Starfish wasting disease first came to the public's attention in 1978, when a large number of starfish died from the disease in the Gulf of California. Proceedings of the National Academy of Sciences of the USA 111(48): 17278-17283. doi: 10.1073/pnas.1416625111, Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, Virus Calculated as Culprit Killing Sea Stars, Nearshore Benthic Systems in the Gulf of Alaska. SeaDoc was among dozens of collaborators that recently published a paper linking a virus to sea star wasting disease. epidemic wasting disease began in 2013, affecting sea stars from Alaska to Baja California, Mexico. The map includes information from Pacific Rocky Intertidal Monitoring surveys as well as information from logs submitted by other researchers, divers, and the general public. They developed skin lesions, which progressed to the sea stars losing their limbs, and finally causing the disintegration of the whole animal. Densovirus associated with sea-star wasting disease and mass mortality. We are constantly updating our website with the latest reports, and will update the map on a … Similar die-offs occurred in the 1970s, 80s, and 90s, but never before at this magnitude and over such a wide geographic area. Sea stars are the dominant predator in rocky intertidal habitats, keeping mussels in check and providing habitat for lots of invertebrates and algae. These sequential photographs of a single individual demonstrate how quickly the disease can progress and the extent of damage that can be done in only three days. Other species are less abundant, so the impact of the syndrome is not as clear. Burge, C. Drew Harvel, C.S. Map of locations along the Pacific Coast with observed sea star wasting disease. Aquatic animal populations face unprecedented threats to their health and survival from climate change, water shortages, habitat alteration, invasive species and environmental contaminants. The … Hewson, I, JB Button, BM Gudenkauf, B Miner, AL Newton, JK Gaydos, J Wynne, CL Groves, G Hendler, M Murray, S Fradkin, M Breitbart, E Fahsbender, KD Lafferty, AM Kilpatrick, CM Miner, P Raimondi, L Lahner, CS Friedman, S Daniels, M Haulena, J marliave, CA Burge, ME Eisenlord, CD Harvell. The deaths all follow the same, grotesque pattern. Then came the sea star epidemic. Under "Long Term Graph Type" select "species counts data" and under "plot type" select "pisaster". “Densovirus associated with sea-star wasting disease and mass mortality” initially suggested  a link between a densovirus (SSaDV) and sea star wasting syndrome (SSWS) but subsequent work revealed that an association between a viral pathogen and SSWS was unlikely in any species other than Pycnopodia helianthoides. Shortly afterwards, other subtidal sea star species in the region began showing signs of wasting. On the West Coast, sea star wasting has been observed as far north as Southeast Alaska, and as far south as Orange County, California. April 2015; March 2015; February 2015; January 2015; December 2014; November 2014; October 2014; September 2014; Meta. Sea stars inhabiting the Northeast Pacific Coast have recently experienced an extensive outbreak of wasting disease, leading to their degradation and disappearance from many coastal areas. Densovirus associated with sea-star wasting disease and mass mortality. The authors of a 2019 paper published in Science Advances document the rapid, widespread decline of sunflower stars and discuss the ecological implications of … The listing, announced yesterday, is supported by new studies that show a 90-percent decline in the overall population of sunflower stars. A healthy sunflower sea star that measures three feet across cruises across the … To date, we have received reports of at least 10 species of sea stars showing signs of infection. doi: 10.1371/journal.pone.0225248. Assessing the direct impact of SSWS on intertidal sea star populations, and the outlook for recovery. The wasting syndrome, which essentially melts away the sea star, is the result of a pathogen that affected many different species but affected the sunflower sea star the most. Twenty species of sea stars, or starfish, have been affected by the wasting disease. Decimation by sea star wasting disease and rapid genetic change in a keystone species, Pisaster ochraceus. The first photograph in the below series of a sea star with wasting syndrome was taking on June 27th, 2014 on Guemes Island, Washington. At the beginning of September 2013, a die-off of starfish was reported off the coast of British Columbia. Click on a pin on the map to see more information. 2015. Eisenlord, C.J. The reason for the die-off is a mysterious illness known as Sea Star Wasting Disease (SSWD). Below are preliminary maps of sea star wasting disease prevalence for Pisaster ochraceus, with sizes greater than 5cm, based on the online-submitted and mail-in intertidal data for May, June, July, and August 2014 (updated 9/2). - "Assessing the Pathogenic Cause of Sea Star Wasting Disease in Asterias Forbesi Along the East Coast of the United States" Documenting the distribution and health of sea stars along the west coast of North America by means of reports submitted by the general public, collaborative monitoring done by citizen science groups, and our own sampling as part of MARINe Long-Term Monitoring.
