Towards an Ecological Understanding of Dinoflagellate Cyst Functions
The life cycle of many dinoflagellates includes at least one nonflagellated benthic stage (cyst). In the literature, the different types of dinoflagellate cysts are mainly defined based on morphological (number and type of layers in the cell wall) and functional (long- or short-term endurance) differences. These characteristics were initially thought to clearly distinguish pellicle (thin-walled...
متن کاملThe life history and cell cycle of Kryptoperidinium foliaceum, a dinoflagellate with two eukaryotic nuclei.
Kryptoperidinium foliaceum is a binucleate dinoflagellate that contains an endosymbiont nucleus of diatom origin. However, it is unknown whether the binucleate condition is permanent or not and how the diatom nucleus behaves during the life history processes. In this sense, it is also unknown if there is a sexual cycle or a resting stage during the life history of this species, two key aspects ...
متن کاملDinoflagellate cysts from the Upper Triassic (Rhaetian) strata of the Tabas Block, East - Central Iran
Rhaetian strata from the Nayband Formation of the Tabas block, East- Central Iran, were studied palynologically. The materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofRhaetogonyaulax rhaetica Zone. The assigned age of this dinozone (Rhaetian) is justified by plant fossils such as Equisetitesarenaceus, Scytophyllum...

متن کاملRapid growth and concerted sexual transitions by a bloom of the harmful dinoflagellate Alexandrium fundyense (Dinophyceae)
Transitions between life cycle stages by the harmful dinoflagellate Alexandrium fundyense are critical for the initiation and termination of its blooms. To quantify these transitions in a single population, an Imaging FlowCytobot (IFCB), was deployed in Salt Pond (Eastham, Massachusetts), a small, tidally flushed kettle pond that hosts near annual, localized A. fundyense blooms. Machine-based i...
