本研究通过构建一个包含混合营养模块的三维耦合水动力-生物地球化学模型,首次量化了混合营养摄食对佛罗里达西岸(WFS)寡营养海域有毒甲藻Karenia brevis (K. brevis)藻华的贡献。模型结果表明,混合营养不仅作为额外的营养来源,中度提升了藻华中心的生长率 ...
墨西哥湾频发的赤潮事件由有毒甲藻Karenia brevis引发,但其在自然环境中受微浮游动物摄食压力的量化始终是研究空白。来自未知机构的研究团队开发了靶向28S rRNA基因D1-D2区的新型qPCR检测技术,实现单细胞级灵敏度检测,结合稀释法首次量化了赤潮期K. brevis与 ...
Understanding the dinoflagellates that regularly wreak havoc on marine and nearshore ecosystems in the Gulf of Mexico could help researchers mitigate the damage they cause. A full description of the ...
When Gulf of Mexico algae don't get enough nutrients, they focus their remaining energy on becoming more and more poisonous to ensure their survival, according to a new study by scientists from North ...
On a muggy morning in early August, Gretchen Lovewell wades into waist-deep water at a home near Dona Bay and heads towards a carcass tucked behind a mangrove stand. A familiar, fetid scent is in the ...
FLORIDA, USA — Red tide is persistent along Florida's Gulf Coast, but conditions are beginning to look better than earlier this year. The patchy bloom of the red tide organism, Karenia brevis, was ...
For a human, getting a species named after you is a Really Big Deal. But an entire genus? Wow. Not that it’s a competitive game or anything, but world-renowned Florida scientist Karen Steidinger can ...
The red tide organism, Karenia brevis, was detected in a total of five water samples collected along Florida’s coasts over the past week, though concentrations remain at very low or background levels, ...
SARASOTA — A symposium of the nation’s top experts in harmful algal blooms has created a playbook for addressing deadly algae in Florida. The consensus findings of 75 researchers titled, “State of the ...
Blooms of the harmful algae Karenia brevis occur regularly along the west coast of Florida, where they can add a green, brown, red, or black hue to the water. But scientists have had difficulty using ...
ST. PETERSBURG, Fla. (WFLA) — Researchers at the University of South Florida led a new study that is the first to identify viruses associated with the organism, karenia brevis, that causes red tide.
Red Tide is a harmful alga bloom caused by a naturally occurring alga (a plant-like microorganism) called Karenia brevis or K. brevis. When K. brevis appears in large quantities – typically in the ...
