Availability of aerial and soil resources in oak forests is likely to change in the near future: wood harvest will increase to fulfill biomass demand and atmospheric N deposition is still high. Accordingly, oak seedlings will benefit from a larger availability of both incoming irradiance and soil inorganic N (Ni) amounts. Such changes may also favo...
Ecological theories on species occurrence and interactions between them deeply rely on resources availability. Grasses are known for their ability to preempt belowground resources, especially nitrogen to the detriment of tree seedlings. Objective of the study was to determine how combination in contrasted soil inorganic nitrogen x light availabilit...

The study tested the hypothesis that future changes in the composition of tree communities, as predicted by species distribution models, could already be apparent in the current regeneration patterns of three pine species (Pinus pinaster, P. nigra and P. sylvestris)inhabiting the central-eastern mountains of Spain. We carried out both an observatio...
New adaptation and mitigation strategies are needed to manage temperate forests in the context of climate change with more frequent droughts. Thinning intensification has been proposed as an adaptation strategy to improve forest resistance to drought. Partial cutting of forest stands by thinning operations mimics the natural disturbance by treefall...
Plant competition and deer browsing are two main factors which limit tree recruitment. We examined natural tree-recruitment processes under continuous-tree-cover management. Changes in plant communities and tree regeneration were monitored over an eight-year period at two different sites in a temperate hardwood forest in the North-East of France. W...
Ecologists have long argued about the modification of plant competition along abiotic gradients, and particularly along resource gradients. Through simulations, we evaluated the impact of bramble defoliation by roe deer on the response of oak seedlings to bramble presence along two resource gradients. We set up a controlled experiment crossing: (i)...
Les savoirs des communautés rurales relatifs à l'adaptation des pratiques agricoles et pastorales aux difficultés et aux aléas du climat leurs ont permis d'améliorer leur résilience dans un environnement naturel vulnérable et contraignant en assurant la production alimentaire et la provision de biens et services nécessaires à la production de la co...
Trees outside forests (ToF) is often a misunderstood category. This is the case in Brazil as shown by the lack of data on ToF reported until now by the country. In this article, ToF are understood in relation to the FAO definition of forest because it is the definition used in Brazil for the National Forest Inventory. I provide a definition of ToF,...
Light under tree canopy cover is essential for the study and understanding of plant diversity, regeneration, plant growth and many other forest ecosystem processes; however, quantifying light is difficult and requires specialized equipment. That is why proxies or models predicting light availability can help scientists to obtain estimates of transm...
The importance of environmental stochasticity for tropical tree dynamics has been recently stressed by several studies. This has spurred the development of a 'time-averaged neutral model' of community dynamics by Kalyuzhny and colleagues that extends the neutral model by incorporating environmental stochasticity. We here show that this framework ca...
