Workshop 2     29 October 2021, Friday   Analysis and visualization of interaction datasets

Leader: Jorrit Poelen
Building on your existing or newly acquired experience with interaction data (e.g. Workshop 1), this event will familiarize you with main principles of analysis and visualization of interaction data. Pre-workshop reading required

09:00 – 10:00 Talya Hackett Introduction to network ecology
10:00 – 10:30 Q&As and discussion

14:30 – 17:00 Workshop 


The intensive three-day symposium program is comprised by keynote and contributed lectures by established dead wood researchers, and student presentations. In addition, satellite workshop on managing interaction data are arranged. The target group is advanced master and PhD students, but anyone with research interest and experience in dead wood ecology is welcome. The symposium is not suitable for absolute beginners in dead wood research, but use books recommended below to build or update your knowledge before joining the event. The goal of this symposium is to create an environment for communication among dead wood scholars and to close the gap between the university lectures and the real-life of a researcher and a conservationist, as well as promote connections across disciplines. We will go through a broad range of topics, such as biodiversity in dead wood in boreal and temperate environments, biodiversity conservation and restoration, and of course all kinds of lignicolous organisms: fungi, insects, and more. Мертвая древесина живее всех живых!

Assignment and study credits

No ECTS credits are provided for attendance only, and attendance certificates are only provided upon request; however, students giving a presentation will earn 1 ECTS and active participation in workshop and carrying out all workshop tasks will bring 1 ECTS per workshop (graded pass / fail).
