Forest biodiversity in times of global environmental change: Effects of tree species identity and admixture on diversity and trophic niches of arthropods, under special consideration of the canopy and its architecture
(2024-04-26)Global climate change poses unprecedented challenges to forest ecosystems, requiring adapted management to halt loss of biodiversity and ecosystem functioning. In Central Europe, forest diebacks primarily hit profitable ... -
Modern breeding informatics approaches to optimise breeding of rhizomania resistance in sugar beet (Beta vulgaris L.) and its genomic prediction
(2024-04-26)Rhizomania, a viral disease caused by the Beet necrotic yellow vein virus (BNYVV), is considered the most destructive disease in sugar beet (Beta vulgaris L.). Since no plant protection against rhizomania is currently ... -
Schwingungsspektroskopische Untersuchungen der Wasserstoffbrückendynamik in Alkohol-α-Hydroxyester-Komplexen aus topologischer und chiraler Perspektive
(2024-04-26)The success of an organocatalytic reaction in which the bond between substrate and catalyst is non-covalent, e.g. in the form of a hydrogen bond, is determined by the topology of the hydrogen bond in the prereactive complex. ... -
Anti-aging and avalanche dynamics in ultrastable metallic glasses by X-ray photon correlation spectroscopy
(2024-04-23)Within this thesis, structural relaxation dynamics of vapour deposited as well as conventionally produced metallic glasses are studied. Vapour deposition enables to crucially tune the surface diffusion during the deposition ... -
Soil Multi-Meta-Omics: Unraveling microbial regulation at three post-genomic levels
(2024-04-19)Soil functions are key in all ecosystems globally. Specifically soils play a pivotal role in ecosystem biogeochemical cycles, sequestering but also mineralizing carbon (C), and in this context releasing nutrients from ... -
Electrochemical C–H Activation by Ruthenium and Palladium Catalysis
(2024-04-19)The emergence of direct functionalizations of C−H bonds offers efficient alternatives to traditional cross-coupling reactions, thereby saving time and costs. However, oxidative C−H activation often depends on stoichiometric ... -
Causes and consequences of female competition in redfronted lemurs (Eulemur rufifrons)
(2024-04-19)Competition among female mammals appears to be much more widespread than previously thought, and it can take on extreme forms, including eviction and even death. Nevertheless, female competition has only recently been ... -
Controlling Data Streams of IoT Devices in Smart Homes from a User Perspective
(2024-04-16)Increasingly, humans are surrounded by intelligent devices, such as smart devices, in the Internet of Things (IoT) context. These smart devices are used in various environments, such as smart environments as well as homes. ... -
Theoretical studies of metal-metal cooperativity in pyrazolate-bridged complexes
(2024-04-11)Transition metal complexes can play a variety of important roles in regard to catalysis, materials synthesis, photochemistry, and biological systems through use of their unique electronic structure, and the resulting ... -
Femtosecond spectroscopy of charge-transfer dynamics in self-assembled Pd(II) based donor-acceptor/host-guest cages and heterobinuclear alkyne-bridged W(II)-Ru(II) and W(II)-Ir(III) complexes
(2024-04-11)Using femtosecond UV/vis-pump-UV/vis-probe and -midIR-probe absorption spectroscopy the charge-transfer dynamics of self-assembling donor-acceptor Pd(II) coordination cages and heterobinuclear alkyne-bridged W(II)-Ru(II) ... -
Effects of managed forest stand composition on small mammal demography and reciprocal effects on seed predation patterns in Northern Germany
(2024-04-08)In an effort to ameliorate the impacts of climate change, forest managers in Central Europe increasingly turn to conifer species that produce higher yields and are better adapted to projected future climatic conditions. ... -
Fundamental data and conceptual framework for the exploration of geothermal resources in the Himalaya-Karakoram Orogenic belt, northern Pakistan
(2024-04-08)Northern Pakistan lies within the collision zone of the Indian and Asian plates comprising Himalaya, Kohistan, and Karakoram, with numerous hot springs associated with the Himalayan Geothermal Belt, extending 3000 km along ... -
Evaluating a Collection of Agronomic Traits to Better Understand the Importance of Epistasis and Epistasis by Environment Interaction in Maize.
(2024-04-05)Maize, a key cereal crop, stands alongside wheat and rice in global importance. Its domestication from teosinte in southern Mexico 10,000 years ago marked a turning point in human agriculture. Over the centuries, maize has ... -
Auswirkung von Bodenbearbeitungen auf den Nährstoffhaushalt von Waldböden sowie den Erfolg von Eichenkulturen
(2024-04-05)Site preparation in forests has received criticism for potentially reducing site produc-tivity due to soil compaction and nutrient losses. Nontheless, from a practical perspec-tive, site preparation is an essential factor ... -
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 ... -
Exploiting the Disulfide/Thiol Switch for Photoinduced Proton-Coupled Multielectron Transfer Reactivity
