  1. 1. Restaurering av grässandhedar genom aktiv markstörning - en jämförelse av florans kolonisation av plöjningar och sandblottor på Revingefältet utanför Lund

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Erik Borgström; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The conservation value of sandy habitats for a flora and fauna adapted to open, light, dry, warm, and often nutrient-poor conditions, is well recognized. Today this environment is threatened by lack of disturbance, fragmentation and exploitation, acidification and increased levels of nitrogen and phosphorus. LÄS MER

  3. 2. Beetle Diversity – Land Sparing or Land Sharing? : the effects of timber extraction and restoration method on saproxylic beetle assemblages in mature managed pine forests

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

    Författare :Ella Amnéus; Sebastian Hjelström; [2023]
    Nyckelord :Saproxylic Beetles; Ecological Restoration; Deadwood; Biodiversity; Boreal Forest; Fire Ecology; Land-sparing; Land-sharing; Conservation Management;

    Sammanfattning : The impoverishment of saproxylic beetle communities is a growing concern for management of boreal forest biodiversity. Past research has found active restoration methods, such as creating deadwood and conducting prescribed burnings, to have a short-term positive effect on the species richness and compositional diversity of saproxylic beetle assemblages.

  4. 3. Increased carbon sequestration of actively restored tropical forests in Sabah, Malaysia : a comparison of natural regeneration and active restoration

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

    Författare :Johan Engström; [2023]
    Nyckelord :Degraded tropical forest; Active restoration; Carbon sequestration; Natural regeneration; Enrichment planting; Biomass accumulation;

    Sammanfattning : As restoration with assisted natural regeneration and enrichment planting becomes a more important and popular method to restore ecosystem services and mitigate negative climate effects, these treatments and their effectiveness is heavily debated. There are three main groups of opinions regarding restoration, one is that humans actively need to help nature recover and the second is that nature itself does a better job without our help and the third is somewhere in between.

  5. 4. Habitatpreferens hos Anguilla anguilla: makrofyters påverkan på gulålars habitatval under dag och natt

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Hannah Wiklund; [2023]
    Nyckelord :European eel; Anguilla anguilla; Yellow eel; Habitat preference; Macrophytes; Substrate; Europeisk ål; Anguilla anguilla; Gulål; Habitatpreferens; Makrofyter; Substrat;

    Sammanfattning : Aquatic vegetation and different substrates can be important factors for fish habitat. The European eel (Anguilla anguilla) is threatened by habitat loss in freshwater systems during its life stage as a yellow eel. To conserve the species, restoration measures and increased knowledge about its preference for benthic habitats are needed. LÄS MER

  7. 5. Ekoparkernas inverkan på långhornskalbaggar (Cerambycidae) : artrikedom, abundans och artsamhällen i jämförelse med kommersiellt brukad skogsmark

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

    Författare :Elias Skogqvist; Emil Andersson; [2022]
    Nyckelord :naturvård; aktiv restaurering; död ved; substrat; rödlista; unika arter;

    Sammanfattning : Several dead wood-dependent beetles need substrates which to great extent have been disfavored by intense forestry. Active and continuous restoration in Ecoparks may offer an option with intention to improve the habitation conditions. LÄS MER
