The detrimental effects on human health sometimes observed during blooms of Lingulaulax polyedra have been formerly attributed to the yessotoxin analogs this species produces. In this paper we show that natural concentrations of yessotoxin ...
The ornithine-arginine cycle supported a toxic, metalimnic Planktothrix rubescens bloom [0.03%]
鸟氨酸-精氨酸循环支持有毒的金属水层蓝藻鱼腥藻 blooms

Brittany N Zepernick et al.
Planktothrix rubescens is distinct from other cyanobacterial harmful algal bloom (cHAB) genera: the crimson-red cHAB thrives in the cold, low-light, nutrient-limited metalimnion. Studies have attributed this ecological success to buoyancy r...
Spatial distribution and diversity of mcyA gene-carrying cyanobacteria in planktic and benthic communities of Swiss alpine lakes [0.03%]

Cyanobacteria are notorious for producing harmful toxins, including microcystins, which can severely impact animal and human health. In Swiss alpine lakes, past episodes of cattle deaths have been linked to acute hepatotoxicosis caused by m...
Cyanotoxin production in shallow subtropical lakes is driven by nutrient enrichment and primary producer abundance on the millennial scale [0.03%]
亚热带浅水湖中石莼毒素的产生受营养物质富集和初级生产者丰度的影响——千年的尺度视角

Savvas Paradeisis-Stathis et al.
Increased cyanotoxin concentrations from harmful algal blooms (HABs) in lake systems pose a global challenge to water quality. Although progress has been made in monitoring cyanotoxins in modern environments over recent decades, identifying...
Salinity adaption and toxicity of harmful algal blooms in three bays of Great Salt Lake (USA) [0.03%]
美国大盐湖三个海湾的有害藻华的盐度适应性和毒性研究
W A Wurtsbaugh,Malin Olofsson,Gregory L Boyer et al.
W A Wurtsbaugh et al.
Cyanobacterial blooms can be harmful to animals and humans exposed to their toxins; however, their environmental drivers and boundaries still need to be elucidated. Salinity has been demonstrated to be an important driver of community compo...
Differential responses and adaptive mechanisms of diatoms and dinoflagellates to changes in dissolved organic nitrogen components [0.03%]
硅藻和甲藻对溶解有机氮组分变化的响应及适应机制差异性研究

Haoyu Zhang et al.
Dissolved organic nitrogen (DON) composition critically influences phytoplankton community dynamics, yet the species-specific regulatory mechanisms remain unclear. Combining cultivation experiments and transcriptomics, we reveal distinct gr...
Identification of Gambierdiscus species from La Réunion and evaluation of toxicity and toxin profile [0.03%]

Five different species of Gambierdiscus have been identified in La Réunion (G. belizeanus, G. balechii, G. pacificus, G. silvae and G. ribotype 2) by morphological observations in Scanning Electron Microscopy (SEM) and molecular identifica...
A newly developed Germlings Harvester (GEHA) in combination with metabarcoding analysis detected numerous plankton species, particularly HABs-causing species, from in-situ germination of resting stage cells [0.03%]
一种新型孢子萌发采样器（GEHA）结合 metabarcoding 分析技术，从水体中休眠细胞的原位萌发检测大量浮游植物物种，特别是赤潮藻华生物种
