Data from: Spatial structure of above-ground biomass limits accuracy of carbon mapping in rainforest but large scale forest inventories can help to overcomeStéphane Guitet, Bruno Hérault, Quentin Molto, Olivier Brunaux & Pierre Couteron
Precise mapping of above-ground biomass (AGB) is a major challenge for the success of REDD+ processes in tropical rainforest. The usual mapping methods are based on two hypotheses: a large and long-ranged spatial autocorrelation and a strong environment influence at the regional scale. However, there are no studies of the spatial structure of AGB at the landscapes scale to support these assumptions. We studied spatial variation in AGB at various scales using two large forest...
Data from: Forest plant community as a driver of soil biodiversity: experimental evidence from collembolan assemblages through large-scale and long-term removal of oak canopy trees Quercus petraeaLudovic Henneron, Michaël Aubert, Fréderic Archaux, Fabrice Bureau, Yann Dumas, François Ningre, Claudine Richter, Philippe Balandier & Matthieu Chauvat
Plant–soil interactions are increasingly recognized to play a major role in terrestrial ecosystems functioning. However, few studies to date have focused on slow dynamic ecosystems such as forests. As they are vertically stratified by multiple vegetation strata, canopy tree removal by thinning operations could alter forest plant community through tree canopy opening. Very little is known about cascading effects on soil biodiversity. We conducted a large-scale, multi-site assessment of collembolan assemblage response to long-term canopy...

1. Patterns of actuarial senescence can be highly variable among species. Previous comparative analyses revealed that both age at the onset of senescence and rates of senescence are linked to species position along the fast-slow life-history continuum. As there are few long-term datasets of wild populations with known-age individuals, intraspecific (i.e. between-population) variation in senescence is understudied and limited to comparisons of wild and captive populations of the same species, mostly birds and mammals. 2....
Data from: Environment and host as large-scale controls of ectomycorrhizal fungiSietse Van Der Linde, Laura M. Suz, C. David L. Orme, Filipa Cox, Henning Andreae, Endla Asi, Bonnie Atkinson, Sue Benham, Christopher Carroll, Nathalie Cools, Bruno De Vos, Hans-Peter Dietrich, Johannes Eichhorn, Joachim Germann, Tine Grebenc, Hyun S. Gweon, Karin Hansen, Frank Jacob, Ferdinand Kristöfel, Pawel Lech, Miklos Manninger, Jan Martin, Henning Meesenburg, Päivi Merilä, Manuel Nicolas … & Martin I. Bidartondo
Explaining the large-scale diversity of soil organisms that drive biogeochemical processes—and their responses to environmental change—is critical. However, identifying consistent drivers of belowground diversity and abundance for some soil organisms at large spatial scales remains problematic. Here we investigate a major guild, the ectomycorrhizal fungi, across European forests at a spatial scale and resolution that is—to our knowledge—unprecedented, to explore key biotic and abiotic predictors of ectomycorrhizal diversity and to identify dominant responses and thresholds...
Data from: Plant interactions as biotic drivers of plasticity in leaf litter traits and decomposability of Quercus petraeaLudovic Henneron, Matthieu Chauvat, Frédéric Archaux, Marthe Akpa-Vinceslas, Fabrice Bureau, Yann Dumas, Laurent Mignot, François Ningre, Sandrine Perret, Claudine Richter, Philippe Balandier & Michael Aubert
The importance of plant litter traits and decomposability for nutrient cycling processes and plant community dynamics through plant-litter-soil feedbacks has been largely emphasized. However, the role of biotic interactions as drivers of intraspecific variability in litter traits remains surprisingly little studied. In this study, we used a large-scale, multi-site network of long-term tree removal experiments manipulating the abundance of a foundation tree species, i.e. Quercus petraea, to assess how plant interactions control intraspecific variation in...
Data from: Flower phenology as a disruptor of the fruiting dynamics in temperate oak speciesEliane Schermer, Marie-Claude Bel-Venner, Jean-Michel Gaillard, Stéphane Dray, Vincent Boulanger, Iris Le Roncé, Gilles Oliver, Isabelle Chuine, Sylvain Delzon & Samuel Venner
Many perennial plants display masting, i.e., fruiting with strong interannual variations, irregular and synchronized between trees within the population. Here, we tested the hypothesis that the early flower phenology in temperate oak species promotes stochasticity into their fruiting dynamics, which could play a major role in tree reproductive success. From large field monitoring network, we compared the pollen phenology between temperate and Mediterranean oak species. Then, focusing on temperate oak species, we explored the influence...
Data from: Biological traits, rather than environment, shape detection curves of large vertebrates in neotropical rainforestsThomas Denis, Cécile Richard-Hansen, Olivier Brunaux, Marie-Pierre Etienne, Stéphane Guitet & Bruno Hérault
Line transect surveys are widely used in neotropical rainforests to estimate the population abundance of medium- and large-sized vertebrates. The use of indices such as Encounter Rate has been criticized because the probability of animal detection may fluctuate due to the heterogeneity of environmental conditions among sites. In addition, the morphological and behavioral characteristics (biological traits) of species affect their detectability. In this study, we compared the extent to which environmental conditions and species’ biological...
Data from: Forest management adaptation to climate change: a Cornelian dilemma between drought resistance and soil macro-detritivore functional diversityLudovic Henneron, Michaël Aubert, Fabrice Bureau, Yann Dumas, François Ningre, Sandrine Perret, Claudine Richter, Philippe Balandier & Matthieu Chauvat
1. Global warming induces new constraints on forest ecosystems and requires forest management adaptation. The reduction in stand density is currently debated as a potential tool to face increasing summer drought risk by improving forest resistance to climate change-induced tree mortality. However, few studies have yet assessed the impacts of this management change on soil biodiversity. 2. We conducted a large-scale, multi-site assessment of the response of soil macro-detritivore assemblages and soil functioning to experimental...
Data from: Nutrient remobilization in tree foliage as affected by soil nutrients and leaf life spanDavid Ludovick Achat, Noémie Pousse, Manuel Nicolas & Laurent Augusto
Nutrient remobilization is a key process in nutrient conservation in plants and in nutrient cycling in ecosystems. To predict the productivity of terrestrial ecosystems, we thus need to improve our understanding of the factors that control remobilization. We studied the remobilization rates of several major nutrients (N, P, S, K, Ca, and Mg) in 102 forest ecosystems representing large environmental gradients at country scale (France). Total amounts or availability of nutrients in soils were correlated...
Data from: The indicator side of tree microhabitats: a multi-taxon approach based on bats, birds and saproxylic beetlesYoan Paillet, Frédéric Archaux, Solène Du Puy, Christophe Bouget, Vincent Boulanger, Nicolas Debaive, Olivier Gilg, Frédéric Gosselin & Eric Guilbert
1. National and international forest biodiversity assessments largely rely on indirect indicators, based on elements of forest structure that are used as surrogates for species diversity. These proxies are reputedly easier and cheaper to assess than biodiversity. Tree microhabitats – tree-borne singularities such as cavities, conks of fungi or bark characteristics – have gained attention as potential forest biodiversity indicators. However, as with most biodiversity indicators, there is a lack of scientific evidence documenting their...
