Assessment of the impacts of shallow gas on taxonomic structure of benthic communities in Bahía Blanca estuary (Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2020-10-05)
Shallow biogenic gas deposits located in the surface of the seabed may affect abundance, diversity, biomass and structure of benthic communities. Nevertheless, the magnitude and responsible variables of this effect still ...
Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
(Elsevier, 2021-12)
It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ...
Distribution and isotopic signature of deep gases in submerged soils in an island of the Lower Delta of the Paraná River, Argentina
(Springer, 2018-10)
AbstractSubsoil CH4 and CO2concentrations, δ13C-CH4 and δ13C-CO2 signatures, total organic carbon (TOC) and δ13 C-TOC, together with C/N ratio of organic matter , were evaluated throughout a soil profile up to the atmosphere ...
A fractal-like kinetics equation to calculate landfill methane production
(Elsevier, 2004-01)
Landfill appears as a convenient choice to get rid of municipal solid waste while providing energy, due to methane generated through anaerobic fermentation. However, without capture and treatment landfill gas is considered ...
Assessment of Biological Contribution to Natural Recovery of Anthropized Freshwater Sediments From Argentina: Autochthonous Microbiome Structure and Functional Prediction
(Frontiers Media, 2021-03)
Monitored natural recovery (MNR) is an in situ technique of conventional remediation for the treatment of contaminated sediments that relies on natural processes to reduce the bioavailability or toxicity of contaminants. ...
Zero to moderate methane emissions in a densely rooted, pristine Patagonian bog - biogeochemical controls as revealed from isotopic evidence
(Copernicus Publications, 2019-01)
Peatlands are significant global methane (CH4) sources, but processes governing CH4 dynamics have been predominantly studied on the northern hemisphere. Southern hemispheric and tropical bogs can be dominated by cushion ...
A review of plant-derived essential oils in ruminant nutrition and production
(Elsevier Science, 2008-08)
Public concern over use of antibiotics in livestock production has increased in recent years because of their possible contribution to emergence of antibiotic resistant bacteria, and their transmission from livestock to ...
Southern Hemispheric Westerlies control sedimentary processes of Laguna Azul (south-eastern Patagonia, Argentina)
(Sage Publications Ltd, 2019-03)
Multiproxy investigations of lacustrine sediments from Laguna Azul (52 °S) document multi-millennial Holocene influences of Southern Hemispheric Westerlies (SHW) on the hydroclimatic variability of south-eastern Patagonia. ...
