The science of Ethnobotany deals with traditional plant use by people in the past, present and future. This course will deal with theoretical aspects, qualitative and quantitative research methods and excursions to tropical gardens and migrant markets. Students will learn how to document traditional knowledge, get acquaintanced with key concepts like cultural keystone species, doctrine of the signatures, traditional medicine and non-timber forest products. During excursions, they will practise with interviewing people on traditional plant use.
The course is taught by Professor Tinde van Andel, Naturalis chair in Ethnobotany at Biosystematics, Wageningen University.

Master project – 6 months (flexible) at IBED, UvA
This parasite is detrimental to monarchs, reducing survival, adult lifespan and flightability. Monarchs become infected with this parasite when ingesting infective spores as caterpillars. The parasite then grows inside the caterpillar and pupa to form millions of dormant
spores on adult butterflies, which are shed during oviposition to cause new infections. Previous work has shown that milkweeds, the host plants of monarch caterpillars, contain chemicals called cardenolides that reduce parasite infection. Other studies have also shown that infected females prefer to lay their eggs on milkweed with higher concentrations of cardenolides, which makes their offspring less sick. This project aims to determine whether the altered oviposition choice is due to different chemical perceptions of infected and uninfected monarchs.

Characterization of a candidate gene for pheromone differentiation in a moth
Moths possess a unique sexual communication system: females attract conspecific males by using species‐specific sex pheromones. Due to this fine‐tuning, the development of novel pheromone systems is an evolutionary mystery. This project will focus on the model insect
species to understand the evolution of sexual communication: the European Corn Borer, Ostrinia nubilalis which consists of two sex pheromone strains. The gene underlying pheromone variation in females was identified (Lassance et al. 2010). However, the gene underlying preference in the males is not identified yet. We conducted many genetic analyses and have identified a specific locus at the Z‐chromosome, which contains a highly interesting candidate gene that is involved in neurogenesis in other species. The aim of this project is to characterize this candidate gene, using in situ hybridizations and CRISPR/Cas9.
Technical skills/methods to learn:
1) in situ hybridization to localize the gene in the brain and/or the antennas, and to associate the gene with the olfactory receptors (ORs) that are involved in sex pheromone perception.
2) Functional characterization of the candidate gene, using targeted transgenesis with the CRISPR/Cas9 complex.
We are looking for a highly motivated student with BSc degree in biology and experience in molecular biology. Experience on insects’ manipulation and physiology are a plus. This project is a collaboration between the University of Amsterdam (Institute for Biodiversity and
Evolutionary Dynamics, IBED), Netherlands and the Institute for Agricultural Research (INRA) in Versailles, France. Therefore, communication skills in English (oral and written) are necessary and knowledge of French is a plus. There will be a monthly salary of 550 euros, for every complete month worked, for 6 months maximum. The salary is paid by the Institute of Ecology and Environnemental Sciences (iEES) ‐ Paris, France, with the obligation for the student to administratively subscribe to the iEES (no subscription fees).
