Bacteria are often exposed to heavy metals in their environment, which leads to bacterial stress due to their toxicity. In our study we were able to show that increased concentrations can promote metal tolerance of Staphylococcus aureus . Adaptation occurs through spontaneous mutations in specific genes. Therefore, potentially every S. aureus can become tolerant to metals, leading to reduced effectiveness of these antibacteria...

The physical effects of climate warming have been well documented, but the biological responses are far less well known, especially at the ecosystem level and at large (intercontinental) scales. Global warming over the next century is generally predicted to reduce food web complexity, but this is rarely tested empirically due to the dearth of studies isolating the effects of temperature on complex natural food webs. To overcom...
