Root-restricting layers in German agricultural soils: Extent, cause and management strategies
(2020-10-21)Subsoil, i.e., soil below 30 cm depth, harbours great amounts of water and nutrients. However, physical and chemical barriers for vertical root elongation may restrict plants from accessing subsoil resources. Such ... -
Characterization of Root System Architectures from Field Root Sampling Methods
(2020-10-21)Background and objectives: The root system architecture (RSA) of a plant determines the plant’s ability to capture resources efficiently from the soil and directly linked to plant performance. The development ... -
Environment-dependent regulation of flowering time in a Barley (Hordeum vulgare L.) MAGIC population
(2020-10-21)Barley (Hordeum vulgare L.) is used as a source for food and feed and is the fourth widely cultivated cereal world-wide. Flowering time is a complex trait controlled by endogenous and environmental factors that marks ... -
Genetic and molecular analysis of drought stress adaptation in cultivated and wild barley
(2020-10-07)Drought tolerance breeding is an integral part of modern-day agriculture for sustained crop production. In this study, we employed forward and reverse genetics tools to understand and improve drought stress adaptation in ... -
Analyses on the role of non-state actors for the implementation of Sustainable Development Goals
(2020-09-17)The 2030 Agenda for Sustainable Development, adopted by United Nations (UN) Member States in September 2015, aims to solve world sensitive sustainability issues through 17 Sustainable Development Goals (SDGs) as focus ... -
Insights into the salt stress adaptation mechanisms of bread wheat genotypes using a systemic approach
(2020-09-17)Bread wheat is one of the most important crops for the human diet but the increasing soil salinization is causing yield reductions worldwide. The development of appropriate cultivars requires the elucidation of mechanisms ... -
Hygiene management in farm animal housing: Assessment of hygiene indicators and critical points in sanitation
(2020-09-04)Cleaning and disinfection together form an important aspect of hygiene management in livestock farming. The professional implementation of these hygiene measures can help to interrupt infection chains, prevent the spread ... -
Fütterungsstrategien zur Optimierung der Energie- und Nährstoffversorgung laktierender Milchkühe
(2020-09-01)Eine effiziente Nutzung von Energie und Nährstoffen spielt nicht nur vor dem Hintergrund einer bedarfsdeckenden Versorgung der Kühe, sondern auch im Hinblick auf die Umweltwirkung und die Wirtschaftlichkeit der Milchkuhhaltung ... -
Evaluating Novel Vector Control Strategies: Modeling the impact of gene editing for malaria elimination in the Democratic Republic of Congo
(2020-08-06)The tremendous burden of malaria has led to renewed efforts focusing on malaria elimi-nation in the high burden countries. However, to achieve elimination, novel tools includ-ing driving-Y gene drive mosquitoes may be ... -
Development of a one-step three dimensional approach for the phase unwrapping process in a differential InSAR stack based on Small BAseline Subset (SBAS) interferograms
(2020-08-04)Differential Interferometric Synthetic Aperture Radar (D-InSAR) is a unique technique to detect and map deformations of the Earth's surface over large temporal and spatial scales. Processing a whole stack of multitemporal ... -
Broken Roads and Broken Laws: How Infrastructure and Law Enforcement Shape Amazonian Deforestation Frontiers
(2020-06-29)Deforestation of tropical rainforests contributes significantly to global climate change and accelerated biodiversity loss. To mitigate these impacts, the goal of drastically reducing tropical deforestation has been a ... -
Ripening-delaying peptides and their applicability to steer quality development of climacteric fruits
(2020-06-24)Processes extending the shelf-life of climacteric fruits play an important role in increasing sustainability of global food supply. As consequence of uncontrolled ripening process, significant losses in quantity and quality ... -
Optimization of point grids in regional satellite gravity analysis using a Bayesian approach
(2020-03-25)The subject of this thesis is the global and regional gravity field determination from GOCE data using the short arc approach. The focus is on the extension of the regional method regarding an adaption of the model resolution ... -
Influences on the activity and lying behavior of lactating dairy cows with particular attention to lameness
(2020-03-19)Lameness, which is usually the cause of a painful claw disease, continues to be the third most common reason for culling on dairy-producing farms in Germany. Claw diseases are not only painful, affecting both health and ... -
Regulation of branched-chain amino acid metabolism in major metabolic tissues of dairy cows during late pregnancy and early lactation
(2020-04-01)For dairy cows, the transition from late pregnancy to early lactation is characterized by dramatic changes in endocrine status, nutrient utilization as well as tissue metabolism. Specific metabolic processes, e.g., in ... -
Genetic analyses of piglet survival and postnatal growth
(2020-03-20)Piglet survival determines the success of piglet production. Decreased piglet survivability raises animal welfare concerns and increasing litter sizes intensified this situation. In the recent work, the prospects to select ... -
Interactive tillage & crop residue management effects on soil properties, crop nutrient uptake & yield in different weathered soils of West Africa: measurements, modelling & scenario simulations
(2020-04-22)Sustainable crop production intensification in West Africa is hampered by constraints such as soil degradation, mainly due to excessive mining of soil nutrients, topsoil loss by surface runoff, and climatic factors like ... -
Spatio-temporal landscape transformations in Southern Chile and its implications on ecosystem services supply and beneficiaries
(2020-03-10)Human-induced global change has driven drastic modifications of ecosystems that could lead to unexpected and unprecedented transformations in the present and future decades. Current systems modifications increased the need ... -
Changes of inner teat morphology caused by the milking process and by incomplete milking during dry-off as assessed by innovative technologies
(2020-03-03)In dairy farming, the timing of the lactation cycle and the way of milk removal differ considerably from the natural conditions. Ensuring good health and wellbeing of farm animals is of great interest from both an economic ... -
