Despite this trophic linkage, the temporal dynamics of cryptophyte-<i>Mesodinium-Dinophysis</i> remain poorly understood. In this study, we present the first <i>Teleaulax-Mesodinium-Dinophysis</i> (TMD)-complex system dynamics model. Using this, we explored the dynamics of TMD interactions under different ecological settings. Temperature, nutrient load, mixed layer depth, and irradiance all greatly influenced the timing and magnitude of the TMD-complex interactions and, as a result, <i>Dinophysis</i> bloom duration and peak. Availability of <i>Mesodinium</i> and temporal matching of its growth to that of <i>Dinophysis</i> are also key biotic factors; the timing of <i>Mesodinium</i> availability impacts the potential of <i>Dinophysis</i> growth for up to 3 months. Integrating our TMD-complex model with a suitable hydrodynamic model could greatly improve our understanding of bloom formation and aid in forecasting harmful algal bloom (HAB) events. Future monitoring of <i>Dinophysis</i> would also be enhanced by the monitoring of the precursor prey species, <i>Teleaulax</i> and <i>Mesodinium</i>, which are rarely accorded the same effort as the HAB forming dinoflagellate.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Acquired phototrophy and its implications for bloom dynamics of the <i>Teleaulax-Mesodinium-Dinophysis</i>-complex","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-26 01:32:09.047399","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"mixoplankton; harmful algal blooms; HABs; systems dynamics modeling; predator-prey; TMD-complex; trophic dynamics","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-06-21","DateCreate":"2022-06-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000760818900001","VABBcode":null,"OpenAcc":1,"DOI":"10.3389/fmars.2021.799358"},"refs":null,"anarec":{"AnaID":352749,"PubliDate":2022,"Pagination":"799358","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":233602,"SerRR":"Frontiers in Marine Science.
