Satellitenbasierte Indexversicherungen zur Absicherung des witterungsbedingten Produktionsrisikos in der Land- und Forstwirtschaft
(2021-11-04)This cumulative dissertation examines the hedging effectiveness of satellite-based weather index insurance for both annual crops, such as rice and wheat, and also perennial olive trees and pine stands. Unlike traditional ... -
Scale dependence of pollinator community turnover and tritrophic interactions in changing landscapes
(2015-01-23)Agricultural landscapes account for approximately 40% of global terrestrial area and this proportion tends to grow due to the increasing demand for fuel, food and other agricultural products. For successful crop production ... -
Scale effects on genomic modelling and prediction
(2015-08-24)In this thesis, a novel method for scale corrected comparisons of LD structure in different genomic regions is suggested. Several aspects of scale-caused problems – from precision of marker effect estimates to accuracy of ... -
Scale- and trait dependent responses of bird communties to lowland rainforest restoration and frugivore-bird-seed interaction networks in Sumatra, Indonesia
(2014-02-10)Recovery of tropical secondary forest will require human assistance. The first important part in forest restoration is understanding the existing biodiversity and ecosystem service within the secondary forest and use this ... -
Scales of bacterial interactions on the leaf surface
(2017-01-16)Microbial organisms are ubiquitous to habitats on Earth and they are important components in cycling of matter. This is true for the micro-scale and at global scale, and all spatial scales in between. In soils, aquatic ... -
Scaling of Animal Communities: From Local and Landscape to Global Processes
(2017-12-12)Animal communities are influenced by processes changing from the local to global scale. Local processes include resource and habitat availability, while landscape processes are often driven by habitat availability and ... -
Schätzverfahren für individuelles Preissetzungsverhalten im Lebensmitteleinzelhandel
(2018-01-12)The issue of transferring a price along the value-added chain of agricultural products, the so-called vertical price transmission (VPT), has once again become a matter of concern. The retail sector is suspected to operate ... -

(2004-10-21)In Jimma zone southwestern Ethiopia where the mainstay of the people is coffee and livestock production. A study was conducted on college of agriculture dairy farm and cattle"s of the ... -
Secondary metabolites in fungal biotic interactions
(2014-05-22)Fungi are known for their production of chemical and biological diversity of secondary metabolites. To understand the structure, biological activity and function of fungal secondary metabolites contribute to the development ... -
Selection and characterization of human recombinant antibodies against Orthopoxviruses from an immunoglobulin library and mapping of functional epitopes of Vaccinia virus surface proteins
(2020-04-07)The genus Orthopoxvirus (OPXV) contains a group of large (130-380 kb) and closely related double-stranded DNA viruses within the Poxviridae family, which replicates in the cytoplasm of vertebrate or invertebrate cells. ... -
Selection signature detection in a diverse set of chicken breeds
(2015-01-28)Over the last decade, interest in detection of genes or genomic regions that are targeted by selection has been growing. Identifying signatures of selection can provide valuable insights about the genes or genomic regions ... -
Selektion von Stangenbohnensorten (Phaseolus vulgaris L.) für den Mischanbau mit Mais
(2018-08-15)The mixed cropping of maize and climbing beans (Phaseolus vulgaris L.) is an interesting alternative to the pure cultivation of silage maize, as it potentially combines the high yield performance of maize with the ecological ... -
Selektionsexperimente zur Erhöhung des Männchenanteils bei Nilbuntbarschen (Oreochromis niloticus) mittels Temperaturbehandlung
(2007-01-02)Tilapia are one of the most important species in commercial aquaculture world wide. On the one hand this is due to their ability to utilize a broad variety of food sources. On the other ... -
Sensing and automatic scoring of sugar-beet fields by using UAV-imagery systems for disease quantification
(2024-04-19)Cercospora leaf spot (CLS) in sugar beet is a damaging leaf disease caused by the fungal pathogen Cercospora beticola Sacc. This disease leads to substantial yield diminishment, and its management poses a challenge owing ... -
Sequence-Based Analyses of the Goettingen Minipig Genome
(2018-07-27)Among the known pig breeds, the Göttingen Miniature Pig (GMP) stands out due to its special characteristics and history. Its current appearance dates back to the 1960´s when animal scientists from Goettingen took the effort ... -
Shaping climate-smart coffee landscapes
(2022-03-04)Coffee farming and the livelihoods of millions of smallholder farmers are threatened by climate change. Adopting climate-smart practices in coffee farming improves livelihoods of farmers and uses synergies between climate ... -
Shoot Cadmium Accumulation of Maize, Sunflower, Flax, and Spinach as Related to Root Physiology and Rhizosphere Effects
(2011-03-22)Plants differ widely in Cd accumulation when grown on Cd contaminated soils. This is because several soil properties interact with several plant properties. Plant factors determining the ... -
Shrub encroachment of temperate grasslands: Effects on plant biodiversity and herbage production
(2009-12-10)In Europe, semi-natural grasslands are an important resource of biodiversity and are, therefore, of high conservation interest. They are often invaded by shrubs, and they are threatened by ... -
