  1. 41. Lake Vättern Fish: From the Water to the Consumers : ecosystem-based fisheries management assessment, fish & fish products distribution channels of lake Vättern

    University essay from SLU/Department of Molecular Sciences

    Author : Felix Isimemen-Wealth; [2021]
    Keywords : ecosystem-based fisheries management; adaptive co-management; Lake Vättern; supply value chain;

    Abstract : This study assessed the Ecosystem-Based Fisheries Management (EBFM) of Lake Vättern by using the EBFM objectives as spelt out by Engler et al. (2015) and Long et al. (2015). In order to fully understand the fish and fish products distribution channels, it was necessary to understand the lake’s fisheries and their management. READ MORE

  3. 42. Parkslide : kan förekomsten i olika jordar och miljöförhållanden ge indikationer på hur de kan bekämpas?

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Chasmine Carlsson; [2021]
    Keywords : parkslide; Reynoutria japonica; jord; pH; invasiv; miljöförhållanden; ståndort;

    Abstract : Parkslide känns igen på sitt bambuliknande utseende och är en storväxande flerårig ört. Den har sitt ursprung i östra Asien, i länderna Japan, Korea, Taiwan och Kina och kom till Europa från Japan på1820-talet genom en holländsk import. Från att ha odlats som prydnadsväxt i parker och trädgårdar har arten spridit sig ut i naturen. READ MORE

  4. 43. The effect of temperature on the interaction between larvae of a native and a range expanding dragonfly species

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Sanne Everling; [2021]
    Keywords : Climate change; temperature; native; invasive; competition; behaviour; Odonata;

    Abstract : Climate change might affect the distribution of species; therefore, it is important to anticipate the imminent impact of climate change. Even though climate responses have the potential to affect species interactions, most models on the effect of climate change on species distribution assume that species respond to climate individually.

  5. 44. Effects of active and passive conservation on forest structure and bird diversity in Färna Ecopark

    University essay from SLU/School for Forest Management

    Author : Arvid Sandström; [2021]
    Keywords : biodiversity; deciduous forest; avifauna;

    Abstract : Voluntary set-asides are an important part of the conservation of forest species in Sweden. Set aside stands are either treated passively by leaving them untouched (in Swedish abbreviated as NO) or with active, often invasive maintenance (NS). READ MORE

  6. 45. Quantifying changes in soil bioporosity in subarctic soils after earthworm invasions

    University essay from

    Author : Joel Fransson Forsberg; [2021]
    Keywords : Biopores; macropores; geoengineering earthworms; X-ray tomography;

    Abstract : Pores provide important hotspots for chemical and biological processes in soils. Earthworm burrows affect the macropore structure and their actions may create new preferential pathways for water and gas flow within soils. This, in turn, indirectly affect plants, nutrient cycling, hydraulic conductivity, gas exchange, and soil organisms. READ MORE
