Lakes in alpine locations react sensitively to climate change. Researchers led by IGB and the Faculty of Geosciences at Southwest Jiaotong University in Chengdu, China, have analysed in detail the changes in a lake in the northern Tibetan highlands since the end of the last ice age. Sediment samples dating back thousands of years show strong ecological changes due to rising temperatures and the influence of melting glaciers. 

Justyna Wolinska has successfully passed the six-year tenure track phase, and has now been jointly appointed to a permanent professorship for Aquatic Evolutionary Ecology by IGB and Freie Universität Berlin.

The World Climate Summit in Glasgow recently ended and climate protection is also to be given greater priority in Germany. Rita Adrian, Sonja Jähnig and Mark Gessner from IGB shed light on what climate change and the current political discourse mean for inland waters and aquatic biodiversity.

What happens in water bodies when the water goes and comes back? Dr. Maria Isabel Arce has shown on a lowland river that after drying up and raining, rivers can release more carbon dioxide and methane.

In the run-up to the UN Climate Change Conference, scientific societies in the field of water research once again recommend that the high relevance of inland waters should be better taken into account in the context of climate policy. The scientific findings and data from IGB also prove this urgency.

The populations of all reptile species and almost all amphibian species have declined over the past 120 years. Amphibians are particularly sensitive indicators of the state of our ecosystems. One of the Red List species experts is IGB researcher Matthias Stöck.

July and August brought heavy rain and flooding in some places. More than enough precipitation to make up for the recent dry years, one might think. But it is not that simple! IGB researchers show that groundwater levels and soil moisture remain below normal.

Excessive phosphorus loading lead to the accumulation of this nutrient in water bodies. Lake sediments can retain phosphorus. In laboratory tests, an IGB team has investigated the conditions under which this retention is long-term.
