Cichlids are one of the largest and strangest groups of vertebrate fish — fish with backbones — on Earth. They’re popular as pets and farmed in aquaculture, and scientists have been studying them ...

In 2018 and 2020, Michael Pauers traveled 8,500 miles to go fishing in Lake Malawi, but not with a pole and lure. He and his research colleague, Titus Phiri, were collecting and describing ...

Animals are remarkably diverse in their sleep and activity patterns due to foraging strategies, social behavior and their desire to avoid predators. With more than 3,000 types of cichlids, these ...

The Nicaraguan lakes represent an ideal continent-island-like setting to study the colonization patterns of both fish and their parasites. The dominant fish fauna are cichlids, particularly the Midas ...

The biological family Cichlidaea is one of the most fascinating examples of animal evolution on Earth. Convict cichlids are a widespread, well-known species within this unique group. Convict cichlids ...

The cichlids of Lake Tanganyika in Africa are highly diverse -- including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, ...

The cichlid fishes of Lake Malawi are famously diverse. However, phylogenetic and population genetic studies of their history have been difficult because of the great amount of genetic variation that ...

Regulatory changes are major drivers of adaptive diversification 1. The genomic mechanisms determining levels of gene expression are likely critical to adaptive phenotypic innovations, but we are only ...

Africa’s deepest freshwater lake holds a dizzying array of animals, including hundreds of species of cichlid fish found nowhere else in the world. They crowd the waters of Lake Tanganyika, with scales ...

It all started with the Convict cichlids. The small striped fish, native of Central America, captured Sac State Biology Professor Ron Coleman’s attention in a laboratory at the University of Toronto ...

Animals are remarkably diverse in their sleep and activity patterns due to foraging strategies, social behavior and their desire to avoid predators. With more than 3,000 types of cichlids, these ...

Despite the dramatic difference between day and nightlife, how fish exploit different times of day has not been studied systematically. Scientists explored alterations in the circadian timing of ...
