(2015) revealed within the Pyrodinium clade, both Indo-Pacific and Atlantic-Caribbean ribotypes, suggesting that P. bahamense is a species complex. The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. compressum in field samples is difficult because the bloom does not discolor the water and the species occur in low cell densities. doi: 10.1111/j.1440-183.2004.00364.x, Limoges, A., Kielt, J.-F., Radi, T., Ruíz-Fernandez, A.

R., Asanuma, I., Turk, D., et al. However, it is highly probable that its distribution is as broad as that of vegetative cells, considering that P. bahamense cysts have been found in the central Gulf of California (Martínez-Hernández and Hernández-Campos, 1991), and in Baja California northern limit (Peña-Manjarrez et al., 2001, 2005) (Figure 1A).

Pyrodinium bahamense has caused more human illnesses and fatalities than any other PST producing dinoflagellate in Mexico (Table 1). This gulf has an average and a maximum water depth of ∼250 m and ∼1,000 m, respectively (Vásquez-Bedoya et al., 2008). However, a similar co-occurrence between P. bahamense and Pseudo-nitzschia species has also been reported in the Indian River Lagoon, Florida (Phlips et al., 2004). A. Benítez, and G. Gold-Bouchot (Mérida: UAC), 117–132. This prevents, in the short term, the establishment of management plans to minimize HABs impacts as well as the advance of the understanding and prediction of them.

Concerning ambient variables, the record of in situ hydrological variables such as temperature and salinity are the most common, while nutrients rarely are considered. Inst. Research on P. bahamense cysts is mainly developed with palynological procedures (de Vernal et al., 2010). Cortés-Altamirano, R., Muñoz-Cabrera, L., and Sotomayor-Navarro, O.

Until now short-term studies have been undertaken, and there is no permanent scientific monitoring. In contrast, in the southern Gulf of California, moderate (63–151 × 103 cells L-1), and short-term blooms are influenced by a short summer rainy season (August–September), relatively high seawater temperature (25–32°C), typical salinity (31–36 ups), intense sunlight, and relatively high concentrations of ammonium (0.37–33.04 μM) and phosphates (0.68–2.87 μM); the last one, in turn, depending on rainfall and runoff and seems stronger on the eastern side of the gulf (Morquecho et al., 2012).

(2015); Maciel-Baltazar (2015); Poot-Delgado (2016); Campos-Campos et al. The dinoflagellate producing the light show, Pyrodinium bahamense, happens to be one that At that time, it was believed that the species had a distribution restricted to the Bahamas; however, at present, the vegetative stage (Figures 1B,C) is distributed in almost all coastal margin of Gulf of Mexico, Caribbean Sea, Gulf of California, and Mexican Pacific (Figure 1A). Ser. (E) Empty cyst showing chorate processes. (2013). Sterols, which are membrane‐reinforcing lipids in eukaryotes, display a great diversity of structures in dinoflagellates, with some serving as chemotaxonomic markers. It is worth noting that although Mertens et al. Monitoring for food safety on the coasts of Mexico, with particular emphasis on aquaculture areas or the exploitation of marine products, requires essential adjustments to validate and strengthen the management and decision-making database. The identification of species is carried out by different techniques such as light and scanning electron microscopy, which allows the morphological and theca arrangement observations.

However, the information that we currently have on blooms dynamics, and toxicological and autecological characteristics of harmful species inhabiting Mexico and Latin America is insufficient.

But in 2003, this unique habitat was adversely impacted by the local practice of swimming in the area. Pyrodinium bahamense has particular importance since it has caused a significant impact on human health, mainly in southern Mexican Pacific. The entity most affected was Oaxaca, followed by Guerrero and Chiapas (COFEPRIS, 2018). Nac. 69, 285–317. Satellite ocean-color observations of the tropical Pacific Ocean.

The thecate Pyrodinium bahamense is a very important member of paralytic shellfish toxin (PST)-producing marine dinoflagellates especially in tropical waters. 6, ed. However, comparative research is needed on both coasts of Mexico to define precisely the hydrologic and climatic variables that are triggering P. bahamense blooms. 52, 419–428. Oceanogr. Ecol. J.

Esc. *Correspondence: Lourdes Morquecho, lamorquecho@cibnor.mx, Front. Sci. This species have caused more human illnesses and fatalities than any other PST producing dinoflagellates. This distribution is likely attributed to the scarcity of the vegetative stage along the Gulf of California, whereas its presence in the phosphorite, could indicate the influence of slightly hypersaline and tropical warmer water masses. looms of P. bahamense can occasionally lead to fish kills by depleting the water of dissolved oxygen. Pyrodinium bahamense, is one of the most critical harmful algal bloom (HABs) organisms in South Asian coastal waters (Mertens et al., 2015). (2012). An.

For example, the dinoflagellate may develop persistent moderate and massive toxic blooms in Guerrero, Oaxaca, and Chiapas coastal margin (Figure 1), which is characterized by a large-scale hydrological and atmospheric influence (Table 1); while in the southern Gulf of California, moderate blooms are restricted to coastal lagoons inhabited by mangroves, and develop only during the summer and the short-term rainy period.
