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

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Forest Ecology and Management

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

    Abstract : 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. 3. Can precommercial thinning be used to create more diversity after planting spruce?

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Astrid Bygge; [2024]
    Keywords : Forestry; pre-commercial; stand structure; heterogeneity; silviculture; mixed forests; monoculture; Picea abies; Betula spp.;

    Abstract : Mixed forests will harbour other ecosystem services than a planted coniferous monoculture. This study used early results from a long-term experiment to examine if different precommercial thinning treatments can be used to increase diversity in planted stands of Norway spruce (Picea abies) mixed with high densities of natural regeneration of birch (Betula spp. READ MORE

  4. 4. Major forest companies and owner associations interpretation of policies and certification programs regarding riparian buffer zones

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Eric Lundström; [2023]
    Keywords : Buffer zone; Water quality; Buffer zone policy; Forestry; Policy interpretation;

    Abstract : Human intervention in forests such as clearcut forestry have a negative impact on water quality and biodiversity. To maintain water quality and its biological values a commonly used method is to leave trees and shrubs closest to the water, in so called a buffer zone. READ MORE

  5. 5. Streamlining the flow of material through buffer simulation and multi-objective optimization, with regards to sustainability : A case study at Volvo Construction Equipment

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Daniel Nord; Alex Wernholm; [2023]
    Keywords : Multi-Objective optimization; Buffer Allocation Problem; Simulation modeling; FACTS Analyzer; Buffer allocation; Optimization; Buffers; Lean; Manufacturing; Streamlining; Sustainability; Flow of material; Design of Experiments; Gemba walk; Data visualization;

    Abstract : This thesis will provide knowledge on how to maintain a well developed flow of material while at the same time finding an optimal level of capacities for buffers. Simultaneously, aspects that allow for positive sustainability practices will be regarded.  Buffers have a considerable impact on the performance of a production system. READ MORE
