The significance of modern diatoms as paleoenvironmental indicators along an altitudinal gradient in the Andean piedmont of central Argentina
(Elsevier Science, 2013-01)
The objectives of this study were to (a) analyze the distribution pattern of diatom assemblages in freshwater systems from central-western Argentina, (b) investigate the key climatic and limnological factors affecting the ...
Diatoms Assemblages in Quaternary Palaeoenvironmental of the South Coast of Buenos Aires Province, ArgentineAsociaciones de Diatomeas en Paleoambientes Cuaternarios de la Costa Sur de la Provincia de Buenos Aires, Argentina
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2002)
Effects of nutrient enrichment on epipelic diatom assemblages in a nutrient-rich lowland stream, Pampa Region, Argentina
(Springer, 2015-09-03)
We analyzed the diatom assemblages inhabiting the epipelic biofilm of a Pampean stream, characterized by their high basal nutrient levels, when exposed to a continuous surplus of inorganic nutrients. An in situ experience ...
Within versus between-lake variability of sedimentary diatoms: the role of sampling effort in capturing assemblage composition in environmentally heterogeneous shallow lakes
(Springer, 2018-12)
The effect ofwithin-lake diatom assemblages variability on sample representativity and itssubsequent impact on between-lake comparisons were addressed in threeenvironmentally heterogeneous shallow lakes from the Argentinean ...
Environmental and spatial drivers of diatom assemblages in the water column and surface sediment of tropical reservoirs
(Springer, 2019-10-01)
The relative contribution of environmental and spatial drivers of community structure has been the focus of many ecological studies. In the context of metacommunity theory, diatoms have been associated mainly with local ...
Late Pleistocene Diatoms of the lower Basin from the Quequén Salado River, Argentina
(Springer International Publishing, 2019-01)
Diatom assemblages from a site called Cueva del Tigre were studied. It is located in the lower basin of the Quequén Salado River, Buenos Aires province (38° 50´2.2"S - 60°32´7.1" W). The results are part of a project that ...
Distribution of epiphytic diatoms on five macrophytes from a Pampean shallow lake: host-specificity and implications for paleoenvironmental reconstructions
(Biopress Limited, 2017-07)
Epiphytic diatoms are an important component of death and fossil assemblages in macrophyte-dominated shallow lakes. In the Argentinean Pampas, the lack of studies on the composition, diversity and distribution of epiphytic ...
