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

    Författare :Biruk Ayalew Nurihun; Ayco J. M. Tack; Kristoffer Hylander; Ivette Perfecto; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Spatial and temporal ecology of oak-associated fungal communities

    Författare :Maria Faticov; Ayco Tack; Peter Hambäck; Paula Baptista; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic and biotic forces; climate warming; community ecology; foliar fungal community; host genotype; plant microbiome; powdery mildew; seasonal dynamics; warming-by-genotype interaction; Quercus robur; soil fungal community; spatial patterns; ekologi och evolution; Ecology and Evolution;

    Sammanfattning : Plants host a large diversity of microorganisms, which includes fungi, bacteria and archaea. Among these, fungi are highly diverse, and known to play a vital role in plant health and in regulation of the essential ecosystem functions. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Plant-associated soil communities : Patterns, drivers and aboveground consequences

    Författare :Pil Uthaug Rasmussen; Ayco J. M. Tack; Martijn Bezemer; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
