The Lower Cretaceous is a period during which several groups of embryophytes still present in current ecosystems appear in the fossil record and/or diversify, such as Pinaceae, Cupressaceae and angiosperms. At the beginning of the Lower Cretaceous, gymnosperms still constituted the main component of arborescent strata (Gynkgoales, Cycadales). The P...
Dossier comportant une version de SamsaraLightLoader - simulateur de bilan radiatif pour peuplements réguliers et peuplements mélangés à couvert continu, la fonction CapuLight permettant de lancer les simulations et d'obtenir des cartes de lumière, un manuel d'utilisation de ce logiciel et un exemple de carte de lumière créé automatiquement par Cap...
Pour régénérer une (ou plusieurs) essence(s) feuillue(s), éventuellement en mélange avec des résineux, à partir d’une mise à blanc, nous proposons ici la technique de plantation en cellules denses localisées, avec des recommandations issues de notre expérience. Cette méthode permet d’optimiser la qualité des arbres plantés, est moins coûteuse que l...
peer reviewed / Abstract. With a changing climate, it is becoming increasingly critical to understand vegetation responses to limiting environmental factors. Here, we investigate the spatial and temporal patterns of light and water limitation on photosynthesis using an observational framework. Our study is unique in characterizing the nonlinear rel...
peer reviewed / European lowland beech stands are under pressure by current climate change and increased drought spells. Climate sensitivity of trees is most commonly studied by examining tree-ring width records and wood density-based time series, yet the potential of the latter is underexplored for hardwoods and beech (Fagus sylvatica L.) in parti...
peer reviewed / Understanding the role of nutrients in the alleviation of salt stress effects and the unrevealed significance of root system architecture for plant adaptation is one of the major research areas in the current context of agriculture. Root anatomy is also a valuable parameter to be considered in understanding how the root system count...
peer reviewed / Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climate change. Yet no large-scale assessments of threat management strategies exist. Applying a structured participatory approach, we demonstrate that existing conservation efforts are insufficient in a changing world, estimating that 65% (at best 3...
Background: Natural forest regeneration helps restore multiple ecosystem functions, including carbon stocks. A better understanding of natural forest regeneration among fallow ages could help develop more effective restoration strategies in tropical forests. Aims: This study aims to examine variation and relationships in structural and diversity at...
peer reviewed / Salt stress impacts phosphorus (P) bioavailability, mobility, and its uptake by plants. Since P is involved in many key processes in plants, salinity and P deficiency could significantly cause serious damage to photosynthesis, the most essential physiological process for the growth and development of all green plants. Different appr...
