Dynamics of multiple elements in litter decomposition under various disturbances
(2023-09-29)Both artificial disturbance and climate change regimes can strongly affect soil carbon (C) sequestration and nutrient dynamics through decomposition processes of above- and belowground residues in terrestrial ecosystems. ... -
Contributions to image-based high-throughput phenotyping in viticulture
(2023-09-29)Grapevine is a crop with significant economic importance. Unlike many other crops, grapevine is a quality crop with the focus on yield optimization instead of maximization. Regular monitoring of plant diseases and pests ... -
Structural transformation and labour market development in Sub-Saharan Africa: Evidence from Ghana and Nigeria
(2023-09-13)The thesis examines the changing economic and employment structure in Sub-Saharan Africa by focusing on Ghana and Nigeria. It is structured into an introduction and four main chapters, each answering specific research ... -
Effect of organic soil amendments on increasing soil N retention and reducing N losses from agricultural soils
(2023-09-01)In the course of my doctoral studies, I actively engaged in my advisor's research projects, which involved participating in the establishment of lysimeter experiments and conducting research on isotopes. My research findings ... -
Linking land use-land cover change with annual and perennial plant growth models for the spatio-temporal explicit simulation of ecosystem services: A case study in a savanna region of Ghana
(2023-08-30)Many West African economies have been experiencing fast growth over recent decades. At the same time, their landscapes are also experiencing one of the fastest changes in the world, and the pace has accelerated over recent ... -
Impact of dietary interventions on metabolism and the gut-brain axis in adults with metabolic syndrome traits
(2023-08-09)In recent decades, the incidence of obesity and obesity-associated comorbidities such as the metabolic syndrome has exponentially increased in both developed and developing counties. It is widely accepted that inadequate ... -
Effects of nutritive antioxidants on bone during immobility
(2023-07-27)Age and disease related inactivity in older people and inactivity during space flight and in ground-based analogs, such as 6° head-down tilt bed rest (HDBR) are associated with bone loss. This bone loss is mainly induced ... -
Adjuvant-induced alterations of cuticular waxes and their consequences for mechanisms of drought stress resistance
(2023-07-26)The most important function of the cuticular waxes is the shielding of the plant from uncontrolled water loss as well as from pathogens, UV radiation and pollutants. Penetrating agrochemicals are also effectively shielded ... -
The role of inositol pyrophosphates in the regulation of plant stress responses
(2023-07-13)Inositol polyphosphates (InsPs) have been described as important messengers in eukaryotic cells. InsPs with one or more diphospho groups are also termed inositol pyrophosphates (PP-InsPs), which gained special attention ... -
Georeferencing of Mobile Mapping Data
(2023-07-06)One of the main tasks in Engineering Geodesy is the measurement and monitoring of geometry related phenomena on local or regional scales. Examples are the generation of high-resolution 3D city models, as they are needed ... -
Assessing emerging technologies for sustainability transitions: An analysis from a technology, company and ecosystem perspective
(2023-06-29)Understanding the role of technological innovations has always been a central concern of strategic management research. Specifically, to address the current challenges of the 21st century, such as climate change ... -
Strategies for the Empirical Determination of the Stochastic Properties of Terrestrial Laser Scans
(2023-06-28)Terrestrial laser scanners (TLS) are suitable for the surface approximation of objects and their geometric changes due to the temporally and spatially high-frequent data acquisition. However, precise geodetic engineering ... -
Soil Erosion under Spatially Heterogeneous Field Conditions: Experimental Analysis and Dynamic Modeling
(2023-06-28)Soil erosion is a significant problem for most of the agroecosystems worldwide, as it is one of the primary causes of soil degradation caused by a loss of the topsoil layer. Most of the existing soil erosion models provide ... -
Conditional cash transfers, migration, and child welfare in rural El Salvador
(2023-06-23)Governments and households take various initiatives to protect and improve children’s welfare. The present research explores how effective some of those initiatives are in protecting child nutrition, increasing schooling, ... -
Improving nitrogen retention in soils treated with Pig and cattle slurry through the use of organic soil amendments
(2023-06-21)Animal slurry has recently experienced a renaissance as organic nitrogen (N) fertilizer because, on the one hand, sustainable organic farming is receiving growing attention in order to protect the environment and, on the ... -
Characterization of porcine milk exosomes from different stages of lactation
(2023-05-11)Exosomes are membranous vesicles considered major players in cell-cell communication. Milk provides adequate nutrition, transfers immunity, and promotes neonate development, and milk exosomes are suggested to have a key ... -
The effect of information provision on attitude, intention, and food choice behaviour: Four experimental studies
(2023-05-09)The agricultural and food sector in Germany is facing a number of challenges. Consumers are increasingly dissatisfied with contemporary livestock production and, in addition, livestock farming accounts for a substantial ... -
The governance of plant breeding - a social-ecological systems perspective
(2023-04-13)Climate change and social conflicts put modern agricultural systems under pressure, necessitating systemic transformations of these systems towards sustainability. At the core of these sustainability challenges to agriculture ... -
Nutrient elements in micro- to nanosized fractions: occurrence, transport, and plant uptake in agroecosystems
(2023-04-04)As phosphorus (P) is a non-substitutable nutrient for all organisms and thus pivotal in supporting crop productivity, limited and unevenly distributed phosphate rocks drive research concerns on substituted P fertilizers ... -
Drinking behaviour of llamas (Lama glama) and horses (Equus caballus) in response to saline drinking water
(2023-03-24)Saline drinking water can play an important role in the nutrition of domestic animals, either through the salinization of natural drinking water sources or the intentional application as part of rehydration therapy after ...
