Can increases in temperature stimulate blooms of the toxic benthic dinoflagellate Ostreopsis ovata?

A Pilot Study on the Effects of Temperature on the Blooms of the Benthic Mucilage-Forming Microalga Chrysophaeum taylorii

“…This hypothesis is strongly supported by the data collected in the present study, highlighting the importance of temperature in C. taylorii abundance, as already proved for other similar species [5,6] and recently also suggested by Caronni et al [18] for the above-mentioned microalga. C. taylorii cells reached the maximum density on the substratum near the powerhouse (S 1 ), where the sea water temperature was close to 30 °C, and gradually decreased distancing from it along the considered temperature gradient.…”

“…With regard to microalgae, in particular, as sea water temperature is currently considered as one of the main environmental factors determining the abundance and composition of microphytobenthos on the substratum [2][3][4][5], climate changes seem to be among the major driving forces behind the stimulation, distribution and intensification of their blooms in the last decades [6]. Indeed, warmer sea water temperatures result in expanded ranges of warm water microalgal species, which blooms at latitudes higher than their original ones seem to be almost completely temperature-dependent [5].…”

Potentiality of benthic dinoflagellate cultures and screening of their bioactivities in Jeju Island, Korea

“…In addition, growth rate of 0.15 to 0.25 divisions day -1 is similar to growth rate of 0.22 divisions day -1 mentioned by Nascimento et al (2012). However, it was lower than 0.53 divisions day -1 (Guerrini et al, 2010), 1.07 divisions day -1 (Granéli et al, 2011) and 1.03 divisions day -1 (Yamaguchi et al, 2012). Dason and Colman (2004) ) for 24 h, the NO levels in the medium was measured.…”

Dinoflagellates: Ecological Approaches and Spatial Distributions in Malaysia Waters

“…The high temperature is favorable for benthic species and it is further verified when there is no blooming reported during winter [23]. An experimental study by Granéli et al [24] concluded that elevated sea temperature was stimulating the bloom of Ostreopsis ovata in Brazil and Italy. The species grew well beyond 26ºC with the influence of other promoting factors.…”
