Cool results from our bachelor student
Nina Gudrun
She analyzed tooth length variation by morphs in three icelandic lakes.
Allometric relationship - size effect on tooth lengths - varied by morphs
Her BS paper will get integrated with data on bone shape to explore plasticity and divergence in functional traits
Good reviews on "Gene flow and habitat heterogeneity shape coexistence dynamics of Arctic charr morphs in connected lakes" at Molecular Ecology
Rejected but encouraged resubmission (which I hate, its plain metric-playing)
The main result being #GeneticStructure of four sympatric morphs in #thingvallavatn #Iceland

Shaped by volcanoic activity and underground rivers feeding it

Shaping the organism: Genetic and environmental influence on development during rapid evolution
Positive selection acts on genetic variation, which in context of the environment an organism develops and functions in, leads to adaptive changes in specific traits
