In periode 6 (May-June) the Biodiversity of the Netherlands course started with 240 first-year Biology and Forest and Nature Conservation students. Assistant professor Sabrina Simon and me together with PhD student Thijmen Breeschoten and 7 student assistants teach the Fauna part on arthropod systematics and diversity. We visit 5 locations/habitats in the surroundings of Wageningen were students evaluate arthropod abundances. Many enthusiastic students with nets catching insects are all over the place!
