    Author : Matilda Apelqvist; [2022]
    Keywords : Detection dog; indicate synthetic pheromone; coleoptera; conservation biology; endangered species;

    Abstract : Using dogs to detect insects’ emitted volatiles is a non-invasive procedure, and a trained detection dog is potentially a fast and accurate method to search for saproxylic insects. The longhorn beetle Plagionotus detritus is categorized as Endangered in the Swedish Red List of Threatened Species. READ MORE

    Abstract : Alléodling innebär att vedartade perenner, främst träd, planteras i rader varpå annuell gröda odlas mellan dessa rader. Systemet har mycket gamla anor men har till stor del har blivit bortglömt i och med jordbrukets intensifiering. READ MORE

  4. 3. Host plant selection in closely related butterfly species due to reproductive interference: Modelling a tritrophic system

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alexandros Bantounas; [2021]
    Keywords : reproductive interference; habitat selection; modelling; phytophagous insects;

    Abstract : Host plant selection is an important process during the life cycle of lepidopterans, providing ovipositing sites for adults and food resources for the larvae. The processes behind host plant selection have been extensively studied, especially in closely related species in the context of niche separation. READ MORE
