Stem and branch respiration of beech: from tree measurements to estimations at the stand level
Summary • Stem and branch respiration of 30-yr-old Fagus sylvatica trees was measured in a temperate forest for 1 yr to estimate the annual flux at the stand level. • The seasonal response ofExpand

The carbon balance of a young Beech forest
Summary 1. We present measurements of CO 2 fluxes over 2 years above and within a young Beech stand in the east of France. This site is part of the Euroflux network set up to monitor fluxes overExpand

Carbon isotope composition of current‐year shoots from Fagus sylvatica in relation to growth, respiration and use of reserves
Temporal variations in the stable carbon isotope composition (d 13 C) of leaves and current-year stems were examined in beech trees over one year. The d 13 C of both tissues were equal in the budExpand

Mixotrophy in orchids: insights from a comparative study of green individuals and nonphotosynthetic individuals of Cephalanthera damasonium.
Some green orchids obtain carbon (C) from their mycorrhizal fungi and photosynthesis. This mixotrophy may represent an evolutionary step towards mycoheterotrophic plants fully feeding on fungal C.Expand

Spatial and seasonal variations in stem respiration of beech trees (Fagus sylvatica)
Stem respiration of adult beech (Fagus sylvatica L.) trees was measured in the field in eastern France at several levels in the crown and along the stem. Strong variations in respiration ratesExpand

Differing growth responses to climatic variations and soil water deficits of Fagus sylvatica, Quercus petraea and Pinus sylvestris in a temperate forest
Abstract In addition to global warming, the frequency and the intensity of droughts will probably increase in central and southern Europe. Resulting climate changes and soil water deficits couldExpand

Comparing the intra-annual wood formation of three European species (Fagus sylvatica, Quercus petraea and Pinus sylvestris) as related to leaf phenology and non-structural carbohydrate dynamics.
Monitoring cambial phenology and intra-annual growth dynamics is a useful approach for characterizing the tree growth response to climate change. However, there have been few reports concerningExpand

Interspecific variability of stem photosynthesis among tree species.
The photosynthetic characteristics of current-year stems of six deciduous tree species, two evergreen tree species and ginkgo (Ginkgo biloba L.) were compared. Gas exchange, chlorophyllExpand

Respiration and photosynthesis characteristics of current‐year stems of Fagus sylvatica: from the seasonal pattern to an annual balance
Summary •T emperature and light responses of CO 2 efflux of Fagus sylvatica (beech) currentyear stems were measured for 1 yr to estimate their annual carbon balance. • Gas exchanges were determinedExpand

Growth duration is a better predictor of stem increment than carbon supply in a Mediterranean oak forest: implications for assessing forest productivity under climate change.
Understanding whether tree growth is limited by carbon gain (source limitation) or by the direct effect of environmental factors such as water deficit or temperature (sink limitation) is crucial forExpand
