Recruitment, an indicator of population recovery, has been spatially patchy and varied within and among regions of the coast. The study used nearly 50,000 surveys from long-term ecological monitoring efforts to quantify regional differences in how sea star wasting disease devastated local populations, an important area of research as scientists brace for more frequent and intense marine disease outbreak events as climate change intensifies. These serve as ideal landing zones for the sea stars microscopic larvae, known as settlers and recruits. First noticed in 2013, scientists all along the West coast have been racing to understand the cause: sea star wasting disease. 2023 [1] There are approximately 40 species of sea stars that have been affected by this disease.
