injury released disturbance cues, to assess local predation threats.

Oca2 targeting using CRISPR/Cas9 in the Malawi cichlid Astatotilapia calliptera

Royal Society Open Science, 2022
Identifying genetic loci underlying trait variation provides insights into the mechanisms of diversification, but demonstrating causality and characterizing the role of genetic loci requires testing candidate gene function, often in non-model species ...
