National Geographic Society is a 501 (c)(3) organization. Reintroducing a keystone species like an apex predator influences the behavior of other animals in the ecosystem. What role do humans play in the extinction of species? The decades-long absence of the jaguar from this environment means that there is an over abundance of prey animals for Mariua and her cubs to sustain themselves on. Without the jaguar, herbivorous prey animals would decimate the plants of their ecosystem. This feeding behavior keeps the savanna a grassland and not a forest or woodland.

Ecologist Robert Paine, who coined the term keystone species in the 1960s, observed the importance of such species in a study of starfish along the rocky Pacific coastline in Washington state. Woodpeckers live in forested areas throughout North America. Even though these vital species differ according to their environment, they all have one aspect in common. They have a very diverse diet of about 87 different species, which contributes to their importance by keeping the numbers of these species in balance. This market is largely driven by opportunistic encounters between people and jaguars, human-jaguar conflict, and cultural practices surrounding jaguar use. WWF prioritizes raising awareness about the importance of recovering jaguars and their habitat for the benefit of nature and people. Describe the potential effects when a keystone species is removed from a community. Bats are found throughout North America, even in densely populated areas. The concept of the keystone species was discovered by Professor Robert Paine from the University of Washington while studying sea stars in their natural environment in Makah Bay, Washington. Should human beings be considered a nonnative (invasive species) or a "keystone species?" Since a keystone species is not a formal designation, scientists may debate which plants or animals in a particular ecosystem deserve the title. Name an endangered species. Sharks, for example, often prey upon old or sick fish, leaving healthier animals to flourish. What does ecosystem unraveling mean for the tiger and its associated biodiversity in Asia?
