A cell cycle study was carried out over a 22 h period on 9 and 10 November to describe the physiological status and the short-term variability in cell toxin quota of D. acuta at the time of the annual maximum of lipophilic toxins in shellfish. At that time, the population of D. acuta showed an extremely low division rate (μ = 0.03 d–1), a high frequency of dead cells (up to 15%) and cells with starch granules (up to 93%), and no evidence of recent mixotrophic behaviour. Still, the cells, which did not perform vertical migration, aggregated around salinity-driven density discontinuities in the top 5 m and had a high cell toxin quota (deter- mined by liquid chromatography-mass spectrometry) for this species. A 3.5-fold difference was found between maximum (during the night) and minimum values of cell toxin quota. -

[email protected] Abstract Microbial interactions are crucial for Earth ecosystem function, yet our knowledge about them is limited and has so far mainly existed as scattered records. Here, we have surveyed the literature involving planktonic protist interactions and gathered the information in a manually curated Protist Interaction DAtabase (PIDA). In total, we have registered ~2,500 ecological interactions from ~500 publications, spanning the last 150 years. -

Dinoflagellate infections have been reported for different protistan and animal hosts. We report, for the first time, the association between a dinoflagellate parasite and a rotifer host, tentatively Synchaeta sp. (Rotifera), collected from the port of Valencia, NW Mediterranean Sea. The rotifer contained a sporangium with 100–200 thecate dinospores that develop synchronically through palintomic sporogenesis. This undescribed dinoflagellate forms a new and divergent fast-evolved lineage that branches amongthe dinokaryotic dinoflagellates. 1. Introduction form independent lineages with no evident relation to other dinoflagellates [12]. In this study, we describe a new lineage of The alveolates (or Alveolata) are a major lineage of protists an undescribed parasitic dinoflagellate that largely diverged divided into three main phyla: ciliates, apicomplexans, and from other known dinoflagellates. -

Although the number and layout of the thecal plates is highly conserved, the morphological diversity within the 22 group is outstandingly high for dinoflagellates. Previous hypotheses about character evolution 23 within dinophysoids based on comparative morphology alone are currently being evaluated by 24 molecular phylogenetic studies. Sinophysis is especially significant within the context of these 25 hypotheses because several features within this genus approximate the inferred ancestral states 26 for dinophysoids as a whole, such as a (benthic) sand-dwelling lifestyle, a relatively streamlined 27 theca and a heterotrophic mode of nutrition. We generated and analysed small subunit (SSU) 28 rDNA sequences for five different species of Sinophysis, including the type species (S. ebriola, 29 S. stenosoma, S. grandis, S. verruculosa and S. microcephala). We also generated SSU rDNA 30 sequences from the planktonic dinophysoid Oxyphysis (O. -

We observed similar pigment 15 composition, but quantitative differences, in four Dinophysis species (D. acuminata, D. acuta, D. 16 caudata and D. tripos), Mesodinium and Teleaulax. Dinophysis contained 59-221 fold higher chl a 17 per cell than T. amphioxeia (depending on the light conditions and species). To explain this result, 18 several reasons (e.g. more chloroplasts than previously appreciated and synthesis of new pigments) 19 were are suggested. 20 KEYWORDS: Dinophysis, Mesodinium, Teleaulax, pigments, HPLC. 21 22 INTRODUCTION 23 Photosynthetic Dinophysis species contain plastids of cryptophycean origin (Schnepf and 24 Elbrächter, 1999), but there continues a major controversy around their nature, whether there exist 25 are only kleptoplastids or any permanent ones (García-Cuetos et al., 2010; Park et al., 2010; Kim et 26 al., 2012a). -
Diarrhetic Shellfish Toxicity in Relation to the Abundance of Dinophysis Spp

In the German Bight (North Sea) around the island of Helgoland, 4 toxic Dinophysis species occur, of which 2 exhibited successive biomass maxima in summer 2000 (D. norvegica Claparède et Lachmann 1859 with cell concentrations of max. 400 cell l–1 and D. acumi- nata Claparède et Lachmann 1859 with max. cell concentrations of over 4000 cells l–1). In contrast to findings in other marine areas, toxicity of Mytilus edulis Linné 1758 could be clearly attributed to the observed increases in cell abundances of both species. In several Mytilus samples toxin concentra- tions (max. 460 ng diarrhetic shellfish poisoning [DSP] toxins g–1 hepatopancreas) were in a range which is considered dangerous for human consumption. While mussel toxicity coincided with concentration increases of both Dinophysis species, toxicity of the particulate substance in the water (max. 26 ng l–1) could be detected only during cell concentration maxima of D. -
