1. Species
Groups of population s (which are groups of individuals living together that are separated from other such groups) which can potentially interbreed or are actually interbreeding, that can successfully produce viable, fertile offspring (without the help of human technology). [Ernst Mayr, 1969] The species is the most fundamental unit of evolution and is the most specific taxonomic level.

2. Species area curve
The curve on a graph produced when plotting the cumulative number of plant species found in a series of quadrat s against the cumulative number or area of those quadrats; it is used to determine the number of quadrats sufficient to adequately survey the herbaceous understory.

3. Species diversity
The number of living species on Earth.

4. Species packing
The phenomenon in which present-day communities generally contain more species than earlier communities because organisms have evolved more adaptations over time.

5. Species richness
The number of species present in a community .

6. Species selection
A type of natural selection which acts upon species within higher taxonomic groups. Species selection occurs when speciation and extinction rates are affected by whether the species has a particular characteristic, such that the number of species within a higher taxon which have the characteristic might change depending on how beneficial or harmful it is to a species.

7. Species
One or more populations of interbreeding or potentially interbreeding organisms that are reproductively isolated in nature from all other organisms. Populations of individuals capable of interbreeding and producing viable, fertile offspring. The least inclusive taxonomic category commonly used.

8. Species-specific
Applying only to a particular species ; said of effects that vary depending on the species in question.
