Palynomorphs of brackish and marine species in cores from the freshwater Lake Sapanca, NW Turkey [PDF]

, 2010
Lake Sapanca, which is located on the Sakarya–Sapanca–İzmit corridor in NW Turkey, is a freshwater lake with numerous fish farms in its catchment. Palynological analyses including non-pollen palynomorphs of a short (38.5 cm) and a longer sediment core ...

From hystrichospheres to dinoflagellate cysts: Scandinavian contributions to Evitt’s pivotal recognition of fossil dinoflagellate cysts [PDF]

Palynology, 2020
As one of the remaining living links with two early Scandinavian researchers, the author examines their contribution to Bill Evitt’s breakthrough that launched the development of fossil dinoflagellate cysts into palynology. Evitt, in the early 1960s, revealed that many fossil hystrichospheres were in fact dinoflagellate cysts.

Mapping distribution of cysts of recent dinoflagellate and Cochlodinium polykrikoides using next-generation sequencing and morphological approaches in South Sea, Korea

Scientific Reports, 2018
The total dinoflagellate cyst community and the cysts of Cochlodinium polykrikoides in the surface sediments of South Sea (Tongyeong coast), South Korea, were analysed using next-generation sequencing (NGS) and morphological approaches.

Environmental factors influencing the variability of Lingulodinium polyedrum and Scrippsiella trochoidea (Dinophyceae) cyst production

Ciencias Marinas, 2009
This study analyzes the temporal variability of the abundance of Lingulodinium polyedrum and Scrippsiella trochoidea resting cysts in surface sediments, as well as the temporary cysts and vegetative cells of L.

New evidence for the age of the Athol Formation (Middle Jurassic : Bajocian) in the Tusk-1 and Tusk-2 wells, offshore Carnarvon Basin, Western Australia [PDF]

, 2010
The co-occurrence of ammonites with palynomorphs in the Athol Formation of the Tusk-1 and Tusk-2 wells drilled in the offshore Carnarvon Basin, Western Australia confirms the Early Bajocian (Middle Jurassic) age of the Dissiliodinium caddaense ...

Dinoflagellates, their cysts and Quaternary stratigraphy [PDF]

New Phytologist, 1988
summaryDinoflagellates are described, with particular emphasis on their feeding strategies and role within the phytoplankton. The potential ecological value of the fossilizable hypnozygotic cyst in reconstructing the climate throughout the Quaternary marine record is noted.

Dinoflagellate Cyst Distribution in Relation to the Sediment Composition and Grain Size in the Coastal Area of Pangkajene, South Sulawesi, Indonesia

Ilmu Kelautan, 2022
Dinoflagellate cysts have an important role for their bloom dynamics, which are commonly deposited along fine sediment grains and become the source of the next bloom. This study aimed to describe the cyst banks species composition, and their relationship

Differences in the chemical composition of organic-walled dinoflagellate resting cysts from phototrophic and heterotrophic dinoflagellates [PDF]

, 2013
Dinoflagellates constitute a large proportion of the planktonic biomass from marine to freshwater environments. Some species produce a preservable organic-walled resting cyst (dinocyst) during the sexual phase of their life cycle that is an important ...
