  1. 11. Parental Involvement & Parental Anxiety

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Kimon Naoum Alexiou; [2020]
    Nyckelord :Parental Involvement; Parental Anxiety; Social Sciences;

    Sammanfattning : This study aimed at examining the potential relations of parental involvement onto parents, namely the procurement of parent anxiety. A middle school in an area of middle to low socio-economic level was approached to conduct the survey and a hundred and fifteen (N = 115) participants completed questionnaires regarding their levels of parental anxiety and parental involvement, measured here as an average of five (5) other sub-variables and their involvement with their children’s academic life respectively.

  4. 13. Floristic change in the province of Scania in southernmost Sweden 1800-2020: using fragmented data to study landscape-level shifts

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Cassandra Hallman; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Vascular plant observances were compiled for 10 well-documented parishes throughout southernmost Sweden from published floras, herbarium specimens, modern inventories, and a large citizen-science database to provide presence/absence of species from 1800-2020 at the decade level. A regionally-specific database of species-specific plant traits and ecological indicator values was used to examine floristic and ecological changes across an extended timeline which indicates that several of the most apparent conservation issues including climate warming, woody encroachment, and soil chemistry alterations have acted for long over a century.

  5. 14. Alternative oxidase respiration in the mycorrhizal fungus Laccaria bicolor

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

    Författare :Hilda Mikaelsson; [2019]
    Nyckelord :L. bicolor; mycel; ektomykorrhiza; cellandning; AOX; alternativt oxidas; cytokromoxidas; cyanid; mycelium; ectomychorriza; respiration; alternative oxidase; cytochrome oxidase; salicylhydroxamic acid; n-propyl gallate; cyanide;

    Sammanfattning : The temperature on Earth is rising, and one of the main drivers is anthropogen-ic greenhouse gases such as carbon dioxide (CO2). The world’s forests act as carbon sinks, binding carbon into their biomass. The net carbon assimilation is determined by the uptake and release of CO2 through the processes of photo-synthesis and respiration. LÄS MER

  7. 15. Reindeer induced changes in vegetation composition and plant traits on a tundra-forest border

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

    Författare :Femke Pijcke; [2019]
    Nyckelord :physical geography; ecosystem analysis; plant functional traits; nutrient allocation; grazing; reindeer; Earth and Environmental Sciences;

    Sammanfattning : Reindeer (Rangifer tarandus) are the most common large herbivores in the arctic. With a habitat spreading over the entire circumpolar region, they can have a substantial effect on plant species composition and ecosystem processes and functions. LÄS MER
