The first paper from my PhD is now out in @aslo.org Limnology and Oceanography Letters! We used nine years of daily temp and chl data from Peter, Paul, and Tuesday Lakes to show that aquatic heatwaves increased surface chlorophyll concentrations during 24 out of 29 events.

BEHOLD the GARgantuan Alligator Gar!!!
This is the largest Alligator Gar I’ve encountered; at over 7 feet 10 inches (240 cm) and approximately 55 inches in girth, its weight is estimated at 300 pounds (136 kg)!
A true river monster, among the largest caught, tagged and safely released! #GarWeek

Scientists look for cause of spike in swimmer’s itch plaguing Minnesota lakes
The itchy red rash is caused by tiny parasites in the water that can burrow into human skin. Researchers are looking at whether certain waterfowl, invasive species or warming lakes could be factors.

"We conducted extensive monitoring prior to the removal of invasive rats and they weren't detected at all. We believe a small population held on all those years and then, without invasive predators, it finally had the opportunity to recover & grow its population."
