1. 1. Betesrestaureringens effekter på växtartrikedom och biologisk mångfald : -restaurering av betesmark på Hallands Väderö

   Kandidat-uppsats, Karlstads universitet/Avdelningen för biologi; Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Rolfsdotter Söderberg Ylva; [2024]
   Nyckelord :pasture restoration; biodiversity; species richness; effective number of species; plants; plant species; number of species; clearing; pasture; betesrestaurering; biologisk mångfald; artrikedom; effektivt artantal; växter; växtarter; antal arter; artantal; hävd; betesmark; naturbetesmark;

   Sammanfattning : Abstract Pasture is a very species-rich but threatened nature type, and compared to 200 years ago, only five percent of natural pastures remain in Sweden. One way to try to save the biological diversity that pastures harbor is to restore overgrown land by clearing and reintroducing grazing animals. LÄS MER

3. 2. Land cover classification using machine-learning techniques applied to fused multi-modal satellite imagery and time series data

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

   Författare :Anastasia Sarelli; [2024]
   Nyckelord :Geography; GIS; Land Cover Classification; Landsat; Machine Learning; Earth and Environmental Sciences;

   Sammanfattning : Land cover classification is one of the most studied topics in the field of remote sensing, involving the use of data from satellite sensors to analyze and categorize different land surface types. There are numerous satellite products available, each offering different spatial, spectral, and temporal resolutions. LÄS MER

4. 3. How does grazing and burning affect the occurrence and development of vascular plants?

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

   Författare :Felicia Ivarsson; [2023-02-17]
   Nyckelord :Keywords: burning; grazing; plot; restoration; plant; flower;

   Sammanfattning : Grazing and burning are disturbances that can be used for management of landscapes that are in need of restoration. When applying these disturbances, you can create a more diverse flora and fauna and control the grazing pressure from domestic cattle. LÄS MER

5. 4. The effects of management practices and environmental variables on the biodiversity of Nardus grasslands in the national park Hohe Tauern, Austria

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Rebecca Paulina Dörner; [2023]
   Nyckelord :biodiversity; Nardus stricta; Nardus grassland; national park Hohe Tauern; East Tyrol; alpine pastures;

   Sammanfattning : Introduction. A large part of the biodiversity of the Alps is linked to an interaction between the natural environment and traditional land-use practices. This study focuses on the priority habitat type of species rich Nardus grasslands (Natura 2000 Code 6230*), which is endangered, but continues to thrive in extensively managed subalpine pastures.

7. 5. The potential nitrous oxide emissions in a permanent grassland chronosequence

   Kandidat-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

   Författare :Sandra Lillsjö Kronblad; [2023]
   Nyckelord :nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

   Sammanfattning : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.
