Diatom-based reconstruction of Holocene hydrological changes along the Colorado River floodplain (northern Patagonia, Argentina)
(Springer, 2018-05-10)
Diatom assemblages recovered from a Colorado River delta core in northern Patagonia, Argentina were analyzed in order to assess past environmental conditions. A total of 35 samples were selected from a 172-cm core extracted ...
Diatom-based inference model for conductivity reconstructions in dryland river systems from north Patagonia, Argentina
(Birkhauser Verlag Ag, 2021-07-21)
Dryland river systems support a diverse aquatic biota in semi-arid and arid landscapes, but they are increasingly vulnerable to natural and human impacts. This study provides the first modern diatom training set (n = 38) ...
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 ...
Changes in the epipelic diatom assemblage in nutrient rich streams due to the variations of simultaneous stressors
(Elsevier Gmbh, 2015-03-03)
Benthic diatoms are often used for assessing environmental conditions, such as water quality and habitat conditions in stream and river systems. Although laboratory experiments have shown that each diatom species have ...
Cyclostephanos salsae and Placoneis patagonica, two new diatoms (Bacillariophyta) from Laguna Cháltel in southern Patagonia, Argentina
(Gebruder Borntraeger, 2018-01)
Two new diatom species, Cyclostephanos salsae and Placoneis patagonica found in plankton, superfi cial sediments and quaternary lacustrine sediment samples from Laguna Cháltel, Southern Argentina, are described. The detailed ...
Stability of diatom composition in a variable lake environment: Lake Chascomús, Argentina
(Springer Tokyo, 2002-08)
Water and surficial sediment samples of Lake Chascomús and its tributaries were analyzed in order to relate changes in diatom community structure to chemical variables. Over the course of 13 months of sampling, the lake ...
Latitudinal diversity patterns of diatoms in the Southwestern Atlantic and Antarctic waters
(Oxford University Press, 2015-06)
Latitudinal changes in the species richness of planktonic diatoms in Southwestern Atlantic and Antarctic waters (29-76 S) were analyzed from local to regional scale in three spring and one summer seasons. A total of 220 ...
Assessing the influence of saline and alkaline environments in the preservation of pampean diatoms: an experimental approachEvaluación de la influencia de los ambientes salinos y alcalinos en la preservación de las diatomeas pampeanas: Un enfoque experimental
(Asociación Paleontológica Argentina, 2019-09)
Diatom dissolution is controlled by environmental conditions prevailing during fossilization. In Pampean shallow lakes, diatom dissolution showed important correlations with gradients of salinity, pH, carbonate, and ...
Modern diatom assemblages in surface sediments from meso-macrotidal estuaries of Patagonia, Argentina
(PanamJAS, 2015-04)
The composition and distribution of diatom assemblages from surface sediments in the littoral zone of meso and macrotidal estuaries from Patagonia (Argentina) were studied with the aim to recover modern data on diatom ...
Modern diatoms from a temperate river in South America: the Colorado River (North Patagonia, Argentina)
(Biopress Limited, 2017-04)
Diatom assemblage composition and distribution from surface sediment samples of the Colorado River, Patagonia were analysed in relation to environmental variables using multivariate techniques. The aim of this study was ...
