Coastal ecosystems deteriorate globally due to human-induced stress factors, like nutrient loading and pollution. Bacteria are critical to marine ecosystems, e.g., by regulating nutrient cycles, synthesizing vitamins, or degrading pollutants, thereby providing essential ecosystem services ultimately affecting economic activities. Yet, until now bacteria are overlooked both as mediators and indicators of ecosystem health, mainly due to methodological limitations in assessing bacterial ecosystem functions. However, these limitations are largely overcome by the advances in molecular biology and bioinformatics methods for characterizing the genetics that underlie functional traits of key bacterial populations – “key” in providing important ecosystem services, being abundant, or by possessing high metabolic rates. It is therefore timely to analyze and define the functional responses of bacteria to human-induced effects on coastal ecosystem health. We posit that categorizing the responses of key marine bacterial populations to changes in environmental conditions through modern microbial oceanography methods will allow establishing the nascent field of genetic counselling for our coastal waters. This requires systematic field studies of linkages between functional traits of key bacterial populations and their ecosystem functions in coastal seas, complemented with systematic experimental analyses of the responses to different stressors. Research and training in environmental management along with dissemination of results and dialogue with societal actors are equally important to ensure the role of bacteria is understood as fundamentally important for coastal ecosystems. Using the responses of microorganisms as a tool to develop genetic counselling for coastal ecosystems can ultimately allow for integrating bacteria as indicators of environmental change., Coastal ecosystems deteriorate globally due to human-induced stress factors, like nutrient loading and pollution.

Der Einsatz von Plastik gehört zu den großen Errungenschaften unserer Zeit. Die Nutzung von Plastik in unseren verschiedenen Lebensbereichen ermöglicht uns heute Vieles. Dabei setzen wir Plastik oft ein, ohne dass uns dies bewusst ist. Wieviel „virtuelles Plastik“ war allein notwendig, um diesen Synthesebericht zu erstellen? Wieviel Plastik benötigen Sie gerade, um diesen Synthesebericht zu lesen? Wie so oft, so hat auch der Einsatz von Plastik zwei Seiten: den positiven Errungenschaften stehen negative Auswirkungen gegenüber, vor allem nach der Nutzung von Plastik. Im Fokus stehen hierbei Fragestellungen der Toxikologie sowie der Abfallverwertung. Im Gegensatz zu vielen anderen Stoffen, mit denen wir täglich in Berührung sind, hat Plastik die Eigenschaft, dass sich kleinste Partikel bilden. So ist es nicht verwunderlich, dass sich mittlerweile in allen Umweltmedien Mikroplastikpartikel finden lassen. Die Idee von PLASTRAT war es, in einem interdisziplinären Team Ansätze für die Verminderung von Einträgen von Plastik in Gewässer zu untersuchen. Dabei standen über den Ansatz der systemischen Risikoanalyse die unterschiedlichen Sektoren im Fokus, angefangen von der Erzeugung, über die Nutzung bis hin zu den Eintragspfaden und die toxikologische Bewertung. Der Synthesebericht fasst die Ergebnisse von PLASTRAT zusammen. Vor allem zeigt der Synthesebericht die großen Herausforderungen sowie Lösungsansätze zum Thema Mikroplastik auf. Dabei wird auch deutlich, dass wir bei vielen Fragestellungen zum Umgang mit Plastik erst am Anfang stehen. Die ersten Ideen zu PLASTRAT entstanden 2016. In den vergangenen fünf Jahren stand das Thema Plastik im Fokus von Öffentlichkeit und Presse. In dieser Zeit gab es bereits wichtige Veränderungen beim Einsatz von Plastik bei diversen Produkten, beispielsweise durch die Substitution durch alternative Materialien. Dies zeigt deutlich, dass eine Bewusstseinsveränderung stattgefunden hat, die sich sicherlich in der Zukunft fortsetzten wird. D
