New records of benthic diatoms from natural grazing surfaces of abalone (Haliotis spp.) in the Baja California Peninsula
(Oceánides, 2001)
The paper provides 39 new records of benthic diatoms for Isla Magdalena and 23 for the Baja California Peninsula. Specimens we recollected on rocky substrates from an abalone fishing site in April 1999 and 2000. Epilithic ...
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 ...
Epiphytic diatoms associated with red mangrove (Rhizophora mangle) prop roots in Bahía Magdalena, Baja California Sur, Mexico
(Universidad de Costa Rica, 2006)
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 ...
Nonselective diatom grazing by juveniles of red abalone (Haliotis rufesces Swainson, 1822) under experimental culture conditions
(Journal of Shellfish Research, 2010)
In abalone farms and laboratories of the Baja California peninsula in Mexico, young and postlarval abalone feed on benthic diatoms that grow on the artificial surfaces of the culture tanks, or on epiphytic diatoms growing ...
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 ...
