A review of 20 years of data shows that smallmouth bass caught in Lake Erie and Lake Ontario have gotten heavier since round goby invaded.
The Great Lakes represent an ideal habitat for invasive carp, with a surplus of food from algal blooms and expansive waters.
Similar to round gobies in the Great Lakes, invasive carp in some parts of the U.S. have become the meal of choice for native predators.
Understanding the impacts of carp, many resource departments have instituted carp removal programs to help protect the native ecosystem.
Despite doomsday predictions, Asian carp are expected to integrate into the Lake Erie food web without causing any major disasters.
When thinking of invasive species, most would think immediately of invasive animals, but vegetative invaders are just as common and harmful to ecosystems. Previously productive and healthy lakes have been infected by starry stonewort, an invasive aquatic...
Unfortunately, when the species list expands due to invasive species, native populations can be pushed out as they’re out-competed and fall prey to the intruders.
Sometimes it’s dry in the desert, and sometimes it rains — a lot. The additional water pulsing through streams in such an environment can affect fish in many ways, but can native desert fish populations always handle...
Once a stable home for cutthroat trout, Yellowstone Lake is now threatened by invasive stocks of lake trout. Scientists say that an over-eager angler is likely to blame. The lake trout are harmful to the native cutthroats...
In ecology, “landmarking” is defined as the tendency of insects and animals to congregate in locations that make it easier for them to find mates. The sites that they flock to are typically easy to find and...
Virginia's popular introduced blue catfish fishery is something that both trophy- and food-seeking anglers can get excited about. But the health of the Chesapeake Bay ecosystem might be better off if there weren't quite so many of...
Rainbow smelt are an invasive species to the Great Lakes, but the fish have become important to food webs in the basin as they act as both predators and prey to many creatures living there. In recent...
Fish can’t leave footprints, but that doesn’t mean they don’t leave tracks. Anything living in the water parts ways with some genetic material from time to time. Researchers from the University of Notre Dame have improved upon...
