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 ...
Factors influencing the characteristics and distribution or surface organic matter in the Pacific-Atlantic connection
(Elsevier Science, 2017-11)
The present work reports the first data set on particulate organic carbon (POC) and nitrogen (PON), and the high-resolution modelling of their stable isotope variability in the Patagonian Cold Estuarine System (PCES), with ...
Estoque de carbono em plantações de Eucalyptus sp. implantados em campo nativo
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2009-03-03)
The soil management with emphasis in keeping soil residues on surface combined with vegetation growth may reduce carbon (C) emission to the atmosphere. The objective of this study is to measure the effects of the Eucaliptus ...
Sedimentation rates of nutrients and particulate material in pond mariculture of shrimp (Litopenaeus vannamei) carried out with different management strategies
(2021-03-15)
Marine shrimp farming is an important economic activity in tropical and subtropical regions, but its expansion has contributed to the increase of nutrients and organic matter in coastal ecosystems. Thus, this work evaluated ...
High particulate iron(II) content in glacially sourced dusts enhances productivity of a model diatom
(American Association for the Advancement of Science, 2017-06)
Little is known about the bioavailability of iron (Fe) in natural dusts and the impact of dust mineralogy on Fe utilization by photosynthetic organisms. Variation in the supply of bioavailable Fe to the ocean has the ...
Winter cover crops in soybean monoculture: effects on soil organic carbon and its fractions
(2016-08)
The current agricultural production systems in the Pampas Region have been significantly simplified by cultivating large land areas under no tillage (NT), where soybean is the predominant crop. These systems with long ...
Stabilization of new carbon inputs rather than old carbon decomposition determines soil organic carbon shifts following woody or herbaceous vegetation transitions
(Springer, 2016-12)
Background and aims:
Although numerous studies have quantified the effects of land-use changes on soil organic carbon (SOC) stocks, few have examined simultaneously the weight of carbon (C) inputs vs. outputs in shaping ...
Fluvial organic carbon cycling regulated by sediment transit time and mineral protection
(Nature Publishing Group, 2021-11)
Rivers transfer terrestrial organic carbon (OC) from mountains to ocean basins, playing a key role in the global carbon cycle. During fluvial transit, OC may be oxidized and emitted to the atmosphere as CO2 or preserved ...
Comparison of indoor and outdoor air quality in latino communities in Peru, Chile, and USA
(International Society of Indoor Air Quality and Climate, 2015)
The air quality inside and outside the homes of three Latino communities (rural Peru, urban Chile and suburban USA) was compared in this study. Filter samples were collected and analysed for fine mass (PM2.5) and elemental ...
