Toelichting (Engels) Planktonic interactions are variable and complex. We are now more aware of infochemicals involved in planktonic interactions and have started to accumulate knowledge about their nature. Nonetheless, we are still not able to identify and isolate these infochemicals. Chemical communication appears to mediate both predation and interspecific competition, and we know that induced defences moderate strong population fluctuations and the local extinctions of consumers that may result. We do not yet know, however, what and how much impact chemical communication has on ecosystem functioning. One may pothesize that chemical interactions between planktonic organisms hamper lake restoration by food-web, manipulation, but to test this field studies are necessary. Last but not least, freshwater chemical ecology still lags behind its terrestrial and marine counterparts. The author believes that future research in chemical ecology will help pave the way for a better understanding of species composition, top-down control of algae and the structure of aquatic food webs

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
