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 ...
Agriculture impairs stream ecosystem functioning in a tropical catchment
(Elsevier B.V., 2020)
Growth and cytometric diversity of bacterial assemblages under different top-down control regimes by using a size-fractionation approach
(Oxford University Press, 2018-03)
Zooplankton communities in tropical inland waters are generally characterized by small bodied individuals and the absence of large daphnids. However, the effects of this peculiar food web configuration on microbial ...
Environmental dynamics as a structuring factor for microbial carbon utilization in a subtropical coastal lagoon
(Frontiers, 2013-02)
Laguna de Rocha belongs to a series of shallow coastal lagoons located along South America. It is periodically connected to the sea through a sand bar, exhibiting a hydrological cycle where physicochemical and biological ...
Recording of climate and diagenesis through sedimentary DNA and fossil pigments at Laguna Potrok Aike, Argentina
(Copernicus Publications, 2016-04)
Aquatic sediments record past climatic conditions while providing a wide range of ecological niches for microorganisms. In theory, benthic microbial community composition should depend on environmental features and geochemical ...
Microbial eukaryotes assemblages and potential novel diversity in four tropical East-African Great Lakes
(Wiley Blackwell Publishing, Inc, 2021-08-02)
East African Great Lakes are old and unique natural resources heavily utilized by their bordering countries. In those lakes, ecosystem functioning is dominated by pelagic processes, where microorganisms are key components; ...
Jellyfish Life Stages Shape Associated Microbial Communities, While a Core Microbiome Is Maintained Across All
(Frontiers Media, 2018-07-12)
The key to 650 million years of evolutionary success in jellyfish is adaptability: with alternating benthic and pelagic generations, sexual and asexual reproductive modes, multitudes of body forms and a cosmopolitan ...
Primary production and plankton assemblages in the fisheries ground around San Jorge Gulf (Patagonia) during spring and summer
(Plankton Society of Japan, 2021-02-19)
The San Jorge Gulf, and the littoral to its north, is one of the most important fishing grounds for Argentina. Nevertheless, phytoplankton production has been scarcely studied. Here we analyzed during spring (2008) and ...
Incorporation of inorganic mercury (Hg2+) in pelagic food webs of ultraoligotrophic and oligotrophic lakes: The role of different plankton size fractions and species assemblages
(Elsevier Science, 2014-08)
In lake food webs, pelagic basal organisms such as bacteria and phytoplankton incorporate mercury (Hg2+) from the dissolved phase and pass the adsorbed and internalized Hg to higher trophic levels. This experimental ...
Molecular characterization of microbial populations in a low grade copper ore bioleaching test heap
(ELSEVIER SCIENCE BV, 2005)
A culture-independent approach based on PCR amplification and denaturing gradient gel electrophoresis (DGGE) and sequencing of 16S rRNA gene fragments from both Bacteria and Archaea were used to analyze the microbial ...
