Guðbrandsson, Jóhannes; Kapralova, Kalina; Franzdottir, Sigridur Rut; Bergsveinsdóttir, Þóra Margrét; Hafstað, Völundur; Jónsson, Zophonías Oddur; Snorrason, Sigurður S.; Palsson, Arnar (Wiley, 2019-09-12)

The availability of diverse ecological niches can promote adaptation of trophic specializations and related traits, as has been repeatedly observed in evolutionary radiations of freshwater fish. The role of genetics, environment, and history in ...
Gene expression during early development and genetic variation among recently evolved sympatric Arctic charr (Salvelinus alpinus) morphs in Lake Þingvallavatn, Iceland

Guðbrandsson, Jóhannes (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-04-26)

The four morphs of Arctic charr (Salvelinus alpinus) in Lake Þingvallavatn, Iceland, which differ in many phenotypic traits related to morphology, life history, and feeding ecology, are believed to have evolved locally within the lake after the retreat ...
