1. Stable chlorine isotope analysis of chlorinated acetic acids
Sammanfattning : Chlorinated acetic acids (CAAs) constitute a group of polar organic compounds that are ubiquitous in the environment. Their environmental occurrence has been extensively studied but their sources are still not well constrained. LÄS MER
2. Early Pottery Use among Hunter-Gatherers around the Baltic Sea
Sammanfattning : This thesis aims to provide an understanding of the dynamics underlying the adoption of pottery by pre-agrarian hunter-gatherer cultural groups around the Baltic Sea. The focus is on three approximately contemporaneous early pottery traditions of the region (ca. LÄS MER
3. Intramolecular isotope analysis reveals plant ecophysiological signals covering multiple timescales
Sammanfattning : Our societies' wellbeing relies on stable and healthy environments. However, our current lifestyles, growth-oriented economic policies and the population explosion are leading to potentially catastrophic degradation of ecosystems and progressive disruption of food chains. LÄS MER
4. Towards understanding stable isotope signatures in stressed systems
Sammanfattning : Stable isotope analysis (SIA) is a valuable tool in ecotoxicology because δ13C and δ15N may provide insights into the trophic transfer of contaminants in a food web. The relationship between a species’ trophic position (TP, determined from δ15N) and internal concentration of biomagnifying contaminants can be established and used for regulatory purposes. LÄS MER
5. The functional potential of methane producing and consuming microorganisms in a changing world : Den funktionella potentialen hos mikroorganismer som producerar och förbrukar metan i en föränderlig värld
Sammanfattning : It’s clear that human activities have heated our climate via the release of anthropogenic greenhouse gases. Recent changes within the earth climate are rapid, intensifying, and unprecedented. LÄS MER
