Due to global trade the number of alien species has exponentially increased, a trend that is especially evident in aquatic ecosystems. Today more than 400 alien aquatic and semi-aquatic plant species for aquarium or pond purposes are in trade in Europe causing a diverse impact on aquatic biodiversity.

Iris Stiers focused her PhD on these invasive alien freshwater aquatic plants. The main goal was to strengthen the understanding of a number of target Invasive Alien Aquatic Plants (IAAPs), how they interact with the different biological communities and what the role is of invasive species cover in shaping the impact.

In her post-doc she continues to work on the impact of IAAPs and collaborates with several institutions (European Plant Protection Organization (EPPO); Norwegian Scientific Committee for Food Safety (VKM)) and research groups in Europe, USA, South-Africa and New Zealand to conduct risk analyses and meta-analyses on the impact and management of different IAAPs. More recently she broadened her research to investigate the functional role of native and invasive macrophytes.

Iris Stiers is also the academic coordinator of the programme Master in Biology – specialisation human ecology.
