SUMMARY Cellular morphology and the phylogenetic position of a new unarmored photosynthetic dinoflagellate Cochlodinium fulvescens Iwataki, Kawami et Matsuoka sp. nov. were examined by light microscopy molecular analyses based on partial large subunit ribosomal DNA (LSU rDNA) small (SSU sequences. The cells C. closely resemble polykrikoides , one most harmful red tide forming dinoflagellates, due to it possessing cingulum encircling cell approximately twice, spherical nucleus positioned in...
Abstract Process length variation of cysts the dinoflagellate Protoceratium reticulatum (Claparède et Lachmann) Bütschli in surface sediments from North Pacific was investigated. The average process showed a significant inverse relation to annual seawater density: σ t = −0.8674 × + 1029.3 ( R 2 0.84), with standard error 0.78 kg m −3 . A sediment trap study Effingham Inlet British Columbia revealed same relationship between and local density variations. In Baltic–Skagerrak region, related...
Abstract. Surface sediments were collected from 10 locations to study the distribution of dinoflagellate resting cysts in Chinese coastal waters July 2000 May 2002. Sixty‐one cyst morphotypes representing 14 genera three orders identified this survey. Seventeen types recorded for first time coasts. Rich assemblages closed or semi‐closed nearshore harbors. Scrippsiella trochoidea was most dominant and common type survey, especially Daya Bay, Dapeng Bay Shenzhen Bay. However, Protoperidinium...
Red tide, one of the harmful algal blooms (HABs) is a natural ecological phenomenon and often this event accompanied by severe impacts on coastal resources, local economies, public health. The occurrence red tides has become more frequent in Omani waters recent years. Some them caused fish kill, damaged fishery resources mariculture, threatened marine environment osmosis membranes desalination plants. However, number have been harmless. most common dinoflagellate Noctiluca scintillans...

This study provides the first morphological features of resting cysts Cochlodinium polykrikoides collected from Korean coastal sediments. Evidence for existence C. is based on and molecular phylogenetic data germinated cells a cyst. The morphology differed that reported previously in sediments culture experiments. distinct feature cyst body was covered by reticulate ornaments spines.
A new unarmoured dinoflagellate, Karenia digitata Yang, Takayama, Matsuoka & Hodgkiss sp. nov., is described on the basis of light and electron microscopy. It has bloomed in Hong Kong Japan, caused significant fish kills financial loss. High ichthyotoxicity persisted for approximately one week after blooms had subsided. cells are 10–26.25 μm long 10–22.5 wide. The epicone hemispherical or broadly conical; hypocone not concave at antapex. girdle displacement varies but more than 20% body...
