Scientists Alarmed as #Whales Suddenly Going Silent
"When you really break it down, it’s like trying to sing while you're starving."

"Researchers are alarmed after noticing a significant drop in the number of vocalizations from #BlueWhales.
"As National Geographic reports, scientists used specialized underwater hydrophones, meaning the aquatic version of microphones, to record and trace the sounds of marine life, allowing them to analyze the impact human activity is having on various species.
"However, as detailed in a study published in the journal PLOS One, devastating heat waves have triggered worrying changes over the past decade, allowing #ToxicAlgae to bloom and undermine food sources for whales.
" 'It caused the most widespread poisoning of marine mammals ever documented,' coauthor and Monterey Bay Aquarium Research Institute biological oceanographer John Ryan told NatGeo. 'These were hard times for whales.'
"As a result, blue whale vocalizations dropped by almost 40 percent, according to the study, with populations of #krill and #anchovy collapsing.
" 'When you really break it down, it’s like trying to sing while you're starving,' Ryan explained. 'They were spending all their time just trying to find food.' "

States Are Eyeing Bird-Friendly #Wetlands to Help Rid the #GreatLakes of #ToxicAlgae
"The #OneidaNation has restored wetlands that help to improve water quality in Wisconsin’s Green Bay while creating valuable habitat that attracts many birds."
Words by Andy McGlashen
Senior Editor, Audubon Magazine
Published June 17, 2024"In the ongoing effort to bring the problem under control, the region’s leaders are increasingly reaching for a primitive but proven tool for capturing and cleaning water before it enters the lake: wetlands. No one believes that #swamps and marshes alone can starve the algae blooms, but experts say they are an important part of the solution. 'Wetlands are wonderful filtration systems,' says Richard Stumpf, an oceanographer with the National Oceanic and Atmospheric administration who monitors #algae outbreaks. And because wetlands around the Great Lakes offer vital habitat where birds can rest during migration or raise their young, restoring them not only improves water quality but also brightens the outlook for vulnerable avian species.
“'There’s momentum building behind #NatureBasedSolutions,' says Kyle Rorah, regional director of public policy for Ducks Unlimited. 'There’s a huge opportunity to get serious about taking a chunk out of the problem.'"

Six rare #sawfish deaths in 7 days have scientists baffled amid bizarre #Florida fish behavior
“There is no concrete, conclusive proof of what is happening yet and that is still to be determined, which is quite terrifying.” said Gregg Furstenwerth, a lifelong diver in the Florida Keys. “If it continues, it is going to be the end of this #ecosystem as we know it.”

"Most tests for toxins have been negative, but scientists have seen an unusually high number of #algae called gambierdiscus that can produce a wide variety of #neurotoxins that can be harmful to fish and dangerous to humans.
#Gambierdiscus is normally found in tropical and subtropical waters all around the world, but the algae can grow quickly when waters are warmer than usual. The climate crisis has brought record hot temperatures to the waters around southern Florida."
