Just published 'Dietary Differentiation Between Sympatric #Ecotypes of #Astatotilapia calliptera From Lake Masoko, #Tanzania Revealed by Metabarcoding'! https://bit.ly/3GTRKjI Great to be part of this work led by Dr Kirthana Pillay (FSBI PhD). Nostalgic, given that my MSci thesis looked at the population genetics in these #cichlids in "Darwin's puddle"! Diet of the benthic and littoral ecomorphs differ, indicating resource partitioning, implicating trophic divergence with sympatric #speciation.

Genetic mutation prompts 'deadbeat dad' fish to start raising their offspring

University of Maryland researcher Cheng-Yu Li was in the lab one day when he noticed a fish with a protruding jaw: A telltale sign that it was incubating eggs in its mouth, keeping its offspring safe until they were big enough to swim solo.
