The abundance or lack of the keystone species will determine the abundance or lack of other species as well.</u> It is common to use lions or wolves as examples of keystone species. If they disappear, certain animal populations that are usually hunted by them will prosper indiscriminately. That will drastically change the ecosystem, perhaps even leading it to its collapse.
