“…This work represents a preliminary attempt to evaluate the ability of the filter feeder polychaetes Sabella spallanzanii and Branchiomma luctuosum to remove, in relation to their filtration process, a microalgal potentially toxic species, such as Amphidinium carterae, representing a danger to human health when present at high concentrations in seawater [36][37][38].…”

Filtration of the Microalga Amphidinium carterae by the Polychaetes Sabella spallanzanii and Branchiomma luctuosum: A New Tool for the Control of Harmful Algal Blooms?

Harmful algal blooms (HABs) are extreme biological events representing a major issue in marine, brackish, and freshwater systems worldwide. Their proliferation is certainly a problem from both ecological and socioeconomic contexts, as harmful algae can affect human health and activities, the marine ecosystem functioning, and the economy of coastal areas. Once HABs establish, valuable and environmentally friendly control actions are needed to reduce their negative impacts. In this study, the influence exerted by the filter-feeding activity of the two sabellid polychaetes Branchiomma luctuosum (Grube) and Sabella spallanzanii (Gmelin) on a harmful dinoflagellate was investigated. Clearance rates (C) and retention efficiencies were estimated by employing the microalga Amphidinium carterae Hulburt. The Cmax was 1.15 ± 0.204 L h−1 g−1 DW for B. luctuosum and 0.936 ± 0.151 L h−1 g−1 DW for S. spallanzanii. The retention efficiency was 72% for B. luctuosum and 68% for S. spallanzanii. Maximum retention was recorded after 30 min for both species. The obtained results contribute to the knowledge of the two polychaetes’ filtration activity and to characterize the filtration process on harmful microalgae in light of the protection of water resources and human health. Both species, indeed, were extremely efficient in removing A. carterae from seawater, thus suggesting their employment as a new tool in mitigation technologies for the control of harmful algae in marine environments, as well as in the aquaculture facilities where HABs are one of the most critical threats.

“…These genera were identified for the first time in these lagoon systems in the current study, and could pose a risk to the Indigenous communities in the region for whom artisanal fisheries are a primary source of subsistence. Some of the www.nature.com/scientificreports/ dinoflagellates found in the sediments, mostly present in C and previously identified in the North of the Mexican Pacific 76,78 , represent a risk for aquaculture activities (shrimp farming and the fattening of fishes in captivity), marine megafauna and human health 79,80 , such as Alexandrium leei, A. ostenfeldii, A. pohangense, Amphidinium klebsii, Prorocentrum triestinum, Lingulodinium polyedrum and Gonyaulax spinifera 77,78,81 . Other non-toxic and grazer dinoflagellates were found too, Gyrodinium jinhaense, Pellucidodinium psammophilum, and Nusuttodinium amphidinioides 82,83 .…”

Tropical coastal lagoons are important ecosystems that support high levels of biodiversity and provide several goods and services. Monitoring of benthic biodiversity and detection of harmful or invasive species is crucial, particularly in relation to seasonal and spatial variation of environmental conditions. In this study, eDNA metabarcoding was used in two tropical coastal lagoons, Chacahua (CH) and Corralero (C) (Southern Mexican Pacific), to describe the benthic biodiversity and its spatial–temporal dynamics. The distribution of benthic diversity within the lagoons showed a very particular pattern evidencing a transition from freshwater to seawater. Although the two lagoon systems are similar in terms of the species composition of metazoans and microeukaryotes, our findings indicate that they are different in taxa richness and structure, resulting in regional partitioning of the diversity with salinity as the driving factor of community composition in CH. Harmful, invasive, non-indigenous species, bioindicators and species of commercial importance were detected, demonstrating the reach of this technique for biodiversity monitoring along with the continued efforts of building species reference libraries.

“…In this study we detected three harmful species (Akashiwo sanguinea, Levanderina fissa and Margalefidinium fulvescens), one toxic (Gymnodinium catenatum) and two potentially bloom-forming species (Lepidodinium viride and Takayama tasmanica), for the rest of the species their effect is unknown. In Mexico, there have been several epizootics related to the flowering of A. sanguinea, the last reported event was in 2007, where this species possibly caused anoxic conditions (abundance of 4.6 × 10 3 cells/l), which caused the massive death of benthic species in the North of Baja California Sur [36] [37] [38]. Levanderina fissa has been recorded in high abundances (from 163 to 265 × 10 3 cells/l) in Bahía de la Paz, Mexico, although the blooms of this species were harmless for the area [39].…”

The Gymnodiniales are the most important group of athecate dinoflagellates both for its abundance and distribution and for the harmful potential of several of its species. Although morphologically it is well known, phylogenetically it has been very little studied. HABs impact important coastal activities in Todos Santos Bay, so a detailed characterization of potentially toxic phytoplankton species is crucial in monitoring surveys. Therefore, the aim of the present study was to carry out a molecular assessment to the morphospecies of Gymnodiniales currently recorded in Todos Santos Bay, from which discussed their phylogenetic relationships. 120 samples were obtained from monthly samplings during 2019 to 2020. For all of them, 18 s small subunit (SSU) and 28 s large subunit (LSU) genes of rDNA were amplified and sequenced using single-cell PCR. Also, they were photographed. A phylogenetic analysis was performed on MrBayes from the combined 18 s -28 s data set. The presence of 15 phylogenetic entities was confirmed, four of which constituted new records for the Mexican Pacific, as well as three harmful species, one toxic and two bloom-forming. Our molecular results evidenced the need to re-evaluate the current taxonomic system of athecate dinoflagellates at all hierarchical levels, integrating them with morphological evidence without preponderance of this criterion over taxonomic decisions.
