Causes and consequences of soil carbon mobilization and lake brownification in northern forested landscapes
… as dissolved organic matter and causing the brownification of lakes. This thesis investigated the causes of soil carbon destabilization and consequences of the mobilized soil carbon to lake food webs. The first finding was that global change increased carbon export from catchments. Increased …

Dissolved organic matter dynamics in diverse freshwater ecosystems across Canada: long-term trends, transformations, and explanatory factors
… The increase in DOC concentrations, known as brownification, has drawn considerable attention due to its implications for ecosystem dynamics. While past studies have documented the influence of recovery from acidification and climate change on long-term DOC trends, the emerging importance of …

Carbon gains, losses, and feedbacks in shallow, eutrophic lakes of phytoplankton and macrophyte dominance
Lakes are increasingly being recognized as an important component of the global carbon cycle, yet anthropogenic activities that alter their community structure may change the way they transport and process carbon. This research focuses on the relationship between carbon cycling and community …

A palaeolimnological study of the anthropogenic impact on dissolved organic carbon in South Swedish lakes
During the past three decades, increases have been observed in dissolved organic carbon (DOC) concentrations and colour in the surface waters of lakes and rivers in parts of Europe and North America, raising concern about the effects on the quality of aquatic environments with consequences for …
