Di 24. Januar 10:00, Engler Die nächste Gradation des Lärchenwicklers wird erwartet (35') Beat Forster, WSL
    Alle zehn Jahre steigt die Population des Lärchenwicklers (Zeiraphera griseana) in den inneralpinen Tälern deutlich an. Wie eine Welle zieht die Massenvermehrung jeweils von West nach Ost durch den Alpenraum. Eine neue Gradation hat in Frankreich begonnen. Wird sie so ablaufen wie in früheren Jahrzehnten oder wird eine Beeinflussung durch die Klimaerwärmung immer deutlicher?  
Mo 13. März 10:00, Flury Stitching together ‘big data’ sources: a pan-European fungal meta-database that addresses contemporary questions in ecology and global change biology (35'+15') Carrie Andrew, WSL
    Species occurrence observations from citizen science projects, herbaria, and the digitization of museum records represent a largely underutilized ecological resource. Yet there is unparalleled potential for understanding many aspects of the ecology and biogeography of organisms with these data. This talk demonstrates how such continental-scale meta-databases, in this case a pan-European mycological one (ClimFun), offer unique insights into climate change effects on phenology in recent decades.  
Di 11. April 10:00, Engler Introduced tree species in European forests – Opportunities and challenges (45'+15') Frank Krumm, WSL
    An emotional discussion across Europe is dominating the debate among non-native tree species. Varying definitions of specific terms, social perception – often based on different historic backgrounds, political and economic influences and finally fast environmental changes that are often too fast for basic research activities to provide scientific consultation. The project In-Tree aimed to create a compilation of chapters highlighting some of the major aspects of the topic of introduced tree species within a European context. The presented findings are based on sound scientific studies as well as on reliable examples from practice. The main final product is a book where 90 authors from 45 different institutions and 18 countries have contributed their expertise - some are forestry practitioners actively engaged in forest management, while others are researchers, others are civil servants, and others work for non-governmental agencies focusing on natural sciences. The variety of expertise amongst the authors ranges from nature conservation to forestry, but authors from  social sciences and invasion ecology have also contributed.

The book has been translated into German language and as a further outcome of the project that has been funded by the German Ministry of Food and Agriculture, a policy brief has been produced that appeared in 6 different languages and aims to provide policy makers the essentials of the book publication.

Di 16. Mai 10:00, Flury The new stable isotope research lab at WSL (35+15') Matthias Saurer, WSL
    Recently, the stable isotope lab of PSI was transferred to WSL. This opens new possibilities for WSL researchers to apply the cutting edge technology of compound-specific isotope analysis and expands the capacity for bulk isotope analysis already available at WSL Zentrallabor. In this talk, background information on stable isotopes is given, the new facilities are presented, and research opportunities discussed. It will be shown that stable isotopes are very helpful to improve our understanding of physiological and biochemical responses of trees to environmental conditions and thus their adaptation/acclimation potential to changing climate conditions.  
Di 20. Juni 10:00, Engler From Waldsterben to Klimawandel - changing perspective on forest monitoring and inventorying (45'+15') Marco Ferretti, WSL
    Information about forest resources was traditionally based on national forest inventories (NFIs). Starting in the 1970s, emerging environmental concerns make also monitoring to become a popular investigation approach across the forest community. Since then, forest inventory and forest monitoring developed rather independently across Europe, up to the point to be perceived and implemented as two separate, sometimes competing systems.
Scientific and political priorities (e.g. from forest decline to climate change) and spatial and temporal scales (e.g. from national to global) of concern have changed a lot over the past 40 years. Alongside, the demand for multidisciplinary, comparable, long-term, multiscale, high-quality data on forest ecosystem status and changes has increased. As a result, the dualism between forest inventorying and forest monitoring sounds quite obsolete now. Rather, a conceptual and functional integration between forest inventory and forest monitoring is essential.
