Raphidophyceae [Chadefaud Ex Silva] Systematics And Rapid Identification: Sequence Analyses And Real–Time Pcr Assays, Torstein Tengs
Raphidophyceae [Chadefaud Ex Silva] Systematics And Rapid Identification: Sequence Analyses And Real–Time Pcr Assays, Torstein Tengs
Dr. Torstein Tengs
Species within the class Raphidophyceae were associated with fish kill events in Japanese, European, Canadian, and U.S. coastal waters. Fish mortality was attributable to gill damage with exposure to reactive oxygen species (peroxide, superoxide, and hydroxide radicals), neurotoxins, physical clogging, and hemolytic substances. Morphological identification of these organisms in environmental water samples is difficult, particularly when fixatives are used. Because of this difficulty and the continued global emergence of these species in coastal estuarine waters, we initiated the development and validation of a suite of real-time polymerase chain reaction (PCR) assays. Sequencing was used to generate complete data sets for …
A Group Of Dinoflagellates Similar To Pfiesteria As Defined By Morphology And Genetic Analysis, Torstein Tengs
A Group Of Dinoflagellates Similar To Pfiesteria As Defined By Morphology And Genetic Analysis, Torstein Tengs
Dr. Torstein Tengs
Eight novel pfiesteria-similar dinoflagellates are described that form a genetically well-defined group with distinct morphological features, and are capable of feeding myzocytotically on cryptophytes and other algae. Taxonomically, there was concordance between the genetic analysis and plate tabulation features among these taxa. It is suggested that these dinoflagellates are important grazers of other phytoplankton in the environment, and their total ecological significance has been underestimated.
