A large-scale stream benthic diatom database
(Springer, 2005-11)
A relational database linking benthic diatom records, taxonomic nomenclature including synonyms, and corresponding environmental data has been built in MS Access. It allowed flexible and long-term use of a relatively ...
Substrate-dependent differences between the structures of epiphytic and epilithic diatom assemblages off the southwestern coast of the Gulf of California
(Botanica Marina, 2012)
To test the postulate that diatom assemblage structures differ between those growing on macroalgae and those on rocks used as substratum by macroalgae, we analyzed 29 samples of macroalgae and 15 of rocky substrata from ...
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 ...
Gas-floating aggregates of Antarctic benthic diatoms
(Matters Select, 2017-12)
We report the formation of gas-vesicle stalked aggregates formed by a mucoid-sediment layer colonized by pennate diatoms and occasional centric diatoms. The most frequently occurring diatoms within this layer belonged to ...
Benthic diatoms and some environmental conditions in three lowland streams
(EDP Sciences, 2002-12)
This article reports on the ecological preferences of benthic diatoms in relation to pH, conductivity and organic pollution-eutrophication and their tolerance spectrums. Three Pampean streams subjected to different human ...
Marine diatoms from Buenos Aires coastal waters (Argentina): II. Thalassionemataceae and Rhaphoneidaceae
(Sociedad de Biología de Chile, 2007)
Marine diatoms from Buenos Aires coastal waters (Argentina). V. Species of the genus Chaetoceros
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2008)
Effects of dredging on benthic diatom assemblages in a lowland stream
(Elsevier, 2009-12)
The objective of this study was to assess the effects of dredging on the structure and composition of diatom assemblages from a lowland stream and to investigate whether the response of diatom assemblages to the dredging ...
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 ...
