1. 21. Consequences of alternative forest management in riparian buffer zones : a GIS analysis

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

   Författare :Elijah Ourth; [2023]
   Nyckelord :Riparian buffer zones; Continuous cover forestry; CCF; Hyggesfritt; Geographical information system; Ditch network maintenance; Ditch; Stream; Natural channel;

   Sammanfattning : With increasing pressure from policymakers and the general public to conduct alternative forest management throughout the European Union (EU), Sweden needs to find ways to best prioritize the implementation of this alternative management. Alternative management is a term used to describe alternative management methods to clear-cut rotation forestry and can include silvicultural methods such as continuous cover forestry, management increasing proportion tree diversity and presence of broadleaves, and extended rotation lengths.

3. 22. Effekten på artsammansättning i växtsamhällen vid betning av Rangifer tarandus

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Emilie Voss-Schrader; [2023]
   Nyckelord :grazing pressure; Rangifer tarandus; species composition; vegetation analysis; Malla Strict Nature Reserve;

   Sammanfattning : The fact that large herbivores, such as Rangifer tarandus, play a part in shaping its environment through grazing and trampling of the ground is widely acknowledged today, as well as that these factors have the potential of affecting regional patterns and even global climate. This study investigated whether a considerable increase in grazing by R. LÄS MER

4. 23. Influence of structural complexity of the Rumperöd forest on evapotranspiration

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

   Författare :Madeleine Durdek; [2023]
   Nyckelord :Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

   Sammanfattning : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. LÄS MER

5. 24. 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. 25. Effects of climate, soil, and forest structure on specific leaf area of understorey foundation plants

   Master-uppsats, SLU/Southern Swedish Forest Research Centre

   Författare :Sashank Khaniya; [2023]
   Nyckelord :Specific leaf area; understorey vegetation; foundation species; forest structure; climate change;

   Sammanfattning : Forest overstorey's interaction with understorey vegetation is a crucial aspect that impacts the biodiversity and resilience of forest ecosystems. Particularly, the influence of the overstorey on the specific leaf area (SLA) in understorey plants remains poorly understood. LÄS MER
