Pelagic primary production in the coastal Mediterranean Sea: variability, trends, and contribution to basin-scale budgets

Paula Maria Salgado-Hernanz et al.

Summary: We estimated the pelagic primary production in the coastal Mediterranean Sea and found that it contributes approximately 12% of the total carbon fixation in the region. The eastern basin has the highest production, followed by the western and Adriatic shelves. There is strong regional variability in coastal primary production, with some areas having high productivity associated with major river discharges and others having lower productivity in the southeastern Mediterranean. While interannual variations dominate the variability, a significant decline in primary production has been observed since 2012, coinciding with increasing sea surface temperatures and positive climate indices. Long-term trends show slight declines in most coastal areas except for the Adriatic, where primary production is increasing. The study emphasizes the importance of temporal and spatial scales of variability and provides insight into the contribution of coastal waters to the carbon balances in the Mediterranean Sea.

Feeding diverse prey as an excellent strategy of mixotrophic dinoflagellates for global dominance

Hae Jin Jeong et al.

Summary: Research has shown that mixotrophic dinoflagellates play a significant role in global red tide events due to their ability to combine photosynthesis and predation. Species with low to moderate growth rates, but diverse prey, including diatoms, are responsible for causing red tides worldwide, indicating a strategy of exchanging growth for prey diversity.

Ecophysiology of the kleptoplastidic dinoflagellate Shimiella gracilenta: I. spatiotemporal distribution in Korean coastal waters and growth and ingestion rates

Jin Hee Ok et al.

Summary: Through studying the ecophysiological characteristics of the kleptoplastidic dinoflagellate Shimiella gracilenta in Korean coastal waters, it was found that the species has a common spatiotemporal distribution, feeds on diverse prey species, and shows relatively low abundance during the study period. When feeding on its optimal prey species Teleaulax amphioxeia, S. gracilenta exhibits high maximum specific growth and ingestion rates.

First Concurrent Measurement of Primary Production in the Yellow Sea, the South Sea of Korea, and the East/Japan Sea, 2018

Hyo-Keun Jang et al.

Summary: This study utilized the C-13-N-15 tracer method to measure primary productions in the Yellow Sea, the South Sea of Korea, and the East/Japan Sea for the first time in 2018. The research found that primary productivity levels varied among the three seas, with smaller phytoplankton having a significant negative impact on primary production, especially under warming ocean conditions.

Comparison of the spatial-temporal distributions of the heterotrophic dinoflagellates Gyrodinium dominans, G. jinhaense, and G. moestrupii in Korean coastal waters

Sung Yeon Lee et al.

Summary: Heterotrophic dinoflagellates Gyrodinium spp. are major grazers of phytoplankton in coastal waters. Through a study on their spatial-temporal distributions in Korean waters, it was found that the three Gyrodinium species, despite similar morphologies, had different abundances and seasonal distributions, suggesting potential differences in ecological niches. This contrasts with previous studies based on genetic sequences and prey preferences.

Interactions between common heterotrophic protists and the dinoflagellate Tripos furca: implication on the long duration of its red tides in the South Sea of Korea in 2020

Se Hee Eom et al.

Summary: The mixotrophic dinoflagellate Tripos furca is responsible for red tides in various countries. This study investigated the interactions between T. furca and different heterotrophic dinoflagellates and a naked ciliate. Results showed that some heterotrophic dinoflagellates can feed on T. furca, but T. furca cannot support their growth; moreover, the long duration of T. furca red tides in the South Sea of Korea in 2020 may be partially attributed to the absence of effective predators.

Spatiotemporal change in coastal waters caused by land-based fish farm wastewater-borne nutrients: Results from Jeju Island, Korea

Yong Hwa Oh et al.

Summary: The study revealed that organic matter from fish farm wastewater may be a major source of pollution in seawater, while inorganic nutrients from wastewater are effectively removed through biological processes. The flux of organic matter from wastewater in the coastal waters of Jeju Island is comparable to that from submarine groundwater.
