Dinoflagellate cysts as proxies of environmental, ocean and climate changes in the Atlantic realm during the quaternary

Frontiers in Ecology and Evolution
Over the last four decades, organic-walled dinoflagellate cysts have shown high potential as tracers of past sea-surface conditions during the Quaternary.

The age of the Tojeira Formation (Late Jurassic, Early Kimmeridgian), of Montejunto, west-central Portugal [PDF]

, 2017
Precise biostratigraphic dating of the Tojeira Formation (Late Jurassic, Early Kimmeridgian) of the Montejunto section of west-central Portugal, which has yielded important planktonic foraminiferal assemblages, is hindered by poor preservation in the ...

Marine Cretaceous organic-walled dinoflagellate cysts from the Austral-Magallanes Basin.

Latin American Journal of Sedimentology and Basin Analysis, 2021
Cretaceous marine sedimentary rocks from the Austral-Magallanes Basin have provided a valuable organic-walled dinoflagellate cyst record as a useful tool for biostratigraphical interpretations and paleo-oceanographical reconstructions.

Suppression of cyst germination success in Gymnodinium catenatum and Ostreopsis cf. ovata by macroalgal extracts from the southern Mediterranean Sea

Oceanological and Hydrobiological Studies
This study examines the potential inhibitory effects of extracts of seven Mediterranean macroalgae on the germination success of two harmful dinoflagellate cysts, Gymnodinium catenatum and Ostreopsis cf. ovata.

The Marmara Sea Gateway since ~16 ky BP: non-catastrophic causes of paleoceanographic events in the Black Sea at 8.4 and 7.15 ky BP [PDF]

, 2007
The Late Quaternary history of connection of the Black Sea to the Eastern Mediterranean has been intensely debated. Ryan, Pitman and coworkers advocate two pulses of outflow from the Black Sea to the world ocean at ~16–14.7 ky BP and ~11–10 ky BP ...

Study on dinoflagellate cysts of Holocene and their environmental significance in Bohai Sea [PDF]

, 2016
甲藻是一种非常古老的真核生物，许多甲藻能产生休眠孢囊。沉积物中的甲藻休眠孢囊对反映海水温度、盐度、营养盐及海平面变化等环境因子具有非常重要的意义，其还可以揭示赤潮发生的潜能。渤海是我国半封闭的内海，受地形地貌、气候、海洋水文及人类活动影响较为显著。本文对渤海表层及柱状沉积物中的甲藻孢囊进行研究，表层样结合现代数理统计软件细致地分析了甲藻孢囊的种类组成、分布特征及与环境因子的关系。柱状样结合地层年代通过优势种在各层位的含量变化，探讨了渤海近8000aBP年以来海水的温度、盐度 ...
