  1. 1. Partners in crime – How cabbage seed weevil assists brassica pod midge in damaging pods of winter oilseed rape in fields in Southern Sweden : how is insect abundance related to crop damage?

    Kandidat-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Sarah Heithausen; [2020]
    Nyckelord :monitoring; Ceutorhynchus obstrictus; Dasineura brassica; Brassica napus; Integrated Pest Management; economic threshold; pan trap; sticky trap;

    Sammanfattning : The brassica pod midge (Dasineura brassicae) has emerged as an important pest causing problems in Winter Oilseed Rape (WOSR) (Brassica napus ssp. napus) production in Southern Sweden during recent years. Adult female D. brassicae oviposit into WOSR pods. LÄS MER

  2. 2. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Evangelos Oikonomopoulos; [2020]
    Nyckelord :Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Sammanfattning : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. LÄS MER

  3. 3. Replicating noise in video : a comparison between physics-based and deep learning models for simulating noise

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jonas Wedin; [2020]
    Nyckelord :;

    Sammanfattning : Algorithms that track objects in video following Newtonian physics can often be affected by noise in the data. Some types of noise might be hard or expensive to capture, so to be able to augment or generate a new data set from models replicating a certain type of noise can be useful. LÄS MER

  4. 4. OCTO

    Kandidat-uppsats, Lunds universitet/Industridesign

    Författare :Nina Cherrug; [2020]
    Nyckelord :Arts and Architecture; Technology and Engineering;

    Sammanfattning : Today’s sports glasses are great for rather extreme sports like biking, skiing and running often in tough weather conditions. They protect against wind, rain, blinding sun in the snow but also insects and dirt. LÄS MER

  5. 5. Park för biologisk mångfald : ett förslag för utformning med fokus på pollinerande insekter och fåglar

    Master-uppsats, SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Författare :Sofie Valtinat; [2020]
    Nyckelord :ekologisk design; gestaltning; indikatorarter; habitatkrav; solitärbin; humlor; dagfjärilar; fåglar;

    Sammanfattning : Biologisk mångfald minskar, och att ta hänsyn till den även i urban planering blir viktigare och allt vanligare. Urbanisering ses som en av de största faktorerna till minskad biologisk mångfald, men urbana områden kan även tillhandahålla habitat som gynnar en mängd arter. LÄS MER
