Current project:

Microbiomes of Zooplankton  

Zooplankton is an important component of aquatic food webs. They keep the water column clear as well as provide significant benefits to other aquatic organisms. Like plants and higher animals, zooplankton harbour a rich community of microbes. Colonization of zooplankton species by microbes has been proposed to provide numerous ecosystem services including nutrient acquisition, stress protection, detoxification and habitat provision. To date, still a lack of understanding in microbiome composition of zooplankton, zooplankton-microbe interactions in the functioning of freshwater aquatic food webs and lake biogeochemistry. We want to investigate the microbial diversity and community composition of zooplankton, phytoplankton, and bacterioplankton in different freshwater lakes. We also want to investigate the microbial community dynamics of Rotifers from resting eggs to the adult stage under sterile and non-sterile conditions using different genetic clones of Rotifers.  This project was funded by the NIOO strategic fund. This research is linked to the NIOO research theme “Microbiomes”.
