A lot of people sort of have a majestic image of the wolf. And this doesn't include the dinosaurs, that fundamentalists claim were also around at that time!
Males are extremely territorial and frequently kill pups. The Australian Sea Lion Management Strategy is currently monitoring the interaction between sea lions and gillnets and through this observation many fishing habits have been adjusted to protect sea lions.

What is an Indicator Species? I think another good example of a keystone species would be the wolf. Spiders are examples of predatory keystone species as they prey on a wide array of insects which have a very high rate of reproduction.
Their indiscriminate hunting method also helps in checking the population of insects which would otherwise cause a strain on the environment. Mutualist keystone species are species who have a mutually beneficial relationship with their respective ecosystems, and would create disastrous effects if absent from the same ecosystem.
This type of relationship is evident and crucial in the pollination and seed dispersal annimals plants.
What Is a Keystone Species?
An example of a mutualist keystone species whose impact is what animal are by human beings are bees. Bees are a key component in kfystone pollination of plants where some plants have no alternative to this effect.
In the recent past, the global population of bees has seen a huge decline caused primarily by the use of pesticides in agriculture and this has seen a decrease in harvest in fruits. For example, the population of deer or rabbits could explode without the presence of a predator. The keystone species cannot support an unlimited number of animals, and the deer soon compete with each other for food and water resources. Their population usually declines without a predator such as a mountain lion.
Without kfystone keystone species, new plants or animals could also come into the habitat and push out the 4 native species. Some species of spedies are keystone species in the Sonoran Desert krystone North America.
Hummingbirds pollinate native cactus. In areas of the Sonoran Desert with few hummingbirds, 5 invasive species such as buffelgrass have taken over the keystone species. The theory that the keystone species of ecosystems can rely on one keystone species was first established in by American zoology professor Robert T.
Paine's research showed that removing one species, the Pisaster ochraceus, or the sea star, had a huge effect on the surrounding ecosystem.
The sea stars are a major predator for mussels, so when the sea stars were gone, mussels took over the area and crowded out other species.
In the end, the area had less 6 biodiversity than it had before the sea stars were removed.
