For a fantastically picturesque train ride, consider travelling by rail between Lanquart and Davos (in Switzerland). You’ll be rewarded with stunning Alpine views, especially in autumn when the Larches, surrounded by Spruces, turn yellow and cast pretty reflections in the waters of the mountain lakes. Seen here is Schwartzsee, located only a few meters from ‘Davos Laret’ train station. Imaggeo is ...[Read More]

The introduction of alien species, as these translocated taxa are known, has wide ranging implications for native biota, ecosystem functioning, human health and the economy. Research published earlier this year found that during the last 200 year ...[Read More]

A new study, published in the EGU’s open access journal Earth System Dynamics, reports on concentratio ...[Read More]
