11. Type 1 diabetes in pregnancy : perinatal outcome with special reference to fetal macrosomia
Sammanfattning : The aim of this epidemiological study was to elucidate whether in recent years, obstetric and perinatal outcomes in pregnancies complicated by type 1 diabetes (T1DM) have improved or not. The objective was also to identify possible risk factors for adverse outcome for the mother, fetus and the newborn. LÄS MER
12. Evolutionary consequences of sex-specific selection
Sammanfattning : Sex-specific selection is widespread, evident by the evolution of sexual dimorphism in many traits in sexually reproducing taxa. The reason why the sexes may experience selection that differs in direction or magnitude is often linked to the reproductive strategies associated with the sex-specific reproductive physiology.

13. Biogeochemical evidences of human intervention in a shallow lake, Zeekoevlei, South Africa
Sammanfattning : This thesis describes a multi-parameter biogeochemical investigation in a shallow hyper-eutrophic freshwater coastal lake, Zeekoevlei, in South Africa. The predominance of autochthonous algal-derived organic matter in lake sediments is indicated by low C/N, high H/C ratios and δ13Corganic values. LÄS MER
14. Implications of land use on the carbon cycle - Impacts of long-term human activities on terrestrial organic matter input to aquatic ecosystems in southern Sweden
Sammanfattning : Human activities have a huge impact on the carbon cycle by modifying the landscape. Vegetation cover changes attributed to forest clearance and the expansion of agricultural land increases soil erosion, organic matter and other nutrient delivery from terrestrial to aquatic ecosystems.

15. Zooplankton growth and trophic linkages : Implications for fish feeding conditions in the Baltic Sea
Sammanfattning : The aim of this Thesis was to improve our understanding and assessment of feeding conditions for zooplanktivorous fish in the Baltic Sea.We investigated (papers I, II) the usefulness of biochemical proxies for assessments of growth and metabolic rates in the dominant Baltic copepod Acartia bifilosa.
