  2. 1. 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

  4. 2. The effect of climate on oak-based species interactions : annual number of leaf flushes and insect voltinism

    Author : Álvaro Gaytán; Ayco J. M. Tack; Karl Gotthard; Kailen A. Mooney; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; food webs; latitude; leaf flush; plant-based species interactions; Quercus robur; voltinism; Ecology and Evolution; ekologi och evolution;

    Abstract : Plants interact with a large diversity of organisms, including insects and microorganisms. These species interactions are strongly influenced by climate, as illustrated by the advances in plant and insect phenology in response to increasing temperatures. READ MORE

  5. 3. 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

  6. 4. Plant-associated soil communities : Patterns, drivers and aboveground consequences

    Author : Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aboveground-belowground interactions; arbuscular mycorrhiza; climate; dispersal; environmental drivers; fungi; genetic variation; nematodes; plant-herbivore interactions; soil communities; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Abstract : Soil contains a wealth of diversity – bacteria, fungi, nematodes, arthropods and earthworms are just some of the many organisms found belowground. These organisms play an important role in shaping the soil environment and they strongly influence plant fitness, diversity and community composition. READ MORE

  7. 5. Interactions between plants, microbes and insects

    Author : Laura J. A. van Dijk; Ayco J. M. Tack; Arjen Biere; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aboveground–belowground interactions; Anemone nemorosa; fungal pathogens; insect herbivores; plant–pathogen–insect interactions; pollination; soil microorganisms; spatiotemporal disease dynamics; Quercus robur; ekologi och evolution; Ecology and Evolution;

    Abstract : Plants interact with an astonishing diversity of insects and microorganisms. Both above- and belowground, plants are attacked by herbivores and pathogens, and interact with mutualists such as pollinating insects and beneficial microorganisms. READ MORE
