Social deprivation affects cooperative predator inspection in a cichlid fish [PDF]
Royal Society Open Science, 2015 The social environment individuals are exposed to during ontogeny shapes social skills and social competence in group-living animals. Consequently, social deprivation has serious effects on behaviour and development in animals but little is known about ...

Foraging environment determines the genetic architecture and evolutionary potential of trophic morphology in cichlid fishes [PDF]
, 2016 Phenotypic plasticity allows organisms to change their phenotype in response to shifts in the environment. While a central topic in current discussions of evolutionary potential, a comprehensive understanding of the genetic underpinnings of plasticity is

Sensory Drive in Cichlid Speciation [PDF]
The American Naturalist, 2006 The role of selection in speciation is a central yet poorly understood problem in evolutionary biology. The rapid radiations of extremely colorful cichlid fish in African lakes have fueled the hypothesis that sexual selection can drive species divergence without geographical isolation.

The Midas cichlid species complex: incipient sympatric speciation in Nicaraguan cichlid fishes? [PDF]
Molecular Ecology, 2004 AbstractSympatric speciation is a contentious concept, although theoretical models as well as empirical evidence support its relevance in evolutionary biology. The Midas cichlid species complex (Amphilophus citrinellus,labiatus,zaliosus) from several crater lakes in Nicaragua fits several of the key characteristics of a sympatric speciation model.

Population Genetic Structure of Three Cichlids in Ilorin, North-Central Nigeria
The Iraqi Journal of Veterinary Medicine, 2022 Cichlids are among the economically important which serve as a source of food for people around the world. A deep understanding of the population structure and genetic diversity of cichlids are vital for initiation of conservation policies and

Recent research in the African Great Lakes: fisheries, biodiversity and cichlid evolution [PDF]
, 2003 The East African Great Lakes are now well known for (1) their fisheries, of vital importance for their rapidly rising riparian human populations, and (2) as biodiversity hotspots with spectacular endemic faunas, of which the flocks of cichlid fishes ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Helminthologia, 2020 We recorded the metazoan parasite communities in three endemic cichlids (Chiapaheros grammodes, Vieja breidohri and V. hartwegi) collected between November 2008 and July 2009 in the upper Grijalva River Basin (GRB), Chiapas, Mexico.
