A team of Czech, Spanish and British scientists has produced the first map to outline the level of alien plant invasions across the European Union. The researchers said biological invasions are one of the major threats to biodiversity and also affect the economy and human health.
New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration.
Biological invasions are one of the major threats to biodiversity and in many cases they have considerable impact on economy and human health.
Marginal plants, particularly trees, play a crucial role in sustaining the biodiversity of Europe's big river systems, according to a recently held workshop organized by the European Science Foundation (ESF).
New North African climate reconstructions reveal three â€˜green Saharaâ€™ episodes during which the present-day Sahara Desert was almost completely covered with extensive grasslands, lakes and ponds over the course of the last 120.000 years.
A geographer from the University of Leicester has produced for the first time a map of the scorched Earth for every year since the turn of the Millennium.

The first soil moisture maps with a spatial resolution of one km are available online for the entire southern African subcontinent. As soil moisture plays an important role in the global water cycle, these maps, based on data from ESAâ€™s Envisat satellite, will lead to better weather and extreme-event forecasting, such as floods and droughts.
