Furthermore, she points out that as a result of this, species that do not need much light will invade their natural habitat.
Q: Is phrase " as a result of this, species subject of "will invade their natural habitat" ?
I've punctuated your sentence correctly and now it makes sense:
The preposition phrase "as a result of this" is an adjunct of reason. It gives the reason that species that do not need much light will invade their natural habitat.
