    Abstract : Att stoppa utarmning av biologisk mångfald och livsmiljöer är en stor utmaning och en ödesfråga för mänskligheten. Klimatförändringar, exploatering, kalhyggesskogsbruk, intensivt brukad jordbruksmark, invasiva arter och miljögifter medför att jorden är inne i sitt sjätte utdöende. READ MORE

  3. 2. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

    University essay from SLU/Dept. of Ecology

    Author : Bina Johansson; [2022]
    Keywords : volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

    Abstract : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. READ MORE

  6. 5. The Basis of Reproductive Isolation Between Ecologically Divergent Host Plant Races

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Emma Kärrnäs; [2018]
    Keywords : Biology and Life Sciences;

    Abstract : Insects and their host plants constitute a considerable proportion of the diversity on earth, and host shifts hence provide excellent study systems to study the process that drive diversification. In this study, I address what the mechanism to achieve assortative mating is in two host races using different host plants to increase our understanding of how reproductive isolation can arise in the face of ecological specialization.
