With millions of tons of cargo moving among the Great Lakes each season, it’s easy for certain small passengers to go unnoticed. One of those was the round goby, a small bug-eyed fish from Eurasia that now swarms the shallow waters of Lake Erie. An ongoing study, based at Ohio State University’s Stone Lab on Gibraltar Island, documents how the gobies jockey for a position in the lake’s changing ecosystem.
Now that federal funds have run out, the State of Ohio has halted destroying ash trees infested with the Emerald Ash Borer and has confined efforts to locating infestations and studying the trees’ decline. About a quarter of Ohio counties are under quarantine because of the insect. But some Ohioans are fighting back with insecticides to try to save their trees.
