Exploring the importance of ponds

Why are ponds important? What threats do they face? And how can PONDERFUL help? Ponds have been largely overlooked but they are vital for biodiversity – and could even help us adapt to climate change. Discover more about these rich and fascinating habitats, how can they help to protect wildlife and their importance to humans as a nature-based solution. This video was created by the PONDERFUL project and received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 869296.

Join the AQUACOSM network

AQUACOSM is an integrated, international network of experimental infrastructures of 21 marine and freshwater research institutes. The goal of this networking is a better coordination of future research projects, joint developing of best practices and opening of the mesocosms of both fresh water and marine research institutes for international, interdisciplinary cooperation.

Climate change drives widespread shifts in lake thermal habitat

Global warming is increasing the temperatures of lakes worldwide. Benjamin Kraemer teamed up with colleagues to quantify the long-term temperature changes in 139 lakes worldwide. They analysed shifts in thermal habitats – the temperature conditions needed by species to survive – and found that as lakes warm, species will need to shift to different depths or seasons.
