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.

If someone speaks to Jesse Ellis, Assistant Professor of Biology at Coe College and Director of the Wilderness Field Station, they might get interrupted; by a blue-headed vireo.
“Bird songs are a big part of data gathering for research here,” says Ellis. “We use automated recording units (ARUs) to record wilderness sounds, especially sounds made by birds and frogs.”
The Wilderness Field Station is a teaching-oriented facility. “In addition to our annual summer classes, we also conduct bird studies here including bird counts in transects, and researchers from other colleges come here to do multiple lake samplings,” Ellis adds.Read More
For most humans, mayflies seem like a nuisance, hovering over the waterways as we try to enjoy them. However, for anyone hoping to monitor the health of watersheds, mayflies are important aquatic species—and now, a digital version of the mayfly is helping some scientists keep an eye on the water. Research scientist Dr. Scott Ensign , who serves as Assistant Director of the Stroud Water Research Center , spoke to EM about how the digital mayfly technology developed.
“ Shannon Hicks is the engineer who started developing the Mayfly six or seven years ago,” explains Dr. Ensign.Read More
