A new Late Triassic age for the Puesto Viejo Group (San Rafael depocenter, Argentina): SHRIMP U–Pb zircon dating and biostratigraphic correlations across southern Gondwana
Abstract The Puesto Viejo Group crops out in the San Rafael Block, southwest Mendoza, at approximately 35° S and 68°20′ W. It consists of the basal mainly grayish Quebrada de los Fosiles Formation
First record of Ostreopsis cfr. ovata on macroalgae in the Northern Adriatic Sea.
Ostreopsis ovata is an epiphytic potentially toxic dinoflagellate. It has a world-wide distribution, normally associated with other epiphytic or benthic dinoflagellates. In tropical seas O. ovata is
Plankton community structure and dynamics versus physical structure from Terra Nova Bay to Ross Ice Shelf (Antarctica)
Abstract During the austral summer 1997/1998, an oceanographic cruise was carried out on a large-scale grid in the Ross Sea. In this contribution, we focused our attention on the coastal area from
Microzooplankton biomass distribution in Terra Nova Bay, Ross Sea (Antarctica)
L'objet de cette etude est la distribution spatiale et verticale de l'abondance et de la biomasse du microzooplancton echantillonne pendant la premiere expedition antarctique italienne (1987/1988) a
Analyses of the Relationship Between Mucous Aggregates and Phytoplankton Communities in the Gulf of Trieste (Northern Adriatic Sea) by Multivariate Techniques
. Multivariate techniques (cluster analysis and Principal Component Analysis) applied on phytoplankton data collected in June, July, August, and September 1990, 1991, 1992, and 1993 in the Gulf of
Mucous aggregates under natural and laboratory conditions: a review
The genus Nitzschia was essential for the formation of mucous filaments, under the conditions of light and temperature applied during the experiments, and there was a transition from species belonging to centric diatoms toward pennate diatom.
Particulate matter and plankton dynamics in the Ross Sea Polynya of Terra Nova Bay during the Austral Summer 1997/98
Abstract The structure and variability of the plankton community and the distribution and composition of suspended particulate matter, were investigated in the polynya of Terra Nova Bay (western Ross
Microzooplankton biomass distribution in Terra Nova Bay
The spatial and vertical distribution of microzooplankton 20–200 million-mm abundance and biomass of the upper layers 0–100 m, collected during the first oceanographic Italian expedition in Antarctica 1987, is described.
Comparative Growth of Three Strains of Ostreopsis ovata at Different Light Intensities with Focus on Inter-Specific Allelopathic Interactions
A weak allelopathic effect on the growth of the three microalgae with an inhibition on thegrowth of C. monotis and P. minimum is revealed.
Delayed luminescence of Prorocentrum minimum under controlled conditions
DL intensity was best correlated with carbon content irrespective of strain and is proposed as an estimate of biomass and for differentiating between lag and exponential phases of growth.
