Réponses physiologiques et biochimiques à une limitation nutritive en phosphore ou en azote sur la réorientation métabolique des lipides polaires chez différentes espèces de microalgues marines
Provedor de dados: 5
Autores: Huang, Bing.
Betaine lipids (BL) are P-free polar lipids, conversely to phospholipids (PL). The metabolic reorientation induced by phosphorus (P) limitation in microalgae producing BL (Tisochrysis lutea and Diacronema lutheri, Haptophyta) or producing low levels of BL (Phaeodactylum tricornutum, Bacillariophyta) was compared to that induced by nitrogen (N) limitation. The carbon destiny and flow in different biosynthetic pathways were studied with a multidisciplinary approach. P or N limitation differently affected carbon metabolism according to microalgal species. P limitation highly decreased photosynthetic activity and respiration of P. tricornutum and T. lutea. Consequently, carbon accumulation was higher than under N limitation in these two species. Both...

The phytoplankton of Guanabara Bay, Brazil: I. historical account of its biodiversity
Provedor de dados: 49
Autores: Villac,Maria Célia; Tenenbaum,Denise Rivera.
This is a historical account of the biodiversity of phytoplankton in Guanabara Bay, Brazil. It is based on 57 publications that refer to sampling carried out between 1913 and 2004. The publications included are those with direct microscopic identification. Although 80% of the studies focus on ecological issues that tend to mention only the most abundant species, 24 publications provide comprehensive check-lists at the species level, especially of taxa &gt; 20 μm. The inventory of species includes, to date, 308 taxa among 199 diatoms, 90 dinoflagellates, 9 cyanobacteria, 5 euglenophyceans, 1 chlorophycean, 1 prasinophycean, 1 silicoflagellate, and 2 ebriids. The most conspicuous species were the dinoflagellate Scrippsiella trochoidea and diatoms from the...

The phytoplankton biodiversity of the coast of the state of São Paulo, Brazil
Provedor de dados: 49
Autores: Villac,Maria Célia; Cabral-Noronha,Valéria Aparecida de Paula; Pinto,Thatiana de Oliveira.
The objective of this study is to compile the inventory of nearly 100 years of research about the phytoplankton species cited for the coast of the state of São Paulo, Brazil. A state-of-the-art study on the local biodiversity has long been needed to provide a baseline for future comparisons. This type of data is scattered in old scientific journals and in the so-called "grey literature", and are in need of nomenclature updating. Twenty-six publications are considered. The earliest sampling record is from 1913 (?) and the most recent from 2002. This checklist compiled from the literature was complemented with primary data collected between August 2004 and July 2006, recent surveys of the surf-zone of 20 beaches located along the coast and of a mariculture...
