Natürliche Waldentwicklung unter dem Einfluss des Borkenkäfers im Nationalpark Berchtesgaden
(2016-06-24)Disturbances are an integral part of forest ecosystems. Integrating single-tree dynamics to large-scale disturbances as windthrows, fire or insect calamities, disturbances influence natural species composition and regeneration ... -
New adaptive plot designs for sampling rare and clustered populations
(2012-02-07)In this methodological study, three new and more practical adaptive plot designs (I, II and III) are introduced with an overall objective to improve the efficiency of sampling rare and ... -
Nutrient response efficiency, tree-microbe competition for nutrients and tree neighborhood dynamics in a mixed-species temperate deciduous forest in central Germany
(2015-10-23)In most Central European countries, less than one percent of the remaining broadleaved forest is undisturbed and temperate forests face challenges such as species invasion, climate change and increased nitrogen deposition. ... -
Ökonomische Analyse forstlicher Bestandesbehandlung
(2020-11-18)The economic analysis of forest stand management serves the understanding of an efficient timber production in a world of scarce resources. Following Möhring (2009), the present study aims to build a bridge between economic ... -
Picea abies and climate change – does increasing thinning intensity prevent drought stress?
(2017-10-11)The predicted increase in frequency of intense and prolonged drought events challenges forest management. Centuries of forest management has led to Norway spruce (Picea abies [L.] Karst.) monocultures outside its natural ... -
Process optimization of thermal modification of Chilean Eucalyptus nitens plantation wood
(2019-02-22)Eucalyptus nitens is one of the most important fast growing plantation species in Chile. Currently it is mostly used for pulp and paper, but in recent years there has been a growing market for solid wood products to increase ... -
Quantifizierung der Feinwurzeln von Bäumen durch elektrische Verfahren
(2015-04-23)The quantification especially of fine roots of trees creates some difficulty because, contrary to the aboveground parts of the tree, roots are not readily visible. In recent years electrical methods have been developed for ... -
Quantifying stand structure and structural complexity along a management gradient in temperate forests
(2020-10-01)The structure and structural complexity of forests influence many important characteristics of forest ecosystems, as well as their functions and services, such as ecosystem stability, maintenance of biodiversity and carbon ... -
Quantifying the impact of forest management intensity and tree species diversity on individual tree shape and three-dimensional stand structure
(2020-11-04)The three-dimensional distribution of trees and their crowns is an essential characteristic of forest ecosystems that is directly related to several ecosystem functions and services. Silvicultural interventions modify the ... -
Quantifying three-dimensional stand structure and its relationship with forest management and microclimate in temperate forest ecosystems
(2018-02-01)Summary Forest management modifies the spatial structure of forest ecosystems, which is considered to be relevant for habitat availability and biodiversity as well as several ecosystem processes and functions. Contrary ... -
Quantifying three-dimensional stand structure of European beech forests along a management gradient
(2022-04-26)Forest structure is of functional importance for ecosystem stability and resilience, as well as for numerous other ecosystem functions and services. In this context, a high structural complexity can have a positive effect ... -
Reaktion von Waldbeständen am Rande der südlichen Taiga auf Klimafaktoren, natürliche und waldbauliche Störungen
(2017-11-30)The northern Mongolian mountain forest steppe, the transition zone between taiga and open steppe, is rich in plant and animal life. It is the most productive region in the country in terms of agriculture and, as a result, ... -
Sensitivity of phyto-geocentric site productivity models to spatial extent and climate data aggregation
(2024-02-20)The impact of climate warming on forestry in Germany and Europe has become more and more visible in recent years and decades. This has lead to an increased demand for predictions on the development of forest stands with ... -
Surveillance of tick-parasitized voles, mice and roe deer in Germany: Arboviral infection rates in relation to population densities and host characteristics
(2010-11-17)This dissertation is focussed on the ecology of tick-borne encephalitis (TBE), an infectious disease of major medical significance. The thesis is organised as a series of 9 self-contained ... -
The effect of neighborhood identity on seasonal tree growth responses and ecophysiological characteristics of European beech (Fagus sylvatica L.)
(2020-01-17)Climate change related rise in mean surface (air) temperature, altered intra-annual thermal and precipitation regimes as well as an expected increase of extreme weather events which are also prognosticated for large parts ... -
Threatened tree species across conservation zones in a nature reserve of North-Western Vietnam
(2017-03-21)The high diversity of tree species in tropical forests is driven by a large proportion of rare species. Rare species are vulnerable and threatened to extirpation and extinction when their habitats are destroyed. This study ... -
Tree transpiration inforest plantations: Effects of species, seasonality and diversity (Panama)
(2010-06-25)Forests serve many benefits worldwide such as providing renewable raw materials and energy, maintaining biodiversity and protecting land and water resources. However, they are threatened ... -
Tree water uptake partitioning and water use rates in a temperate mixed forest
(2014-01-09)Little information is available on the relationship between tree species diversity and forest stand water use although water availability is considered a major control of productivity in forests of central Europe and other ... -
Vergleich von stillgelegten und bewirtschafteten Wäldern anhand von zwei Fallbeispielen in Brandenburg
(2024-04-02)Forests can provide a wide range of ecosystem services. However, not all ecosystem services can be maximized at the same time, which can lead to conflicting objectives. For example, objectives range from maximizing the ... -
Vorschläge zur Optimierung/Verbesserung der genetischen Qualität von Saatgut aus Erntebeständen bei den Eichenarten (Quercus robur L. & Quercus petraea [Matt.] Lieb.)
(2022-10-27)Climate models predict drier and warmer summer months and increasingly frequent drought events. As a more climate-resilient tree species, oak will therefore become much more important than other deciduous trees and even ...
