Indicator species
An indicator species, also called an ecological indicator, is a sensitive species used as an early warning indicator of environmental changes within a given ecosystem.
An indicator species shows these changes through visible, observable signs in the modification of its physiology, for example, leaves turning yellow, the presence of antibodies, etc.
Bees, hedgehogs or even frogs can be indicator species. © Autan CC by-nc-nd
