In June of last year, researchers got the first report that sea stars in Washington’s Olympic National Park were succumbing to a new disease outbreak. View Article Google Scholar 13. We hypothesized that asteroid wasting is a sequela of microbial organic matter remineralization near respiratory surfaces which leads to boundary layer oxygen … Sea stars with wasting disease develop lesions in the dermis that increase in depth and diameter, dissolving tissue from the outside in [16,22]. Although delayed compared to areas to the north and south, SSWD was initially most intense in north and central Oregon and spread southward. By August, stars were falling off the rocks—dead by the thousands—at Vancouver Island. Recently however, a severe disease outbreak occurred in a group of very well-studied organisms–sea stars along the west coast of North America. Effects of temperature, season and locality on wasting disease in the keystone predatory sea star Pisaster ochraceus. Google Scholar 35. Dis Aquat Org. Sea Star Wasting Syndrome (SSWS) is one of the largest marine wildlife die-offs ever recorded, killing millions of sea stars from more than 20 Asteroid species from Alaska to Mexico from 2013 to 2015 from yet undetermined cause(s). 1999;5:390–3. Bates AE, Hilton BJ, Harley CD. We analyzed nearly two decades of data from a coordinated … Sea star disease and population declines at the Channel Islands. Sea stars used in this study were photographed for taxonomic verification. Disease outbreaks can have substantial impacts on wild populations, but the often patchy or anecdotal evidence of these impacts impedes our ability to understand outbreak dynamics. pmid:20066959 . View Article PubMed/NCBI Google Scholar 36. Sea star wasting disease (SSWD) is a condition that has affected asteroids for over 120 years, yet mechanistic understanding of this wasting etiology remains elusive. An ocher sea star with new growth from mid-arm after trauma. The etiology of sea star wasting is unresolved. Effects of temperature, season and locality on wasting disease in the keystone predatory sea star Pisaster ochraceus. Sea star wasting disease describes a condition affecting asteroids that resulted in significant Northeastern Pacific population decline following a mass mortality event in 2013. 2009;86(3):245–251. 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. Coelomic fluid surrounds the sea star's organs, playing critical roles in numerous systemic processes, including nutrient transportation and immune functions. Sea star wasting disease (SSWD) first appeared in Oregon in April 2014, and by June had spread to most of the coast. Bates AE, Hilton BJ, Harley CDG. PNAS S ea star wasting syndrome, a disease that causes the arms of the animals to fall off and practically melt away, has wiped out approximately 81 percent of the ocher sea stars living on the coasts of north central California since 2013. Animals collected from the Salish Sea had no symptoms of Sea Star Wasting Disease. Proc 5th California Island Symp. Dis Aquat Organ. One or all arms then detach from the central disc as the sea star dies ( figure 1 a–e ), often leaving only white piles of ossicles and disconnected limbs. Sea stars in the Puget Sound were collected onboard the R/V Clifford Barnes by dredging from depths between 24 and 50 m (Supplementary Table 1). 2009;86(3):245–51.
