Steve.Lundeberg@oregonstate.edu, Molly Blancett In rocky intertidal habitats, disease rapidly depleted populations of the dominant sea star, Pisaster ochraceus. It also points to sea star recovery as a potential key tool for kelp forest recovery. Shortly afterwards, other subtidal sea star species in the region began showing signs of wasting. Sunflower sea stars may play an important role in maintaining healthy kelp forests, and were once abundant throughout their range in marine waters from Alaska to Baja California, Mexico. Alyssa Gehman,a postdoctoral researcher at the HakaiInstitute and the University of British Columbia (both partner institutions on the study), says thedie-out has put the sunflower sea star onthe critically endangered list one step away from extinction. We analyzed sea star counts, biomass, size distributions, and recruitment from long-term intertidal monitoring sites from San Diego to Alaska to assess regional trends in sea star recovery following the outbreak. Meanwhile, a theory based on environmental stress is brewing. Pseudonyms will no longer be permitted. Slow recovery. The team has conducted these surveys at 12 sites since April 2014, when the outbreak arrived in Oregon, offering a broad and long-term examination of the whole coastline.

Closed Captioning and Described Video is available for many CBC shows offered on CBC Gem. While researchers are still trying to figure out the exact cause of the disease, warming waters have exacerbated it. Sunflower sea stars, listed as Critically Endangered by the International Union for the Conservation of Nature (IUCN), are generally thought to play a role in supporting healthy kelp forests via predation of kelp-eating purple urchins, but this important relationship has never before been quantified. The recent collapse of predatory sunflower sea stars ( Pycnopodia helianthoides ) owing to sea star wasting disease (SSWD) is hypothesized to have contributed to proliferation of sea urchin barrens and losses of kelp forests on the North American west coast. Raimondi doesnt want to leave people thinking everything is doom and gloom. Audience Relations, CBC P.O. 's response to tiny homes resolution elicits disappointment.
