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

    University essay from SLU/Department 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.

  2. 2. Swedish wheat in the changing climate : screening for stable spring wheat genotypes from 2017 and 2018 with focus on protein quality for bread-making

    University essay from SLU/Department of Plant Breeding (from 130101)

    Author : Axel Belsing; [2021]
    Keywords : wheat; gluten protein; bread-making quality; stability; climate variation; breeding; SE-HPLC; micro-structure;

    Abstract : In recent years, wheat production and protein quality in wheat have been affected by climatic changes in Sweden and in many other parts of the world. Protein quality of wheat, determining the bread-making quality of flour, is a parameter sensitive to climate fluctuations and its stability has not been studied so far. READ MORE

  3. 3. Impact of experimental soil moisture manipulation on tropical tree seedling demographic fates and functional traits

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildningUppsala universitet/Institutionen för ekologi och genetik

    Author : Roel Lammerant; [2021]
    Keywords : Tropical forest; Drought; Seedlings; Experimental;

    Abstract : In tropical regions, climate change is predicted to lead to increased drought frequency and intensity. The extent to which this will shift the functional diversity of tropical tree communities is unknown due to a limited understanding about the response of seedlings to variable soil moisture.

  4. 4. Dynamics of streamflow and stream chemistry in a Swiss pre-Alpine headwater catchment : A fine scale investigation of flow occurrence and electrical conductivity in the temporary streams in the lower Studibach catchment

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära; Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elise Baumann; Hanna Berglund; [2021]
    Keywords : Temporary Streams; Pre-Alpine Catchment; Streamflow; Stream Chemistry; Fine Scale Investigation; Electrical-conductivity; Stream Mapping; Temporära bäckar; Pre-Alpina avrinningsområden; Bäckflöden; Vattenkemi; Finskalig undersökning; Elektrisk konduktivitet; Bäck-kartering;

    Abstract : Temporary streams and their dynamics have often been largely overseen in hydrological research and there is relatively little knowledge about how the occurrence of flow in these streams varies temporally and spatially. Temporary streams are important from a hydro- logical perspective because they affect water quantity and quality in downstream peren- nial reaches, and from an ecological perspective because they provide habitat to unique species.

  5. 5. Evaluation of in vitro antagonism assays in the mycoparasitic fungus Clonostachys rosea

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Victor Olsson; [2020]
    Keywords : Biocontrol; Biocontrol agent; Clonostachys rosea; Fusarium gramine-arum;

    Abstract : Fungicide use is the dominant direct method to control fungal pathogens on crops in agriculture. While effective, excessive use of them can be harmful to biodiversity and lead to fungicide resistance in pathogen populations. Biocontrol is an alternative where natural antagonistic organisms, called biocontrol agents (BCA), are used to protect crops. READ MORE
