New study reveals rapidly adaptive radiation sources for loupes in Lake Mweru, East Africa: cnbeta.com
According to a new study published Wednesday in the journal Nature Communications, scientists analyzed more than 2,000 species of fish from two freshwater lakes in East Africa, as well as DNA analysis of more than 400 species of cipheridae (for example, tilapia belong to the family Cichlidae). Among them, the researchers found more than 40 new species in Lake Mweru. Hybrid offspring can feed on what their parents can't eat, invade new habitats, and swim deeper into the water than their ancestors.
Lead study author Joana Meier said in a statement: "When Lake Mweru was formed, it combined the pedidigrees of the cichlid family from the Congo and Zambezi rivers. The cichlids from these different water systems then mate with each other. This may be because when the lake forms, the water is very turbid and they don't see the right color, so the females are not so picky when choosing a mate in the new environment. Mating between different water systems of cichlids produces offspring that combine the genetic characteristics of both parent species very easily. ”
Meier said it's unclear whether new species can survive for long, as they could compete with each other and die. However, research conducted in Lake Mweru shows that in a new environment, where there are many ecological opportunities, hybridization may be a good thing and can actually increase biodiversity.
