Keystone mutualists are often pollinators, such as bees. Nutrient VectorsKeystone species can sometimes be nutrient vectors, transferring nutrients from one habitat to another. Keystone species are not defined by being predators. Flagship species can sometimes be symbols of general ideas about conservation, not representatives of specific ecosystems. Considered an apex predator at full-size, the adult American alligator has no natural predators and keeps other animal populations from overwhelming the fragile ecosystem. However, specific issues are often associated with a specific animal. The dams the beavers build help to establish and maintain a biodiverse habitat, which is essential for other animals.

Keystone species are not always the most populous in the ecosystem. The lands once ruled by jaguars are being destroyed by logging, large-scale agriculture, ranchland, and urban areas. The Iber wetlands are a sprawling maze of marshes and lakes, lagoons and bogs and watercourses that command the horizon as far as the eye can see. . The reason why jaguars are a keystone species is due to their diverse diet.

As bees take the nectar from flowers, they collect pollen and spread it from one flower to the next, enhancing the odds of fertilization and greater flower growth. Without its keystone species, the ecosystem would be dramatically different or cease to exist altogether. Ecosystem engineers modify their habitats through their own biology or by physically changing biotic and abiotic factors in the environment. The coral also helps to protect the coastline from wave erosion. Indicator species are almost immediately affected by changes to the ecosystem and can give early warning that a habitat is suffering. Keystone species are important because they help promote biodiversity by controlling species that would otherwise dominate the biological community in which they reside.
