For the past 25 years, researchers have carried out measurements of the climate and environment in East Greenland. This has resulted in an extremely valuable time series of many different data – primarily on the Zackenberg/Daneborg area and within the framework of the Greenland Ecosystem Monitoring (GEM) program. Presently, researchers at the Arctic Research Centre, Aarhus University, are setting up advanced autonomous measurement stations that expand the data coverage and manage themselves all year round.

Biologists from Aarhus University and the University of Copenhagen have studied the environmental DNA in water samples collected simultaneously by 370 volunteers on two occasions from almost 100 sites along the Danish coast. The combination of citizen science and environmental DNA has provided an effective overview of biodiversity in Danish coastal waters.

In the Mojave and Sonoran deserts, feral donkeys and horses dig wells that are sometimes as deep as two meters. These wells, though being the product of invasive species, actually benefit the ecosystem greatly.
