1. The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)
Abstract : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.

2. On the Late Saalian glaciation : A climate modeling study
Abstract : This thesis focuses on the glaciation of the Late Saalian period (160 -140 ka) over Eurasia. The Quaternary Environment of the Eurasian North (QUEEN) project determined that during this period, the Eurasian ice sheet was substantially larger than during the entire Weichselian cycle and especially that of the Last Glacial Maximum (21 ka, LGM).

3. Influence of solar activity and environment on 10Be in recent natural archives
Abstract : Understanding the link between the Sun and climate is vital in the current incidence of global climate change, and 10Be in natural archives constitutes an excellent tracer for this purpose. As cosmic rays enter the atmosphere, cosmogenic isotopes like 10Be and 14C are formed. READ MORE

4. Benthic environmental responses to climatic changes during the late Quaternary: a micropalaeontological and geochemical approach
Abstract : There is a limited understanding of how the benthic environment within upwelling regions responded to past rapid climatic changes. Within this thesis, a multiproxy approach is applied to two marine sediment cores from two coastal upwelling sites in the low latitude subtropical Atlantic. READ MORE

5. Molluscs, Environment and Man - A Bioarchaeological Approach in Sweden
Abstract : The thesis aims to examine the role and use of molluscs in Swedish prehistory, in chorological and chronological aspects. Molluscs live in the sea, fresh water and on land. The Swedish mollusc fauna contains 623 taxa: 417 marine, 85 limnic and 121 terrestrial species. READ MORE
