Question? Were salamander eggs taken from the road side sites and transferred to the "wild sites"? The article didn't address if moving stress alone wound cause egg death or a lower success of the wild type eggs that were moved to road sites.

Yes, the salamander eggs were transplanted in both directions -- from the "wild" ponds to the roadside ponds and vice versa.
"The stress of moving was equivalent for both types of populations and did not appear to influence the outcome," said Steven Brady, author of the paper. "This is further evidenced by the observation that two types of populations (represented by the very same families as those employed in the field transplant) performed equivalently well in neutral lab conditions. So basically, the methods themselves did not appear to bias the outcome in any way."
I hope that answers your question.
