[Vedettes matières IGN] SylvicultureRésumé : (Auteur) Most experimental evidence on the relationship between biodiversity and ecosystem functioning comes from ecosystems with fast‐growing plants, such as grasslands. Although forests provide essential ecological services, they have been less well investigated. We used dendrochronology to compare the tree radial growth rates of four important timber species in replicated, spatially mapped stands that differed in tree composition and diversity within a central European managed forest. Growth rates differed among species but were largely unaffected by the density of neighbouring trees. Increasing stand diversity enhanced individual growth rates, after accounting for the effects of tree density and size. These increases were statistically indistinguishable among the four species. In contrast, the effects of stand and neighbourhood species composition on growth rates were non‐significant. Policy implications. Our study of long‐established central European forest stands revealed levels of tree diversity can be increased in managed forests, with the potential for modest increases in tree growth rates. These results suggest that in addition to the biodiversity and risk mitigation benefits associated with shifting practices away from monoculture management, increased carbon sequestration and yields in mature forests are likely to be realized. Our results suggest that it is possible to increase forest diversity with little or no costs to production and even with the potential for modest increases in tree growth rates.

[Termes IGN] variabilitéRésumé : (auteur) This study investigates the low-frequency (interannual and longer period) variability in three hydroclimatic records from east Central Europe. Two of these records consist of climate proxies derived from oak-tree rings in Bakta forest, and Balaton Highlands in Hungary, for the time interval 1783-2003. The third record consists of homogenized instrumental precipitation data from Budapest, Hungary, from 1842 to 2003. Using wavelet analysis, the three time series are analyzed and compared with one another. It is found that all three time series exhibit strong interannual variability at the 2-4 years timescales, and these variations occur intermittently throughout the length of each record. Significant variability is also observed in all the records at decadal timescales, but these variations persist for only two to three cycles. Wavelet coherence among the various time series is used to explore their time-varying correlation. The results reveal significant coherence at the 2-4 years band. At these timescales, the climatic variations are correlated to the tree-ring signal over different time intervals with changing phase. Increased (decreased) contribution of large-scale stratiform precipitation offers a potential explanation for enhanced (faded) coherence at the interannual timescale. Strong coherence was also observed occasionally at decadal timescales, however these coherences did not appear uniformly. These results reinforce the earlier assertion that neither the strength nor the rank of the similarity of the local hydroclimate signals is stable throughout the past two centuries.

[Vedettes matières IGN] Végétation et changement climatiqueRésumé : (auteur) In this work, an individual-based approach was used to assess the relative importance of tree age, size, and competition in modulating the individual dendroclimatic response of Quercus robur L. This was performed in a multi-aged forest in northwestern Spain under a wet Atlantic climate. All trees in five replicated forest stands with homogeneous soil conditions were mapped and inter-tree competition was quantified with a distance-dependent competition index. Tree rings of cored trees were crossdated and total age was estimated on individuals where the pith was missed. The climatic response was evaluated by bootstrapped correlations of individual tree-ring chronologies with climatic records. Inter-annual growth variation, i.e., mean sensitivity, was independent of tree age and bole diameter, but modulated by competition. Water excess in previous summer-autumn and spring negatively affected growth, while warmer September conditions favored growth. Individual response to climate was independent of tree age, but related to the joint effect of tree bole diameter and competition. Larger oaks in less competitive environments responded more plastically to climatic stress, while smaller trees under high competition levels were less responsive to climate. Strong inter-tree competition reduced growth plasticity but amplified the vulnerability of smaller oaks to the particularly rainy conditions of the study area. These findings suggest that inter-tree competition is a relevant size-mediated extrinsic factor that can potentially modulate individual radial growth variation and its response to limiting climatic conditions in temperate deciduous forests. This study highlights the value of individual-based approach as a useful tool that informs about the relative contribution of factors modulating the climatic response of tree-ring growth.

[Termes IGN] juniperus phoeniceaRésumé : (auteur) [introduction] [...] In the French Mediterranean region, populations of this Juniper tree can also grow on vertical and exposed limestone cliffs. Larson et al. (1999, 2000) assigned to cliffs the property of supporting ancient, primary or virgin woodland. In such habitats, disturbances from humans are absent, due to inaccessibility. Trees also benefit of absence of fires, grazing and competition by more aggressive level-ground vegetation. On these cliffs, in the southeast of France, Juniperus phoenicea is adapted to extreme growing conditions where the main constraints are verticality and compact hard limestone constituting a strong mechanical stress on roots. Indeed it limits their growth and both nutrients and water supply in dry and warm conditions under Mediterranean climate. In addition to that, trees face sporadic rockfall.

[Termes IGN] dendrométrieRésumé : (auteur) This publication is a result of the 13th TRACE conference (Tree Rings in Archaeology, Climatology and Ecology) organized by the Department of Department of Earth and Environmental Sciences at the University of St Andrews on May 6th – 10th, 2014 in Aviemore, Scotland, UK. TRACE is an initiative of the ‘Association of Tree-Ring Research’ (ATR) and seeks to strengthen the network and scientific exchange of scientists and students involved in the study of tree rings. The annual conference provides a scientific platform for young scientists at the cutting edge of tree-ring science. Around 110 scientists working on tree-ring related topics participated in the conference coming from Belgium, Canada, Czech Republic, France, Germany, India, Netherlands Poland, Slovenia, Spain, Sweden, Switzerland, Taiwan, United Kingdom and the United States. The participants enjoyed about 100 presentations, divided almost equally between talks and posters, organized into six thematic sessions: “Climate”, “Ecology”, “Historical”, “Wood Anatomy”, “Isotopes” and “Tree- Response”. After review, 18 short papers are published in this volume, giving an overview of the wide spectrum of different fields covered at TRACE.
