Biomass equations for European beech (Fagus sylvatica L.) trees growing on dry sites have not been published, although such equations are needed for a proper estimation of the biomass of beech trees growing naturally at their drought limit in dry forests. We aimed to: (1) develop new allometric above-ground biomass equations for European beech tree...
Growth and survival of young European beech (Fagus sylvatica L.) is largely dependent on water availability. We quantified the influence of water stress (measured as Available Soil Water Storage Capacity or ASWSC) on vitality of young beech plants at a dry site. The study site was located in a semi-natural sessile oak (Quercus petraea (Mattuschka)...
Poor drought tolerance of European beech trees raised concerns in Europe. We hypothesized that beech could show an opposite physiological response to the same level of climatic drought with change in edaphic drought. We performed a combined analysis of δ 13 C and δ 18 O in tree rings to reveal retrospective temporal physiological responses of trees...
Norway spruce seedlings from dry lowland regions as well as from southern provenance are more drought tolerant than those from German highland provenances. Early stress detection using biomarkers indicates the later mortality dynamics of seedlings under extreme drought well. Higher drought tolerance is, however, not linked to higher resistance of a...
• Junge Fichten aus trockenen Tieflandregionen und mit südlicher Herkunft zeigen eine höhere Trockenheitstoleranz als deutsche Berglandherkünfte.
• Eine frühe Stressindikation mit Biomarkern liefert gute Hinweise auf das spätere Absterbeverhalten von Sämlingen unter extremer Trockenheit.
• Eine erhöhte Trockenstress-Toleranz der Jungpflanzen gibt a...
European beech (Fagus sylvatica L.) trees are becoming vulnerable to drought, with a warming climate. Existing studies disagree on how radial growth varies in European beech in response to droughts. We aimed to find the impact of multiple droughts on beech trees’ annual radial growth at their ecological drought limit created by soil water availabil...
The montane subtropical broad-leaved humid forests of Meghalaya (Northeast India) are highly diverse and situated at the transition zone between the Eastern Himalayas and Indo-Burma biodiversity hotspots. In this study, we have used inventory data from seedlings to canopy level to assess the impact of both biotic and abiotic disturbances on structu...
Abstract: The montane subtropical broadleaved humid forests of Meghalaya (Northeast India) are highly diverse and situated at the transition zone between the Eastern Himalayas and Indo-Burma
biodiversity hotspots. Fagaceae family are the keystone species forms an important component of these forests. These forests in Meghalaya are highly degraded a...
Biomass and leaf area equations are often required to assess or model forest productivity, carbon stocks and other ecosystem services. These factors are influenced by climate, age and stand structural attributes including stand density and tree species diversity or species composition. However, such covariates are rarely included in biomass and lea...
The Himalayas are well known for high diversity and ethnobotanical uses of the region’s medicinal plants. However, not all areas of the Himalayan regions are well studied. Studies on ethnobotanical uses of plants from the Eastern Himalayas are still lacking for many tribes. Past studies have primarily focused on listing plants’ vernacular names and...
The Himalaya is well known for high diversity and ethnobotanical uses of medicinal plants. However, not all areas of the Himalayas are well studied. In particular, studies on ethnobotanical uses of plants from the Eastern Himalayas are rare and lacking for many tribes. Past studies primarily focused on listing plants name and their traditional medi...
European beech (Fagus sylvatica L.) is the most important broad-leaved tree species in Central and Western Europe. Beech juveniles have been found to be particularly sensitive to soil drought. The growth and the survival of beech juveniles are influenced by water availability. This thesis aimed to find the effect of soil drought on tree vitality an...
