Crossing a critical threshold: Accelerated and widespread land use changes drive recent carbon and nitrogen dynamics in Vichuquén Lake (35°S) in central Chile
(Elsevier B.V., 2021)
© 2021 Elsevier B.V.Global afforestation/deforestation processes (e.g., Amazon deforestation and Europe afforestation) create new anthropogenic controls on carbon cycling and nutrient supply that have not been fully assessed. ...
Stable isotopes of bulk organic matter to trace carbon and nitrogen dynamics in an estuarine ecosystem in Babitonga Bay (Santa Catarina, Brazil)
(ELSEVIER SCIENCE BV, 2010)
The biogeochemical processes affecting the transport and cycling of terrestrial organic carbon in coastal and transition areas are still not fully understood One means of distinguishing between the sources of organic ...
Long-term grazing negatively affects nitrogen dynamics in Northern Patagonian wet meadows
(Elsevier, 2014-10)
Wet meadows are seasonally saturated wetlands that can develop in arid and semi-arid areas. In the semi-arid region of North Patagonia, Argentina wet meadows are islands of high net primary productivity surrounded by low ...
Inibidor de nitrificação adicionado ao solo com cama de aviário e sua influência na dinâmica do nitrogênio e do carbono
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2012-08-31)
Nitrification inhibitors can reduce the potential for environmental contamination of animal
wastes, relatively to nitrate (NO3
-) leaching and nitrous oxide (N2O) emission. However, this
strategy has not yet been ...
Theoretical studies on electron-carbon monoxide collisions in the low and intermediate energy range
(Elsevier Science BvAmsterdamHolanda, 2002)
Carbon and nitrogen dynamics in a sandy groundwater-coupled ecosystem in the Monte Desert, indicated by plant stable isotopes
(Elsevier, 2014-01)
The high productivity of sandy groundwater-coupled woodlands in the Monte Desert is exploited by local pastoralist communities for fuel, domestic use, and manure accumulation and export to irrigated oases. We explored ...
Carbon (δ13C) and nitrogen (δ15N) stable isotope composition in plant and soil in Southern Patagonia’s native forests.
(Wiley, 2012-01)
Stable isotope natural abundance measurements integrate across several biogeochemical processes in ecosystem N and C dynamics. Here, we report trends in natural isotope abundance (d13C and d15N in plant and soil) along a ...
Effect of organic nitrogen and carbon mineralization on sediment organic matter accumulation in fish ponds
(Aquaculture Research, 2005-07-01)
In aquaculture, ponds with high loads of organic inputs, organic matter accumulates at the bottom over time. Uneaten feed, senescent phytoplankton and faeces are the principal sources of accumulated material, but quanti¢cations ...
SIMULATION OF USE AND MANAGEMENT EFFECTS ON THE SOIL ORGANIC MATTER POOLS OF THE ATLANTIC FOREST BIOME, BRAZIL
