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. 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

5. 3. The impact of forest on pest damage, pollinators and pollination services in an Ethiopian agricultural landscape

   Author : Ulrika Samnegård; Kristoffer Hylander; Peter Hambäck; Sileshi Nemomissa; Jaboury Ghazoul; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; agroforestry; Apoidea; Coffea arabica; crop pests; Ethiopia; forest cover; landscape ecology; moist afromontane forests; pollination; species composition; tropical agriculture; Plant Ecology; växtekologi;

   Abstract : The distribution of wild biodiversity in agroecosystems affect crop performance and yield in various ways. In this thesis I have studied the impact of wild biodiversity, in terms of trees and forest structures, on crop pests, pollinators and the pollination services provided in a heterogeneous landscape in southwestern Ethiopia.

6. 4. 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%.
