The significance of studying the role of keystone species is rooted in their profound impact on ecosystem structure and function. Keystone species, such as sea otters and wolves, have a disproportionately large effect on their environment relative to their abundance. They can regulate populations of other species, maintain biodiversity, and promote ecosystem stability. Understanding how these species interact with others and their habitat assists in conservation efforts and informs management strategies. The removal of a keystone species may lead to dramatic shifts in community dynamics and ecosystem health.
