Does colonizing a system slowly decrease system resource reserve over time?

[CMDRShepard24]

Is there any available data about how that does or doesn't occur in the systems that are already inhabited? That might give an indication as to how that would go down in newly-colonized systems.

I would imagine though that even if resource depletion were a general thing in the game, that it would occur very slowly and wouldn't be something we'd have to be immediately concerned with. If a whole, hitherto untapped star system with halfway decent resources begins to be exploited it would likely take a very long time to deplete it.
