Dr. Georgios Valsamakis, congratulations to receiving your PhD!

Still online, Georgios did a great job in defending his thesis. His talk and defence was even a summa cum laude (!), and in total he got a cum laude! All three female supervisors are super proud of him 🙂 And now up to a nice and successful postdoc time!


New publication by Afentoulis et al. in Front Ecol Evol


New Publication New Phytologist Griese, Caarls et al.


New publication by Valsamakis et al. in Front Plant Sci

Priming by timing: the longer Pieris brassicae eggs are exposed to A. thaliana plants the stronger the plants’ response and the more the hatching larvae suffer from it. This work has largely been conducted by Georgios Valsamakis, Vivien Lortzing and Norbert Bittner in the group of Monika Hilker.


New PhD students working on hitch-hiking Trichogramma wasps

Liana and Xianhui (from left) both just started their PhD on the ecology, evolution and genetics of anti-sex pheromones of passion-vine/cabbage white butterflies and natural selection by hitch-hiking egg parasitoids spying on these pheromones. Both will have supervisors from Biosystematics group and the Laboratory of Genetics @WUR. They will conduct field work either in Panama or The Netherlands, olfactometer bioassays, analyse pheromones and the genetics behind them.


New PhD student Eva Drukker

Eva Drukker (MSc) is from the Netherlands and studied biology at Wageningen University. She did her internship research at the Bureau Stadsnatuur, studying arthropods on green roofs. In March, just before the Corona outbreak, she started her PhD on this topic supervised by Prof. Eric Schranz, Casper Quist and me. For the coming four years she will be studying these new ecosystems in our urban landscape. Among other things she is trying to unravel the complicated interactions that take place in these elevated habitats. Besides her research, she is very fond of and experienced in teaching and therefore takes part in two courses that we give at Biosystematics Group.

New publications 2020


7th Vidi user committee meeting – on Skype

On April 20th we had our 7th meeting but our first online – due to the covid-19 outbreak. It went relatively smoothly and almost all members were present. We made quite some progress the last couple of months especially in Niccolo’s project on the genetics. Now that Lotte is back from maternity leave her project on the elicitor is getting back on track again!
