“…This is the only comprehensive research for pigments using a HPLC that dealt with both peridinin-type dinoflagellates and dinotoms, which allows us to compare to our results. Most of common pigments of both dinoflagellate types in this study (PCPe and PCDi) are corresponding with detected pigments in Zapata et al (2012). However, the number of detected pigments in this study greatly exceeds that of Zapata et al (2012).…”

However, the number of detected pigments in this study greatly exceeds that of Zapata et al (2012). Most of such additional pigments reported here, including cPPB-aE, chl c 3 and many UCs, have never been detected from peridinin-type dinoflagellates and dinotoms.…”

“…Recently Zapata et al (2012) reported pigment compositions of 64 dinoflagellate species (122 strains). This is the only comprehensive research for pigments using a HPLC that dealt with both peridinin-type dinoflagellates and dinotoms, which allows us to compare to our results.…”

“…This typical chloroplast type in dinoflagellate called 'peridinin-type'. In contrast, some groups of dinoflagellates have replaced their peridinin-type chloroplasts with one from other microalgae, belonging to Haptophyta (Tengs et al 2000, Zapata et al 2012, Chlorophyta (Watanabe et al 1990, Matsumoto et al 2012 or Bacillariophyta (diatoms) (Riley and Wilson 1967, Chesnick et al 1997, Takano et al 2008, Zhang et al 2011, Zhang et al 2014). …”

“…From this result, we came to an idea that habitat selection might be linked to pigment compositions. Although recently Zapata et al (2012) reported pigment compositions of 64 dinoflagellate species, including wide taxonomic groups, little attention was made to relate pigment profiles and habitat types. Therefore, to date, no comprehensive studies relating pigment composition to habitat types have not been available.…”

Pigment compositions are linked to the habitat types in dinoflagellates

Compared to planktonic species, benthic dinoflagellates living in sandy beach or seafloor are a little known about ecology, physiology, even their existences. In a previous study, we discovered 13 2 ,17 3 -cyclopheophorbide a enol (cPPB-aE) from sand-dwelling benthic dinoflagellates. This enol had never been detected in phytoplankton despite it is a chlorophyll a catabolite. We speculated from this discovery that habitat selection might be linked to pigment compositions in dinoflagellates. To test the hypothesis of habitat selection linking to pigment compositions, we conducted extensive analysis of pigments with high performance liquid chromatography (HPLC) for 40 species using 45 strains of dinoflagellates including three habitat types; sand-dwelling benthic forms, tidal pool inhabitants and planktonic species.Those 40 dinoflagellates are also able to distinguished into two types based on their chloroplast origins; red alga-derived secondary chloroplasts and diatom-derived tertiary ones.By plotting the pigments profiles onto three habitats, we noticed that twelve pigments including cPPB-aE were found to occur only in benthic sand-dwelling species of red alga-derived type. The similar tendency was also observed in dinoflagellates with diatom-derived chloroplasts, i.e. additional sixteen pigments including chl c 3 were found only in sand-dwelling forms. This is the first report of the occurrence of chl c 3 in dinoflagellate 3 with diatom-derived chloroplasts. These results clarify the far greater diversity of pigments are produced by the dinoflagellates living in sand regardless of chloroplast types relative to those of planktonic and tidal pool forms. Dinoflagellates seem to produce a part of their pigments in response to their habitats.

A new approach to discriminate dinoflagellate from diatom blooms from space in the East China Sea

Dinoflagellate and diatom blooms often occur in the East China Sea (ECS) during spring and summer. Some of the dinoflagellate blooms are toxic, resulting in widespread economic damage. In order to mitigate the negative impacts, remote-sensing methods that can effectively and accurately discriminate between bloom types are demanded for early warning and continuous monitoring of bloom events at large scales. An in situ bio-optical data set collected from diatom and dinoflagellate blooming waters indicates that the two types of blooms exhibited distinctive differences in the shapes and magnitudes of remotesensing reflectance (R rs ). The ratio of in situ measured R rs spectral slopes at two spectral ranges (443-488 and 531-555 nm, bands available with the moderate resolution imaging spectrometer (MODIS) sensor), abbreviated as BI (representing bloom index), was found effective in differentiating dinoflagellates from diatoms. Reflectance model simulations, which were carried out using in situ and algal culture data as input, provided consistent results. A classification approach for separating dinoflagellate from diatom blooms in the ECS was then developed: When fluorescence line height (FLH) is doubled over the background level and total absorption coefficient at 443 nm ! 0.5 m 21 , if 0.0 < BI 0.3, it suggests a dinoflagellate bloom; if 0.3 < BI 1.0, it suggests a diatom bloom. Finally, the approach was applied to MODIS measurements over the ECS, and a series of diatom and dinoflagellate bloom events during April-June 2005 and 2011 were successfully identified, suggesting that the proposed approach is generally valid for the ECS.
