Rapid evolution under climate change
Rapid evolution under climate change
Ecosystems are threatened worldwide by rapid climate change. Plants play a critical role in all ecosystems because they are at the basis of all food webs. For many regions that are already very dry today, such as deserts or semi-deserts, climate scenarios predict even lower precipitation levels. A team of researchers led by Katja Tielbörger from the University of Tübingen has now discovered that certain plant species can evolve very quickly under drought conditions.

Findings From Experimental Biodiversity Sites Are Reliable
Findings From Experimental Biodiversity Sites Are Reliable
Much of our knowledge of how biodiversity benefits ecosystems comes from experimental sites. These sites contain combinations of species that are not found in the real world, which has led some ecologists to question the findings from biodiversity experiments. But the positive effects of biodiversity for the functioning of ecosystems are more than an artefact of experimental design.

Artificial Carbohydrates for Sustainable Food Production
What alternatives to conventional agriculture exist to produce carbohydrates for food and feed? Scientists at Heidelberg University performed model calculations for artificial sugar production with a view towards synthesis of other carbohydrates such as starch. They are looking into whether a part of the human calorie requirement could be met by resource-saving, synthetically produced foods.

Antidepressants Make Fish Easy Prey: Loss of Natural Reaction to Stress
Antidepressants Make Fish Easy Prey: Loss of Natural Reaction to Stress
Residues of pharmaceuticals in surface waters - in this case an antidiabetic and two antidepressants - also have effects on fish. Drugs for the treatment of depression have particularly strong effects, with fish losing their natural reaction to stress when substance concentration in the water is above a certain level.

Chemicals Inhibit Decomposition Processes - by Damaging Biodiversity
Chemicals Inhibit Decomposition Processes - by Damaging Biodiversity
Declines in the diversity and abundance of decomposers explain reductions in plant decay rates under the influence of chemical stressors, but not added nutrients. These are the new insights of a study published in the open access journal eLife. The global meta-analysis conducted by researchers at the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL) and the University of Namur in Belgium highlights the main anthropogenic effects on the biodiversity and functioning of ecosystems, and thus helps predicting the fate of different ecosystems around the world.

Identifying the Blind Spots of Soil Biodiversity
Identifying the Blind Spots of Soil Biodiversity
Soils harbour a substantial part of the world's biodiversity, yet data on the patterns and processes taking place below ground does not represent all relevant ecosystems and taxa. For example, tropical and subtropical regions largely remain a blind spot when it comes to soil biodiversity. This is one of the results of a new study published and led by scientists from the German Centre for Integrative Biodiversity Research, the Martin Luther University Halle-Wittenberg and Leipzig University.

Smaller habitats worse than expected for biodiversity
Smaller habitats worse than expected for biodiversity
New international research breaks ground for the next generation of biodiversity forecasts No 131/2020 from Jul 29, 2020 Biodiversity's ongoing global decline has prompted policies to protect and restore habitats to minimize animal and plant extinctions. However, biodiversity forecasts used to inform these policies are usually based on assumptions of a simple theoretical model describing how the number of species changes with the amount of habitat.

Restoring Nature
Restoring Nature
An abandoned space in the middle of Münster: in the historic medicinal plant garden, which hasn't been in use since 2016, nature can pretty much do what it likes. At least, it almost can - anyone who fights their way through an overgrown meadow between Einsteinstraße and Schlossgräfte will come across a clearing, about 50 square metres in size, on which meadow plants are arranged in rows of pots standing on black groundsheets.

Cavefish have fewer cells of the innate immune system
Cavefish have fewer cells of the innate immune system
Adaptation of cavefish to low-parasite environment may provide autoimmune disease insight / Study published in "Nature Ecology & Evolution" Cavefish are small, live in tucked away places humans rarely go, and they're common enough that you can find them on every continent except Antarctica. But they also have another characteristic that seems surprising at first glance: They can tell researchers something about the occurrence of autoimmune diseases in humans.

Long-Term Consequences Difficult to Predict
Long-Term Consequences Difficult to Predict
In a longitudinal study, an international research team led by Leipzig University has investigated the consequences of changes in plant biodiversity for the functioning of ecosystems. The scientists found that the relationships between plant traits and ecosystem functions change from year to year. This makes predicting the long-term consequences of biodiversity change extremely difficult, they write in "Nature Ecology & Evolution".

Wild bees depend on the landscape structure
Research team led by University of Göttingen investigates flower strips, organic farming and small crop fields Sowing strips of wildflowers along conventional cereal fields and the increased density of flowers in organic farming encourage bumblebees as well as solitary wild bees and hoverflies. Bumblebee colonies benefit from flower strips along small fields, but in organic farming, they benefit from large fields.

How much forest does biodiversity need in cultivated landscapes?
Research team with Göttingen participation develops concepts to promote biodiversity Forests, especially in the tropics, are home to the world's greatest biodiversity, but are threatened by increasing land use. An international research team with participation of the University of Göttingen has investigated how high the proportion of forest in cultivated landscapes must be in order to protect the greatest number of animal and plant species that depend on this habitat.

Coffee, cocoa and vanilla: an opportunity for more trees in tropical agricultural landscapes
Coffee, cocoa and vanilla: an opportunity for more trees in tropical agricultural landscapes
Research team from Göttingen University investigates the land-use history of agroforestry systems The cultivation of coffee, cocoa and vanilla secures the income of many small-holder farmers and is also a driver of land-use change in many tropical countries. In particular, cultivation in agroforestry systems, in which these crops are combined with trees that provide shade, is often considered to have great potential for ecologically sustainable cultivation.
