21st Century Challenges in Arable Farming - Essays on the Agricultural Land Market and Drone Adoption in Germany
(2021-09-09)This cumulative thesis addresses two key challenges facing modern arable farming in Germany in the 21st century. The first challenge considered is the agricultural land market. The ongoing reduction in the limited production ... -
A remote sensing and geospatial statistical approach to understanding distribution and evolution of ignimbrites in the Central Andes with a focus on Southern Peru
(2014-03-25)This PhD thesis investigates timing, cause and location of “ignimbrite flare ups” during the evolution of the Central Andean uplift and relates volcano-tectonic structures and calderas with shallow intrusive stocks to ... -
A Taxonomy of Inverse Priming Based on Stimulus Characteristics
(2011-11-28)One intriguing question in cognitive neuroscience is whether subliminal stimuli can affect overt behavior. A straightforward experimental approach to demonstrate effects of subliminal stimuli ... -
Above- and belowground biomass and nutrient stocks in monoculture and agroforestry cacao production systems in the Alto Beni, Bolivia
(2022-03-08)There is hardly any place left on earth that can be considered untouched nature. Humans penetrate into all areas of this earth, and may it be through greenhouse gas emissions or other types of air and environmental pollution. ... -
Active Emulsions: Physicochemical Hydrodynamics and Collective Behavior
(2021-07-02)Active matter is a collection of constituent elements that constantly consume energy, convert it to mechanical work, and interact with their counterparts. These materials operate out of equilibrium and exhibit fascinating ... -
Aculops lycopersici Tryon (Acari: eriophyoidea) monitoring, control options and economic relevance in German tomato cultivation
(2024-02-02)The tomato russet mite Aculops lycopersici Tryon (Eriophyoidea) is a damaging pest in commercial tomato production in many countries, including Germany. This mite feeds on the surface cells of leaves, stem and fruit. This ... -
Agricultural Policy Support, Production Incentives and Market Distortions in Sub-Saharan Africa
(2016-07-18)Most countries in the world adopt policies in support of their agricultural sectors. In doing so, governments seek to influence farmers’ behaviour through various channels. While these policies and their incidence have ... -
Air Surface Temperature Estimation Using MODIS Land Surface Temperature Data in Northwest Vietnam
(2019-07-26)There is increasing demand for air surface temperature (Ta) data that can capture information for a large area or for a region, since this kind of data is an important parameter for a wide range of applications. However, ... -
Alignment-free Phylogeny Reconstruction Based On Quartet Trees
(2020-03-11)Traditional methods for phylogeny reconstruction are based on multiple sequence alignments and character-based methods. This combination of computationally expensive methods leads to very accurate results, but it is ... -
Allometric structure and topology of food webs: Energetic constraints conserve food-web structure across ecosystems and space
(2014-07-23)Natural ecosystems comprise an innumerable amount of different organisms. These organisms are not separated, they interact and depend on each other. Today’s ecosystems are facing an enormous decline in biodiversity due to ... -
Altercentric Bias: A Potential New Window into Implicit Theory of Mind
(2023-07-24)It has been traditionally assumed that theory of mind (ToM) -our ability to ascribe mental states to others and ourselves- emerges around age four, as indicated in performance on standard explicit false belief (FB) tasks ... -
An integrated approach to the study of biosignatures in mineralizing biofilms and microbial mats
(2011-02-02)In this thesis project, biomarkers, biomineralization processes and TREE (trace and rare earth elements) patterns in mineralizing microbial mats were established and tested as biosignatures ... -
Anaerobic oxidation of methane in paddy soil
(2020-11-18)The anaerobic oxidation of methane (AOM) is a globally important CH4 sink that offsets potential CH4 emission into the atmosphere. AOM is estimated to consume up to 90% of CH4 produced in marine sediments before it reaches ... -
Analyse des Entscheidungsverhaltens landwirtschaftlicher Unternehmer: Anwendung von Discrete Choice Experimenten in den Bereichen Tierwohl, Weidehaltung und Ackerbau
(2019-02-22)The thesis contributes to the understanding of farmers decision behaviour. Preferences and decisions of farmers were analyzed using discrete choice experiments. In detail, the thesis deals with the topics animal welfare, ... -
Analyses of hydrological and hydrochemical fluxes in selected catchments of the Cerrado and Amazon biomes
(2019-03-12)On many levels, there is a lack of understanding regarding the impacts of deforestation on water resources and soil properties in the Amazon-Cerrado ecotone, where the Amazonian agricultural frontier is mostly present. ... -
Analyses on the Mitigation of Environmental Pollution by Nitrogen from Agriculture – Selected Indicators and Regulatory Policy Options to Improve Nutrient Management
(2023-07-28)Nitrogen (N) supply is essential for sustainable and cost-effective crop production, but losses of reactive N from agricultural activities pose a major ecological threat, with negative impacts on biodiversity, climate, ... -
Analysis of Consumer Attitudes, Preferences, and Demand for Poultry Meat in Ghana
(2020-06-09)Over the past decade, changing consumer preferences for variety, convenience, safer, and healthier attributes have been shaping meat demand patterns in sub-Saharan Africa (SSA), especially in Ghana. Some of these changes ... -
Analysis of expression profile and gene variation via development of methods for Next Generation Sequencing data
(2018-11-27)Since the last ten to twenty years, the cost of sequencing the human genome decreased continuously. Therefore the interest in RNA sequencing (RNA-Seq) rose as it can be used to discover the molecular mechanisms behind ... -
Analysis of solar faculae using stray-light-corrected spectropolarimetric data and numerical simulations
(2022-04-28)The objective of this thesis is to develop methods to improve the quality of restored ground-based observations, and to use such restored observations, along with 3D radiative MHD simulations, to study the properties of ... -
