Aim: Tree crowns determine light interception, carbon and water exchange. Thus, understanding the factors causing tree crown allometry to vary at the tree and stand level matters greatly for the development of future vegetation modelling and for the calibration of remote sensing products. Nevertheless, we know little about large-scale variation and...
The olive tree (Olea europaea L. subsp. europaea var. europaea) is currently one of the most widely cultivated temperate fruit trees in the world. It is characterised by a large genetic diversity, as well as a large variation in phenotypic traits. Across the Mediterranean Basin, the nuclear genetic diversity of olive is organized into three main gr...
As demand for pepper is rising to unprecedented levels, gaps in our knowledge are underlined by our inability to reliably distinguish the different species, in particular in the south-western Indian Ocean; this hampers the possibility of developing their economic potential and protect them efficiently. The aim of this study was to characterise two ...
Leaf biochemical and structural traits are vegetation characteristics related to various physiological processes. Taking advantage of the physical relationship between optical properties and leaf biochemistry, field-based spectroscopy has allowed for the rapid estimation of leaf biochemical constituents and repeated non-destructive measurements thr...
Les enfants élaborent des représentations de la science et des scientifiques dès les premières années de l'école primaire. À ce niveau scolaire, les élèves qui participent à des activités expérimentales, encadrées par des enseignants et des scientifiques, bénéficient d'un autre regard sur la recherche et se projettent davantage dans les pratiques s...
The physiological stage of mango maturity at harvest affects fruit quality at the time it is commercialized. The objective assessment of the mango maturity stage at harvest remains a challenge because of the multiple interactions between the visual aspect, the physicochemical composition, and the morphology of the fruit. This study aims to quantify...
Drought‐induced xylem embolism is considered to be one of the main factors driving mortality in woody plants worldwide. Although several structure–functional mechanisms have been tested to understand the anatomical determinants of embolism resistance, there is a need to study this topic by integrating anatomical data for many species. We combined o...
Increasing the cultivated diversity has been identified as a major leverage for the agroecological transition as it can help improve the resilience of low input cropping systems. For wheat, which is the most cultivated crop worldwide in terms of harvested area, the use of cultivar mixtures is spreading in several countries, but studies have seldom ...
Trees can modify their wood structure in response to changes in mechanical, hydraulic and storage demands during their life-cycles. Thus, examining radial variations in wood traits is important to expand our knowledge of tree functioning and species ecological strategies. Yet, several aspects of radial changes in wood functional traits are still po...
Ambrosia trifida L. (giant ragweed, Asteraceae) is native to the North American continent and was introduced into Europe and Asia at the end of the 19th century. In its native range, this tall annual species is common in riparian and ruderal habitats and is also a major weed in annual cropping systems. For nearly a century, A. trifida has also been...
