  1. 1. A computational model of metapopulation dynamics and organism-mediated nutrient flow

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Amanda Hansson; [2023-08-07]
    Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

    Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

  3. 2. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    University essay from SLU/Dept. of Ecology

    Author : Marta Holmlund; [2023]
    Keywords : wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Abstract : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

  4. 3. Identification of restoration hotspots in landscape-scale green infrastructure planning based on model-predicted connectivity forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Xiaoming Wang; [2023]
    Keywords : boreal forest; conservation; restoration; connectivity; green infrastructure; GIS; Sweden; Earth and Environmental Sciences;

    Abstract : Boreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. READ MORE

  6. 5. Carabidocoenoses and Fragments of Forests : exploring the Carabid Landscape

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

    Author : Simon Heinrich Arns; [2023]
    Keywords : biodiversity; Carabidae; carabid diversity; entomology; Fragmentation; Fragstats; habitat fragmentation; habitat Heterogeneity; landscape; landscape ecology; landscape Heterogeneity; pitfall trap; quantifying fragmentation;

    Abstract : Epigeic ground beetles (Coleoptera: Carabidae) were sampled between 2021-06-28 and 2021-07-09 using pitfall traps in the Swedish counties Värmland and Gävleborg. The structural properties of the landscapes surrounding these points were estimated from the Swedish Environmental Protection Agency’s national land cover databases and the Swedish Forest Agency’s data for all formally protected and high conservation value forests using patch-based configurational metrics.
