  2. 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 : 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

  4. 2. Coffee and gene interaction. The effect on methionine and lipid metabolism

    Author : Elisabeth Strandhagen; Göteborgs universitet; []
    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

  5. 3. Genetic polymorphisms in breast cancer in relation to risk and prognosis

    Author : Erika Bågeman; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; age at diagnosis; breast cancer; polymorphism; CYP1A2; IGF1; GSTM1; CYP2C9; CYP2C8; coffee; GSTT1; ER; parity;

    Abstract : Breast cancer is the most common cancer in women living in Sweden and the second most common cancer in the rest of the world. The risk of developing breast cancer is modified by environment, lifestyle, genetics and a combination of these factors. READ MORE

  6. 4. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers

    Author : Biruk Ayalew Nurihun; Ayco J. M. Tack; Kristoffer Hylander; Ivette Perfecto; Stockholms universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Agroforestry; Arabica coffee; climate change; fungal disease; host-hyperparasite interaction; insect pest; minimum temperature and maximum temperature; shade cover; shade tree species; smallholder farmers; yield; Ecology and Evolution; ekologi och evolution;

    Abstract : Climate change and diseases are threatening global crop production. Agroforestry systems, which are characterized by complex multispecies interactions, are considered to provide nature-based solutions for climate change mitigation and pest and disease regulation. READ MORE

  7. 5. Root-knot nematodes and coffee in Nicaragua : management systems, species identification and genetic diversity

    Author : Isabel Cristina Herrera Sirias; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The coffee production is affected by several limiting factors such as parasitic nematodes. Plant-parasitic nematodes have a substantial economic impact on coffee production in most countries and they are regarded as one of the major limiting factors in coffee production and worldwide coffee losses have been estimated to about 15%.
