Climate Change Drives Long-Term Spatiotemporal Shifts in Red Noctiluca scintillans Blooms Along China's Coast.

Climate change has significantly altered the spatiotemporal distribution and phenology of marine organisms, yet the long-term trends and mechanisms driving these changes remain insufficiently understood. In this study, we analysed historical Noctiluca scintillans bloom data from coastal China (1933, 1952, 1981-2023), sea surface temperature (SST) records from the past 40 years, and 509 field samples using Single Molecule Real-Time (SMRT) sequencing (2019-2024). Our results indicate that SST is the primary driver of N.

Morphology, phylogeny, and toxicity of three Gambierdiscus species from the South China Sea, including a coral-killing bloom of G. carpenteri in reef tanks.

Gambierdiscus is a genus of benthic dinoflagellate commonly found in coral reef ecosystems. Some species produce neurotoxins, such as ciguatoxins (CTXs) and maitotoxins (MTXs), which have been linked to ciguatera poisoning (CP), an illness prevalent in tropical regions. In this study, three Gambierdiscus species, G.

Biogeochemical factors regulating photosynthetically dissolved organic carbon produced by phytoplankton in the Taiwan Strait.

The distribution and mechanisms of photosynthetically dissolved organic carbon (PDOC) released by marine phytoplankton are frequently neglected and inadequately understood because most studies on carbon sequestration capacity have focused on photosynthetic particulate organic carbon. In this study, percentage extracellular release (PER) and its environmental influencing factors were investigated for 10 cruises in the Taiwan Strait during 2006-2023. The results indicated that the PER increased horizontally from the nearshore to the off-shelf and vertically from the surface to the bottom within the euphotic zone.
