No life has yet been found on Mars, but it is exciting to explore under what circumstances it might be possible. A team has studied the cellular processes that regulate the adaptation of microorganisms to perchlorates. If microorganisms could genetically adapt their stress response to this salt, which occurs in some deserts and on Mars, their survival on the red planet would be possible.

Today, the second part of the UN Biodiversity Conference (CBD COP 15) starts in Montreal. In previous negotiations, inland waters have not been given sufficient consideration – even though they harbour a particularly high biodiversity and provide vital ecosystem services for humans. IGB scientists researching freshwater biodiversity provide an overview of this often overlooked topic.

Robert Arlinghaus and his team have received this year's Inter Circle U Prize for their engagement in sustainable fisheries research.

The quality of lake ice is of paramount importance for ice safety and lake ecology under ice, but its temporal and spatial variability is largely unknown. An international research team with IGB researcher Hans-Peter Grossart conducted a coordinated sampling campaign of lake ice quality throughout the Northern Hemisphere. The team, led by Sweden's Uppsala University, was able to show that lake ice during this period generally consisted of unstable white ice, which at times accounted for up to 100 percent of the total ice thickness.

Studies of the Anthropocene continue to uncover the complex and dynamic interrelations between the societal world and the Earth system. At an international conference, researchers from the natural sciences, engineering, social sciences and humanities have joined forces to address the question of how these increasing mutual impacts can be better understood and further developed towards global sustainability.

Researchers from IGB and the Adam Mickiewicz University (AMU) in Poznań (Poland) tested whether water fleas (Daphnia) are more frequently infected by the parasite Caullerya mesnili in warmer waters. For the infected water fleas, the disease usually ends fatally.

Do fishing clubs take their responsibility seriously at artificial gravel pit lakes? Researchers compared managed and unmanaged natural lakes as well as managed and unmanaged gravel pit lakes in Lower Saxony and Brandenburg. They found that lakes managed by anglers host similar fish species to unmanaged natural lakes.

A team of researchers from IGB and the Cluster of Excellence "Science of Intelligence" at the Humboldt University zu Berlin has now shown for the first time in naturally clonal fish that genetically identical individuals already differ in their character traits on the first day of life and that these early character differences significantly shape the behavior of the animals into adulthood. The study was published in the journal Nature Communications.
