Dr. Mark Mort studies the evolutionary relationships of the angiosperm family Crassulaceae using DNA sequences from chloroplast and nuclear gene regions.


Reconstructing the evolutionary relationships of the angiosperm family Crassulaceae using DNA sequences from chloroplast and nuclear gene regions. Examining the patterns of physiological and morphological evolution of Aeonium on the Canary Islands. This ongoing project is in collaboration with Drs. Javier Francisco-Ortega (Florida International University) and Arnoldo Santos-Guerra (Botanical Garden of Puerto de la Cruz, Tenerife, Canary Islands). Preliminary phylogenetic analyses of the South African members of Crassulaceae, focusing primarily on the evolution of the large, morphologically-diverse genus Crassula. This project will involve extensive fieldwork in South Africa in collaboration with Dr. Ernst van Jaarsveld (Kirstensbosch Botanical Garden), Gideon Smith and Priscilla Burgoyne of the Natioinal Botanical Institute of South Africa.

Research interests:

  • Angiosperm phylogenetics
  • Island evolution
  • Physiological evolution
  • Systematic methods
  • Crassulaceae
  • Asteraceae
  • Biogeography
