Are mature forests carbon limited? To explore this question, we exposed ca. 110-year-old, 40-m tall Picea abies trees to a 550-ppm CO2 concentration in a mixed lowland forest in NW Switzerland. The site receives substantial soluble nitrogen (N) via atmospheric deposition, and thus, trees are unlikely N-limited. We used a construction crane to operate the free-air CO2 release system and for canopy access. Here, we summarize the major results for growth and carbon (C) fluxes....

1.There is increasing evidence that species diversity enhances the temporal stability of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony in species responses to environmental conditions was found to be one of the main drivers of this stabilizing process. However, the effect of species mixing on the stability of productivity, and the relative importance of the associated mechanisms, remain poorly understood in forest...

Data from: EuMIXFOR empirical forest mensuration and ring width data from pure and mixed stands of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) through Europe

Michael Heym, Ricardo Ruíz-Peinado, Miren Del Río, Kamil Bielak, David I. Forrester, Gerald Dirnberger, Ignacio Barbeito, Gediminas Brazaitis, Indrė Ruškytė, Lluís Coll, Marek Fabrika, Lars Drössler, Magnus Löf, Hubert Sterba, Václav Hurt, Viktor Kurylak, Fabio Lombardi, Dejan Stojanović, Jan Den Ouden, Renzo Motta, Maciej Pach, Jerzy Skrzyszewski, Quentin Ponette, Géraud De Streel, Vit Sramek … & Hans Pretzsch
This data set provides unique empirical data from triplets of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) across Europe. Dendrometric variables are provided for 32 triplets, 96 plots, 7555 trees and 4695 core samples. These data contribute to our understanding of mixed stand dynamics.

Wood anatomy of Indian oaks, with reference to systematic, ecological and evolutionary perspectives

Prachi Gupta & Sangeeta Gupta
The present study provides a comprehensive wood microstructure analysis of 16 species of the genus Quercus inhabiting the Himalayan region of India. Indian oaks can be categorised into two groups: Ring porous oaks and diffuse porous oaks. Most of the diffuse porous oaks were quite homogenous in their microstructure and showed slight variations in ray cellular composition and axial parenchyma distribution. The results revealed that the current classification of Quercus is not in concordance with...

Data from: The importance of individual heterogeneity for interpreting faecal glucocorticoid metabolite levels in wildlife studies

Joy Coppes, Jim-Lino Kämmerle, Mirjam Willert, Annette Kohnen, Rupert Palme & Veronika Braunisch
1. Being a non-invasive and inexpensive method, the analysis of faecal corticosteroid metabolites (FCM) is increasingly being applied in wildlife research. Various environmental factors have been shown to influence FCM levels, but most studies did not account for inter-individual variance, which we hypothesized may substantially affect the results. 2. We combined FCM analysis with genetic analysis to identify the sex and individual of samples collected in three consecutive winters, with repeated samples per individual, across...
