“…It completes previous investigations that have shown a link between tree species and indirect soil-related variables, such as geology or soil types [55,60]. However, our results could be more detailed with the integration of other nutritional variables such as phosphorus, which has been determinant to species distribution in other areas [24,50]. Complementary investigations could also be carried out with direct measures of mineralization rates of N, such as incubation methods that are probably better indicators of N availability than C:N ratio.…”

“…base saturation ratio and pH) in other mountainous areas and in particular in the inner Alps [7,33,52]. In this area, it has been shown that, in contrast to the Vosges mountains, the available N and P content can be low in neutral and basic soils as well as in very acidic soils [50]. The consistency between our field results and those provided by previous field studies and experiments suggests that the different responses of tree species according to mineral soil characteristics can be extended over the Vosges Mountains context.…”

-Tree species distribution according to climatic gradients is often analysed through geographic information systems modelling whereas their nutrient requirements is mainly studied by experimentation. Using 325 forest plots, this study analysed the response of frequent tree species in the Vosges mountains, a siliceous area in northeast France, along both climate and nutrient gradients. Besides a better understanding of species behaviour, our aim was to investigate if indicator plants can be used to accurately estimate species response to ecological factors. Results showed a main effect of climate on Abies alba and Quercus petraea with a transition between both species around -20 mm of June water balance. They also showed a combined effect of climate, base saturation and nitrogen nutrition on Acer pseudoplatanus, Carpinus betulus, Fraxinus excelsior and Pinus sylvestris distribution. Nutritional and climatic variables estimated by Ellenberg indicator values or those established with the phytoecological database EcoPlant are almost as efficient as measured variables to assess tree species ecological response. natural forest / nutrient availability / climate / generalized linear models / ecological niche Résumé -Effet du climat et de la nutrition minérale sur la distribution des essences dans le massif vosgien. Le lien entre la distribution des essences forestières et les gradients climatiques est souvent analysé à partir de traitements sous système d'information géographique alors que leurs exigences nutritionnelles sont principalement déterminées par expérimentation. À partir de 325 relevés phytoécologiques forestiers, nous analysons dans ce travail la distribution de huit essences fréquentes dans le massif vosgien en prenant en compte simultanément les conditions nutritionnelles et climatiques des sites. En plus d'une meilleure connaissance de l'écologie des essences étudiées, notre objectif est de déterminer si la flore forestière peut être utilisée comme bioindicateur des conditions du milieu pour définir le comportement écologique des essences. Les résultats montrent un fort effet du climat sur Abies alba et Quercus petraea avec une transition entre les deux espèces autour de -20 mm de bilan hydrique climatique en juin. Il existe également un effet combiné du climat, du taux de saturation et de la nutrition azotée sur la distribution de Acer pseudoplatanus, Carpinus betulus, Fraxinus excelsior et Pinus sylvestris. Les variables climatiques et nutritionnelles estimées par les valeurs indicatrices d'Ellenberg ou celles calculées à l'aide de la base de données phytoécologiques EcoPlant sont presque aussi efficaces que les variables mesurées pour définir la réponse des essences aux facteurs écologiques.forêt naturelle / nutrition minérale / climat / modèles linéaires généralisés / niche écologique

“…In our study, it is intriguing that the relative importance of environmental factors should vary among neighbouring areas that differ predominantly only in their geological substrate. These differences may arise because calcareous vegetation, whilst being more nutrient-rich, varies more in quality in response to environmental variation than siliceous vegetation [74,77]. The variation in substrate in this study area has previously been shown to mediate differences in reproductive strategy, body mass [38] and horn length [37]; this study further highlights the importance of considering geological variation in studies of animal morphology, physiology and life history.…”

Environmental change and long-term body mass declines in an alpine mammal

Introduction: Climate and environmental change have driven widespread changes in body size, particularly declines, across a range of taxonomic groups in recent decades. Size declines could substantially impact on the functioning of ecosystems. To date, most studies suggest that temporal trends in size have resulted indirectly from climate change modifying resource availability and quality, affecting the ability of individuals to acquire resources and grow.

“…Grime (1979) argued that European calcareous areas are more widespread in southern latitudes and that acidic (siliceous) northern areas-under higher abiotic constraint-might have relatively depauperate species pools after Quaternary species migrations. However, the lower species richness of subalpine communities on mesic siliceous soils of the French Alps is demonstrably the result of competitive exclusion of stress-tolerant "calcareous species" by competitive "siliceous species" (Choler et al 2001;Michalet et al 2002). Conversely, the more stressful environment on dry calcareous outcrops reduces competition and enables the occurrence of a high number of stress-tolerant species (Grime 1973).…”
