Sea star wasting disease, thought to be caused by a virus, is killing sea stars along much of the North American Pacific coast. About the Project; People ; Funding; Links and Publications; Unalaska Day 1. In seven years, an estimated 5.75 billion sunflower stars perished from Mexico to Alaska—a population decline of over 90 percent. While I was in Kachemak Bay, Alaska, this summer I observed what I had hoped I would not find: evidence of sea star wasting syndrome. The research, “Evidence That Microorganisms at the Animal-Water Interface Drive Sea Star Wasting Disease,” was published in the journal Frontiers in Microbiology. From Mexico to Alaska, sea stars withered and died, their bodies dissolving into mush, leaving nothing but goo and spines behind. Sea stars have few predators and are believed to have a lifespan of only a few years. A mysterious wasting disease has been devastating sea star populations around the world for several years. The decline was so precipitous that sunflower stars have now been … Many scientists had thought that Alaskan waters were too cold for the virus, but recent warm ocean temperatures might be a contributing factor. Research Area(s): Coastal Change. Populations of the sunflower sea star suffered dramatic crashes because of a marine wildlife epidemic event, referred to as sea star wasting syndrome, that began in 2013. In 2013, sea stars impacted by a wasting syndrome began dissolving into gelatinous goop. this week i went out at low tide to look at the sea stars, and sure enough, i saw several that were looking poorly, and one that was really bad, from sea star wasting disease. Sunflower stars proved to be an especially vulnerable species. The disease causes … and Washington coasts. UAF researchers say this is the first discovery of multiple sickened stars this far north. I took photos of sea stars at Tutka Bay during an ultra low tide in May 2013 and again in September 2013. A disease referred to as sea star wasting syndrome started to spread like wildfire along the west coast of North America in 2013 and has turned 20 sea star species to goo since. Microbial Ecology of Sea Star Wasting Disease Getting Wasted with old friends and new foes. Photo by Greg Davis/KCTS9 Photo by Greg Davis/KCTS9 The research, “Evidence That Microorganisms at the Animal-Water Interface Drive Sea Star Wasting Disease,” was published Jan. 6 in the journal Frontiers in Microbiology. Back then we’d taken 80 … For more than seven years, a mysterious wasting disease has nearly killed off sea star populations around the world. From Mexico up to Alaska, sea stars were struck down by “sea star wasting disease,” and no one had any idea why it was happening. The study titled “Evidence That Microorganisms at the Animal-Water Interface Drive Sea Star Wasting Disease,” was published in the Frontiers in Microbiology journal on January 6 th, 2021. Since June 2013, Sea Star Wasting Disease cases have been reported from Baja California all the way to southern Alaska. Since 2013, sea stars have been dying in record numbers on the west coast, from Baja California to Alaska. The research, “Evidence That Microorganisms at the Animal-Water Interface Drive Sea Star Wasting Disease,” was published on January 6, 2021, in the journal Frontiers in Microbiology. Similar die-offs occurred in the region in the past, but not at this magnitude, nor in Alaska. One of a few Leptasterias sea stars… Hewson feels that ocean conditions result in the production of exceptional amounts of organic material, which prompts bacteria to thrive. 2016). As some sea star populations make a comeback, scientists may have found cause of ‘wasting disease’ By. The wasting disease that has killed millions of West Coast sea stars has now shown up in Kachemak Bay. Within just three years, millions of sea stars from California to Alaska died from a disease called sea star wasting syndrome (SSWS). An epidemic wasting disease, caused by a virus (Hewson et al. A recent paper suggests that warmer water temperatures in the Pacific Ocean could have increased the spread of the disease and the high rates of sea star death in Washington State (Eisenlord et al. Sea stars with SSWS develop white lesions in the ectoderm quickly followed by decay of tissue surrounding the lesions which leads to fragmentation of the body and death. Healthy, multi-armed sunflower sea stars are renowned predators, but this Howe Sound specimen appears to be dying from sea star wasting disease. Posted on September 13, 2015 by teamaquaticvir. We assessed the impacts of sea star wasting disease in the Salish Sea, a Canadian / United States transboundary marine ecosystem, and world-wide hotspot for temperate asteroid species diversity with a high degree of … 2014) b egan in 2013, affecting sea stars from Alaska to Baja California, Mexico. According to Hewson, ocean conditions lead to the production of unusual amounts of organic material, which he said prompts bacteria to thrive. According to Hewson, ocean conditions lead to the production of unusual amounts of organic material, which he said prompts bacteria to thrive. Sea Star Wasting in Tutka Bay, Alaska. Historically located along the coast from Baja California north to Alaska, the sunflower sea star has been decimated by sea star wasting disease (SSWD), which research suggests is exacerbated by warming oceans tied to climate change. After a looong prop plane ride Elliot and Ian arrived in Dutch Harbor, Alaska, where the team had previously performed work in April 2015. Aaron Bolton, KBBI - Homer - June 5, 2019. Some species of sea stars feed on plankton, while other species prefer dead organisms. Primary Contact(s): kris.holderied@noaa.gov. Near Sitka, Alaska, researcher Melissa Miner finds an ochre star with whitened diseased arms — a symptom of sea star wasting disease. Signs of sea star wasting disease have been popping up on both the East and West Coasts of the United States, as well as reports globally. Now scientists believe that it may be respiratory distress. Some of these species stand at the brink of extinction. The problem surfaced in 2013, when sea star wasting disease (or SSWD) was spotted along the B.C. On the West Coast, sea star wasting has been observed as far north as Southeast Alaska, and as far south as Orange County, California. Sea star wasting disease devastated intertidal sea star populations from Mexico to Alaska between 2013–15, but little detail is known about its impacts to subtidal species. Published on: 05/26/2015. At least 20 species of sea stars from Mexico to Alaska were affected by the disease, but the sunflower star, an aggressive predator with 24 arms, was hit the hardest. As many as 20 sea star species have been affected. For more than seven years, a mysterious wasting disease has nearly killed off sea star populations around the world. The reason for the die-off is a mysterious illness known as Sea Star Wasting Disease (SSWD). The absence of sea stars can enable other organisms that sea stars eat, like mussels, to multiply and drive out other nearshore inhabitants. Some of these species stand … Sea star die-offs have been observed in past decades, but none were at this geographic scale. SSWD is currently affecting more than twenty species of sea stars in nine families. None of the sea stars counted or observed in these locations showed signs of wasting disease.

Biologists estimated 95% of some sea star populations were decimated by SSWS. Over the next two years, as geographically diverse populations continued to crash, scientists coined the term sea star wasting disease (SSWD) to refer to the unexplained forces that were causing the devastation.
