How do you identify an indicator species?

Indicator species are often determined using an analysis of the relationship between the species occurrence or abundance values from a set of sampled sites and the classification of the same sites into site groups, which may rep- resent habitat types, community types, disturbance states, etc.

Are bees indicator species?

And because amphibians are both predators and prey, many other animals are affected by them.

What might you look for in indicator species?

An indicator species is any living organism that can be used to measure certain environmental conditions. Determining environmental health by indicator species can be achieved by observing and recording factors like population growth, population decrease, and population density.

What does indicator species mean?

indicator species. n. A species whose abundance in a given area is believed to indicate certain environmental or ecological conditions or suitable conditions for a group of other species. A species whose presence, absence, or relative well-being in a given environment is a sign of the overall health of its ecosystem.
