Northern ecosystems are experiencing some of the most dramatic impacts of global change
on Earth. Rising temperatures, hydrological intensification, changes in atmospheric acid …

Many freshwater systems receive substantial inputs of terrestrial organic matter. Terrestrially
derived dissolved organic carbon (t‐DOC) inputs can modify light availability, the spatial …

Bacteria play a central role in the cycling of carbon, yet our understanding of the relationship
between the taxonomic composition and the degradation of dissolved organic matter (DOM) …

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 …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

Inland waters transport large amounts of dissolved organic matter (DOM) from terrestrial
environments to the oceans, but DOM also reacts en route, with substantial water column …

Productivity denotes the rate of biomass synthesis in ecosystems and is a fundamental
characteristic that frames ecosystem function and management. Limitation of productivity by …

Although the study of resource subsidies has emerged as a key topic in both ecosystem and
food web ecology, the dialogue over their role has been limited by separate approaches that …

Water browning or brownification refers to increasing water color, often related to increasing
dissolved organic matter (DOM) and carbon (DOC) content in freshwaters. Browning has …

Understanding how ecosystems store or release carbon is one of ecology's greatest
challenges in the 21st century. Organic matter covers a large range of chemical structures …
