Evolutionary divergence in life history traits among populations of the Lake Malawi cichlid fish Astatotilapia calliptera
During the early stages of adaptive radiation, populations diverge in life history traits such as egg size and growth rates, in addition to eco-morphological and behavioral characteristics. However, there are few studies of life history divergence within ongoing adaptive radiations. Here, we studied Astatotilapia calliptera, a maternal mouthbrooding cichlid fish within the Lake Malawi haplochro...
متن کاملEvolution of a cichlid fish in a Lake Malawi satellite lake.
Allopatric divergence in peripheral habitats may lead to rapid evolution of populations with novel phenotypes. In this study we provide the first evidence that isolation in peripheral habitats may have played a critical role in generation of Lake Malawi's cichlid fish diversity. We show that Lake Chilingali, a satellite lake 11.5 km from the shore of Lake Malawi, contains a breeding population ...
متن کاملA role for male bower size as an intrasexual signal in a Lake Malawi cichlid fish
Disruptive sexual selection through female mate choice has been proposed as a key mechanism driving the evolution of haplochromine cichlid fish diversity. Here we investigated if male secondary sexual traits employed by females in direct mate choice have an additional function in male competition. We conducted a field experiment on aggression among males of a lekking Lake Malawi cichlid species...

متن کاملSegregation of Species-Specific Male Attractiveness in F2 Hybrid Lake Malawi Cichlid Fish
Among the huge radiations of haplochromine cichlid fish in Lakes Malawi and Victoria, closely related species are often reproductively isolated via female mate choice although viable fertile hybrids can be produced when females are confined only with heterospecific males. We generated F(2) hybrid males from a cross between a pair of closely related sympatric cichlid fish from Lake Malawi. Labor...
