When Howard Webb set out to monitor turnover in Whitecliff Quarry Lake, his custom-built system of temperature sensors worked perfectly. Until the muskrats showed up.
Webb, a volunteer with the Lakes of Missouri Volunteer Program , devised an inexpensive array to monitor the lake in St. Louis’ Crestwood suburb. His design for looking at the effect of temperature turnover on algae cycling centered on iButtons, small metal loggers that were very reliable, but not waterproof.
That meant Webb had to find an equally inexpensive way to keep them dry. The solution? Small Nalgene water bottles to hold the loggers. Muskrats, however, mistook the bottles - which became covered in algae - for food, tearing into them and flooding the iButtons.
“We thought, ‘Let’s give this a try.Read More
When pigs get out of their pens, they can really tear up a landscape. Five million pigs in 39 states can tear up a lot of landscape.
“They’re one of the top 100 invasive species in the world. Anywhere wild pigs are not natural and they show up, they do a lot of damage to other species,” said Dwayne Etter, a research specialist with Michigan’s Department of Natural Resources and a part of a research team that tested a new feral swine monitoring technique that uses environmental DNA.
Environmental DNA (eDNA) is genetic material organisms lose in the environment. If a pig crosses a creek or defecates in it, a researcher, in theory, should be able to pull that DNA out of the water further downstream.Read More
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.
A buoy that floats off the coast of Presque Isle State Park , near where Gull Point is located.Read More
