Sensitivity of planted European beech saplings to soil drought
Im Kontext des Klimawandels ist die Erforschung von möglichen Trockenheitsreaktionen der Rotbuche, insbesondere von gepflanzten Jungbäumen im Stadium der Etablierung im Waldbestand, von fundamentaler waldbaulicher Bedeutung. Im Rahmen der vorliegenden Arbeit wurden die Auswirkungen von Trockenheit …

Growth of advanced European beech trees in the transformation phase in the southern Black Forest
… crown release and its effects on the growth of European beech as a tool to aid the transformation of stands in the southern Black Forest. The research hypothesis, which spawned from this, covered the three main tree growth attributes; basal area, height and crown width, and their importance to …

Effects of climate and forest management on the water and nitrogen status of European beech regeneration and understorey vegetation
… on forests dominated by the drought susceptible European beech, especially when grown on limestone-derived soils with low water storage capacity, being common in Central and Southern Europe, are important. Moreover, climate models emphasize the significance of management practices for the …

Diversity and tree neighborhood effects on the growth dynamics of European beech and the stand seed bank in temperate broad-leaved forests of variable tree diversity
Von denjenigen aktuellen Studien, die sich mit dem Effekt der Artendiversität auf ökosystemare Funktionen beschäftigen, setzen sich nur wenige mit langfristigen Veränderungen auseinander. Vor diesem Hintergrund befasse ich mich in meiner Dissertation mit Analysen der Bodensamenbank sowie …

Canopy transpiration of beech forests in Northern Bavaria – Structure and function in pure and mixed stands with oak at colline and montane sites
… stands, and particularly of mixed stands of European beech and sessile oak. This study shows results of transpiration on different spatial-structural scales (within-tree, whole-tree and stand level) as estimated from xylem sap flow measurements, in two mixed stands in the colline-submontane …

Nutrient fluxes and soil microbial processes
… high production potentials has been a common European afforestation strategy. However, the characteristics of Norway spruce such as susceptibility to windfall, forest dieback, drought, as well as soil acidification have caused negative ecological impacts in many sites. Conversion of conifers …

Carbon and nitrogen mineralization in temperate forest soils at low temperatures
… the annual net N mineralization in a temperate European beech and Norway spruce forest soil. Gross ammonification, gross nitrification, net N and C mineralization as well as the temperature response of these processes (Q10 value) were determined at low temperatures. The influence of substrate …

Potential of above- and below-ground coarse woody debris as a carbon sink in managed and unmanaged forests
… The dominant tree species of temperate forests, European beech, Sessile oak and Norway spruce were considered. The experimental set-up permits to estimate how the C pools of a forest evolve within decades following its withdrawal from forest management. In each forest, the above-ground CWD stocks …
