Obituary: Prof. Olaf Weyl, IPBES expert
IPBES has learned with great sadness that Professor Olaf Weyl, the Chief Scientist at the South African Institute for Aquatic Biodiversity, and a very valued colleague, passed away this weekend. Olaf was a lead author for the IPBES assessment report on invasive alien species and an expert for the IPBES nexus assessment scoping report. His professional expertise, especially on the biology of aquatic invasions, combined with his enthusiasm and warmth, will be greatly missed by the whole IPBES community. We extend our deep condolences to his family and friends around the world.
