We describe the general background and the recent advances in research on underwater
photosynthesis of leaf segments, whole communities, and plant dominated aquatic …

HT Odum's influential Limnology and Oceanography 1956 publication compared gross
primary production (GPP) and ecosystem respiration (ER) among aquatic ecosystems. Few …

The eutrophication of lowland lakes in Europe by excess nitrogen (N) and phosphorus (P) is
severe because of the long history of land‐cover change and agricultural intensification. The …

The precipitation of carbonate minerals does not invariably result in CO 2 emission to the
atmosphere, because dissolved inorganic carbon (DIC) can be partially utilized by terrestrial …

Metabolism is a fundamental process in ecosystems that crosses multiple scales of
organization from individual organisms to whole ecosystems. To improve sharing and reuse …

The measurement of stream metabolism (gross primary production and respiration) has
become more feasible with the availability of more reliable dissolved oxygen (DO) probes …

Climate warming is expected to have large effects on ecosystems in part due to the
temperature dependence of metabolism. The responses of metabolic rates to climate …

Here we present direct measurements of the biological breakdown of 13C‐labeled
substrates to CO2 at seven locations along the lower Amazon River, from Óbidos to the …

Net ecosystem production (NEP) and the overall organic carbon budget for the estuaries
along the East Coast of the United States are estimated. We focus on the open estuarine …

Transport and transformation of inorganic nutrients are influenced by abiotic-biotic
interactions and determine downstream water quality. Macrophytes play an important role in …
