i. Biological species concept
A biological species is a group of organisms that are capable of interbreeding and producing fertile offspring, and are isolated from other such groups to avoid reproduction.
ii. Ecological species concept
An ecological species is a group of organisms that share the same ecological niche.
iii. Morphological species concept
A morphological species is a group of organisms that share a unique set of structural features.
iv. Phylogenetic species concept
