  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. Characterisation of the epistatic hybrid incompatibility locus STRUBBELIG RECEPTOR FAMILY 3 in Arabidopsis

    University essay from SLU/Department of Plant Biology (from 140101)

    Author : Fredrik Dölfors; [2018]
    Keywords : abiotic stress; arabidopsis; co-evolution; hybrid incompatibility; receptor-like kinase;

    Abstract : Populations of Arabidopsis thaliana have spread throughout temperate zones of the world and adapted to prevailing biotic and abiotic stress factors. Diverging popula-tions of Arabidopsis accessions can evolve postzygotic hybrid incompatibility (HI). READ MORE

  3. 3. Impact of plant ecotype on Bacillus-mediated growth promotion : extending beyond the standard model plant

    University essay from SLU/Dept. Of Plant Biology

    Author : Staffan Matzén; [2018]
    Keywords : bacillus; growth promotion; root exudates; volatiles;

    Abstract : This study investigated how bacterial treatment modulates plant growth. Bacillus amyloliquefaciens UCMB5113 was used for treatment of several different natural accessions (ecotypes) as well as mutants of Arabidopsis thaliana. Treatment effect on plant root architecture was studied in particular. READ MORE

  4. 4. Temporal spawning divergence in European whitefish (Coregonus lavaretus) : The first steps towards reproductive isolation in young populations (70-171 years)

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Petter Johansson; [2017]
    Keywords : Population divergence; Coregonus lavaretus; spawning whitefish; reproductive isolation; young populations;

    Abstract : A critical step in ecological speciation is the development of reproductive isolation. The processes leading up to reproductive isolation are difficult to study since they often occur over very long time periods. READ MORE

  5. 5. Taxonomisk indelning och bevarande av späckhuggaren

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Isa Persson; [2017]
    Keywords : späckhuggare; orcinus orca; ekotyper; artindelning; bevarandebiologi; taxonomi;

    Abstract : Späckhuggaren är världens största delfin och en av havens toppredator. Trots att späckhuggaren uppvisar specialiseringar med avseende på social sammansättning, val av bytesdjur och ibland har morfologiska olikheter är den idag betraktad som en monotypisk art. READ MORE
