Effects of triazine herbicide terbutryn on physiological responses and gene expression in Alexandrium catenella

Qikun Xing et al.

Summary: Herbicides that enter the ocean through surface runoff pose a significant pollution threat to coastal areas. Triazine herbicides, as photosynthetic inhibitors, are particularly harmful to marine photosynthetic organisms, such as phytoplankton. Herbicide pollution can also lead to other environmental issues, including algal blooms and toxin production. This study investigates the effects of a common triazine herbicide, terbutryn, on the physiological responses and gene expression of the harmful algal bloom species Alexandrium catenella. The results indicate that terbutryn inhibits photosynthesis and reduces the growth rate of A. catenella, highlighting the potential threat of herbicides to harmful algal blooms.

Cell size as driver and sentinel of phytoplankton community structure and functioning

Helmut Hillebrand et al.

Summary: From a systematic literature review, it was found that there are consistent and significant allometric relationships between cell sizes and the functional performance of phytoplankton species. Additionally, there is a rich literature on how cell sizes change in response to various environmental factors, which helps in understanding the impact of cell size on phytoplankton community dynamics. In conclusion, cell size is a highly predictive trait for phytoplankton metabolism at the cellular scale and serves as a suitable sentinel of phytoplankton responses to changing environments.

An investigation on bloom dynamics of Alexandrium catenella and A. pacificum and toxin accumulation in shellfish along the coast of Qinhuangdao, China

Wen-Jiao Tang et al.

Summary: This year-round investigation reveals the bloom dynamics of toxic Alexandrium species, A. catenella and A. pacificum, in the Bohai Sea. It confirms A. catenella as the causative agent of poisoning episodes and highlights the increase in shellfish toxin content following the bloom of A. catenella.

Quantifying seasonal succession of phytoplankton trait-environment associations in human-altered landscapes

Charlie J. G. Loewen et al.

Summary: Integrating species traits in direct gradient analysis provided insights into community assembly and responses to environmental changes. The study on phytoplankton trait-environment relationships in north-temperate lakes and reservoirs in Alberta, Canada revealed both local- and regional-scale drivers of succession, with evidence of deterministic filtering by traits increasing in mid-summer. The research also highlighted potential anthropogenic cross-scale interactions and associations between biogeographic factors and various morphological, physiological, and behavioral traits.

Global harmful algal bloom status reporting

Gustaaf Hallegraeff et al.

Summary: The special issue presents a diverse picture of harmful algal bloom types and their socio-economic impacts at regional and subregional scale. The intensity and frequency of HAB events vary among regions, with some areas managing to control adverse effects on human health through increased monitoring activities, while risks to human activities and economic activities continue to exist.

Understanding the environmental roles of herbicides on cyanobacteria, cyanotoxins, and cyanoHABs

Fernanda Breda-Alves et al.

Summary: Agrochemicals such as herbicides alter the physical and chemical conditions of aquatic ecosystems, affecting the community structure and dynamics of phytoplankton. The formation of cyanobacterial harmful algal blooms can be facilitated by herbicides at environmentally relevant concentrations, leading to a cascading toxicological effect on non-targeted organisms and the aquatic food chain. Further research is needed to fully understand the impact of herbicides on cyanobacteria and phytoplankton communities.

Dynamics of microcystins and saxitoxin in the Indian River Lagoon, Florida

Abdiel E. Laureano-Rosario et al.

Summary: The study assessed the dynamics of microcystins and saxitoxin in six segments of the Indian River Lagoon, finding dissolved nutrients to be the most highly related parameters. The results highlight the synergistic roles environmental and biological parameters play in influencing the dynamics of toxin production by harmful algae in the lagoon.

Low Temperature and Cold Stress Significantly Increase Saxitoxins (STXs) and Expression of STX Biosynthesis Genes sxtA4 and sxtG in the Dinoflagellate Alexandrium catenella

Hansol Kim et al.

Summary: The study evaluated the effects of temperature on cellular STXs and the expression of two core STX biosynthesis genes in toxic dinoflagellate A. catenella. Results showed that temperature significantly impacted the growth and STX production in A. catenella, as well as gene expression levels. This suggests that temperature may play a role in regulating toxicity and STX biosynthesis in dinoflagellates.
