    • Good-bye to tropical alpine plant giants under warmer climates? Loss of range and genetic diversity in Lobelia rhynchopetalum 

      Gelete, Desalegn Chala; Brochmann, Christian; Psomas, Achilleas; Ehrich, Dorothee; Gizaw, Abel; Masao, Catherine; Bakkestuen, Vegar; Zimmermann, Niklaus E (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11-25)
      The main aim of this paper is to address consequences of climate warming on loss of habitat and genetic diversity in the enigmatic tropical alpine giant rosette plants using the Ethiopian endemic Lobelia rhynchopetalum as a model. We modeled the habitat suitability of L. rhynchopetalum and assessed how its range is affected under two climate models and four emission scenarios. We used three ...

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

      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 ...
