Twenty years ago, the first NEOBIOTA Conference has been organised. During this period, our comprehension on alien species is continuously increases. Same as the number of challenges caused by the alien species. Humans, as driving force and main ecological engineer nowadays, play a crucial role in alien species invasions as well. A role that has two faces or two mutually opposite characters, just as was the case of Dr. Jekyll and Mr. Hyde in Robert Louis Stevenson’s novella. We are responsible for the dispersal of alien species (on purpose or accidentally), and creating (disturbed) habitats that are suitable for alien species to become invasive. However, we also are trying to manage and control them, to increase public awareness and increase citizen science activities. Because all of these, and much more, we put central focus on human role in biological invasions. Looking forward to host you in enchanting Croatia at the 11th International Conference on Biological Invasions,
On behalf of the Local Organising Committee Sven Jelaska
