1. A computational model of metapopulation dynamics and organism-mediated nutrient flow
University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskapAbstract : 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.

2. Går det att skapa lekdammar till salamandrar? : en utvärdering av naturvårdsåtgärder för större vattensalamander i Uppsala län
University essay from SLU/Dept. of EcologyAbstract : Våra svenska groddjursarters utbredning hotas av att småvattenlandskapen minskar till följd av igenväxning, exploatering och fragmentering. Groddjur är helt beroende av mindre dammar för att reproducera sig, men kräver även ett passande landhabitat. READ MORE

3. Spatiotemporal Fidelity of a Metapopulational Model Evaluated on the COVID-19 Pandemic in Sweden
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : A modified SEIR compartmental model is constructed for COVID-19 in a metapopulational setting with fine-scaled population data. The model is stochastically simulated with GLEAMviz that provides realistic short and long distance mobility based on real-world data. READ MORE

4. How do corridors connecting two separated landscapes affect the ability of trophic metacommunities to survive habitat loss?
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : With an increasing worldwide infrastructure more habitats are fragmented by roads and buildings, which can cause a reduction in biodiversity up to 75%. One way to counteract this is by predicting the outcome, with the help of theoretical models, before it happens. READ MORE

5. Pedigree reconstruction reveals large scale movement patterns and population dynamics of wolverines (Gulo gulo) across Fennoscandia
University essay from SLU/Dept. of Wildlife, Fish and Environmental StudiesAbstract : Dispersal is a biological imperative for many species, facilitating gene flow and influencing population dynamics. Modern landscapes are increasingly fragmented, leaving species that rely on dispersal trapped in ever shrinking areas. READ MORE
