Stacking effects from natural sites

[Lykus Cerebros]

A bit late to the party, but I am enjoying the game again after a while.

Now I was really wondering if the effects of having multiple research sites or natural vistas stack when in reach of one dome?

Like is there an advantage to setting my dome up in range of two reseach sites or should I just go for the more convinient space with only one.

Of course

Thanks

After checking more closely I also noticed the effect when placing the dome. Shoudl have looked more closely.
