Since its population bottomed out, the federally-endangered Piping Plover in the Great Lakes has made a comeback for the ages.
A population that once measured approximately 17 pairs and rebounded, hitting 76 pairs in 2017. The same year that count was made, the plovers had also returned to Gull Point, a nesting location that hadn’t been used in more than 60 years.
In an effort to understand some of the conditions that have allowed this species to return to its habitat, researchers have directed their attention toward a curious instrument for help.

Thirty years ago, white shark sightings near California’s beaches almost never happened. For Chris Lowe, who was a graduate student at California State University’s Shark Lab at the time, spying a dorsal fin from one of the ocean’s top predators was very rare.
Prior to the mid-90’s, an expansive commercial fishing operation and the loss of marine animals decimated white shark populations. If their food wasn’t being hunted, sharks were getting caught in gill nets. At that point, they would be killed anyways before getting brought to the market to be sold.
Then in 1994, California residents approved propositions that banned gillnets in state waters and enacted protections for the white shark.Read More
Where and how to monitor water quality is always a challenge, particularly in complex aquatic ecosystems. The new REASON Project from a team at Clarkson University is working to demonstrate the utility of using water quality instrumentation in dams on major rivers in the Great Lakes system.
Clarkson University Professor of Biology Michael Twiss spoke with EM about the new approach their team is taking at the Moses-Saunders Power Dam across the St. Lawrence River and the benefits the development of smart infrastructure such as this might offer.
“The upper St. Lawrence River is defined as that which leaves Lake Ontario and is just upstream from the city of Montreal,” explains Dr. Twiss.Read More
