“…Dinocysts are known to reflect anthropogenic changes and few studies have tried to link dinocyst distribution pattern to different pollution types. Most studies focused on the effect of nutrient enrichment on the dinoflagellate community and the potential of organic-walled dinoflagellates as eutrophication indicators in coastal waters (e.g., Dale and Fjellså, 1994;Dale et al, 1999;Dale, 2001Dale, , 2009Pospelova et al, 2002Pospelova et al, , 2004Matsuoka et al, 2003;Sangiorgi and Donders, 2004;Pospelova and Kim, 2010;Kim et al, 2012;Tian et al, 2018), although few areas were studied testing the effects of industrial pollution (e.g., Saetre et al, 1997;Dale, 2001;Pospelova et al, 2005;Liu et al, 2012;Aydin et al, 2015;Triki et al, 2017). Numerous studies showed that eutrophication signal can be identified by increased dinocyst concentrations in sediments along with nutrient input increases (Dale and Fjellså, 1994;Dale et al, 1999;Matsuoka, 1999;Persson et al, 2000;Pospelova et al, 2005;Rabalais et al, 2009;Liu et al, 2012;Zonneveld et al, 2012).…”

Dinoflagellates are part of the marine plankton and about 200 species produce a cyst (dinocyst) during their life cycle, these organic-walled sexually-produced cysts being fossilizable in sediments for hundreds of millions of years. Over the past 40-50 years, dinocysts have led to major advances on Mesozoic-Cenozoic research, in terms of biostratigraphy and paleogeogeography. Dinocyst taxonomy has then been continuously revised, with the tabulation being the main morphological link between living dinoflagellates and fossilized cysts. Over the Quaternary, and based on the principle of uniformitarianism (i.e. species ecology did not change through time), relationships between modern assemblages and present-day environmental factors controlling their distribution also allow for dinocystbased quantitative reconstructions derived from transfer function calculations. This paper presents a non-exhaustive review of the dinocyst literature allowing the reader to get a perspective about how they were discovered and defined, but also how they are applied in (paleo)ecological studies according to the timescale considered allowing then to provide useful insights into the future climate change and its associated ecological repercussions.

“…surface salinity, temperature, nutrients). Dinoflagellate cysts have become a valuable proxy both as an effective biological indicator and also for investigating past environmental changes due to the encystment of dinoflagellate species in the sea, which is mainly affected by environmental changes and nutrient enrichments (Marret and Zonneveld, 2003;Pospelova and Kim, 2010;Kim et al, 2012;Zonneveld et al, 2013).…”

Harmful algal blooms (HAB) are a phenomenon of drastically increasing phytoplankton populations, which can cause problems in aquatic ecosystems. Dinoflagellate cysts are a type of phytoplankton that are the main source of causing the HAB phenomenon; this occurs due to unfavorable environmental conditions. The Southern Estuary of South Sulawesi has high fishery resources and high primary productivity. The coastal areas around these waters are widely used for anthropogenic activities that trigger nutrient increases. There are no studies on HAB, especially the abundance and community structure of dinoflagellate cysts at this location. This study aims to identify the types, abundance, and species assemblages of dinoflagellate cysts in the three estuaries of southern South Sulawesi. Sampling was carried out at three locations, namely the Pappa River Estuary, the Kelara River Estuary, and the Calendu River Estuary, in January 2022. Each location consists of 4 stations, 3 sub-stations with 3 repetitions sampling for each substation. Results showed that there were 34 species of dinoflagellate cysts belonging to 6 families, namely Gonyaulacaceae, Gymnodiniaceae, Osteropsidaceae, Peridiniaceae, Polykrikaceae, and Protoperidiaceae. The highest abundance of dinoflagellate cysts was at the Calendu River estuary station III, accounting for 82 cysts g−1, while the lowest abundance of dinoflagellate cysts was found at Pappa River estuaries stations I and II, accounting for 8 cysts g−1. The level of diversity, uniformity, and richness of dinoflagellate cysts was not significantly different in the three study sites. The family Osteropsidaceae was the most common type of dinoflagellate cyst found in the three study sites. The Osteropsidaceae family is a type of dinoflagellate cyst that contains toxins, so it can be assumed that the three research sites have the potential for HAB.
