  Evaluating Dryocosmus Kuriphilus-induced Damage on Castanea Sativa Eric Gehring^1,2, Bruno Bellosi¹, Ambra Quacchia¹, Marco Conedera^{1 1}Insubric Ecosystem Research Group, WSL Swiss Federal Research Institute, ²Laboratory of Soil Biodiversity, Université de Neuchâtel It is common practice to assess the damage caused by Dryocosmus kuriphilus by considering the abundance of galls alone rather than by also taking related branch corruption into consideration. We propose a composite damage index that takes into account the most important branch features, thus enabling more realistic damage assessment.

  A Technical Perspective in Modern Tree-ring Research - How to Overcome Dendroecological and Wood Anatomical Challenges Holger Gärtner¹, Paolo Cherubini¹, Patrick Fonti¹, Georg von Arx¹, Loïc Schneider¹, Daniel Nievergelt¹, Anne Verstege¹, Alexander Bast¹, Fritz H. Schweingruber¹, Ulf Büntgen^{1 1}Landscape Dynamics / Dendroecology, Swiss Federal Research Institute WSL Here we present a protocol outlining how to sample wooden specimens for the overall assessment of their growth structures. Macro- and microscopic preparation and visualization techniques necessary to generate well-replicated and highly resolved wood anatomical and dendroecological dataset, are described are described.
