  1. 1. An attempt to promote ground-nesting bees in an urban landscape. Investigating the use of sand beds as a conservation effort.

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Bodil Mattson; [2024-02-16]
    Nyckelord :ground-nesting bees - pollinator conservation - sand beds – conservation in urban parks;

    Sammanfattning : Pollinators provide crucial services for the ecosystems by pollinating around 80-90% of all plants. However, pollinating insects are declining worldwide which may cause a parallel decline in plant species leading to large biodiversity losses. LÄS MER

  3. 2. Unraveling Paradoxical Tensions in Digital Servitization Ecosystems : A case study in the mining industry

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Johannes Åström; Jakob Karlelid; [2024]
    Nyckelord :Digital servitization; Ecosystem; Paradoxes; Tensions; Digital tjänstefiering; Ekosystem; Paradoxer; Spänningar;

    Sammanfattning : Purpose - This study aims to understand what paradoxical tensions arise within an ecosystem when companies collectively pursue digital servitization and how these tensions impact value co-creation. Method -  The study is an explorative single-case study based on the mining industry in Sweden and involves respondents from industry-leading organizations. LÄS MER

  4. 3. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  5. 4. Wireless Sensor Network for Controlling the Varroasis Spread within Bee colonies across a Geographical Region

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Venkat Sai Akhil Dasyam; Saketh Pokuri; [2024]
    Nyckelord :Wireless Sensor Networks; Monitoring and Control; Precision Beekeeping; Disease spread; Internet of Things.;

    Sammanfattning : Background: With the global decline of honey bee populations, safeguarding these vital pollinators has become crucial. Varroa destructor mites are a primary threat, weakening bees and facilitating the spread of diseases, which can decimate colonies and disrupt ecosystems. LÄS MER

  7. 5. Reaching Food Security: The legislative challenges of Seed exchange in kind : a discourse analysis of the European Commission’s PRM proposal

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Anna Beskow; [2024]
    Nyckelord :Food Security; Food Sovereignty; European Commission; Seed exchange in kind; discourse analysis;

    Sammanfattning : On the 5th of July 2023, the European Commission presented a new Plant Reproductive Material directive with a general objective of ensuring high quality and diversity that contributes to food security, protects biodiversity, and restores forest ecosystems. The aims are to increase efficiency and promote and support mainly sustainable innovation. LÄS MER
