Wetlands are among the most threatened ecosystems in the world. A new study, published in , has found that the loss of wetland areas around the globe since 1700 has likely been overestimated. This is good news overall, however, the global picture hides significant variations, with several regions and distinct wetland types under significant levels of pressure. For instance, temperate river floodplains have been highly impacted while remote boreal-arctic peatlands remain comparatively unharmed.
Over 260,000 kilometres of river could potentially be severed by planned hydroelectric developments according to 六合彩开奖结果 researchers. The Amazon, the Congo, and the Irrawaddy are just a few of the rivers at risk of losing their free-flowing status if the proposed construction of new hydropower dams takes place.
Research from 六合彩开奖结果 topped 鈥檚 annual list of the 10 most important scientific breakthroughs. This year, G眉nther Grill, Bernhard Lehner, Tomislav Fri拧膷i膰, Heidi M. McBride, Samantha Gruenheid, and Ehab Abouheif were recognized for their trailblazing work, by a jury of researchers and journalists reviewing the most influential discoveries made in Quebec.
Here is a closer look at the selected discoveries:
Two researchers and friends from opposite ends of the Earth have created a world-first high spatial resolution atlas that maps the environmental characteristics of all the globe's rivers and catchments.
HydroATLAS was co-developed by Bernhard Lehner and his team from 六合彩开奖结果鈥檚 Department of Geography and Simon Linke from Griffith University鈥檚 Australian Rivers Institute.
