  1. 1. Riparian forests : a comparison of tree diversity, deadwood and canopy cover between primary and production riparian forests along headwaters

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

    Author : Eric Lundqvist; [2022]
    Keywords : riparian forest; primary forest; production forest; tree diversity; deadwood; canopy cover;

    Abstract : Headwaters and their adjacent riparian forests (RF) have been recognized for years for their tight interlinkage and essential ecological and biogeochemical services. Notwithstanding, headwaters in Sweden have historically been overlooked in forest management, which has led to conifer-dominated RFs with simplified even-age structure. READ MORE

  2. 2. A detailed study on Amazon Forest structure and mortality rates through LPJ-GUESS vegetation model

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sara Mazzuoli; [2021]
    Keywords : Amazon s Forest; LPJ-GUESS; simulation; TEAM-NETWORK; dynamic vegetation model; observation; mortality; allometry; tree stand structure; biomass; cohort; PFTs; plant functional types; NPP; Earth and Environmental Sciences;

    Abstract : Nowadays it has become relevant for scientists to understand the impact of tropical forest structure on the Global Carbon Cycle. Dynamic vegetation models have been developed to pursue this issue, specifically by improving algorithms that could analyze the allometry, biomass content and mortality rate of each singular simulated plant individual and how this responds to climate change, management and rising CO2 concentrations.

  3. 3. Stand Structure in a Heterogeneous Old-growth Norway Spruce (Picea abies (L.) Karst.) Forest in Northern Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Sara Jäger; [2020-11-19]
    Keywords : ;

    Abstract : This study investigate the growth trend in an unmanaged Norway spruce forest in Västerbotten Country, Sweden. The result indicate that relationship between the diameter at breast height (1.3 m) and height follow a statistical significant trendline, where taller trees also represent wider tree diamater.

  4. 4. Nocturnal moths use of novel habitats : a case study on a power line in a forest-mire mosaic in boreal Sweden

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Oskar Lövbom; [2020]
    Keywords : pollinators; Lepidoptera; moth; transmission line; assemblage structure; Noctuoidea; Geometridae;

    Abstract : Biodiversity and pollinators are declining all over the world, and a factor thought to cause this decline is destruction of natural habitats. One new way that has been discussed in an effort to try to mitigate the effects of declining habitats is to understand and use novel habitats, which are habitats created when, for example, building roads, railways, and power lines.

  5. 5. Bladyta och virkesproduktion i fullskiktad granskog skött med blädningsbruk

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

    Author : Elin Edman; [2019]
    Keywords : bladyteindex; gran; blädningsbruk; ljusinsläpp; virkesproduktion; hyggesfritt skogsbruk; Leaf Area Index; Norway spruce; single-tree selection system; light penetration; volume growth; continous cover forestry;

    Abstract : I dagens samhälle har klimatförändringarna tagit en allt större plats i den politiska debatten, vilket har resulterat i att det numera är många olika värden som är viktiga att ta hänsyn till i skogsbruket förutom virkesproduktion. Samhället vill ha en större variation inom skogsskötseln och en ökad användning av hyggesfria skötselmetoder. READ MORE
