Tune in to @kare11.bsky.social tonight 6:00pm CT: MAISRC Scholar Denver Link featured discussing mercury increases in fish species following zebra mussel invasions. You can read more about this research in this recent @univofminnesota.bsky.social Research Brief: twin-cities.umn.edu/news-events/...
twin-cities.umn.edu
Mercury increases in multiple fish species following zebra mussel invasions
New research from the University of Minnesota found that zebra mussel invasions were associated with increased mercury concentrations in several Minnesota fish species.

“We also believe that maybe mystery snails are acting as a host in some small way,” MAISRC Graduate Scholar Amanda Schuermann said. “So we're collecting those to see if they are containing the parasite that causes swimmer's itch.” @mprnews.org z.umn.edu/swimmers-itc...

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.

A Minnesota ‘lake killer’ surfaced 11 years ago. There’s still no long-term fix.
If caught early, starry stonewort is no longer considered a death sentence for lakes. Still, a decade after it was first discovered in Minnesota, it remains a costly problem with no permanent cure.

19. Invasive Species Research and Communication

Invasive species are a leading threat to native species and biodiversity, are an important driver of global ecological and evolutionary change, restructure food webs, and have caused significant economic damage to aquatic ecosystems. This session welcomes presentations reflecting a broad array of aquatic invasive species research in aquatic ecosystems, including ecological, economic, social science, communications, education, and evaluation research. Presentations about efforts to connect invasive species research to lay audiences (community science, education, etc.) are also welcome.

SCHOLARSHIP ALERT!!! Now accepting submissions for the Alligator Gar Technical Committee Scholarship! The cash scholarship is being provided by @alligatorgar-afs.bsky.social a student to help cover cost for attending the 2026 Southern Division @amfisheriessoc.bsky.social meeting in New Orleans🐟
A $500 cash scholarship is being provided by the Alligator Gar Technical Committee to one undergrad or graduate student. This award is intended to help cover cost for registration and travel to the 2026 SDAFS meeting in New Orleans, LA (March 5-8), annual AFS membership dues, registration and other travel-related expenses. 

This $500 scholarship will be awarded directly to the student and not to the student’s educational institution. A winner will be selected based on the quality of a submission containing the following items:

• Cover letter highlighting research interests
• Letter of recommendation
• Professional biography (CV)

This award is not just for those working on Alligator Gar, but also for those who are interested in research on any gar species. The scholarship recipient is expected to attend the 2026 SDAFS Alligator Gar Technical Committee meeting in New Orleans, where they will have the opportunity to meet and present their gar-related work to the committee.

Think $500 isn’t enough? Stretch your dollars farther by volunteering at the SDAFS meeting to get your hotel room and registration fees waived. 

Please contact the Alligator Gar Committee for more details.

Deadline: December 30, 2025

To apply or if you have questions, please contact:
