The red-crab bloom off the west coast of Baja California, Mexico
(Journal of Plankton Reseach, 1998)
Hydroacoustic data indicate that the benthic red crab Pleuroncodes planipes (Stimpson, 1860) rises from the bottom towards the surface at dusk from very compacted patches settled on the continental shelf. The behaviour is ...
Nitrogenous Nutrients Promote the Growth and Toxicity of Dinophysis acuminata during Estuarine Bloom Events
(Public Library of Science, 2015-04)
Diarrhetic Shellfish Poisoning (DSP) is a globally significant human health syndrome mostcommonly caused by dinoflagellates within the genus Dinophysis. While blooms of harmful algae have frequently been linked to excessive ...
Potentially toxic Pseudo-nitzschia species in plankton and fecal samples of Eubalaena australis from Península Valdés calving ground, Argentina
(Elsevier Science, 2015-10)
Península Valdés (PV) in Argentina is an important calving ground for the southern right whale Eubalaena australis. However, a high mortality of calves has been observed in the last years, which could be associated with ...
Environmental and biological factors controlling the spring phytoplankton bloom at the Patagonian shelf-break front - Degraded fucoxanthin pigments and the importance of microzooplankton grazing
(Pergamon-Elsevier Science Ltd, 2016-08)
The aim of this study was to investigate the biotic and abiotic factors controlling the spring phytoplankton blooms at the Patagonian shelf-break front (PSBF). Using a CHEMTAX analysis of HPLC pigment data and other methods, ...
Invasion of the dinoflagellate Ceratium furcoides (Levander) Langhans 1925 at tropical reservoir and its relation to environmental variablesInvasão do dinoflagelado Ceratium furcoides (Levander) Langhans 1925 em um reservatório tropical e sua relação com as variáveis ambientais
(Instituto Virtual da Biodiversidade | BIOTA - FAPESP, 2012)
Dinoflagellates of the genus Ceratium are chiefly marine but there are rare occurrences in freshwater. In this study we analyze the invasion and progressive establishment of Ceratium furcoides, an exotic species, in the ...
Influence of the winter phytoplankton bloom on the settled material in a temperate shallow estuary
(Polish Acad Sciences Inst Oceanology, 2015-01)
The development of the phytoplankton winter bloom and the accumulation of particulate suspended matter (PSM) inside sediment collectors were assessed in the inner zone of the Bahía Blanca Estuary. The phytoplankton bloom ...
Effect ofplankton-derivedorganic matter on themicrobial community of coastal marine sediments
(Amsterdam, 2014-08-17)
An experimental study was carried out to observe the microbial response to two different plankton-derived organic matter inputs in a coastal sedimentary community of Ubatuba, São Paulo, SE Brazil. The organic enrichment ...
Environmental patterns and biomass distribution of gelatinous macrozooplankton. Three study cases in the South-western Atlantic Ocean
(Instituto de Ciencias del Mar Barcelona, 2000-12)
Periodic swarms or blooms of gelatinous macrozooplankton have a negative effect on many human activitiessuch as tourism, fisheries, and industry, but for several reasons (sampling procedures, underestimation of their real ...
