Non-native feral hogs are becoming problematic in Tennessee. Feral hogs are omnivores thatfeed on native plants, crops, and small animals. They can damage an ecosystem by rootingthrough the soil to look for food and trampling small plants.
Which types of native organisms do feral hogs most likely compete with for food sources?

Invasive Mussels Spreading into Area Lakes
By Morgan Simmons of the Knoxville News SentinelThe zebra mussel is an invasive species that was discovered in the Great Lakes in 1988. Biologists believe these small mollusks, adult zebra mussels average about one-inch long, hitchhiked to North America in the ballast water of large ocean going ships from Europe. From the Great Lakes they spread rapidly throughout the Mississippi River drainage, eventually reaching East Tennessee around 1994.Dispersed by barge traffic and recreational boaters, they've made their way up the Tennessee River system, attaching by the thousands to man-made structures and even anchoring themselves to native mussels.In an interview Tennessee Wildlife Resource Agency biologist Bart Carter said, "As an agency, our best, and sometimes only, defense is educating the public on how to prevent these things from spreading around. A lot of states are taking drastic measures like checkpoints, and inspecting boats near certain water bodies."Zebra mussel larvae are microscopic in size, and can be transported in live wells or any part of a boat that carries water. As juveniles and adults, they can survive several days out of water if weather conditions are moist and humid.They feed by filtering plankton out of the water. Despite their diminutive small size, each adult zebra mussel can siphon a liter of water per day. On Norris Lake, where the water is clear and relatively infertile, the fear is that zebra mussels are competing for the same food that supports larval and juvenile fish and native mussels.Diving ducks eat zebra mussels, and so do freshwater fish such as drums, but they have no food value for humans.Wildlife officials say stopping the spread of zebra mussels is mostly a matter of boat operators cleaning, draining and drying their vessels before traveling from one lake to another. Steps include draining live wells, pulling boat plugs, flushing the engine with clean water, and most of all, drying the boat and equipment for five days before launching into another body of water.
