Influence of endocrine status on small ruminant sperm freezing response: Use of wild and domestic ruminants as an experimental model
Martínez-Fresneda Muñoz, Lucía (2019-11-22)Assisted reproductive technology improves livestock management and allows the storage of valuable genetic material of wild and domestic species in germplasm banks. Nevertheless, the use of frozen-thawed sperm for artificial ... -
Analysis and mitigation of site-dependent effects in static and kinematic GNSS applications
Zimmermann, Florian (2019-10-08)Satellitensignale unterliegen auf ihrem Weg von der Satelliten- zur Empfangsantenne einer Vielzahl an Einflüssen die zu Abweichungen führen. Heutzutage stellen in vielen Anwendungsbereichen insbesondere die stationsspezifischen ... -
Phosphorus forms in fertilized arable soil profiles and related 33P uptake
Koch, Maximilian (2019-09-13)Arable soils usually store several thousand kg phosphorus (P) per ha, thus far exceeding the recommended P fertilizer dose to sustain crop yields. However, the soil profile is frequently not considered in fertilizer ... -
Food waste reduction concepts for stakeholders in the food supply chain and auxiliary organizations
Strotmann, Christina (2019-09-10)The objective of this thesis was to develop concepts to support the reduction of food waste in the food sector. The concepts are targeted to private companies, such as manufacturing businesses, retailers, and large-scale ... -
Genetic mapping of quantitative trait loci associated with arsenic tolerance and accumulation in rice (Oryza sativa L.)
Murugaiyan, Varunseelan (2019-09-04)<strong>Genetische Kartierung von quantitativen Trait Loci im Zusammenhang mit Arsentoleranz und Akkumulation im Reis (<i>Oryza sativa</i> L.)</strong><br /> Reis (<em>Oryza sativa.</em> L) ist eines der wichtigsten ... -
Partitioning Water Vapor Fluxes by the Use of Their Water Stable Isotopologues: From the Lab to the Field
Quade, Maria Elisabeth (2019-09-04)Water stable isotopes are powerful tracers for partitioning of the terrestrial ecosystem water vapor fluxes into process-based components, i.e. evapotranspiration (<em>ET</em>) into soil evaporation (<em>E</em>) and plant ... -
Untersuchungen zur Wirkung metallischer Nanopartikel auf Pflanzen
Fellmann, Sebastian (2019-08-27)Die zunehmende Verwendung von Nanopartikeln (Np) in Konsumgütern und industriellen Anwendungen löst im Hinblick auf deren mögliche Freisetzung in der Umwelt und die damit verbundenen Auswirkungen auf Ökosysteme und Organismen ... -
Nitrogen sequestration in paddy and non-paddy soils formed from different parent materials
Houtermans, Miriam (2019-08-19)Paddy soils exhibit low nitrogen (N) use efficiency. Prior research in this field suggested that paddy soils may sequester significant amounts of N in aged amino acids, microbial residues, or even in pyrogenic N. The ... -
Demand for organic food in Switzerland
Götze, Franziska (2019-08-20)The aim of this dissertation is to better understand the functioning of the organic food market in Switzerland. Over the last three decades the market for organic food in Switzerland has developed positively and continues ... -
Spatial competition of learning agents in agricultural procurement markets
Khalili, Hamed (2019-07-15)Spatially dispersed farmers supply raw milk as the primary input to a small number of large dairy-processing firms. The spatial competition of processing firms has short- to long-term repercussions on farm and processor ... -
Challenges and opportunities of using ecological and remote sensing variables for crop pest and disease mapping
Kyalo, Richard (2019-07-15)Crop pest and diseases are responsible for major economic losses in the agricultural systems in Africa resulting in food insecurity. Potential yield losses for major crops across Africa are mainly caused by pests and ... -
Modeling the impact of biopores in the soil on root growth and root water uptake
Landl, Magdalena (2019-06-19)<strong>Background and Motivation:</strong> Biopores are tubular shaped cavities in the soil formed by biological activity that enable plant roots to reach water and nutrient reservoirs at greater depths. Especially during ... -
Visual Odometry and Sparse Scene Reconstruction for UAVs with a Multi-Fisheye Camera System
Schneider, Johannes (2019-06-13)Autonomously operating UAVs demand a fast localization for navigation, to actively explore unknown areas and to create maps. For pose estimation, many UAV systems make use of a combination of GPS receivers and inertial ... -
Boundary work and agricultural innovation systems: Stakeholder interaction and learning using an example of push-pull technology in Ethiopia
Nyang'au, Isaac Mbeche (2019-06-17)Maize is an important cereal crop for food security in Ethiopia. However, its productivity is low with average grain yields of less than 1 ton/ha which is below its potential of over 4 ton/ha. This is attributed to a variety ... -
Rice yield gaps in West Africa
Niang, Abibou (2019-05-15)Rice is a staple food for many countries in Africa but the production has never satisfied the demand which largely depends on imports. Therefore, more efforts are needed for raising yield in order to reduce the gap between ... -
Studies on nematode factors activating the plant immune system
Mendy, Badou (2019-05-15)Plant-parasitic nematodes are destructive pests causing crop losses accounting for billions of dollars annually. To defend against invading pathogens plants rely on innate immune system which involves the recognition of ... -
Impact of ensiling conditions on formation of biogenic amines in grass and legume silages and feed intake behaviour of goats
Scherer, Rebecca (2019-05-14)Silage produced from small-grained legumes can contribute to the protein supply of ruminants. However, the susceptibility to protein degradation during harvest and the entire conservation process impedes to achieve high ... -
African nightshade and African spinach: A neglected and underutilized resource with significant potential to manage plant-parasitic nematodes
Chitambo, Oliver (2019-05-07)African indigenous vegetables (AIV) are essential for dietary diversification and ensuring nutritional requirements for people in sub-Sahara Africa. AIV have been largely marginalized by agriculture research, yet they are ... -
Direct use of urine as fertilizer: potential risks of loading pharmaceuticals and hormones to field crops
Arias Escobar, Maria Alejandra (2019-04-11)Ecological sanitation or Ecosan is an alternative approach to avoid the disadvantages of conventional water-based sanitation systems. This approach, based on ecosystem functioning and the closure of material flow cycles, ... -
Suitability of non-destructive sensors for monitoring physiological and biochemical responses of tomato leaves and fruits to abiotic stresses
Groher, Tanja (2019-05-02)The major aim of the present work was to proof the suitability of chlorophyll fluorescence-based indices to non-destructively monitor and predict changes in the content of plant compounds in response to abiotic stresses. ...
