(PhysOrg.com) -- In African cichlid fish society, only the dominant male reproduces. But Stanford researchers have found that if the dominant male disappears, a subordinate cichlid can rise to the ...

Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its ...

Scientists, led by University of Bristol, have been studying a fish sensory organ to understand cues for collective behavior which could be employed on underwater robots. Why would having two sets of ...

Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve. In research ...

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 ...

Biologists have discovered that the cichlid fish can see in the near infrared range; this was thought to be unlikely until now. Seeing in the infrared range is apparently helping fish to hunt in ...

Beau Alward, University of Houston assistant professor of psychology, who holds a joint appointment in biology and biochemistry and is director of the Social Neuroscience Lab, has received the Beckman ...

African cichlid fishes represent one of the most striking examples of adaptive radiation, with hundreds of species evolving in the Great Lakes of East Africa and in neighbouring river systems.

Sex-determining systems may evolve rapidly and contribute to lineage diversification. In fact, recent work has suggested an integral role of sex chromosome evolution in models of speciation. We use ...
