Field work fun sampling Minnesota lakes to evaluate the impact of Chinese mystery snails on food webs! #MAISRC

We have been spending the last month scouting Minnesota lakes to sample for our #MAISRC funded project to investigate the impact of invasive Chinese Mystery Snails on littoral foodwebs. As a native Minnesotan who returned 2 yrs ago, it has been a pleasure to explore just a fraction of our 14k lakes!

Spent a couple of days in the lovely peatlands of northern Minnesota installing and maintaining equipment to measure gas fluxes.

Just out in PNAS - Been thinking about these three graphs for nearly a decade with a great team of smart colleagues. We finally have a story to tell that makes these interesting observations make sense. doi.org/10.1073/pnas...
three graphs show the change in streamwater pH, calcium ions and soluble silica for three watersheds at the Hubbard Brook Experimental Forest from 1963 to 2020.

It was a fun afternoon of sharing the work we do at @umnnrri.bsky.social to visitors for our open house last week. Lots of science and work to be shared! My role was to talk about our awesome eddy covariance towers and peatlands in Minnesota!

Superior National Forest seasonal ponds are drying quickly! We are down to 2/9 of or study sites with water yet. We did however sample some of these lovely Dytiscidae larvae from one pond that will likely be gone tomorrow.

When you're a limnologist you worry about lakes and water quality. NRRI's Chris Filstrup was concerned after the 2021 Greenwood Fire and quickly jumped into research mode, launching a study to find out more. This year, that work is even more important. bit.ly/4dAfRj4 #FireLakes #NRRI #LCCMR #MNENRTF

Wildfires could leave lakes murky for years
Research that began after the 2021 Greenwood Fire seeks to understand how wildfires affect a lake’s water quality, and for how long. It also looks at what that means for mercury accumulation in fish.

Anyone have experience using the Onset HOBO MX Water Level Data loggers? I have used the Hobo U20L-01 for many years, but am interested in the MX series as they can be downloaded via bluetooth in the field. Any experiences for recommending the MX loggers or if you all found any major issues?
