Evolution of colour patterns in East African cichlid
And even when one eschews these standard textbooks, studies that first come to mind when one thinks of influential tropical evolutionary biology are, for example, the work on African cichlids
Washington, Nov 25 (ANI): While experimenting with African cichlid
fish, Stanford biologists discovered that when a female shows a preference for a particular male, but then witnesses him losing a fight with another male, her feelings toward him change.
Sebastian Baldauf from the University of Bonn, Germany, worked with a team of researchers to study the effects of female ornamentation in the African cichlid
fish Pelvicachromis taeniatus.
Ribbink examines biodiversity and speciation in African cichlid
fishes, and finds unexpected differences between lake and riverine faunas.
Desjardins and coauthor Russell Fernald, professor of biology, arrived at their conclusion by comparing the behavior and brain activity of male African cichlid
fish during and after one-on-one encounters with either a mirror or other another male of about the same size.
Lake Tanganyika as an evolutionary reservoir of old lineages of East African cichlid
fishes: inferences from allozyme data.
The East African cichlid
fishes that inhabit Lakes Malawi, Tanganyika, and Victoria are known for their sexually distinct appearance.
The research on African cichlids
was inspired by anecdotal reports of their intelligence from aquarium owners.
According to the Canadian scientists, who studied African Cichlids
, a popular aquarium species, fish demonstrate several complex behaviours, including aggression, causing the scientists to predict that they could be capable of advanced memory tasks.
Comparing the results with published data from African cichlids
, that the genes differentially expressed in pharyngeal jaw plastic response are the same in both closely and distantly related cichlid lineages (thus suggesting a conserved molecular basis for pharyngeal jaw plasticity).
