When the soybean cyst nematode is a J2 it may then enter the root of the plant, usually just behind the root tip. [9] Once the SCNs have gained entry into the root, they can create specialized feeding cells called syncytia by penetrating the pericycle, endodermis, or cortex cell with their stylet in order to take in nutrients from the plant.

Invasive earthworms have caused a decrease in diversity, seedling populations, forest floor organic matter volume, and overall habitat quality. In addition, there is often an increase in invasive species and a decreased diversity of non-plant organisms. Some species that provide important biological niches to the ecosystem may be eradicated.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...

Like most invasive plants, once garlic mustard is introduced into a new location, it persists and spreads into undisturbed plant communities. In many areas of its introduction in Eastern North America, it has become the dominant under-story species in woodland and flood plain environments, where eradication is difficult. [9]
Most recently, in 2006 researchers from Iowa State University and the University of North Carolina recognised and described a third species, Arundinaria appalachiana Triplett, Weakley & L.G. Clark. The plants that form this species were previously thought to form part of the natural genetic diversity of Arundinaria gigantea (Walt.)
