The opsin genes of amazonian cichlids
Molecular Ecology, 2017 Vision is a critical sense for organismal survival with visual sensitivities strongly shaped by the environment. Some freshwater fishes with a Gondwanan origin are distributed in both South American rivers including the Amazon and African rivers and ...

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

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 ...

Nature Communications, 2019 Recent studies have suggested that hybridization can facilitate adaptive radiations. Here, the authors show that opportunity for hybridization differentiates Lake Mweru, where cichlids radiated, and Lake Bangweulu, where cichlids did not radiate despite ...

Developmental basis of phenotypic integration in two Lake Malawi cichlids
EvoDevo, 2016 BackgroundCichlid fishes from the Rift Lakes of East Africa have undergone the most spectacular adaptive radiations in vertebrate history. Eco-morphological adaptations in lakes Victoria, Malawi and Tanganyika have resulted in a vast array of skull ...

Behavior of Rio Sao Francisco Piranhas in Response to Changes in Space and Density
Zoo Biology, EarlyView.ABSTRACT Previous observations of Rio Sao Francisco piranhas (Pygocentrus piraya) at Cleveland Metroparks Zoo revealed frequent aggressive interactions, which were associated with the injury and death of some individuals. Fishes are known to increase aggressive behavior when available space is limited.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal coloration serves a variety of visually related functions in nature (e.g. mate choice, aposematism and camouflage) but the pigments in integumentary tissues such as skin, scales and feathers may also serve functions unrelated to the visual environment (e.g ...
