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 temporal characteristics of the motion bridging effect and a connected illusion: Time-related interactions and dependencies in a two-process-model
(2025-05-22)The Motion Bridging Effect (MBE) is a visual illusion in which a motion that is not consciously visible, due to high speed, induces an illusory rotation percept in a stationary stimulus (test ring) that is presented ... -
Dendroclimatic investigation of European beech growth dynamics along a precipitation gradient in northern Germany
(2025-05-22)This thorough study of European beech (Fagus sylvatica) growth limits in Northern Germany shows the major difficulties caused by climate change and global warming. Drawing on the findings of three main chapters, we arrive ... -
Connecting the Dots: Dust Particle Tracking at Comet 67P/Churyumov-Gerasimenko
(2025-05-21)Comets and their characteristic plasma and dust tails have been intriguing people for millennia. Early theories about their nature were for example already developed by the ancient Chinese and Greek, but it was not until ... -
Preorganization within a pyrazolato-bridged bis-β-diketiminato dinickel frame as a key tool to access terminal sulfides and synergistically stabilized intermediates for acetyl-CoA synthase mimetic thioester formation
(2025-05-21)Bimetallic complexes are frequently employed in natural enzymes and in applications such as imaging, targeting, and catalysis, in order to exploit the synergy between two metal centers or to combine different functionali ... -
Responses of bird and moth communities to forest disturbance and associated management in Central European forests
(2025-05-20)Forest disturbances – such as windthrow, bark beetle and wildfire – play a key role in shaping forest ecosystems by altering forest structure, ecosystem processes and biodiversity. Central European forests are currently ... -
Investigation of Nuclear Hyperfine Coupling in H2 Heterodimers Using Rotational Spectroscopy
(2025-05-20)Rotational spectroscopy of gas phase compounds is a powerful technique for structure determination through the unique moments of inertia of a molecular system. It is sensitive angular momentum coupling; therefore, complicated ... -
Synthesis of Artificial Nucleotides for Biological Applications
(2025-05-20)This thesis explores the synthesis of nucleotides, the building blocks of DNA and RNA, two essential molecules in living cells. One project focused on developing a more effective ligand for orotidine-5’-monophosphate ... -
Effects of environmental change on grassland birds in the Central-Asian flyway through the annual cycle
(2025-05-20)Land use change is a significant driver of biodiversity loss, but its impacts have been largely studied with a particular focus on temperate regions and forest ecosystems. In this thesis, I used bird abundance, occurrence, ... -
Development of an optimization framework for complex breeding programs based on the Modular Breeding Program Simulator (MoBPS)
(2025-05-16)The aim of this thesis is to develop an optimization framework for complex breeding programs that involve numerous input parameters, auxiliary constraints, and stochastic outputs. Chapter 1 introduces the topic of stochastic ... -
Simulation-Based Data Fusion and Tracking
(2025-05-15)Autonomous systems ranging from self-driving cars and driver assistance systems, over autonomous vacuum cleaners to unmanned aerial vehicles rely on accurate perception of their surroundings to navigate and interact with ... -
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 ... -
Organic matter preservation in the presence of variable mineralogical matrices – clues to the interpretation of Precambrian biosignatures
(2025-05-09)Hydrothermal environments, such as terrestrial hot spring settings, harbored life on the early Earth. However, the scarcity of Precambrian rocks, particularly hydrothermal deposits, hinders the reconstruction of the ... -
Land Use Change in Papua, Indonesia – Assessing Deforestation Patterns and Predicting Future Hotspots of Habitat Loss to Inform Spatial Conservation Planning
(2025-05-08)New Guinea, the world’s largest tropical island, harbors some of the most biologically diverse and unique ecosystems. Despite its global ecological significance and endemic biodiversity, the region remains one of the most ... -
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 ... -
The Minimal Hypersurface Method to Obstruct Positive Scalar Curvature via the Classification of 3-Manifolds
(2025-05-05)In 1979, Schoen and Yau developed a method using descending chains of minimal hypersurfaces to obstruct psc for manifolds initially up to dimension 7. Recent results on regularity for minimal hypersurfaces extend the ... -
Communication of Colletotrichum graminicola in development and pathogenic maize interactions
(2025-05-05)Colletotrichum graminicola is a filamentous ascomycete that infects Zea mays and reduces the annual yield by 10-20 % worldwide. The fungus produces two asexual spore types, oval and falcate-shaped conidia of which the ... -
