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 ...
Effects of polyphenols on plankton assemblages and bacterial abundance representative of a pampean shallow lake: an experimental study
(Inter-Research, 2020-10-08)
Shallow lakes are complex environments that play an important role in ecology. Their relationships with the surrounding areas make these lentic water bodies susceptible to alterations in response to human activity. For ...
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 ...
Planktonic foraminifera assemblages from the Brazil–Malvinas Confluence: palaeoceanographic implications of sub-surface temperature reconstructions in the western South Atlantic
(Wiley Blackwell Publishing, Inc, 2021-02)
Planktonic foraminifera census data have been widely used to reconstruct changes in ocean ecosystems as well as ocean chemistry and circulation through calibration functions. Here we analyse new core-top census data from ...
Precipitation patterns, dissolved organic matter and changes in the plankton assemblage in Lake Escondido (Patagonia, Argentina)
(Springer, 2012-07-27)
Global warming affects the hydrological cycle by increasing the frequency and intensity of extreme rainfall events and dry spells. These changes potentially affect the quantity and quality of dissolved organic matter (DOM) ...
Drivers of highly diverse planktonic ciliate assemblages in peat bog pools from Tierra del Fuego (Argentina)
(Springer, 2016-02)
Peatlands often encompass shallow pools, wherein dystrophic and colored acid waters host a remarkably diverse biota, with ciliates likely playing a key role in their short trophic webs. In the Sphagnum magellanicum-dominated ...
Highly diverse planktonic ciliate assemblages characterize minerotrophic and ombrotrophic pools from a Fuegian peat bog (Argentina)
(Springer, 2016-06)
Peatlands often encompass shallow pools, wherein dystrophic and colored acid waters host a remarkably diverse biota, with ciliates likely playing a key role in their short trophic webs. In the Sphagnum magellanicum-dominated ...
Depths, paleodepths and the percentage of foraminiferal assemblages comprising planktonics in Trinidad
(Centro de Ciências Matemáticas e da Natureza, Instituto de Geociências, Universidade Feder, 2006)
Top-down effects of an exotic serpulid polychaete on natural plankton assemblage of estuarine and brackish systems in the SW Atlantic
(Coastal Education & Research Foundation, 2014-11)
The invasive reef-building polychaete Ficopomatus enigmaticus (Fauvel, 1923) has become well-established in many temperate brackish waters. To analyze preferences for different planktonic food sources, short-term (~1.5 h), ...
Foraminíferos planctônicos do Paleoceno no testemunho DSDP site 356, platô de São Paulo, Atlântico Sul: bioestratigrafia e inferências paleoecológicas
(Universidade do Vale do Rio dos Sinos, 2016-07-29)
The Paleocene is characterized by an interval that succeeds the K-Pg mass extinction event which affected several fossil groups. In its study reveals not only a sequential pattern of evolutionary radiation but also processes ...
