An emerging species called C. auris is also an increasing cause of invasive Candida infections in United States since 2015. An alien species is a species introduced outside its natural past or present distribution; if this species becomes problematic, it is termed an invasive alien species (IAS). Kudzu, which was initially seen as a way to control soil erosion in the U.S. South, proved to be a fast-growing invader that chokes out other plants and even harbors other invaders, such as soybean rust and the kudzu bug. This method of control works because it often removes the invasive species from any particular environment âas soon as possible,â depending on the method of extraction used. Bambaradeniya Table 1.

Biological Controls - This type of control is the purposeful use of an invasive speciesâ enemies (predators, parasites, and pathogens) â in other words other exotic species â to reduce the invasive species populations. Several invasive species have biological characteristics that pose a danger to the safety of park employees and visitors. Once zebra and quagga mussels become established in a water body, they are impossible to fully eradicate. Surrounding native species that have evolved to defend themselves primarily from other native predators can be ill equipped to handle attacks from new, unfamiliar enemies. Many of these invasive plants are escapees from gardens and landscapes where they were originally planted. Invasive quagga mussels deplete plankton populations, a critical food source for a broad range of Great Lakes species, destroying the trophic balance throughout the lakes. USGS research is focused on invasive fish spread and distribution, genetic and population impacts of invasives, hybridization between native and non-native species, and development of frameworks to assist managers in prioritizing populations for conservation and activities to enhance native populations in the context of invasive species.
