Extração de matéria orgânica aquática por abaixamento de temperatura: Uma metodologia alternativa para manter a identidade da amostra
(2003-03-01)
In this work was developed an alternative methodology to separation of aquatic organic matter (AOM) present in natural river waters. The process is based in temperature decreasing of the aqueous sample under controlled ...

TILLAGE EFFECT ON SOIL ORGANIC MATTER, MYCORRHIZAL HYPHAE AND AGGREGATES IN A MEDITERRANEAN AGROECOSYSTEM
(Sociedad Chilena de la Ciencia del Suelo, 2010)
Quantificação das bactérias sólido-aderidas, bactérias e protozoários líquido-associados do rúmen de bovinos jovens alimentados com amiréia
(2002-03-01)
It were utilized four crossbreed, castrated, rumen cannuladed bovines, receiving dietary starea (containing 30% of urea) in the concentrate and corn silage, with the objective of quantify the liquid-associated bacteria and ...
Benthic responses to organic matter variation in a subtropical coastal area off SE Brazil
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
Organic matter quality, expressed as the proportion of chlorophyll a (Chl a) to degraded organic material (i.e. phaeopigments), is known to influence the structure of benthic associations and plays an important role in the ...
Plant rhizodeposition: A key factor for soil organic matter formation in stable fractions
(Science Advances is the American Association for the Advancement of Science, 2021-04)
Soil organic carbon formation remains poorly understood despite its importance for human livelihoods. Uncertainties remain for the relative contributions of aboveground, root, and rhizodeposition inputs to particulate (POC) ...
Calcareous benthic foraminifera from the upper central peruvian margin: Control of the assemblage by pore water redox and sedimentary organic matter
(Inter Research, 2015)
We studied 'living' (stained) benthic foraminifera in the upper border of the Peruvian oxygen minimum zone (OMZ) to determine the relationship between species' distribution and pore water and sediment geochemistry under ...
Seasonal patterns of organic matter stoichiometry along a mountain catchment
(Springer, 2016-05)
Organic matter (OM) nutrient content is expected to change as OM is transported from upstream forested reaches downstream to open land, and these changes could depend on seasonal patterns. The aim of this study was to ...
