The paleoecology of Late Cretaceous upwelling events from the upper Magdalena basin, Colombia
(SEPM-SOC SEDIMENTARY GEOLOGY, 2003-10-01)
Ten planktonic foraminiferal zones are identified and six stratigraphic sequences are interpreted in the Turonian-Maastrichtian interval of the Michu-1 well in the Upper Magdalena Basin. Anoxic bottom-water conditions ...
The emergence of Dinophysis acuminata blooms and DSP toxins in shellfish in New York waters
(Elsevier Science, 2013-03)
The dynamics of Dinophysis acuminata and its associated diarrhetic shellfish poisoning (DSP) toxins, okadaic acid (OA) and dinophysistoxin-1 (DTX1) as well as pectenotoxins (PTXs), were investigated within plankton and ...
Shionodiscus gaarderae sp. nov. (Thalassiosirales, Thalassiosiraceae), a bloom-producing diatom from the southwestern Atlantic Ocean, and emendation of Shionodiscus bioculatus var. bioculatus
(Biopress Limited, 2018-01)
The recently established diatom genus Shionodiscus is characterized as possessing a labiate process on the valve face and strutted processes with long internal and reduced, or no, external extensions. Many Thalassiosira ...
High abundance of Amphidomataceae (Dinophyceae) during the 2015 spring bloom of the Argentinean Shelf and a new, non-toxigenic ribotype of Azadinium spinosum
(Elsevier Science, 2019-04)
Azaspiracids (AZA) are the most recently discovered group of lipophilic marine biotoxins of microalgal origin, and associated with human incidents of shellfish poisoning. They are produced by a few species of Amphidomataceae, ...
Cytomorphometric characterization of a population of Ceratium hirundinella fa. austriacum (Dinophyta) during a bloom in a reservoir of the Province of Buenos Aires, Argentina
(Ingenta, 2007-12)
Ceratium hirundinella (O. F. Müller) Dujardin is a dinoflagellate frequently found in freshwater plankton in Argentina. It may form - together with cyanobacteria - massive blooms, particularly in autumn-winter. From 1997 ...
Biodiversity and distribution patterns of planktonic cnidarians in San Matı´as Gulf, Patagonia, Argentina
(Inter-Research, 2013-02)
The special location (40–42°S in the Southwestern Atlantic Ocean) and the hydrodynamic regime (limited water exchange with open ocean) in San Matı´as Gulf (Argentina) seem to produce a particular fauna of planktonic ...
Analysis of the hydrographic conditions and cyst beds in the San Jorge Gulf, Argentina, that favour dinoflagellate population development including toxigenic species and their toxins
(Elsevier Science, 2015-01)
The overlay of cooler nutrient enriched Beagle–Magellan water with warmer nutrient depleted shelf water and a strong stratification of the water column in the San Jorge Gulf region, Argentina, coincided with relatively ...
Biodiversity and distribution patterns of planktonic cnidarians in San Matías Gulf, Patagonia, Argentina
(Wiley, 2013-02)
The special location (40?42°S in the Southwestern Atlantic Ocean) and the hydrodynamic regime (limited water exchange with open ocean) in San Matías Gulf (Argentina) seem to produce a particular fauna of planktonic ...
Morphological and molecular studies of Sphaerospermopsis torques-reginae (Cyanobacteria, Nostocales) from South American water blooms
(INT PHYCOLOGICAL SOCLAWRENCE, 2012)
Sphaerospermopsis torques-reginae (Komarek) Werner, Laughinghouse IV, Fiore & Sant'Anna comb. nov. was originally described as Anabaena torques-reginae Komarek from planktonic populations of Cuban eutrophic environments, ...
