  1. 21. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Simon Hannus; [2021]
    Keywords : Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

    Abstract : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

  3. 22. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ainahu Abdul Hamid; [2021]
    Keywords : Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Abstract : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. READ MORE

  4. 23. Topographic controls of drought impact on Swedish primary forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Johanna Asch; [2021]
    Keywords : Physical geography; ecosystem analysis; primary forest; boreal forest; drought impact; topography; drainage; climate change; random forest; terrain index; Earth and Environmental Sciences;

    Abstract : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. READ MORE

  5. 24. Effects of dead wood on arthropods in managed pine forests in Sweden

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Stephanie Jonsson; [2021]
    Keywords : Dead wood; arthropod; pest mitigation;

    Abstract : Forests provide humans with a range of valuable ecosystem services, but current forest management practices may increase susceptibility to damage from disturbances such as pest insects. One such practise is the harvesting of residue, which decreases the amount of dead wood in the forest. READ MORE

  6. 25. Change in surface area of semi-natural grassland in the Osby municipality, Scania and potential consequences for plant diversity

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Katharina Borgström-Lohde; [2021]
    Keywords : Land use change; Semi-natural grasslands; Biodiversity; Scania; Historical land use; Earth and Environmental Sciences;

    Abstract : During the past, land use has changed and still is. It has been recognized that land use changes affect biodiversity all over the world. In Sweden semi-natural grasslands are a habitat with high biodiversity. The topic of this thesis is how land use change has affected the habitat of semi-natural grasslands in the area around Osby, Scania. READ MORE
