The Group on Earth Observations Biodiversity Observation Network
GEO BON is continuously building up its network. GEO BON has more than 1000 individual members from over 100 different countries, including scientists, managers and practitioners active in biodiversity observation.
The dynamics of species populations, i.e. the variation of species geographic distributions and abundances in space and time, represent one of the most fundamental aspects of biodiversity and its change.
In the past 20 years, work on ecosystem services has focused primarily on recognizing the multiple types of services that exist, in trying to quantify their temporal and spatial variations, and recognizing the numerous trade-offs that emerge when considering more than one service.
