    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. Antenna Arrays for Dual-Frequency Harmonic Radar Application

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Venkatesh Raja; Mohammad Zafar Mohammad; [2023]
    Keywords : Technology and Engineering;

    Abstract : The aim of this thesis is to design two patch antenna arrays for dual-frequency harmonic radar application, one for the transmitter and the other for the receiver. The arrays are used to track the Bogong moth that migrates from the countryside to the Australian Alps during spring. READ MORE

  4. 3. Insects in conifer logs : their association to the polypore fungi Amyloporia sinuosa, A. xantha and Neoantrodia serialis and impact of aggregations of wood

    University essay from SLU/Dept. of Ecology

    Author : Tore Dahlberg; [2023]
    Keywords : polypores; dead wood volume; Amyloporia sinuosa; A. xantha; Neoantrodia serialis; Nemapogon fungivorellus; Agnathosia sandoeensis;

    Abstract : A large number of insects are associated with polypores. They can be monophagous, polyphagous and use several fungal hosts, or be parasites on the insects utilize the fungus. The insect assemblage for some polypores is well investigated but there is still a lack of knowledge for many species. READ MORE

  5. 4. The diversity of moths in a nature reserve in the Northern Cape, South Africa : Variation over time, depending on abiotic factors and differences between areas with different grazing types

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Nellie Jarl; [2023]
    Keywords : Moth diversity; grazing effects; land use; biodiversity;
