Project title and definition: Phylogeny and classification of subtribe
Acalypheae (Euphorbiaceae)

An international team is presently revising the large Euphorbiaceae family
for the Flora Malesiana and Flora of Thailand projects (over 100 genera,
comprising more than 1500 species). Subtribe Acalypheae comprises many
valuable species, not only economically important (Acalypha, ornamentals;
Ricinius, medicinal, castor oil), but also some good indicators of various
kinds and degrees of ecological disturbance (Macaranga, Mallotus). The
present classification is based on macromorphological characters, it
comprises many monotypic taxa with unknown affinities, and it conflicts
with the results of recent molecular studies. Therefore, a new and
phylogenetically based classification is greatly needed. The selected
candidate will revise a few small genera, create a data matrix based on
macromorphological characters and analyse this phylogenetically. The main
part of the four year project will be to sequence several genes of selected
species and to analyse the results phylogenetically, separately and in
conjunction with the macromorphological data. The project will be an
international team endeavour with cooperation from American, British,
German, Indonesian, Malaysian and Thai institutes. The project has to
result in a PhD thesis. A limited amount of teaching is also included in
the job description.

M.Sc. degree in biology or (bio-)pharmaceutical sciences with experience in
plant taxonomy and DNA sequencing techniques.
