Structural Complexity and Biomass of Mountain Forests in the Annapurna Region, Himalaya
(2026-01-06)Heterogeneous environmental conditions characterize mountain forests and can be highly dynamic due to climatic and socio-economic changes. Despite their importance, our understanding of forests in the Himalaya is limited, ... -
Spatial Predictions of Evapotranspiration from Tropical Landscapes Using Remote Sensing Data
(2025-12-11)Tropical forests play a crucial role in global terrestrial evapotranspiration (ET). As these forests continue to be converted to other land uses, the resulting changes in ET could have significant implications for both ... -
Micrometeorological measurements of CO2, H2O and energy exchanges between agroforestry systems and the atmosphere
(2025-12-11)Alternative land-use systems, such as agroforestry (AF), provide nature-based solutions to mitigate the impact of agriculture on climate change. Despite their multiple environmental benefits, AF systems remain poorly ... -
Green Bonding: Unlocking the Potential of Canola (Brassica napus) Protein for Sustainable Wood Composite Materials
(2025-12-11)This dissertation explores the potential of canola meal and canola protein isolate as a sustainable alternative for developing bioadhesives in the wood-based panel industry, particularly focusing on Medium Density ... -
Deriving Forest Structural and Functional Metrics from Airborne and Ground-based Mobile Laser Scanning
(2025-11-26)This study examined the application of LiDAR-based methods, specifically Airborne Laser Scanning (ALS) and ground-based Mobile Laser Scanning (MLS), to evaluate forest structural metrics and their ecological functions ... -
Polylactic acid as a binder for lignocellulosic-based insulation materials
(2025-11-26)This research explores the possible application of a renewable binder in the development of flexible insulation materials derived from lignocellulosic sources. These materials, based on lignocellulosic fibers, can be ... -
Land-use trajectories in lowland Sumatra: Impacts on leaf area index and below-canopy temperatures
(2025-11-12)Land-use change is widespread across the globe, leading to significant biodiversity loss and impairing ecosystem functions. The land-use trajectories from forest to agriculture contributes to increased surface and air ... -
Tree-water relations in pure and mixed forests: Drivers of root water uptake depth, stem water and growth dynamics
(2025-08-29)As forests face increasing pressure from climate change and growing water limitation, understanding how tree species access and use water has become crucial for predicting ecosystem resilience and guiding sustainable forest ... -
Structural finger-jointing of European beech and birch – Studies on the joining and bonding mechanisms
(2025-08-18)In the past, the finger-jointing of hardwoods was less researched and standardised compared to softwoods. This is associated with a lack of knowledge and uncertainties in the production of load-bearing hardwood engineered ... -
Impact of Jojoba wax ester synthase overexpression on drought performance and wood properties of Populus × canescens
(2025-08-13)Populus species, particularly Populus x canescens, are essential biomass trees due to their rapid growth rates. However, their susceptibility to drought due to high water consumption poses a significant challenge, especially ... -
Recording and evaluating the impacts by beavers (Castor fiber) on German forests near watercourses
(2025-08-01)Climate change is one of the most discussed environmental policy issues of recent decades. The changes that are being observed have an enormous impact on ecosystems and therefore also on their management. Many forests in ... -
Painting a bigger picture on response of European beech (Fagus sylvatica L.) to climate change – past vs. status quo
(2025-05-22)Impacts of climate change on forest ecosystems are becoming more visible than ever before. Whereas the performance of European forests is of great ecological as well as of economic importance, the term “vitality” itself ... -
The significance of chlorophyllous spores in the evolution and biogeography of ferns
(2025-05-15)Ferns, the second most diverse group of vascular plants globally, have evolved over millions of years colonizing diverse habitats across almost all continents. Ferns possess a suit of morphological and physiological traits ... -
Tree functional traits driving nitrogen cycling in pure and mixed stands of Douglas fir and European beech
(2025-05-07)Forests globally are faced with climate change-induced challenges, necessitating adaptive silvicultural strategies to prevent the decline of ecosystem functions and loss of ecosystem services. In temperate Europe, forest ... -
Terrestrial Carbon Dynamics under Land Use Transformation in Jambi, Indonesia
(2025-04-23)Tropical forests in Indonesia are rapidly being converted into agricultural systems, particularly oil palm and rubber plantations. These transformations significantly alter carbon dynamics, leading to substantial losses ... -
Effect of fragmentation and low density on gene flow and genetic diversity on two conifer species, Pinus gerardiana in Gardiz, Afghanistan, and Taxus baccata in Bavarian Forest National Park, Germany
(2025-04-14)This thesis investigates the genetic diversity, structure, and conservation needs of two coniferous species: Pinus gerardiana and Taxus baccata. Using advanced genetic markers, EST-SSRs and cpSSRs, the study reveals critical ... -
