ALEXANDRIUM TAMUTUM SP. NOV. (DINOPHYCEAE): A NEW NONTOXIC SPECIES IN THE GENUS ALEXANDRIUM 1 (2004, background): “It is interesting to note that another strain of A. minutum (AL1 T), isolated from the Gulf of Trieste and included in the present LSU phylogeny, was not found to produce PSP toxins (Tillmann and John 2002).”
Control of the harmful alga Cochlodinium polykrikoides by the naked ciliate Strombidinopsis jeokjo in mesocosm enclosures (2008, background): “In particular, phototrophic dinoflagellates are important red tide organisms in marine ecosystems due to their adverse impacts on other organisms (e.g., Tillmann and John, 2002).”
The globally distributed genus Alexandrium: multifaceted roles in marine ecosystems and impacts on human health (2012, background): “typically results in immobilization of target cells followed by their lysis or cyst formation (Tillmann and John, 2002; Fistarol et al., 2004).”
On the allelochemical potency of the marine dinoflagellate Alexandrium ostenfeldii against heterotrophic and autotrophic protists (2007, methodology): “…effects upon other microalgae (Blanco and Campos, 1988; Arzul et al., 1999; Fistarol et al., 2004b) and towards heterotrophic protists (Hansen, 1989; Hansen et al., 1992; Matsuoka et al., 2000; Tillmann and John, 2002; Fistarol et al., 2004b) is rather widely expressed within the genus Alexandrium.”
Allelopathic effects of Cochlodinium polykrikoides isolates and blooms from the estuaries of Long Island, New York, on co-occurring phytoplankton. (2010, background): “The allelopathic effects of HABs are often caused by extracellular chemical agents that are different from the chemicals responsible for poisoning humans via shellfish (Tillmann & John 2002, Legrand et al. 2003, Granéli & Hansen 2006, Prince et al. 2008, Tillmann et al. 2008b).”
Interactions between Planktonic Microalgae and Protozoan Grazers1 (2004, background): “However, results presented by Tillmann and John (2002) clearly showed that lytic toxins of Alexandrium spp., being distinct from PSP, are extracellular, making it unlikely that cell lysis of P. kofoidii was causatively linked to ingestion.”
Allelopathy in Alexandrium spp.: effect on a natural plankton community and on algal monocultures (2004, background): “Also, Tillmann & John (2002) tested whether the allelopathic effect of different strains of Alexandrium on heterotrophic dinoflagellates could have been caused by the bacteria present in the cultures.”
Harmful algal blooms of allelopathic microalgal species: The role of eutrophication (2008, background): “Various workers (Pratt, 1966; Keating, 1977; Sharp et al., 1979; Tillmann and John, 2002) have reported the presence of toxic metabolites or allelochemicals in culture filtrates from various algae.”
Factors Influencing Allelopathy and Toxicity in Prymnesium parvum 1 (2010, background): “…parvum, such as Alexandrium spp., Chrysochromulina polylepis, Cylindrospermopsis raciborskii, variation in strains from those producing no toxins to extremely high cellular toxin levels have been found (Arzul et al., 1999; Tillmann and John, 2002; Fistarol et al., 2004a,b; Figueredo et al., 2007).”
A comparative study on recurrent blooms of Alexandrium minutum in two Mediterranean coastal areas. (2005, background): “, 2003), or competition and allelopathy (Cannon, 1996; Arzul et al., 1999; Tillmann and John, 2002; Fistarol et al., 2004).”
Kill and eat your predator: a winning strategy of the planktonic flagellate Prymnesium parvum (2003, methodology): “Immobilisation was estimated by counting the number of moving O. marina cells using a slightly modified droplet live-counting procedure as described by Tillmann & John (2002).”
Allelopathic effects of Alexandrium tamarense on other algae: evidence from mixed growth experiments. (2009, background): “The potential relief of A. tamarense from competition for nutrients etc., together with the benefit of reducing grazing loss by protistan grazers (Hansen 1989, Tillmann & John 2002, Fistarol et al. 2004b), is likely to be important for A. tamarense bloom development.”
