“…CFP outbreaks outside of endemic areas have been attributed to consumption of imported toxic fish 6 and expanding biogeographical range of Gamberdiscus spp. and ciguatoxic fish 7,8 . CFP symptoms vary with the regional origin of the toxin 9 and occur within 0.5-12 h of toxic fish consumption 10 .…”

“…Recently, Gambierdiscus has been found on oil production platforms along the west Texas coast (Villareal et al, 2007) and off Cape Fear North Carolina (Litaker et al, 2009). Benthic dinoflagellates including Gambierdiscus in coral-reefs often are found on the surface of corals and macrophytes, and are food source of herbivore fishes.…”

“…Several studies have predicted that as global sea surface temperatures increase, Gambierdiscus will expand its geographic range, increasing the number of people at risk of ciguatera fish poisoning (Dickey & Plakas, 2010;P. A. Tester, Feldman, Nau, Kibler, & Wayne Litaker, 2010;Villareal et al, 2007). Gambierdiscus species have been shown to have different temperature ranges of growth as well as different ranges in toxicity Xu, Richlen, Liefer, Robertson, & Kulis, 2016).…”

A. Tester et al, 2010;Villareal et al, 2007). Since no method is currently available to rapidly and cheaply test fish for ciguatoxins, fishermen instead use known poisoning histories of localized fishing areas to determine the risk of their catch.…”

Phenotypic diversity within two toxic dinoflagellate genera: environmental and transcriptomic studies of species diversity in Alexandrium and Gambierdiscus

Dinoflagellates are a diverse group of single-celled eukaryotic phytoplankton that are important for their unique genetics and molecular biology, the multitude of ecological roles they play, and the ability of multiple species to produce toxins that affect human and ecosystems health. Two dinoflagellate genera, Alexandrium and Gambierdiscus each contain species that can cause human poisoning syndromes, although the methods of toxin transfer, accumulation, and exposure are very different. Gambierdiscus is a benthic organism that produces lipophilic ciguatoxins that can bioaccumulate in coral reef fish and cause ciguatera fish poisoning (CFP) in human consumers. Alexandrium is a planktonic species that produces saxitoxins that can directly accumulate in shellfish and cause paralytic shellfish poisoning (PSP) in humans. Both genera contain multiple species that vary dramatically in toxicity and physiology. Through transcriptomic analysis, this thesis describes the genetic diversity present across dinoflagellates that produce saxitoxin, elaborating on differences in their complement of genes within the saxitoxin biosynthesis pathway. This study demonstrated retention and expression of some of these saxitoxin genes by non-toxic species within Alexandrium, as well as in Gambierdiscus, which does not produce saxitoxins. Furthermore it confirmed the presence of certain transcripts only in toxin-producing species. This thesis then developed novel fluorescence in situ hybridization (FISH) probes that can be used to identify and enumerate six Gambierdiscus species, thereby enabling the community composition of Gambierdiscus to be examined in a quantifiable manner. The probes were tested in the laboratory on cultures, and then successfully applied to field samples from Florida Keys and Hawai'i. Gambierdiscus species are diverse in both their toxicity and optimal temperature ranges for growth. Analysis of Gambierdiscus community composition in an area of variable temperature allowed the characterization of species shifts that were driven both by a seasonal increase in mean seawater temperatures and spatial variability of temperature experienced between tidal pools. Overall this thesis advances the knowledge of dinoflagellate genetics and ecology, aids in the characterization of species harmful to public health, and provides tools and approaches to help monitor and manage harmful effects from these species, including some that are projected to increase with climate change.
