The Arctic is a water-rich region, with freshwater systems covering about 16% of the northern
permafrost landscape. Permafrost thaw creates new freshwater ecosystems, while at the …

Dissolved organic carbon (DOC) concentrations in lakes are changing globally, but little is
known about potential ecosystem impacts. We evaluated the relationship between DOC and …

Abstract “Phytoplankton” is a loosely defined functional term, indicating a group of
organisms distributed into several taxonomic groups ranging from oxygenic photosynthetic …

Abstract The Western Siberia Lowland (WSL), the world's largest permafrost peatland, is of
importance for understanding the high-latitude carbon (C) cycle and its response to climate …

We assembled data from a global network of automated lake observatories to test
hypotheses regarding the drivers of ecosystem metabolism. We estimated daily rates of …

Invisible to the naked eye lies a tremendous diversity of organic molecules and organisms
that make major contributions to important biogeochemical cycles. However, how the …

Global change is altering the vast amount of carbon cycled by microbes between land and
freshwater, but how viruses mediate this process is poorly understood. Here, we show that …

This study examines a natural, rapid, fivefold increase in dissolved organic carbon (DOC)
concentrations in a temperate shallow lake, describing the processes by which increased …

Elevated allochthonous inputs of organic matter are increasingly recognized as a driver of
ecosystem change in lakes, particularly when concurrent with eutrophication. Evaluation of …

Lakes are a major component of boreal landscapes, and whereas lake CO 2 emissions are
recognized as a major component of regional C budgets, there is still much uncertainty …
