Evolution of polyploidy and apomixis in the pantropically distributed and species-rich genus Zanthoxylum (Rutaceae)
(2025-04-22)The proto-Rutaceae group includes genera with significant economic and evolutionary importance, yet their phylogenetic relationships and evolutionary mechanisms remain incompletely understood. This thesis focuses on the ... -
Understanding the Effective Number of Independent Chromosome Segments as a Tuning Parameter for Genomic Prediction
(2025-04-16)The effective number of independently segregating chromosome segments (𝑀𝑒) is a key parameter in animal selection. Its relevance lies within the methods to obtain the accuracy of genomic prediction. However, there is ... -
Housing pigs with undocked tails: methods for the early detection and prevention of tail biting
(2025-04-15)The occurrence of tail biting is a widespread problem in global pig farming. Painful biting incidents lead to a significant impairment of animal health, animal welfare and the performance of pigs in various production ... -
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 ... -
Small-scale dynamics and large-scale stability of the outer solar atmosphere
(2025-04-14)The Sun has long been utilized as an observatory for gaining a better understanding of high-energy plasma physics. With the advent of the space age and the continual improvement of Sun-observing instruments, physicists ... -
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 ... -
Enantioselective Electrochemical C–H Activation with Cobalt, Nickel, and Iron
(2025-04-04)The enantioselective functionalization of otherwise inert C–H bonds to assemble chiral molecules has become an increasingly powerful tool in molecular synthesis. In spite of significant advances in this domain, the ... -
Computational Complexity Meets Statistical Efficiency: From Change Point Estimation to Monotonicity Testing
(2025-04-04)In the Information Age, statistical efficiency and computational tractability have become equally important. In this dissertation, we propose two novel statistical procedures: the Fast and Optimal Monotonicity Test (FOMT) ... -
Role of root exudates as signals in the interaction of Brassica napus L. roots with Verticillium longisporum in the soil
(2025-04-03)Verticillium longisporum is a soil-borne pathogen that primarily infects brassicaceous plants, including oilseed rape, a major global source of vegetable oil and oil extraction meal. V. longisporum causes stem striping ... -
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. ... -
Klimarisikomanagement - Akzeptanz und Potential satellitenbasierter Indexversicherungen in Deutschland
(2025-03-27)Although drought is the most relevant production risk for farmers in Germany, the demand for weather index insurance remains very low. Given that basis risk is known to be one of the main inhibiting factors of farmers’ ... -
Observation of four top quarks production and EFT interpretations in the multi-lepton final state with the ATLAS Experiment
(2025-03-27)The Standard Model has been remarkably successful in describing fundamental particles and their interactions. However its incompleteness makes the search for physics beyond the Standard Model one of the most important ... -
Social evaluation and decision-making in nonhuman primates
(2025-03-25)One of the challenges of living in a group is constantly having to decide when, how, and whom to interact with among several conspecifics in plenty of different contexts. For optimal decision-making, social animals can ... -
Computational studies and embedding strategies for the characterisation of a novel covalent bond in proteins
(2025-03-25)This work offers a comprehensive study on the bond properties of a noval covalent bond between three electronegative atoms nitrogen, oxygen and sulfur (NOS), which is found in proteins as crosslink between lysine and ... -
Lying with Deceptive Implicatures: The Roles of Commitment, Culture, and Partisan Bias
(2025-03-25)The aim of the present work is to advance our understanding of how ordinary speakers use the term lying to categorize deceptive behaviours they inevitably encounter in their everyday lives. Although a firm grasp of how ... -
