  1. 1. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

    Author : Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

    Abstract : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. READ MORE

  2. 2. Costa Rican coffee and bananas : A social-ecological study of management practices and their effects on the environment

    Author : Angelina Sanderson Bellamy; Micheal Tedengren; Charles Francis; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Costa Rica; coffee; banana; production system; pesticides; organic; conventional; Rainforest Alliance certification; Biology; Biologi; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : This thesis investigates the variability in management practices on coffee and banana farms in an attempt to identify practices that reduce the environmental impact of export crop production. Different banana production systems are studied to determine their level of environmental impact. READ MORE

  3. 3. Coffee and gene interaction. The effect on methionine and lipid metabolism

    Author : Elisabeth Strandhagen; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : coffee; homocysteine; cholesterol; folate; pyridoxine; MTHFR; APOE; gene; polymorphism; interaction;

    Abstract : Background: Different dietary factors influence the risk of coronary heart disease (CHD), most likely in an interaction with genetic polymorphisms. The knowledge about such interactions is insufficient. Some observational studies have shown an association between coffee and CHD, others have not. Coffee consumption affects some CHD risk factors, e. READ MORE

  4. 4. Does Voluntary Governance Work? : Insights from Specialty Coffee

    Author : Finlay Macgregor; LUCID - Lund University Centre of Excellence for Integration of Social and Natural Dimensions of Sustainability-lup-obsolete; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; regulatory governance; sustainability science; voluntary governance; certification; disclosure; sustainability reporting; coffee; Reglering och styrning; hållbarhetsvetenskap; frivillig reglering; certifiering; rapportering; kaffe;

    Abstract : Agricultural businesses contribute to sustainability problems, but they are also increasingly central to the effort to develop solutions. One way of moving toward sustainability is through regulatory governance. In this thesis, I analyze a tool of regulatory governance called voluntary market-based regulatory initiatives. READ MORE

  5. 5. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals

    Author : Michael Agthe; Lennart Bergström; German Salazar-Alvarez; Tommy Nylander; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; iron oxide nanocubes; mesocrystal; small angle X-ray scattering; video microscopy; QCM-D; materialkemi; Materials Chemistry;

    Abstract : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.
