Dinocysts
WebDinocysts have also proved useful as a proxy for the dinoflagellate contribution to sedimentary organic matter. They consist of organic-walled capsules composed of a highly refractory aliphatic biomacropolymer (dinosporin, Kokinos et al. 1998). Dinocysts protect the cell during the dormancy, or ‘‘hypnozygote’’ phase, of many dinoflagellate WebNov 1, 2013 · Dinocysts as proxy of primary productivity in mid-high latitudes of the Northern Hemisphere Marine Micropaleontology (2008) W.R.

Dinocysts also record an earliest Danian transgressive event 10 cm above the transition interval. WebJun 22, 2024 · Dinoflagellate cysts (hereafter referred to as dinocysts) help the population survive from the harsh environment, and the germination of cysts provides large amounts of vegetative cells to the water column. Therefore, dinocysts are considered as the “seed bank” for the occurrence of HAB (Anderson et al., 2014; Castaneda-Quezada et al., 2024).
