#RedTide
The red tide phenomenon is as beautiful as it is rare. Join us at the Civic Center branch this Thursday, July 24, at 6PM as we learn about the tiny creatures that make the ocean glow! We'll also create our own red tide by crafting glow in the dark seaside scenes! #chulavistapubliclibrary #steam #stem #stemforkids #sandiego #summer #redtide #plankton

Red, red tide
Goes to my head
Kills all the fish that I
Won't eat so
Red, red tide
It's all over you
Blows through the air, we're done
Shortness of breath I know
Shortness of breath I know

Algal Toxins and Wildlife Health
By National Wildlife Health Center September 30, 2019
"Harmful #AlgalBlooms (#HABs) have the potential to harm fish and wildlife, domestic animals, livestock, and humans through toxin production or ecological disturbances such as oxygen depletion and blockage of sunlight.
"To investigate the effects of algal toxins on wildlife, the USGS National Wildlife Health Center (NWHC) has examined over 300 dead animals collected during freshwater and marine #HAB events since 2000. Varying levels of algal toxins were found in over 100 of these animals. In some cases, the history, clinical signs, and high toxin levels have allowed scientists to attribute mortality to algal toxicosis. Recent events have included Kittlitz’s #murrelets (Brachyramphus brevirostris) in Alaska that died after consuming sand lance (Ammodytes hexapterus) high in #saxitoxin (Shearn-Bochsler et al. 2014), #GreenTreeFrogs (Hyla cinerea) in Texas with suspected #brevetoxicosis in association with a #RedTide event (Buttke et al. 2018), and #LittleBrownBats (Myotis lucifugus carissima) in Utah found dead during a HAB event at a reservoir commonly used for recreation and as a source of municipal #DrinkingWater (Isidoro-Ayza et al. 2019).
"In other cases, algal toxins have been detected in wildlife, but their contribution to mortality remains unclear. Part of the reason these detections have been difficult to interpret is that the toxic dose of many algal toxins in wildlife species is unknown and the microscopic lesions (if any) particularly in birds, have not been well described. To better understand the effects of these toxins the NWHC is conducting laboratory exposure trials to determine the lethal dose of toxin in birds and to examine the repeated exposure of waterfowl to sub-lethal toxin ingestion. In addition to exposure trials, NWHC is undergoing a retrospective review of previous detections of algal toxin from NWHC’s case archives to examine demographic, spatiotemporal, and diagnostic features associated with wildlife exposure to algal toxins."

Great guide from KQED about how to protect yourself and your dog from harmful algae blooms in the Bay, which are becoming increasingly common.
If you spot an algae bloom, reach out to our pollution hotline 1-800-KEEP-Bay or email us: hotline@baykeeper.org

A 'red tide' is currently covering the volcanic rocks at Jeju Island's southern coast. Nice contrast, bad odor.

As we head into the summer--when conditions for red tides & other #harmfulalgaeblooms are ripe--help us put pressure on the Water Board to prevent toxic algae in the Bay!
The Board will be making an important decision on this issue in early July. We need your voice! https://baykeeper.org/act-now-dont-let-algae-blooms-become-our-new-normal/ #HABs #redtide #sfbay #sanfranciscobay #bayarea
I wonder if #Gambierdiscus is the cause? They have been testing for #RedTide, but have they been testing for Gambierdiscus?
Disoriented pelican found on Marco Island may have red tide poisoning, experts say
By CNN
May 23, 2024
A brown #pelican discovered on #MarcoIsland last week is presumed to have red tide poisoning, according to the Conservancy of Southwest Florida.
"'Typically, we first get the notion that red tide is around when birds are sick,' said Dr. Michael Parsons, of the Water School at Florida Gulf Coast University.
"The seabird was spotted disoriented on the beach, according to a release. Despite those symptoms, which are common with the #neurotoxic algae, no red tide has been detected in our area, per the Florida Department of Health in Collier County.
"'We have no signs of red tide around, FWC is aware of this situation and will be monitoring it more closely,' Parsons said."

What’s Killing #Endangered #Sawfish in #Florida?
Off #FloridaKeys fish — jacks, snook — swim in spirals or upside down in shallow waters of #Atlantic and #GulfofMexico. So were #stingrays and the occasional #shark. Then, endangered sawfish started dying. Scientists are racing to figure out why but have not yet figured out what is going on. They have ruled out a few potential causes, including #redtide, toxic #algalbloom that has led to past kills.

@failedLyndonLaRouchite It's a very good question! They are clearly super toxic to all sorts of things that impinge on human society, including in some cases humans themselves. But the chemical ecological question for what these polythers *really* do for the algae, is an open question. My hypothesis is prymnesin helps P. parvum hunt it's other little eukaryotes that it eats. (it is mixotrophic - both photosynthetic & predator). But dinoflagellates (i.e. #redtide in #florida) are not mixotrophic
... the red tide ...

#Dinoflagellate vertical #migration fuels an intense red tide https://www.pnas.org/doi/10.1073/pnas.2304590120
"The idea that vertical swimming gives #dinoflagellates a competitive advantage actually goes back more than half a century, but only now do we have the technology to conclusively prove it in the field"
@NuModular All of this is probably a moot point if fossil fuels has the option to buy drilling space in the Gulf of Mexico, equal to the size of Italy...
