1. POSSIBLE TIMING OF THE TRANSITION FROM PRE-INDUSTRIAL TO INDUSTRIAL CLIMATE IN THE CENTRAL TO NORTHERN OF SWEDEN, BASED ON PROXY DATA FROM TREE-RINGS
Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaperSammanfattning : Earth’s climate has varied through time, with orbital forcing as the most dominant force on the climate system the last million years, causing glacial-interglacial cycles. The last glacial period ended about 11.6 thousand years (kyr), ago and the last interglacial maximum around 6.5 kyr ago. LÄS MER
2. Demography of Birch Populations across Scandinavia
Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Boreal forests are particularly vulnerable to climate change, experiencing a much more drastic increase in temperatures and having a limited amount of more northern refugia. The trees making up these vast and important ecosystems already had to adapt previously to environmental pressures brought about by the repeated glaciations during past ice ages. LÄS MER
3. Population genetic analyses inform conservation of the endangered Clouded Apollo (Parnassius mnemosyne) butterfly in Sweden
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The clouded apollo (Parnassius mnemosyne) is a palearctic butterfly with a wide distribution across Eurasia. In recent decades, however, the species has declined in many parts of its distribution range. LÄS MER
4. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. LÄS MER
5. Investigating the Magnetic Susceptibility of Cornish Loess as a Tool for Understanding the Palaeoclimate of SW England
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Loess is a silty material produced via glacial grinding and its deposition is usually associated with colder periods when there is a considerable increase in atmospheric dust transport. The magnetic susceptibility of loess-palaeosol sequences has been the subject of extensive research within palaeoclimatology as it has proven to be reliable climate proxy. LÄS MER
