Скачать или смотреть Ochre Sea Stars Making a Comeback: Recovery on Oregon Coast After Devastating Wasting Disease

Discover the incredible recovery of ochre sea stars on the Oregon Coast after a massive population crash from wasting disease. New research reveals a 'baby boom' boosting populations, with sea stars returning as key predators in the intertidal zone. Learn about the studies from Oregon State University and Cal Poly, the causes of sea star wasting disease, and what this means for marine ecosystems. Keywords: ochre sea star recovery, wasting disease, Oregon Coast, sea star populations, marine life, intertidal zone, Vibrio pectenicida.
This video explores the encouraging signs of ochre sea star rebound following declines of up to 84% in 2014. Experts Sarah Gravem and Bruce Menge analyzed data over 23 years, showing an 8,000% increase in young sea stars and restored predation on mussels. While body sizes are smaller and populations fluctuate, this resilience offers hope for coastal biodiversity.
Wasting disease, caused by the bacterium Vibrio pectenicida, causes lesions and melting-like symptoms in sea stars. Recent findings link it to environmental factors, highlighting the need for ongoing monitoring. Watch to understand the impact on ecosystems and the potential for full recovery.
