    • Afro-alpine flagships revisited: Parallel adaptation, intermountain admixture and shallow genetic structuring in the giant senecios (Dendrosenecio) 

      Tusiime, Felly Mugizi; Gizaw, Abel; Gussarova, Galina; Nemomissa, Sileshi; Popp, Magnus; Masao, Catherine Aloyce; Wondimu, Tigist; Abdi, Ahmed Abdikhadir; Mirre, Virginia; Muwanika, Vincent; Eilu, Gerald; Brochmann, Christian; Kiflemichael, Tigist Wondimu (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-18)
      Distantly related lineages of the enigmatic giant rosette plants of tropical alpine environments provide classical examples of convergent adaptation. For the giant senecios (Dendrosenecio), the endemic landmarks of the East African sky islands, it has also been suggested that parallel adaptation has been important for within-lineage differentiation. To test this hypothesis and to address potential ...

    • Vicariance, dispersal, and hybridization in a naturally fragmented system: the afro-alpine endemics Carex monostachya and C. runssoroensis (Cyperaceae) 

      Gizaw, Abel; Kifilemichael, Tigist Wondimu; Tusiime, Felly Mugizi; Masao, Catherine; Abdi, Ahmed Abdikhadir; Popp, Magnus; Ehrich, Dorothee; Nemomissa, Sileshi; Brochmann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-08)
      The naturally fragmented habitat on the tallest African mountains provides a good model system to study vicariance, dispersal, and hybridization. Many mountains are separated by lowland that likely was unsuitable for high-alpine plants even during cold climatic periods. <br> We explore the relative importance of these processes using two endemic sister species: the widespread Ethiopian/eastern East ...
