Im hohen Norden des Planeten hinterlässt der Klimawandel besonders deutliche Spuren. Eine neue Studie in Finnland zeigt nun, dass es parallel dazu dramatische Veränderungen bei den bestäubenden Insekten gegeben hat. Forscherinnen der Martin-Luther-Universität Halle-Wittenberg (MLU), des Helmholtz-Zentrums für Umweltforschung (UFZ) und des Deutschen Zentrums für integrative Biodiversitätsforschung Halle-Jena-Leipzig (iDiv) haben festgestellt, dass sich das Netzwerk von Pflanzen und ihren Bestäubern dort seit dem Ende des 19. Jahrhunderts massiv verändert hat. Möglicherweise könne das dazu führen, dass Pflanzen künftig weniger effektiv bestäubt werden und sich dadurch schlechter vermehren, warnen die Wissenschaftlerinnen im Fachjournal Nature Ecology & Evolution.
