The study also finds that freshwater megafauna diversity is higher in future fragmented free-flowing rivers than in rivers that would remain free-flowing in the future or that are already fragmented. 30 September 2021 press release The principle of aquaponics – clearly defined Missing or vague definitions and standards make it difficult to plan and evaluate aquaponic systems properly. Researchers from IGB have now tightened up the definitions and created a calculation model for resource use. 22 September 2021 press release Aquatic insects are sensitive to light pollution New research from IGB shows that current strategies for reducing the impact of light pollution do not go far enough in protecting aquatic insect species. 9 September 2021 press release German federal elections: researchers recommend a more sustainable water policy In the latest IGB Policy Brief on the occasion of the 2021 federal elections, scientists recommend that politicians take urgent measures to combat the massive decline in freshwater biodiversity and thus safeguard important ecosystem services. 17 August 2021 press release Against overfishing: Protect large spawners and assess stocks correctly Recent study with Robert Arlinghaus shows that the replenishment potential of many fish stocks is overestimated. This increases the risk of overfishing. Especially the largest fish should be protected to a greater degree than is presently the case. 28 July 2021 press release Blue waters – green beaches: benthic filamentous algae are an emerging threat to clear lakes worldwide Many of the world's clear lakes are deteriorating at an alarming rate: at the shore, where people want to play and swim, the lake bottom is covered with green carpets of algae. 14 July 2021 press release New insights for species conservation Using water fleas, Luc De Meester showed that a population with a high amount of genetic variation can quickly adapt its behavioural and life-history traits to changes in the environment. 11 June 2021 press release Why do people support fish species conservation in European rivers? In Germany, the protection of fish is supported by general pro-ecological values and norms. In France, Sweden and Norway, on the other hand, native fish species have great influence on individual conservation-oriented behaviour. 3 June 2021 press release Lake habitats are disappearing as the climate changes Global warming is increasing the surface temperatures of lakes worldwide – are species finding the temperatures they need to survive? Researchers led by IGB have quantified the long-term temperature changes in 139 lakes worldwide. 2 June 2021 press release Global warming: lakes lose too much oxygen Oxygen levels in freshwater lakes are declining rapidly – faster than in the oceans. Over the past forty years, for example, oxygen levels in the deep waters of temperate lakes have dropped by nearly 19 percent.
