Species axis 1 was positively correlated with SD and
Chrysophyta biomass but negatively correlated with TP (Fig.
(a) Chlorophyta 42.3% Bacillariophyta 19.2% Pyrrophyta 2.6% Xanthophyta 2.6% Euglenophyta 9.0% Cryptophyta 6.4% Cyanophyta 14.1%
Chrysophyta 3.8% (b) Chlorophyta 52.3% Bacillariophyta 5.5% Pyrrophyta 2.8% Xanthophyta 1.8% Euglenophyta 13.8% Cryptophyta 3.7% Cyanophyta 19.3%

Silica-scaled Chrysophyceae and Synurophyceae (
Chrysophyta) from Mississippi.
The cyanobacteria accounted for ten species, followed by the Chlorophyta with four species and the
Chrysophyta with one species.
The Lake Daihai is a typical algal-dominated lake, and there are about 121 species and 76 genera of algae of which belong to Chlorophyta (28 genera), Bacillariophyta (21 genera), Cyanophyta (9 genera), Euglenophyta (7 genera), and other algae including Pyrrophyta, Cryptophyta, and
Chrysophyta [30].
Spatial-temporal variation in phytoplankton: The phytoplankton was made up of 53 species and one variety: Chlorophyta (45.28%), Cyanophyta (30.19%), Bacillariophyta (15.09%), Euglenophyta (3.77%), Cryptophyta (3.77%) and
Chrysophyta (1.89%).
La mayor diversidad fue observada en Chlorophyta, seguido por Bacillariophyta y Cyanophyta, mientras que Rhodophyta, Pyrrhophyta y
Chrysophyta presentaron valores minimos (Tabla 2).
Moreover, remarkable level of flagellate biomarker in both species suggested the importance of flagellates (mainly including species in
Chrysophyta and Pyrrophyt) in the diet of two intertidal bivalves.
Chapman considers the haptophytes or prymnesiophytes, and diatoms or Bacillariophyta as two independent types of protoctists, and includes the silicoflagellates as a class within the
Chrysophyta (also considered as a separate phylum), called the Dictyochophyceae.

Chrysophyta and Cryptophyta taxa dominated the phytoplankton at the start of the experiment in all enclosures and throughout the summer in the control enclosures ([ILLUSTRATION FOR FIGURE 4 OMITTED], Plate 1, Appendix I).
Zygnemaphyta was the most specious group (94 taxa), followed by Chlorophyta (77 taxa), Bacillariophyta (71 taxa), Cyanophyta (20 taxa), Euglenophyta (12 taxa),
Chrysophyta (5 taxa), Dinophyta (2 taxa), Cryptophyta (1 taxa) and Xanthophyta (1 taxa).
