New for the Black Sea Species Chaetoceros minimus (Bacillariophyta): Field Observations and Experimental Studies
要約
In the spring of 2005 in the north-east shelf of the Black Sea near the town of Gelendjik, a small cell diatom Chaetoceros minimus (Levander) Marino, Giuffre, Montresor et Zingone was recorded for the first time with maximum abundance (1.6·105 cell/L). In parallel, this species was revealed in the cultures of natural phytoplankton investigated in continuous culture. At the end of May 2006, in the period of intensive bloom of coccolithophore Emiliania huxleyi Lohm., Ch. Minimus was found in the north-eastern part of the Black Sea (4.4·105 cell/L). In June 2011 this invasive species abundantly grew in batch cultures of natural phytoplankton. Experimentally, it was shown that for abundant growth Ch. Minimus needs a relatively high concentration of phosphorus and low concentration of nitrogen. The maximal specific growth rate of Ch. Minimus is significantly higher than of E. huxleyi, which makes this invasive species potentially harmful to ecosystems.
