1. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

2. Feasibility of reintroduction of European Bison (Bison bonasus) to Sweden with focus on traffic accidents
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : The historical occurrence of European bison (Bison bonasus) in Sweden during the early Holocene emphasizes the ecological significance for a potential reintroduction. The European bison, the largest herbivore on the European continent, is a keystone species with a significant influence on ecosystem dynamics. LÄS MER
3. Granens ankomst och etablering i Skandinavien under postglacial tid
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Att förstå hur vegetation reagerar på klimatförändringar är viktigt av flera skäl, inte minst eko-nomiska när det gäller träd som är betydelsefulla för skogsbruket såsom gran (Picea abies) och tall (Pinus Sylvest-ris). För att förstå detta behövs kunskap om de mekanismer som ligger bakom trädarternas respons på förändringar i deras levnadsmiljö, vilket man kan få från paleoekologisk forskning baserad på pollenanalyser, aDNA-analyser och makrofossilanalyser.

4. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. LÄS MER
5. Land cover changes in Southern Sweden from the mid-Holocene to present day: insights for ecosystem service assessments
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from pollen information.
