A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine. 3. A keystone species is a species that has a very large effect on its environment in relation to its abundance.Translation: a very small number of individuals can cause extreme changes in its environment simply by being there. Its presence impacts many other members of the ecosystem, and if its population dwindles or disappears, there can be far-reaching consequences for the ecosystem. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether."

Become a member and unlock. As they mature these stripes fade and become less obvious. In such a community, the extinction of the tiger shark may cause over-grazing of seagrass by dugongs, which in turn would reduce the amount of nursery habitat for juvenile fish and therefore cause a decline in their numbers.
