Proficiat Dr Bas Kokshoorn

It’s not an everyday occasion to report on, a
malacological thesis. Today Bas Kokshoorn defended
his Ph.D. thesis at the University of Leiden.
The thesis consists of eight chapters of which several will be published later in peer-reviewed journals. I mentioned already the chapter on prime and remnant species. Other chapters deal with an introduction to the family Chondrinidae, the historical biogeography of the genus Chondrina, a phylogenetic analysis of the Abida secale-complex and its ecophenotypic variation and finally a taxonomic revision of the Chondrinidae.
In the discussion I found the part on the altitudinal gradients and shell morphology particularly interesting. To what extent is selection expressed when comparing samples collected on different mountain transects? Also the factors explaining the variation were discussed. The methodology applied may be applicable to some questions I have about some Peruvian species, e.g. here. Other parts of Bas’ thesis will surely also be inspirational during future work.
More information can be found here (at the time of writing offline, but check as he promises to be back a.s.a.p.). Anyhow, proficiat Dr Bas!
