Última Intraspecific variation in alkaline phosphatase activity in Phaeodactylum tricornutum (Bacillariophyceae, Bohlin) Acta Botanica Lima,Domênica Teixeira de; Piedras,Fernanda Reinhardt; Nogueira,Flávia Previero; Richard,Eduardo da Cunha; Tocci,Bianca Reis Castaldi; Alba,Jose Juan Barrera; Moser,Gleyci Aparecida Oliveira. ABSTRACT To describe potential intraspecific variation in phosphorus incorporation in two strains of Phaeodactylum tricornutum (Bohlin), Ub3 and Ub7, alkaline phosphatase (AP) activity was evaluated via enzyme-labeled fluorescence assay. Analysis using the probe ELF-97(r) provides individual evaluation, and therefore can determine the nutritional status of inorganic phosphorus in phytoplanktonic cells. Bioassays compared the control treatment to both phosphate-enriched and phosphate-depleted treatments by varying only the phosphate concentration in the media. The P. tricornutum strains exhibited differences in their development when incubated in the phosphate-enriched media. The development of the Ub7 strain differed by exhibiting "luxury uptake" and...

Abstract: Most studies of Dinophysis acuminata in Brazil are for the southern region, where blooms are recurrent. In 2016, the presence of D. acuminata caused the first-ever production and consumption of species of mollusks commercial embargo from the state of Sao Paulo, Southeast Brazil. Potentially toxic species of Dinophysis have been reported in Guanabara Bay (GB) but only occasionally and in low densities. The present note is the first report of a high-density event (~105 cells L-1) of D. acuminata/D. sacculus complex in GB. D. acuminata/D. sacculus complex species were identified using scanning-electron and inverted-light microscopy. Most of the studied cells possessed a dorsally convex hyposomal plate and had dimensions typical of D. acuminata....
