“…As far as litter is concerned, the decrease in thickness is somewhat expected as gap creation reduced the number of trees in the surroundings and leaded to a smaller annual litter fall in the gaps. Such result has also been recorded in other studies [2,54]. The observed lack of change in Of thickness seems to be contradictory with the study of Arpin et al [2] who observed thinner Of horizons in clearings.…”

“…It is known that those social light-requiring species, with greater plant height and quick expansion, are able to overgrow, outshade and outcompete smaller species when the conditions, such as light, are favourable [17,30]. The development of such competitive species, may then characterize the plant community in gaps [2] and reduce the plant diversity by preventing establishment or growth of other species.…”

“…On the hypothesis of a higher species richness in the gaps compare to the species richness under undisturbed forest, the study addressed the following questions: (1) is there any indicator species of forest and gaps, (2) are there some changes of the resource requirements of the plant community, (3) does the functional diversity (proportion of species traits) differ between forest and gaps?…”

-Windstorms are major disturbance factors in temperate forests of Western Europe. With climatic changes those events are likely to become more frequent. The study of their impacts on plant communities is essential. Therefore our objective was to evaluate the differences of the plant community after the 1999 windstorm that blew down approximately 968 000 ha across France. This study took place in the North Vosges (36 800 ha destroyed). The differences in species diversity, resource requirements and functional plant traits were analysed, with floristic surveys, between undisturbed forest (10 plots) and gaps ranging from 250 m 2 and 1.8 ha (65 plots). The results showed a higher plant diversity in the gaps. This increase was mainly due to the presence of more light-requiring forest species and more species with high dispersal abilities (anemochorous or long-term persistent seedbank species). On the contrary, species with greater competitive abilities increased their cover and decreased the diversity. The other resource requirements were not modified in the gaps. This short-term study showed that functional traits and their interactions play a major role to determine the species composition in gaps, especially compared to the species requirements for the resources, except light. forest gaps / vegetation changes / species diversity / functional traits / Ellenberg indicator valuesRésumé -Les trouées favorisent la diversité végétale en hêtraie (Luzulo-Fagetum), dans les Vosges du Nord, France. Les tempêtes sont un facteur perturbateur principal des forêts tempérées d'Europe de l'Ouest. Suite aux changements climatiques, celles-ci deviennent de plus en plus fréquentes. Il apparaît essentiel de mieux comprendre leurs impacts sur les communautés végétales. Notre objectif était donc d'étudier les variations de la communauté végétale, en terme de diversité spécifique, d'exigences écologiques et de traits de vie des espèces. Cette étude fait suite à la tempête de 1999 ayant ravagé la France et provoqué des chablis massifs de l'ordre de 968 000 ha, dont 36 800 ha dans les Vosges du Nord. Des relevés de végétation ont été réalisés, dans une hêtraie des Vosges du Nord, dans 65 placettes au sein de trouées de 250 m 2 à 1,8 ha et dans 10 placettes sous forêt non perturbée. Les résultats ont mis en évidence une plus grande diversité végétale au sein des trouées. Cette augmentation résultait essentiellement d'une augmentation du nombre d'espèces forestières héliophiles (telles que les espèces de lisières) et d'espèces à grande capacité de dissémination (espèces anemochores ou à banque de graines permanente). Par contre, le recouvrement des espèces à plus grande capacité compétitrice augmente, ce qui provoque une diminution de la diversité. Les autres caractéristiques écologiques de la communauté végétale ont été peu modifiées par l'apparition des trouées. Cette étude à court terme a mis en évidence que la composition spécifique des trouées résulte essentiellement des traits fonctionnels et leur interaction, surtout en comp...

“…young individuals still growing in height) on soil-dwelling earthworms, demonstrated by Ponge and Delhaye [36] on the La Tillaie site, thus needs to be reconsidered, taking into account small-scale changes occurring beneath an individual tree. The improvement of soil biological activity which occurs during maturity then senescence of forest ecosystems [1,7,36] does not hold for the small area (less than 1 m diameter) surrounding the trunk.…”

A non-random sampling design allowed to distinguish within a virgin beech ecosystem two main components of humus profile heterogeneity. The stratification of the profile into horizons reflects changes in the composition of the soil/litter matrix occurring under the influence of the anisotropic deposition of leaf and wood litter and the stratified occurrence of soil organisms (roots, microbes, animals). The horizontal heterogeneity is mainly influenced by changes in vegetation, in particular the decreasing influence of beech (and the increasing influence of ground vegetation) when passing from the tree trunk base, where the influence of the tree reaches a maximum, to the centre of adjacent gaps where the influence of beech is replaced by that of another vegetation. The use of multivariate methods, used for description rather than for modelling, is suggested to be the best procedure for understanding patterns underlying heterogeneity without a priori assumptions.
