We present and discuss latest research on phenology in our monthly seminar. Please contact if you would like to join this online event.

PhenObs - an international project about phenology of herbaceous plants

Prof. Christine Römermann talks about the PhenObs project and it's linkages with other iDiv projects and plattforms. Get a first insight view of the great scientific opportunities at iDiv within the framework of the PhenObs project.

Contribution from Vienna: PhenObs at "KlimaheldInnen"

Barbara Knickmann from the Botanical Garden in Vienna talks about the PhenObs project and why it is important to have research on phenology of herbaceous plants in times of climate change.
