  1. 1. The relative contribution of CNVs and SNPs to local adaptation in Norway spruce (Picea abies)

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Yuxuan Niu; [2022]
    Keywords : CNVs; SNPs; Norway spruce; local adaptation;

    Abstract : In the current environment of severe climate change, studying the adaptability of Norway spruce to the environment, that is, local adaptation is of great significance for helping to protect forest tree species and genetic breeding. As a structural variation, copy number variations (CNVs) have been proved to play an important role in shaping population structure and local adaptation in marine species, going beyond traditional studies focusing only on SNPs.

    Abstract : Som examensarbete på skogsmästarprogrammet har en studie genomförts som syftar till att göra en uppföljning på ett antal av Sveaskogs skogssådder. Trakterna som inventerades gällande återbeskogning var geografiskt spridda runt Skinnskatteberg och sådda åren 2018, 2019 och 2020. READ MORE

  5. 4. Evaluation of the forest composition in browsed Scots pine plantations

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Carl Noyce; [2022]
    Keywords : browsing damage; forest owners; mera tall; moose; pine regeneration; Södra;

    Abstract : Since the early 2000s browsing damage to Scots pine (Pinus Sylvestris) in the Götaland region of Sweden has been consistently estimated to be 15% per year, peaking at around 25% between 2009-2016, the highest of any region in the country. The Swedish Forest Agency has set a goal of achieving pine damage levels below 5% on average in the long-term, even if higher levels can be accepted in an individual year. READ MORE

  6. 5. The land carbon sink of Lithuanian forests in the light of climate change: A model approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Patricija Marijauskaite; [2022]
    Keywords : Geography; Physical geography; Ecosystem analysis; Ecosystem modelling; LPJ-GUESS; Climate change; Forest sequestration; Land carbon sink; Norway spruce; Scot s pine; Silver birch; monoculture; silviculture; NPP; NBP; Earth and Environmental Sciences;

    Abstract : Forests form the backbone of the European terrestrial carbon sink (State Forest Service & Ministry of Environment, 2018). As the European Union (EU) strives to become climate neutral by 2050, forests are accounted for the natural carbon absorption mechanism (European Commission, n.d.). READ MORE
