These bears are noticeably important food chain regulators, as they have strong top-down effects on their direct prey and associated species [7]. Jaguars are an apex predator, meaning there is nothing in their habitat that preys on them, they are also keystone species in that they help keep prey populations at a balanced level. The minimum species range of an umbrella species is often the basis for establishing the size of a protected area. Local trees, shrubs, and flowering plants have evolved to only be pollinated by Sephanoides sephanoides, a hummingbird known as the green-backed firecrown.
