Ecological species concept.
Relate to the size of one species- population to the other species.
Keystone Species
Pioneer species
Also known as ecological valence, the degree of adaptation of a living organism to changes in its environment. A species trait, ecological amplitude is expressed quantitatively as the range of environmental changes within which a given species is able to carry on its normal vital activities.

the competitive exclusion principle
A species that can survive in a variety of ecological niches.
Biological species concept, phenetic species concept, reproductive competition species concept, evolutionary species concept, and the recognition species concept.
The main difference between the typological species concept and the morphological species concept is that the typological species concept classifies organisms that share characteristics that set them apart from others, whereas the morphological species concept classifies them as the same species if they appear identical.
Charles Elton(1927)
The park implemented an ecological restoration project to protect the native plant and animal species in the area.
The morphological species concept differentiates species by their physical traits, basically. The biological species concept defines a species as generally organisms that breed with others of the same species; rather a genetic isolation concept. The phylogenetic concept is based on evolutionary relationships and is the concept used by cladists.

Keystone Species
It frees up ecological niches for other species.
