Some examples of keystone species, and why they are considered keystone species Let us start by a pretty common example, such as the grey wolf (Canis lupus). This is an apex predator that feed on large herbivores such as moose, deer and roe deer, and are in many parts of the world important to keep these herbivore populations from growing too high.
Rain and grass are biotic; wind and humidity are abiotic. Algae and fungi are biotic; temperature and rainfall are abiotic. Oxygen and sunlight are biotic; maple trees and spiders are abiotic. Fish and whales are biotic; plankton and bacteria are abiotic. 2. Why is it useful for an ecologist to identify the keystone species in an ecosystem? The keystone species is only important in early stages of succession, and so the ecologist can. safely ignore changes in its population at later stages.
