The Effect of Root Volatiles on the Orientation Behaviour of Cockchafer Larvae in the Soil
(2011-06-24)The present study investigates the effect of root volatiles on the orientation behaviour of cockchafer larvae Melolontha hippocastani in the soil. Cockchafer larvae are known as severe pests ... -
Response of the understorey vegetation to selection cutting and clear cutting in the initial phase of Norway spruce conversion
(2010-09-02)The conversion of pure Norway spruce (Picea abies (L.) Karst.) stands into mixed stands with site adapted tree species is the main challenge of silviculture in Central Europe nowadays. ... -
Kohlenstoffvorrat, Nährstoffvorräte und Wasserdynamik nach forstlichen Eingriffen in Fichtenreinbestände
(2010-06-22)Numerous spruce stands in Germany need to be harvested now or in the foreseeable future, due to either their age, the silvicultural objective of turning from even-aged pure stands to ... -
Raumzeitliche Dynamik der Parameter des Energie-, Wasser und Spurengashaushalts nach Kleinkahlschlag
(2010-05-18)The conversion of coniferous monocultures into deciduous and mixed forest is a priority aim of silvicultural efforts in Germany. The goal is to create robust forests which are resilient ... -
Dynamik von Phosphor im Boden und von Nährstoffen im Kronenraum von Buchenwäldern unterschiedlicher Baumartendiversität
(2010-03-17)Soil nutrient pools, concentrations and turnover as well as soil nutrient inputs due to deposition and canopy exchange have been studied intensively in all kinds of forest ecosystems ... -
From arable field to forest: Long-term studies on permanent plots
(2009-01-13)Abandonment of former intensively used agricultural land is a widespread phenomenon throughout Europe since the late 1960s approximately. The absence of disturbance by agricultural land ... -
Zur Struktur und Diversität der Bodenvegetation in Laubwäldern mit unterschiedlicher Baumartenvielfalt
(2008-09-23)In this thesis, I investigate whether there are correlations between tree-layer diversity and herb-layer diversity as well as herb-layer productivity, and which environmental factors form the underlying mechanisms. ... -
The impact of canopy composition on the nutritional statusof an admixed spruce and beech forest at Solling,central Germany
(2008-04-11)It was hypothesised that in mixed spruce-beech forest ecosystems the heterogeneity in canopy composition may create different micro-sites (units) in the forest floor and the mineral soil with different ecological cha ... -
Aboveground and belowground response of European beech to drought: field studies and experiments
(2007-10-12)Global warming is predicted to shift the seasonal distribution of precipitation in Germany to reduced rainfall in summer and enhanced precipitation in winter. The estimated rates of future climatic change are expected to ... -
Zur zukünftigen Rolle der Buche (Fagus sylvatica L.) in der natürlichen Vegetation - waldökologische Untersuchungen zur Buchen-Naturverjüngung an der östlichen Buchenwald-Verbreitungsgrenze
(2007-01-29)The knowledge about the distribution boundary of European beech forests (Fagus sylvatica L.) in the northeastern part of Central Europe (North-East Germany and Poland) is still ... -
Auswirkungen von Ökosystemmanipulationen auf Vorratsänderung und Freisetzung von C- und N- Verbindungen
(2006-10-12)The organic material (OM) in soil plays an essential role as well in the structure as in the function of terrestrial ecosystems. The amount and distribution of OM in soil is characteristic ... -
Soil chemical and biological changes through the N2 fixation of black locust (Robinia pseudoacacia L.) - A contribution to the research of tree neophytes
(2005-09-21)Worldwide the land area covered by stands with the neophytic tree legume Robinia pseudoacacia L. (black locust) has expanded to about 3 Mio. ha and is predicted to extend further in ... -
Verjüngung der Stieleiche (Quercus robur L.) in oberrheinischen Auenwäldern
(2004-11-04)The work investigates silvicultural methods to regenerate pedunculate oak (Quercus robur L.) naturally and artificially in floodplain forests of the state Rhineland-Palatinate (Germany). ... -
Mechanisms of Carbon and Nitrogen transformations in Forest floors of Beech-, Spruce- and Mixed Beech-Spruce Stands
(2004-02-27)The mechanisms of carbon and nitrogen transformation in forest ecosystems are important for the element cycling in forest ecosystems. Most forests in Germany have moder and mor humus forms ... -
Anpassung antioxidativer Systeme an Licht und Temperatur:
(2001-05-21)Unfavourable environmental conditions can cause oxidative stress in aerobic organisms. The acclimation of the antioxidative system in beech (Fagus sylvatica) and spotted nettle (Coleus ...
