The Lake Victoria flock contains ten times less mtDNA variation than the Lake Malawi radiation, consistent with current estimates of the ages of the lakes. We present results of a phylogenetic ...

The macabre diets of scale-eating cichlids help shed light on the important role of frequency dependence in shaping genetic variation and the natural world. By Jeffrey McKinnon / MIT Press Reader ...

A frustration of evolutionary biologists is that genetics can account for only a small percent of variation in physical traits. Now researchers have found new results on how another factor, a behavior ...

Researchers at the Forsyth Institute have discovered that the genes that influence the jaws of cichlid fish, tropical freshwater fish renowned for head shape diversity, offer insight into overall ...

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 ...

A new study that looked at gut length variation between cichlid fish species found that some of the genetic loci for the trait are sex-specific even though males and females of the same species have ...

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 ...
