  1. 1. 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.

  3. 2. Station-level demand prediction in bike-sharing systems through machine learning and deep learning methods

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

    Författare :Nikolaos Staikos; [2024]
    Nyckelord :Physical Geography; Ecosystem Analysis; Bike-sharing demand; Machine learning; Deep learning; Spatial regression; Graph Convolutional Neural Network; Multiple Linear Regression; Multilayer Perceptron Regressor; Support Vector Machine; Random Forest Regressor; Urban environment; Micro-mobility; Station planning; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : Public Bike-Sharing systems have been employed in many cities around the globe. Shared bikes are an efficient and convenient means of transportation in advanced societies. Nonetheless, station planning and local bike-sharing network effectiveness can be challenging. LÄS MER

  4. 3. 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

  5. 4. Ett vänerföretags val av logistik : efter kommande infrastruktursatsning på Göta älv

    Kandidat-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Tobias Magnusson; Oskar Nilsson; [2024]
    Nyckelord :CSRD; streamlining; cargo; inland waterways; logistics; maritime transport; lock; Trollhättan; Vänern; CSRD; effektivisering; gods; inre vattenvägar; logistik; sjötransporter; sluss; Trollhättan; Vänern;

    Sammanfattning : Ett företag står inför nya logistiska alternativ när förutsättningar förändras. Det kan handla om infrastrukturförändringar, men det kan också handla om lag- och regelförändringar när samhället vill skärpa krav på miljömedvetenhet och hållbarhetsredovisning. LÄS MER

  7. 5. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Walter Gezelius Gezelius; [2024]
    Nyckelord :Restoration; Environmental flows; riparian vegetation;

    Sammanfattning : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. LÄS MER
