15 صفحه اولThe End of a Myth: Arpylorus Antiquus Paleozoic Dinoflagellate Cyst
Arpylorus antiquus, erected by Calandra (1964), was isolated from Upper Silurian sedimentary rocks from the Mechiguig-1 borehole in southern Tunisia, with other palynomorphs. The folded vesicle and the quadrangular form of the aperture breaks down into plate-like fragments, resembling the tabulation of dinoflagellates. The presence of these elements, have been used to interpret A. antiquus as a...
متن کاملTowards 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 importance of palynology in the taxonomy of genus Silene, based on pollen morphology
In this study, the palynology of 33 species of Silene belonging to 15 sections was investigated to examine the correspondence between palynology, morphological sections and phylogenetic trees. The pollen grains were prepared using the acetolysis method. Quantitative and qualitative micromorphological features of pollens were investigated using light microscopy and scanning electron microscopy....

ABST RAC T : Observations with light and scanning electro n microscopes indicate the foliicolous chlorophyte Pf!ycopeltis baiuaiiensis King (Chroolepid aceae) is subcut icular and polystromatic, produces steri le hairs, and induces a distinct wounding, reaction in sub tending host tissue. In comparison , similar obse rvations on Pbycopeltis epiphyton and other P~ycopeltis species reveal that, a...
