  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  3. 2. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  4. 3. Estetiska värden hos gröna tak

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Stina Ekström; [2023]
    Nyckelord :gröna tak; extensiva gröna tak; takvegetation; kulturella ekosystemtjänster; urbanisering; klimat; hälsa; estetik;

    Sammanfattning : Grönblå infrastruktur och naturbaserade lösningar i staden blir allt viktigare med de klimatförändringar som pågår. I den urbana miljön kan gröna tak bidra med viktiga ekosystemtjänster för att t ex fördröja dagvattenavrinningen från tak, dämpa buller nära bygganden, rena luft, öka biologisk mångfald samt förbättra kulturella och estetiska värden.

  5. 4. Governance for Climate Change Adaptation in transboundary conservation areas A case study of La Amistad International Park (Pacific Side) between Costa Rica and Panama

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Ana Monroy Chaparro; [2023]
    Nyckelord :Climate change adaptation; Multilevel Governance; Transboundary conservation area; La Amistad International Park PILA; Earth and Environmental Sciences;

    Sammanfattning : El cambio climático es un problema global urgente que afecta a millones de personas y diversos ecosistemas. Sin embargo, existe una brecha significativa entre lo que se ha hecho y lo que es necesario para la adaptación al cambio climático. LÄS MER

  7. 5. Ecological impacts of dam removal in Swedish inland waters : Effects on water chemistry and fish demography

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Johanna Ekman; [2023]
    Nyckelord :biology; ecology; dam removal; Sweden; impact; inland waters; ecosystem; water chemistry; fish demography; Perca fluviatilis; European perch; biologi; ekologi; dammutrivning; Sverige; påverkan; inlandsvatten; ekosystem; vattenkemi; fiskdemografi; Perca fluviatilis; abborre;

    Sammanfattning : Dams play an important role in our society, but their negative impacts on aquatic ecosystems have led to a need for conservation efforts to mitigate the negative effects. In some instances, dam removal has been suggested to be the most economically and ecologically beneficial restoration method to improve longitudinal connectivity. LÄS MER
