  1. 1. Kan man skapa en artrik ängsmark på gammal åkermark? - kärlväxtetablering och vegetationsutveckling på MAX IV-området, Lund

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Janne Kolehmainen; [2016]
    Nyckelord :Biology and Life Sciences; Earth and Environmental Sciences;

    Sammanfattning : This study investigates if transfer of plant material in the form of hay is an effective method for establishment of species rich grassland on former arable land in southwestern Scania, Sweden. An inventory of vascular plants was conducted to analyze the early establishment on areas with added hay vs. areas with no hay added. LÄS MER

  3. 2. Using Worldview-2 satellite imagery to detect indicators of high species diversity in grasslands

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

    Författare :Oskar Löfgren; [2013]
    Nyckelord :Physical Geography and Ecosystem Science; GEM; grasslands; plant species diversity; remote sensing; generalized additive modelling; Worldview-2; Earth and Environmental Sciences;

    Sammanfattning : The high small-scale diversity of plant species in semi-natural grasslands can be seen as a function of environmental conditions and land use history. This study explores the potential of using Worldview-2 spectral imagery and accessible GIS data to identify a set of vegetation characteristics known to influence biodiversity in semi-natural grasslands.

  4. 3. Träd och buskar i kantzoner : en undersökning av kanteffekter i några av östersjöregionens skogar

    Kandidat-uppsats, Institutionen för livsvetenskaper

    Författare :Kersti Jernberg; [2011]
    Nyckelord :Fragmentations; edge habitats; core habitats; R; Ellenberg indicators; Fragmentering; kanthabitat; mitthabitat; R; Ellenberg-värden;

    Sammanfattning : Around the world, forests are generally being fragmented and as plant populations decline in both sizeand number of individuals, the genetic variation will also decrease whitch in the end leads to totalextinction of the plant. In this paper, I wanted to investigate what specific species of trees and shrubsyou usually find in the edge and core habitats in some of the forests in the Baltic Sea region. LÄS MER

  5. 4. Impacts on plant communities by elevated CO2 concentration

    L3-uppsats, SLU/Dept. of Environmental Assessment

    Författare :Miia Liisa Persson; [2005]
    Nyckelord :carbon dioxide concentration; plant communities;

    Sammanfattning : Our climate is in change. Carbon dioxide (CO2) levels this high, as the present CO2 concentration (≈370 ppm), have not been seen for the past 420 000 years. LÄS MER
