Camp (eds.), Gulf of Mexico–Origins, Waters, and Biota. Biodiversity. Texas A&M University Press, College Station, Texas. •7 Dinoflagellates (Dinoflagellata) of the Gulf of Mexico Karen A. Steidinger, Maria A. Faust, and David U. Hernández-Becerril In 1954, H. W. Graham stated, “Despite the importance of these organisms, the Gulf of Mexico is almost a terra incognita in respect to our knowledge of the dinoflagellate plankton.” In the same article, he gave a historic presentation on what dinoflagellate studies had been conducted, basic ecological considerations, and mentioned some common and oceanic species. It wasn’t until 1972 that a checklist of dinoflagellates (406 taxa) of the Gulf of Mexico was published by Steidinger, who used literature published up to 1971 as well as her own observations. The reference list in that paper contained many of the earlier works. Although records were scattered, and were principally in response to harmful algal blooms caused by dinoflagellates, there were studies that increased the number of taxa from less than 100 to 400 (Balech 1967a, b, c, Steidinger, Davis, and Williams 1967). Since 1967, the dinoflagellate taxa list has increased to 644 (this contribution and references herein; taxon summary). Dinoflagellate studies were most extensive in continental shelf waters, particularly off Mexico and Florida. The Gulf of Mexico is a tropical / warm temperate body of water that covers more than 8 degrees of latitude and has a corresponding biological diversity that is reflected in its dinoflagellate assemblages. There are several comprehensive works listing dinoflagellates within regions of the Gulf; all were consulted to compose the current checklist. These major contributions start with Balech (1967b). The 30 most common taxa of Balech (1967b) were Ceratium furca, C. massilense, C. trichoceros, C. fusus, Diplopelta asymmetrica, Dinoflagellata. After Lauterborn 1895. Dinopysis caudata, Ceratium tripos, Goniodoma polyedricum, Protoperidinium brochii, Ceratocorys horrida, Blepharocysta splendor-maris, Ceratium teres, Gonyaulax polygramma, Pyrophacus horologium, Ceratium extensum, Ceratium macroceros var. galicum, Protoperidinium conicum, P. depressum, Pyrocystis pseudonoctiluca, Podolampas palmipes, Ceratium contortum, Protoperidinium divergens, Ceratium trichoceros var. contrarium (= C. con131 132 ~ Dinoflagellates (Dinoflagellata) Dinoflagellata. After Schütt 1896. trarium), Ornithocercus magnificus, Ceratium hexacanthum, Amphisolenia bidentata, Protoperidinium crassipes, Podolampas palmipes, Ceratium contortum var. karstenii (= C. karstenii), and C. carriense. Only two of these species are toxic—Protoperidinium crassipes and Dinophysis caudata. Ceratium, Dinophysis, and Protoperidinium contain the most armored species among the dinoflagellate genera and therefore their representation would be expected to be high in any study. The reason armored species are represented more than unarmored dinoflagellates is because most of studies recording dinoflagellates from Gulf of Mexico and contiguous waters relied on preserved samples and light microscopy for detection of specimens. Unarmored species can round out when fixed and preserved, and although cells may be recognizable as unarmored, species determination may not be possible. One notable exception was the Hourglass Cruise phytoplankton study that used live material (Steidinger and Williams 1970) and was conducted on the West Florida Shelf over a 28-month period out to 170.5 km from shore. Six stations were occupied monthly. The majority of species were photosynthetic, armored, neritic and oceanic, and present throughout the year. A total of 232 taxa were identified. A more recent study (Licea et al. 2004) listed 252 dinoflagellate taxa from the southern Gulf of Mexico off Mexico. Again in this list, Ceratium, Dinophysis, and Protoperidinium had the highest number of taxa. The most common taxa (by number of sites at which found), in descending order, were: Ceratium furca var. eugrammum, C. fusus var. fusus, C. fusus var. seta, C. trichoceros, C. teres, C. breve var. breve, C. macroceros var. macroceros, C. massiliense, C. pentagonum var. pentagonum, Protoperidinium divergens, Podolampas palmipes, Ceratium tripos var. tripos, Dinophysis caudata var. caudata, Ornithocercus magnificus, Prorocentrum compressum, P. gracile, Ceratium furca var. furca, C. contortum var. contortum, C. horridum var. horridum, Prorocentrum micans, Ceratium kofoidii, Ceratocorys horrida, Pyrophacus steinii, Gonyaulax polygramma, Ceratium extensum, Gyrodinium fusiforme, Oxytoxum gracile, Protoperidinium mediterraneum, Amphisolenia bidentata, and Protoperidinium grande. This study, as well as most other studies of planktonic dinoflagellates, does include some benthic species that have become tychoplanktonic (Steidinger 1983). Of the 30 common taxa, Dinophysis caudata is known to produce toxins. As in many other studies on dinoflagellate diversity, this one relied on preserved specimens (Lugol’s solution) because of the length of the cruises. Lugol’s solution is a good fixative and specimens can be destained to observe finer structures. We have found that unacidified Lugol’s solution preserves refrigerated phytoplankton samples successfully for several years for dinoflagellates. If not refrigerated, samples will deteriorate. Samples fixed in 2% buffered gluteraldehyde and refrigerated provide well-preserved specimens for light microscopy and scanning electron microscopy. The current checklist has resulted from expanded studies as well as new technologies and methods. For example, scanning electron microscopic techniques, particularly in processing, have allowed identification of Steidinger, Faust, and Hernández-Becerril ~ 133 very small armored and unarmored species (Steidinger et al. 1996, 2001) as have molecular probes (Scholin et al. 2003), while new benthic dinoflagellates are being discovered and described (see Faust 1990, 1993, 1999, Faust and Gulledge 2002). Most described dinoflagellates are greater than 20 µm; however, with advanced techniques previously undescribed species or undifferentiated species are receiving attention within Pfiesteria, Symbiodinium, Heterocapsa, and Scrippsiella complexes (Taylor 1990). Karenia brevis, a dominant toxic species in the Gulf, is widely distributed and can reach concentrations of 108 cells L–1, but it is not the only Karenia present. Based on morphology and genetics, Daugbjerg et al. (2000) created the new genus Karenia, separating it from Gymnodinium and Gyrodinium based on, among other attributes, the apical groove. Now, K. brevis, K. mikimotoi, K. selliformis, K. longicanalis, K. papilionacea, and another, undescribed, species have been recorded from Gulf waters. The new species in some areas had previously been recorded as K. brevis and in one instance as the “butterfly type” (e.g., Steidinger, Davis, and Williams 1966). Advances in science typically advance species and distribution lists by providing new tools or new insights. Interestingly enough, the most widely distributed phytoplankter in the Gulf of Mexico is Trichodesmium erythraeum, a cyanobacterium (Ivanov 1966) that has been associated with large areas of sea surface discoloration. The seasonal occurrence of this species, as well as other factors, has led to hypotheses and studies on its role in supporting Karenia blooms through releasing organic nutrients (Walsh and Steidinger 2001, Mulholland et al. 2004). Species diversity for phytoplankton in temperate and tropical waters is typically greatest in open offshore waters and least in inshore coastal waters, yet cell abundance and standing stock is highest inshore (Saunders and Glenn 1969, Steidinger and Williams 1970, El-Sayed et al. 1972). Graham (1954, 223) has speculated that “the dinoflagellate fauna of the open Gulf is very likely quite similar to that of the Caribbean and the tropical Atlantic.” Balech’s (1967a, b, c) Caribbean and Gulf of Mexico data has supported this relationship. Halim (1967) has reported on more than 100 dinoflagellate taxa found off eastern Venezuela and the southeast Caribbean Sea, most of which are also reported for the Gulf of Mexico. Licea et al. (2004) came to the same conclusion—that is, dinoflagellate assemblages are very similar and are related to hydrographic regimes in the Caribbean Sea and the Gulf of Mexico being physically connected. This is certainly true for the open-water oceanic realms and even shelf waters. Estuaries can have different assemblages depending on their latitude, nutrient inputs, salinity, resident populations, and intruders. As with other studies, Licea et al. (2004) has found that dinoflagellates can dominate during summer months when environmental conditions are favorable. The circulation in the Gulf of Mexico is dominated by major currents, eddies, geostrophic flow, and winds. At the entrance to the Gulf across from the Yucatán Peninsula is Cuba. The Caribbean Current comes up the Caribbean Sea southwest of Jamaica and enters the Gulf through the Yucatán Channel. It then becomes the Loop Current, which is the major current in the eastern Gulf. The Loop Current produces eddies that propagate to the western Gulf. The Loop Current, the Florida Current (in the Florida Straits), and the Gulf Stream are all part of the Gulf Stream System. At the land-sea border, there are 33 major rivers and 207 estuaries, which represent contiguous waters of the Gulf; one of the largest inputs is the drainage basin of the Mississippi River (see Kumpf, Steidinger, and Sherman 1999). For a discussion on phytoplankton and upwelling, downwelling, and productivity, see Okolodkov (2003). Contiguous to the Gulf of Mexico are many bays, lagoons, and intracoastal waterways. The estuaries of the Gulf are often shallow embayments with different flushing times. For example, Tampa Bay averages 3.3 m deep and water has a residency time of more than 5 months. Because of high retention, dinoflagellate blooms (populations above background levels) can develop in these restricted-flow water bodies, and an embayment can have several blooms co-occurring within the system at the same time (Steidinger and Gardiner 1982). Some estuarine and neritic dinoflagellates produce benthic cysts that are functional in establishing water column populations. Both armored and unarmored species are capable of producing cysts (estimates up to 10%) but few life cycles have been documented (Garcés et al. 2002). Many of the benthic cysts are the result of a sexual cycle that produces zygotic benthic stages capable of short or long dormancies. Other species either have known benthic cysts (as deduced from encysting cysts and producing the motile, identifiable biflagellate stage) or are suspected of producing benthic stages. Bloom species can occur in the same small portion of a bay or coastal area year after year or periodically, and these species are suspected of having benthic stages. The distribution of planktonic dinoflagellates can be oceanic, neritic, estuarine, or in cases of overlap, oceanic / neritic or neritic / estuarine. Some species can be 134 ~ Dinoflagellates (Dinoflagellata) accidental invaders when the waters of the Loop Current and its eddies, or even the Mississippi River plume, entrain and transport oceanic or neritic species into the estuaries. Another example of this intruder condition is when west coast Florida bays have high salinities after droughts and K. brevis is able to penetrate the outer and even inner bays or harbors (Steidinger and Gardiner 1982). If the species is transported in a water mass that maintains its integrity (not mixed), it can survive. Methods and techniques for processing and analyzing water and sediment samples and for dinoflagellates are outlined in several books, for example, Sournia (1978) and Hallegraeff, Anderson, and Cembella (2003). Armored dinoflagellates are typically more tolerant of fixation and preservation than unarmored forms because of their thecal structure of polysaccharide plates within vesicles. Armored species also do well with further preparation such as staining and scanning electron microscopy. Unarmored dinoflagellates are more fragile and can become distorted with fixation, losing some external morphological characters necessary for identification. Advanced fixation schedules—for example, those in Truby (1997)—can overcome some of these difficulties, but such techniques are not practical for everyday light microscopy and quantification of abundance. Sampling protocol and methods influence results, and results should be interpreted accordingly. For rare species, presence and abundance may be functions of sample and aliquot size. If one cell of Protoperidinium crassipes was found in one liter of filtered seawater, the abundance would be 1 cell liter–1, but if one cell was found in a one milliliter aliquot from a one liter sample, the abundance would be 1000 cells liter–1. Plankton tow samples often find the rare species that water trap sampling would not, all because of sample size, but to quantify tow samples, the volume of water that flowed into the net must be known (see Sournia 1978 and Steidinger and Gardiner 1982 for discussions of sampling and analytical biases). Dinoflagellate systematics is advancing rapidly because of new technology. Classical taxonomists have a role in this advancement because they help define and frame the morphological unit and work with geneticists (Goulet and Coffroth 2004) to analyze species, genera, families, and their relatedness (Grzebyk, Sako, and Berland 1998). The agreement between the two fields in many species distinctions has been interesting and encouraging (Taylor 1999, 2004). It is this continual collaboration, using cultures and field specimens, that will help assess dinoflagellate variation within populations and species. In looking at past species lists and the most common dinoflagellates of those lists, some points need to be made about creating a compendium of species as a checklist. In the Balech (1967b), Steidinger and Williams (1970), and Licea et al. (2004) lists, the authors did the original analyses. In Steidinger (1972) and this checklist, the listing of species relies on the taxonomic expertise of others whose works contributed to the list, and therefore the specific reference is referred to in the table. Because of synonymies created over time, this checklist uses the most recently accepted synonym. The most common dinoflagellate species synonymies are listed in Steidinger and Tangen (1997) and Gomez (2004). Abbreviations The classification scheme used in this checklist is from Fensome et al. (1993). The columns of the list are coded by: una = unarmored; arm = armored; pho = photosynthetic with chloroplasts; het = heterotrophic without chloroplasts; plk = planktonic; ben = benthic; tox = toxin producing; bor = boreal; tem = temperate; trp = tropical; fre = freshwater; est = estuarine; ner = neritic; oce = oceanic; cep = coastal surface and epipelagic; csp = cosmopolitan; sym = symbiotic; and mix = mixotrophic. Temperate can be warm or cold temperate; tropical can include subtropical. Mixotrophic in this list refers to species that have chloroplasts but can feed on prey. Other definitions for mixotrophic infer chloroplasts and the uptake and utilization of organics. Mixotrophic species often have food vacuoles with chloroplasts inside. The last column, References and Endnotes, contains numbers that represent references for that specific taxon in the Gulf of Mexico or some other documentation. The more references cited, presumably the more reliable the occurrence. The acronym FWRI in the endnotes refers to the Florida Fish and Wildlife Research Institute, St. Petersburg, Florida.
