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 ... -
On the ground and above: Forest Composition Effects on Terrestrial and Arboreal Small Mammals and their Consequences for Seed Dynamics
(2025-04-10)1- Forest admixtures and non-native tree species have been increasingly employed in forestry practices as they have the potential to mitigate climate change impacts, enhance biodiversity and yield a greater economic ... -
Integrating Deep Learning Techniques into Trees Outside Forests (TOF) Monitoring by High Resolution Satellite Imagery
(2025-04-08)Trees outside forests (TOF) provide essential ecosystem services and livelihood benefits across diverse landscapes. They are also recognized as important carbon sinks, playing a crucial role in climate change mitigation ... -
Untersuchung von Parasiten in Wildgehegen: Einsatz innovativer Technologien und biologischer Antagonisten
(2025-03-27)Objectives Wild animals kept in enclosures are exposed to an increased risk of parasite infections due to their limited range of movement and the sometimes high animal density and associated heavy soiling of the enclosures. ... -
Multifaceted Diversity in Forest Ecosystems Worldwide
(2025-02-25)Earth’s biodiversity faces numerous threats that endanger the delicate balance of ecosystems, highlighting the urgent need for integrated conservation strategies to preserve biodiversity. Forests in particular are critical ... -
Landscape Moderation of Ecological Patterns and Processes
(2025-02-25)This dissertation studies landscape moderation of ecological patterns and processes by employing different modeling approaches to investigate how landscape patterns influence ecological processes and, reversely, how ... -
Poplar Responses to Nutrient Deficiency and Drought as Affected by Different Ectomycorrhizal Fungal Species
(2025-02-14)Nutrient imbalances and drought are challenges the world’s forests are currently facing due to massively changing environmental conditions. In European forests, phosphorus (P) nutrition is declining due to increasing ... -
Entwicklung eines Standards zu Zugriff auf und Nutzung von digitalen Prozessdaten innerhalb der technischen Produktion von Rundholz am Beispiel der motormanuellen Holzernte
(2024-11-22)Summary Introduction: As part of the secondary or technical production of round wood, data is increasingly being collected to obtain further information. It has become established to process the operational data of ... -
Transaktionskosten bei der Bewirtschaftung von kleinerem Privatwald in Deutschland
(2024-11-14)Despite previous efforts, the problem of forest underutilization in smaller German private forests remains unsolved. With the growing impact of climate change and the legal obligation of forest owners to manage forests ... -
Restoration of coniferous monocultures towards mixed broad-leaved forests in Central Europe – Patterns and processes of stand and vegetation diversification
(2024-11-05)Globally, forests provide essential ecosystem services to society, but their functionality is increasingly impaired by abiotic and biotic disturbances that are expected to further increase with predicted climate change. ... -
Genotype effect on Norway spruce (Picea abies) mycobiome and resistance against Heterobasidion parviporum under abiotic stress
(2024-11-05)Norway spruce (Picea abies L. Karst.) holds considerable economic importance as a tree species in Europe. However, it faces significant vulnerability to attacks from the Heterobasidion annosum species complex, resulting ... -
Mycorrhizal mediation of nutrient distribution and stress responses in beech and conifer mixtures
(2024-10-14)With global warming, drought is a rising concern for forests worldwide. In Central Europe, drought has caused severe diebacks of Norway spruce (Picea abies), the most common and economically relevant tree species. ... -
