  2. 16. Light-phyllosphere interactions in greenhouse grown ornamentals

    Author : Samareh Gharaie; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Light-emitting diodes (LEDs) have emerged as a promising artificial lighting source in greenhouse production of horticultural crops, as they reduce energy consumption. However, changes in lighting technology are known to affect abiotic and biotic interactions in the phyllosphere, e.g. READ MORE

  4. 17. 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

  5. 18. Habitat use in fish communities : size- and environment-dependent mechanisms affecting biotic interactions and population regulation

    Author : Ulrika Beier; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Through the influence of abiotic factors, the habitat use of organisms affects their metabolism as well as other species- and size-dependent individual-based rates. The habitat-specific performances of individuals interacting in different habitats thereby affect biotic interactions. READ MORE

  6. 19. Plant sex effects on biotic interactions in dioecious willow : plant sex-specific effects on interactions between Salix viminalis and its herbivores, pollinators and fungal disease

    Author : Kim Moritz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Sex in dioecious plants affects interactions between plant individuals and the organisms consuming them. Plant-herbivore interactions are affected by plant sex across many plant families, and plant-pathogen infections can be strongly sex-biased. READ MORE

  7. 20. Black mustard and the butterfly effect : metabolomics of plant-insect interactions under multiple stress conditions

    Author : Stefano Papazian; Benedicte Albrectsen; Edward Farmer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plant physiology; metabolomics; glucosinolates; multiple stress; ozone; Brassica nigra; Pieris brassicae; Brevicoryne brassicae; biology; biologi; Environmental Science; miljövetenskap; molekylärbiologi; Molecular Biology; Entomology; entomologi;

    Abstract : One main goal of ecological research is to understand nature´s complexity, in order to predict the potential impact of environmental perturbations. In this thesis, I investigate the ecological interactions between some of the most ancient organisms living on our planet: plants and insects. READ MORE
