What concepts does biodiversity reflect?
Species richness: the number of different species that are represented in a given an ecological community, landscape or region
Species abundance: the relative representation of a species in a particular ecological community, landscape or region
What is a species?
Groups of populations that resemble each other relatively closely and other groups of populations less closely are called species
What are fertile hybrids?

What is hybrid vigour?
