I found this definition in a book: It is a spatial environmental factor gradient and plant community gradient considered together.
I found a different definition too, that said it is the rate of genetic change that occurs in an environment due to the merging of different varieties of a plant species.This doesn't make sense to me. One cannot measure the rate of genetic change.
Which one is right?

Both definitions are right – depending in which context term “ecoline” is used.
