  1. 1. Forest fertilization does not cause any long-term effects on tree growth or vegetation composition

    University essay from SLU/Dept. of Ecology

    Author : Yixian Chen; [2023]
    Keywords : density; ground vegetation; height; stem radial growth; legacy nitrogen effect; soil total N and C N ratio; tree;

    Abstract : Forest fertilization is considered one of the most effective management options to improve forest productivity. In Fennoscandia, nitrogen (N) fertilization has been practiced for over 50 years and is normally added in the form of granules of NH4NO3 at least 15 years prior to the final harvest. READ MORE

    Author : Jonathan R. Wilson; [2019]
    Keywords : local adaptation; population structure; selective sweep; synteny;

    Abstract : From a subset of P. tremula samples taken from across Europe and China, principal component analysis of genetic variation indicated population structure in the Scottish population compared with the rest of Eurasia. READ MORE

  4. 3. Planteringsförbandets inverkan på slutavverkningsbeståndets utseende och kvalitet

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Axel Sjödin; Eric Widegren; [2019]
    Keywords : beståndstäthet; kronegenskaper; föryngring; planteringsförband; kvalitet;

    Abstract : Med förband menas hur långt avstånd det är mellan plantor eller träd i ett bestånd. Förbandet kan variera mellan olika ytor beroende på vilken typ av bonitet marken har. Vid hög bonitet kan det planteras fler plantor än på ytor med sämre bonitet, vilket gör att planteringskostnader också varierar från bestånd till bestånd. READ MORE

  5. 4. Interfaces in complex InAs-GaSb heterostructured nanowires - A transmission electron microscopy study

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Louise Uhrgård Gren; [2017]
    Keywords : transmission electron microscope; TEM; aberration corrected S TEM; nanowires; core-shell nanowires; InAs-GaSb; advanced characterization; Technology and Engineering;

    Abstract : In this project epitaxially grown InAs-GaSb complex heterostructured nanowires have been characterized by means of aberration corrected TEM techniques and energy dispersive X-ray spectroscopy (EDX). The InAs-GaSb material is of interest due to its high charge carrier mobility, which has possible applications in electronic devices such as FETs. READ MORE
