Temporal changes in the cyst densities of Pyrodinium bahamense var. compressum and other dinoflagellates in Manila Bay, Philippines
چکیده انگلیسی

Temporal variation in the type and abundance of dinoflagellate cysts in Manila Bay, Philippines, is established using 210Pb-dated sediment cores. At least 17 dinoflagellate cyst species, including those of the toxic species, Pyrodinium bahamense var. compressum, were identified. P. bahamense may have been present in the area since at least the 1920s. Total cyst density has increased beginning about 1988 to 1998 coinciding with records of P. bahamense blooms in the area. Heterotrophs have always dominated the cysts assemblage. These changes in the dinoflagellate record and the P. bahamense blooms in recent years may have been induced by the interplay of warmer temperatures, high rainfall leading to higher river discharge and less turbulent waters due to passage of few tropical cyclones.
