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 ...
Paleoecological Significance of Diatoms in Argentinean Estuaries: What Do They Tell Us About the Environment?
(Nova Science Publishers, 2010)
Estuaries are productive ecosystems of high ecological value. They are important habitats for various species and those of highest value are protected by national and international conventions. This book highlights possible ...
