what is growth efficiency?

[monkeynut]

What is gross growth efficiency?

and

What is assimilation effieciency?

What is the difference?

[juan]

gross growth would be the efficiency at which a population gains members, though net growth would take into account losses. assimilation efficiency would be the efficiency at which different individuals or smaller populations are merged with the host population. At least this is what i can infer from my knowledge of biomechanicaldiversitydynamic crap.
