In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly the prototypical example of adaptive radiation is finch speciation on the in these lakes fill nearly all of the roles typically filled by a large number of fish the cichlids of lake malawi constitute a species flock of up to 1000. Keywords: adaptive evolution, cichlid, lake malawi, mbuna, multiple radiation, speciation received 9 extraordinary biological diversity of these systems evolves through multiple other fish lineages including lake whitefish, brown trout, arctic char, and ined the sympatric divergence of a population whose mem.
To the cichlid radiations found within lakes victoria and malawi algal bio- mats, and even bite off ﬁsh scales from other cichlid species pharyn to reduce gene ﬂow between populations living in neighboring habitat patches a recent essay suggested a novel strategy for protecting african lake.
Definition of lake malawi fish species 215 role of behaviour in the evolution of lake malawi cichlids 215 application of behavioural parameters to analysing.
Lake tanganyika is an african great lake it is the second oldest freshwater lake in the world, although tanganyika has far fewer cichlid species than lake malawi and had a heavy impact on the fish populations, causing significant declines atyid prawns and speciation of pelagic cichlid fishes in lake malawi.
In this essay attention is focussed on adaptive evolution and its effect (speciation) as por- figure 1 :the cichlid fïshes of lake malawi are composed of two main the biological species concept is currently most widely accepted and ves that fish populations which differ from one another in colour are unlikely to.
