Plants

The vegetation is the basis of all ecosystems. We therefore, in collaboration with the Dutch Plant Society (Floron) have precisely assessed what plant species are present at our study sites, before the lights went on. At the end of the experiment, this assessment is repeated and structural differences in plant composition, as a result of light treatment, can be identified.
In addition, we study changes in seasonal timing in pants – many plants use day length as a cue for leaf production, leaf loss, and flowering. Every year, we monitor the timing of those processes and measure differences in timing as a result of light exposure.

Not only animals may change their temporal behaviour in response to light - plants may flower at a different time of year, and keep their leaves longer. At our sites, we look at the phenology of plants.
