Journal ArticleDOI
Ocean warming since 1982 has expanded the niche of toxic algal blooms in the North Atlantic and North Pacific oceans.
Christopher J. Gobler,O. M. Doherty,Theresa K. Hattenrath-Lehmann,Andrew W. Griffith,Yoonja Kang,R. Wayne Litaker +5 more
TL;DR: High-resolution sea-surface temperature records and temperature-dependent growth rates of two algae that produce potent biotoxins are used and it is concluded that increasing ocean temperature is an important factor facilitating the intensification of these, and likely other, HABs and thus contributes to an expanding human health threat.
Journal ArticleDOI
Formal Revision of the Alexandrium tamarense Species Complex (Dinophyceae) Taxonomy: The Introduction of Five Species with Emphasis on Molecular-based (rDNA) Classification
Uwe John,R. Wayne Litaker,Marina Montresor,Shauna A. Murray,Michael L. Brosnahan,Donald M. Anderson +5 more
TL;DR: Data on morphology, ITS/5.8S genetic distances, ITS2 compensatory base changes, mating incompatibilities, toxicity, the sxtA toxin synthesis gene, and rDNA phylogenies were consistent with each group representing a distinct cryptic species.
Journal ArticleDOI
Global distribution of ciguatera causing dinoflagellates in the genus Gambierdiscus.
R. Wayne Litaker,Mark W. Vandersea,Maria A. Faust,Steven R. Kibler,Amy W. Nau,William C. Holland,Mireille Chinain,Michael J. Holmes,Patricia A. Tester +8 more
TL;DR: The observations suggest that CFP events are driven more by inherent differences in species toxicity than by environmental modulation, which may affect the development of an early warning system for CFP.
Journal ArticleDOI
Taxonomy of Gambierdiscus including four new species, Gambierdiscus caribaeus, Gambierdiscus carolinianus, Gambierdiscus carpenteri and Gambierdiscus ruetzleri (Gonyaulacales, Dinophyceae)
R. Wayne Litaker,Mark W. Vandersea,Maria A. Faust,Steven R. Kibler,Mireille Chinain,Michael J. Holmes,William C. Holland,Patricia A. Tester +7 more
TL;DR: The GTT-91 isolate has been well characterized genetically and the original SEM stub of this isolate archived at the Smithsonian Institution has been re-examined to provide a more detailed morphological analysis of the epitype.
Journal ArticleDOI
RECOGNIZING DINOFLAGELLATE SPECIES USING ITS rDNA SEQUENCES1
R. Wayne Litaker,Mark W. Vandersea,Steven R. Kibler,Kimberly S. Reece,Nancy A. Stokes,François Lutzoni,Bryan Yonish,Melissa A. West,Megan N. D. Black,Patricia A. Tester +9 more
TL;DR: The results indicate that a between‐species uncorrected genetic distance of p could be used to delineate most free‐living dinoflagellate species, however, recently evolved species, may have ITS p values <0.04 and would require more extensive morphological and genetic analyses to resolve.
