Don’t pick up these hitchhikers
Aquatic invasive species—which ones to watch for, how to stop them, and why—are the focus of “Stop Aquatic Hitchhikers!” from 2–3 p.m. Tuesday, July 9, at Lakeside Chautauqua on the Marblehead peninsula. It’s part of a summer series of Lake Erie science talks presented by staff from Ohio Sea Grant and Stone Lab. Admission to the talk itself is free but requires paid admission to Lakeside and a pass to park there. Learn more. (Photo: Invasive round gobies, Dave Jude, Michigan Sea Grant, via Flickr.)
How to ID Ohio’s aquatic invasive species
Want some good cold-weather reading? Ohio State’s Ohio Sea Grant program offers a 160-page PDF e-book called Ohio Field Guide to Aquatic Invasive Species, with color photos for identifying aquatic invasive species and tips for preventing their introduction and spread. Featured are fish, plants, algae, mussels, crustaceans and others, including bighead carp, silver carp, didymo (an alga also called “rock snot”), fishhook waterflea, red swamp crayfish and Eurasian watermilfoil, to name just a few.
Ohio Sea Grant Specialist Tory Gabriel and Eugene Braig, CFAES aquatic ecosystems program director, helped produce the guide, whose introduction says, “Identifying and preventing the introduction and spread of aquatic invasive species are the keys to averting long-term ecosystem damage and ensuring the highest probability of effective control.”

‘They take such good care of them’
Speaking of saving salamanders, there’s some good work being done in Ohio. It helps a big, endangered Buckeye State native, the eastern hellbender, and, in its way, the people who are doing the work. Read the story. It quotes Joe Greathouse, among others, who speaks at Ohio State April 9. (Photo: Eastern hellbender by Brian Gratwicke, CC BY 2.0, via Wikimedia Commons.)
Mountains and rivers without fire and/or with it
Breeanne Jackson, Ph.D. student in CFAES’s School of Environment and Natural Resources, presents “Wildfire and Stream-Riparian Food Webs in the American West” at 4 p.m. today, Jan. 23. “Understanding how wildfire influences aquatic-terrestrial linkages … can inform fire management in aquatic-terrestrial ecosystems and potentially refine ecology theory,” says the event’s website. She speaks as part of the school’s spring seminar series. (Photo: Jon Sullivan via Wikimedia Commons.)
