d13C tracing of dissolved inorganic carbon sources in Patagonian rivers (Argentina) [PDF]

open access: yes, 2005
The main Patagonian rivers (Colorado, Negro, Chubut, Deseado, Coyle, Chico, Santa Cruz and Gallegos) were sampled between September 1995 and November 1998 to determine their chemical and isotopic compositions, the origins of the suspended and dissolved ...

Methane- and dissolved organic carbon-fueled microbial loop supports a tropical subterranean estuary ecosystem

open access: yesNature Communications, 2017
Subterranean estuaries extend inland into density-stratified coastal carbonate aquifers containing a surprising diversity of endemic animals (mostly crustaceans) within a highly oligotrophic habitat.

Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]

open access: yes, 2011
Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Microbial Interactions With Dissolved Organic Matter Drive Carbon Dynamics and Community Succession

open access: yesFrontiers in Microbiology, 2018
Knowledge of dynamic interactions between natural organic matter (NOM) and microbial communities is critical not only to delineate the routes of NOM degradation/transformation and carbon (C) fluxes, but also to understand microbial community evolution ...

A new conceptual framework for the transformation of groundwater dissolved organic matter

open access: yesNature Communications, 2022
Groundwater comprises 95% of the liquid fresh water on Earth and contains a diverse mix of dissolved organic matter (DOM) molecules which play a significant role in the global carbon cycle.

Short-term fate of phytodetritus in sediments across the arabian sea oxygen minimum zone [PDF]

open access: yes, 2007
The short-term fate of phytodetritus was investigated across the Pakistan margin of the Arabian Sea at water depths ranging from 140 to 1850 m, encompassing the oxygen minimum zone (~100–1100 m).

Distribution of Organic Carbon in the Sediments of Xinxue River and the Xinxue River Constructed Wetland, China. [PDF]

open access: yesPLoS ONE, 2015
Wetland ecosystems are represented as a significant reservoir of organic carbon and play an important role in mitigating the greenhouse effect. In order to compare the compositions and distribution of organic carbon in constructed and natural river ...

Oxygen, carbon, and nutrients in the oligotrophic eastern subtropical North Atlantic [PDF]

open access: yes, 2010
The Beta Triangle, a region of the oligotrophic subtropical eastern North Atlantic Ocean, is notorious for its enigmatic oxygen, carbon, and nitrogen balances, in which nutrient supply is said to explain only a fraction of production necessary for ...

Predator‐induced changes in dissolved organic carbon dynamics [PDF]

open access: yesOikos, 2018
The fate of dissolved organic carbon (DOC) is partly determined by its availability to microbial degradation. Organisms at upper trophic levels could influence the bioavailability of DOC via cascading effects on primary producers and bacteria. Here we experimentally tested whether the presence of fish in aquatic food webs can indirectly affect the ...
