Interspecific = variation that exsists between different species. E.g. the difference between horses and ducks. ... Different genotypess result in variation in phenotype - the characteristics displayed by an organism.

What are the types of intraspecific variation?

Four different processes can lead to intraspecific variation in social organization: (i) genetic variation between individuals owing to local adaptation (between populations) or evolutionarily stable strategies within populations; (ii) developmental plasticity evolved in long-term (more than one generation) ...

What is intraspecific trait variation?

Intraspecific trait variation can alter the number and strength of a species' interspecific interactions, thereby changing the topology and dynamics of species interaction networks.
