Following a full mast production in autumn 1995 in the old growth beech forest of la Tillaie, France, cupules, live and dead yearling seedlings were counted in September 1996 in 40 plots, embracing a wide range of ecological conditions. The influence of geomorphology and forest stage on mast production and on seedling establishment and survival was studied. Maximum seedling abundance did not oc...
In order to evaluate the effects of forest road on vegetation and some soil properties was selected a road with the length of 400 m. Type and number of regeneration species of trees and shrubs in plot area of 100 m2 and type and cover percentage of herbaceous species using minimal area method were recorded in plot area of 64 m2 and herbaceous species was classified into two groups using Two-W...
In order to comprehend detailed forest resources, the use of high spatial resolution data is expected. However, the efficeint forest cover type classification method of high spatial resolution data is not cleared yet. So, this study discussed the potential of the forest cover type classification such as classification of coniferous forest, broadleaved forest, and mixed forest, and tree speices ...
Background Forest soils are considered sinks for atmospheric C. Many studies revealed that tree species and their mycorrhizal association affect forest floor topsoil organic C (OC) total N, while the knowledge of effect on subsoil OC N is still scarce. Aims We aimed to identify (1) effects floor, (0–30 cm) (30–80 stocks vertical distribution (2) drivers soil distribution. Methods sampled under ...
Adaptations of Abies nordmanniana, Picea orientalis, Pinus sylvestris, Fagus and Carpinus betulus to the abiotic environmental conditions study area largely determined their predicted distribution in Caucasus. The ecological niches species mostly coincided two analyzed complex factors (characteristics water regime topographic parameters). humidity factor was main determining potential forest-fo...
Phytocoenotic behaviour of 14 nemoral or boreal-nemoral vascular plant species is analyzed in the middle- and southern-taiga subzones comparison with that broadleaved-forest zone, based upon set 1669 relevés made European Russia 1996–2018. The are mainly represented by shadow mesoeutrophic plants from “corteges” Tilia cordata s. l. Fagus sylvatica. more light-demanding Quercus robur “cortege”, ...
Forest mycorrhizal type mediates nutrient dynamics, which in turn can influence forest community structure and processes. Using forest inventory data, we explored how dominant forest tree mycorrhizal type affects understory plant invasions with consideration of forest structure and soil properties. We found that arbuscular mycorrhizal (AM) dominant forests, which are characterised by thin fores...
European beech (Fagus sylvatica L., hereafter beech), one of the major native tree species in Europe, is known to be drought sensitive. Thus, the identification of critical thresholds of drought impact intensity and duration are of high interest for assessing the adaptive potential of European beech to climate change in its native range. In a common garden experiment with one-year-old seedlings...
PREMISE OF THE STUDY Gravitropic movements are unexpected mechanical processes that could disturb tree design allometries derived from the physics of nonliving bodies. We investigated whether the scaling law of gravitropic performance (power of -2 of stem diameter) derived from integrative biomechanical modeling is disturbed by ontogeny or environment, then discuss the silvicultural and dendroe...
