Zentralanstalt für Meteorologie und Geodynamik Folie 2 OUTLINE Definition History of phenological research and networks Motivation of Global Phenology Data Status Quo of GPD Potential applications Major results of recent phenological studies

Zentralanstalt für Meteorologie und Geodynamik Folie 3 DEFINITION Phenology is the study of the timing of recurring biological events in the animal and plant world Examples: Leaf unfolding and flowering of plants in spring, fruit ripening, colour changing and leaf fall in autumn, as well as the appearance and departure of migrating birds and the timing of animal breeding are all examples.

Zentralanstalt für Meteorologie und Geodynamik Folie 5 HISTORY OF PHENOLOGICAL RESEARCH AND NETWORKS Carolus Linnaeus In Philosophia Botanica, 1751 he outlined methods for compiling annual plant calendars of leaf opening, flowering, fruiting and leaf fall, together with climatological observations so as to show how areas differ… First known phenological network in Sweden and Finland

Zentralanstalt für Meteorologie und Geodynamik Folie 8 MOTIVATION OF GLOBAL PHENOLOGY DATA phenology has rapidly become an important tool for climate change impact studies (IPCC, 2007) long phenological records are existing plant development in mid and high latitude climate region is strongly dependant on temperature thus plant development esp. in spring is an indicator for climate warming and climate change & impacts can be communicated to the public very effectively via phenology earlier onset of spring is much more as phenological events can be observed rather easily observations can be carried out by citizen scientits
