Sprinkling sodium chloride on roads and highways during winter months has long been an effective way to avoid hazardous driving conditions. But ongoing research out of Rensselaer Polytechnic Institute is showing that while road salts are essential for human safety, excessive use of them is profoundly affecting freshwater flora and fauna living near roads and developments. Recently, biology Professor Rick Relyea and his team found that frogs in particular have been evolving faster than normal to cope with saltier water. He joins us on this episode of “The Eagle” to talk more about what that means for local wildlife.

Also on this episode, features editor Sara Tracey talks about the big winners and big surprises in this year’s Times Union Best of the Capital Region contest.
