A recent study ( Santos et al. 2013) published in the journal
of Environmental Toxicity Chemistry revealed that low concentrations of NaCl
exposure to Pelophylax Perezi), or Perez’s frog embryos lead to a protective
trait on additional effects of copper toxicity. Additionally, it was observed
that exposure to NaCl in tadpoles resulted in a more lethal copper toxicity.
This new and innovative research shows that salinity can have a beneficial
effect on other lethal chemicals exposure during the life stages. This is
extremely important with the ever increasing salinity in the breeding habitats
for amphibians, having resulted from agricultural runoff and other
anthropocentric actions. As we continue to advance our technological innovations
that allow society to continue to flourish, we continually add to the damaging
effects of our actions to the environment. IF unregulated, human actions will
significantly (and have already significantly) effected the reproductive habits
and habitats of amphibians.

You caution that anthropogenic impacts can harm amphibians, but this article seems to show a benefit of sorts. Is increased salinity a good thing for amphibians? What are the implications of finding that these two stressors might counteract each other? Can we generalize this result to other toxins, species or life stages?
Also, what is the title of this article? Where can we find it - is there a link to the source?
