Three types of feeding mechanisms are known in dinoflagellates: pallium feeding, tube and direct engulfment. Pallium has only been described for heterotrophic thecate species ( Protoperidinium, Diplopsalis group). Tube is commonly found among both naked mixotrophic dinoflagellates (e.g. Amphidinium, Dinophysis, Gyrodinium, Peridiniopsis ). Direct engulfment mainly Gymnodinium, Noctiluca ): recently, however, some have shown to use this mechanism as well. Feeding behavior involves several...
The Symbiodiniaceae are a family of marine dinoflagellates known mostly for their endosymbiotic interactions with invertebrates and protists, but facultatively exclusively free-living life histories in this also evident. A recent systematic revision the replaced clade-based nomenclature seven divergent lineages "Symbiodinium" sensu lato one based on formally described genera. revised taxonomy was not extended to whole group because type species describe new genus each remaining clades...
The syndrome Amnesic Shellfish Poisoning (ASP) results from ingesting sea food contaminated by a neurotoxin, domoic acid. Diatoms of the genera Pseudo-nitzschia and Nitzschia are responsible for production this toxin. A total eleven species were identified during two plankton surveys at entrance in southern channels Ria de Aveiro, largest lagoon on west coast Portugal. During first survey, conducted February to October 2000, following identified: P. australis, cuspidata, delicatissima,...
proposed to reject the name Gonyaulax catenella Whedon & Kof., basionym of Alexandrium (Whedon Kof.) Balech in order permit usage more recent fundyense Balech.The proposal was based on Art.56.1 ICN (McNeill al. Regnum Veg.154.2012), which states that a would cause disadvantageous nomenclatural change may be for rejection.In our opinion authors do not provide necessary background this and misinterpret some data literature.In following we argue should rejected as its acceptance will serious...
Predictive models based on invertebrate assemblages are a powerful tool for assessing water quality. Yet, few attempts have been made to build predictive with diatoms although they widely used in freshwater assessment and among the mandatory biological monitoring elements indicated European Water Framework Directive. We built two central Portugal, one macroinvertebrates other diatoms, using data sampled simultaneously from 43 sites Spring of 2004 2005. Our objective was test performance...
From June 2004 to December 2007, samples were weekly collected at a fixed station located the mouth of Ria de Aveiro (West Iberian Margin). We examined seasonal and inter-annual fluctuations in composition community structure phytoplankton relation main environmental drivers assessed influence oceanographic regime, namely changes frequency intensity upwelling events, over dynamics assemblage. The consistently handled final subset 136 OTUs (taxa with relative abundance > 0.01%) was...
Amphidinium lacustre Stein, non sensu auctt. was identified by reference to original descriptions, which differ significantly from later interpretations. Mixed cultures containing A. , cryptomonads, Spermatozopsis exsultans Korshikov, and small chlorelloid cells were examined for feeding events. The dinoflagellate ingested the cytoplasm of leaving periplast, completely cells. A peduncle used in initial stages prey capture, although it not visible during food uptake. ultrastructure typical...
On the basis of morphological (light and electron microscopy) as well molecular data, we show that widely distributed freshwater dinoflagellate presently known Peridiniopsis berolinensis is a member family Pfiesteriaceae, an otherwise marine estuarine dinoflagellates. P. close relative species, which it resembles in morphology, mode swimming, food-uptake mechanism, partial LSU rRNA sequences.

:The fine structure of the freshwater Peridinium aciculiferum and closely related Baltic Sea species currently known as Scrippsiella hangoei were examined in serial sections. The name malmogiense is shown to be an earlier synonym restored species. Although both have been included genus Peridinium, their phylogenetic positions are within Thoracosphaeraceae, close specialized predators pfiesteriaceans photosynthetic Chimonodinium lomnickii. fine-structural features two proved very similar,...
Combining Mn and Sr co-doping β-TCP powder with sucrose addition in the setting liquid enhances injectability, mechanical biological performance of brushite-forming cements, renders them promising for minimally invasive surgery applications.
Peridiniopsis berolinensis (Lemmermann) Bourrelly (Peridiniales, Dinophyceae) is attracted to injured or dying protists (including other dinoflagellates and cells of its own kind) small metazoans. Punctured nematodes were used for experimental induction feeding. uses a filament establish connection with potential food items ingests their fluid contents through feeding tube protruded from the mid-ventral region cell.

The name Peridinium palatinum Lauterborn currently designates a freshwater peridinioid with 13 epithecal and six cingular plates, no apical pore complex. Freshwater dinoflagellate floras classify it in group together P. pseudolaeve M. Lefèvre.

ABSTRACT. Sphaerodinium cracoviense was collected near Cracow, Poland, and analysed by light microscopy, scanning electron serial‐section transmission microscopy. Thecae showed a peridinioid type of plate arrangement with unusual numbers in the anterior intercalary postcingular series: 4 6, respectively. The apical pore S. differed from typical seen many thecate forms included furrow knob‐like protuberances reminiscent area some woloszynskioids. flagellar apparatus three microtubular roots...
