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

Depicted as large polymers by the traditional model, humic substances (HS) tend to be
considered resistant to biodegradation. However, HS should be regarded as …

We explore the role of lakes in carbon cycling and global climate, examine the mechanisms
influencing carbon pools and transformations in lakes, and discuss how the metabolism of …

While there is a general sense that lakes can act as sentinels of climate change, their
efficacy has not been thoroughly analyzed. We identified the key response variables within a …

Communities of microscopic plant life, or phytoplankton, dominate the Earth's aquatic
ecosystems. This important new book by Colin Reynolds covers the adaptations, physiology …

A better understanding is needed of how hydrological and biogeochemical processes
control dissolved organic carbon (DOC) concentrations and dissolved organic matter (DOM) …

Humic substances (HS), a highly transformed part of non-living natural organic matter
(NOM), comprise up to 70% of the soil organic matter (SOM), 50–80% of dissolved organic …

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 …

Iron is a source of interference in the spectroscopic analysis of dissolved organic matter
(DOM); however, its effects on commonly employed ultraviolet and visible (UV–vis) light …

Although prokaryotes are small in size, they are a significant biomass component in aquatic
planktonic ecosystems and play a major role in biogeochemical processes. A review of the …
