 This study examined the relationship between the seagrass species Sostra and Nolte and its main predator, the migratory goose branta Bernicola. The researchers used satellite imagery and ground based observations to measure the effects of the goose population on the seagrass growth and abundance. They found that the goose population had a positive influence on the seagrass growth, which was reflected in higher seagrass abundances in areas with more geese. Additionally, they discovered that the goose population had a direct impact on the seagrass growth through grazing, which led to increased seagrass production. This study demonstrates how the presence of a predator can have a positive effect on the environment, and suggests that protecting the goose population could be beneficial for the seagrass health.
