interactions between the mixotrophic dinoflagellate takayama helix and common heterotrophic protists. | the phototrophic dinoflagellate takayama helix that is known to be harmful to abalone larvae has recently been revealed to be mixotrophic. although mixotrophy elevates the growth rate of t. helix by 79%-185%, its absolute growth rate is still as low as 0.3d-1. thus, if the mortality rate of t. helix due to predation is high, this dinoflagellate may not easily prevail. to investigate potential effective protistan grazers on t. helix, feeding by diverse heterotrophic dinoflagellates such as engulf ... | 2017 | 28962979 |
mixotrophy in the marine red-tide cryptophyte teleaulax amphioxeia and ingestion and grazing impact of cryptophytes on natural populations of bacteria in korean coastal waters. | cryptophytes are ubiquitous and one of the major phototrophic components in marine plankton communities. they often cause red tides in the waters of many countries. understanding the bloom dynamics of cryptophytes is, therefore, of great importance. a critical step in this understanding is unveiling their trophic modes. prior to this study, several freshwater cryptophyte species and marine cryptomonas sp. and geminifera cryophila were revealed to be mixotrophic. the trophic mode of the common ma ... | 2017 | 28962973 |
