  1. 1. Bumblebee resource dynamics : a review of foraging and nesting in the agricultural landscape

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Anna Douhan Sundahl; [2020]
    Nyckelord :bumblebees; bumblebee population dynamics; bumblebee drivers; flower strips; competition with honeybees; foraging; nesting; hibernation;

    Sammanfattning : 90 % of all plants on earth either benefits or entirely depends on pollination. There are pollinators among families of bees (Apidea), butterflies (Lepidoptera) and birds (Aves). Bees of genus Bombus spp., bumblebees, are especially important and provide pollination service for 80 % of the crops of Europe and many wild plant species. LÄS MER

  2. 2. Ashish Vivekar (2020) Evaluation of methodology for estimating crop yield from multispectral UAV images : a case study at Lönnstorp, Sweden

  4. 4. Analys av gener och arter i metagenomikdata

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Sofia Bäckström Lebens; Emma Eriksson; [2019-06-14]
    Nyckelord :;

    Sammanfattning : As new extreme high throughput DNA sequencing methods continue to develop thelarge amounts of information that they give rise to in terms of metagenomic data opensthe way for completely novel approaches to the study of microbial ecosystems. In thisproject we have investigated how relationships and connections between microbial genesand species that carry them can be found based entirely on their appearance in twoseparate datasets accumulated from the same samples using metagenomic analysis.

  5. 5. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

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

    Författare :Shuo Yang; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

    Sammanfattning : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. LÄS MER
