Desmocysta hadra, a new Late Cretaceous dinoflagellate cyst species: stratigraphic range, palaeogeographic distribution and palaeoecology [PDF]

Journal of Micropalaeontology, 2020
A new species of dinoflagellate cyst, Desmocysta hadra sp. nov., is described from the early Campanian (Late Cretaceous) in the Norwegian Sea. This new taxon differs from the other three known species by its particularly robust but highly folded wall and

Inhibitory effects of the brown macroalga Turbinaria ornata on cyst germination and progeny cells of five harmful dinoflagellate species

Oceanologia, 2022
This study investigates the inhibitory effects of thalli and their extracts of the macroalga Turbinaria ornata on the germination of dinoflagellate cysts, previously isolated from Red Sea surface sediments. The experiments were conducted on cysts of five

Filter feeding by oysters reduces disease transmission in a marine host-parasite system. [PDF]

Ecology
Abstract As a mechanism of the dilution effect, predation and filter feeding on parasitic propagules are hypothesized to reduce transmission to susceptible hosts and alter host–parasite interactions. In marine systems, the effect of other community members on the disease dynamics of microparasites in their suitable hosts is poorly known.
