		Biocontrol of Eurasian Watermilfoil ^Votes:0 Biological Control of Eurasian Watermilfoil Eurasian watermilfoil ( Myriophyllum spicatum L.) isan exotic aquatic plant that was introduced to North America betweenthe late 1800's and the early 1940's ( Aikenet al. 1979 , Smithand Barko 1990 ). It grows rapidly and tends to form a densecanopy on the water surface, which often interferes with recreation,inhibits water flow, and impedes navigation ( Graceand Wetzel 1978 , Smithand Barko 1990 ). Therefore, there is much interest in developingsafe, cost-effective control measures for this nuisance species.Currently, herbicides or mechanical harvesting are most oftenused to control watermilfoil infestations. These methods can providerelief from the nuisances caused by milfoil. As is the case withterrestrial weeds, control often mus Read More Go to Site

Many of these new species are of Indo-Pacific origin having reached the Mediterranean Sea through the Suez Canal : these so called "Lessepsian" migrants now contribute significantly to the biodiversity of the Eastern basin. With increasing attention paid to this phenomenon, invaders of other origin-notably from the tropical Atlantic realm- are now more frequently recognized as well, a result of a natural invasion through the Gibraltar straits or of introduction (accidental or intential) by man.

		Invasive Non-Native Plants of Florida ^Votes:0 Invasive Non-Native Plants in Florida University of Florida, IFAS Center for Aquatic and Invasive Plants Aquatic, Wetland and Invasive Plant Information System With Support From The St. Johns River Water Management District Invasive, non-native plants can and do invade Florida's forests and wetlands. They replace native plant species and often form exotic monocultures (where nothing else grows). In many cases, these stands of exotic plants are not useful to the state's wildlife, which has evolved to depend on native plants for food and shelter. Only sometimes are native animals able to adapt to non-native plants. Should exotic plants replace too much of our native plants, those animals that are dependent on native plants will move away or even perish (become extirpated).

Schmitz Daniel Simberloff Biological Invasions: A Growing Threat An army of invasive plant and animal species is overrunning the United States, causing incalcuable economic and ecological costs. To the untrained eye, Everglades National Park and nearby protected areas in Florida appear wild and natural. Yet within such public lands, foreign plant and animal species are rapidly degrading these unique ecosystems. Invasive exotic species destroy ecosystems as surely as chemical pollution or human population growth with associated development. In July 1996, the United Nations Conference on Alien Species identified invasive species as a serious global threat to biological diversity. Then in April 1997, more t Read More Go to Site

Marine Bioinvaders are organisms that have been introduced into a new marine ecosystem, and thrive within their new environment. In their home environments, these organisms live in balance with their predators, and are controlled by diseases and other ecosystem interactions. The invaders often thrive in their new ecosystem, where controls may not exist to keep populations in check.

		Science News Online (9/4/99): A first: Scientists oust a marine invader ^Votes:0 A first: Scientists oust a marine invader By J. Raloff Worms share a shell. (Culver/UCSB) California scientists announce they have evicted from local waters a South African worm that had been devastating area mollusks. If confirmed, it will be "the first successful eradication of a well-established [nonnative] marine pest" anywhere, says project leader Armand M. Kuris of the University of California, Santa Barbara. The spread of nonnative species is a large and growing problem (SN: 2/13/99, p. 103). Most go unnoticed until they are firmly established. Already widely dispersed?and lacking natural predators?they then prove all but impossible to eliminate.
