Transcript of The Cane Toad Menace

The Cane Toad Menace Photo based on: 'horizon' by pierreyves @ flickr Introduction Benefits Invasive Species within the U.S. An invasive species is an exotic species whose introduction into an ecosystem in which the species is not native causes or is likely to cause environmental or economic harm or harm to human health. According to the Fish and Wildlife Service
there are 50,000 non-native species that
have been introduced in the U.S. Of these
50,000 species, 4,300 are considered to be
invasive. Species you may recognize -----> Wild Boar - (Sus scrofa) PIG BOMB!!!! http://www.foxnews.com/story/0,2933,275524,00.html Brown Tree Snake -
(Boiga irregularis) Country of Origin Cane Toad or Bufo marinus is native to Central and South America
Very successful breeding habits, female lays thousands of eggs
Both tadpoles and adults are toxic to most predators
Omnivorous diet, will eat dead and living animals. Defences and Predators Skin and glands secrete bufotoxin when threatened
Bufotoxin is extremely toxic and is linked to human deaths from consumption
Bufotoxin is also a hallucinogen, which has caused it to be a classified as a schedule 1 narcotic in Australia, alongside Heroin
Has many natural predators in Central and South America: Cat Eyed Snake, Killifish, Ibis, and Catfish Environmental Impact Cane toads have the largest environmental impact in Australia Sources Estes, Richard and Richard Wassersurg (1963).

"Cane Toad (Bufo marinus)". National Invasive Species Information Center. United States Department of Agriculture. June 15, 2009. Retrieved June 17, 2009.
"Poisonous Bufo May Have Toad Hold On Temple Terrace". .tbo.com. 2007-11-02. Retrieved 2010-04-26. Toxicity In April 2005, the biological effects caused by cane toads were listed as a Key Threatening Process under the EPBC Act. Cane Toads are extremely poisonous.
When threatened the Cane Toad will actually secrete toxins from glands located at the back of its head.
If an animal attempts to consume part of the Cane Toad, they will almost certainly die from the highly lethal toxins.
As a result, the existance of the Cane Toad has caused a drastic decline in several of the indigenous species of Australia.
It is this toxicity that makes the Cane Toads especially threatening to small children and pets. The toxic substance exuded by toads actually works on our nervous system and skin. People who are exposed to the poison of the toad also suffer from lymphangitis (inflammation of the lymph vessels) that have a septic origin. In addition, the poison of the toad also results in paralysis against symptoms. The homeopathic medicine bufo is also useful for children who are mentally weak and people who tend to become mentally disoriented or absent-minded much ahead of time and those suffering from symptoms of epilepsy. Such people may experience convulsions or seizures while they are asleep at night. This medicine is also effective in treating injuries to fingers wherein the pain travels in flashes upward to the arms.
Tell the Tale of the man dieing and wine. The Invasion Eat siblings, eggs. An anticancer protein, BMP1 was isolated from the toad's skin. BMP1 possessed anti-proliferative and apoptogenic activities against cancer cells. BMP1 showed low immunogenic properties with minimum toxicity against normal blood cells. The Cane Toad was introduced around the world as a way to curb agricultural pests.
1844: Jamaica (Rat Population)
1900: Puerto Rico (Beetles/Sugar Cane)
1930s: Florida, Phillipenes, Hawaii, Japan, New Guinea, Carribean Islands The Invasion THEY'RE IN AMERICA!

150 Cane Toads were released in Hawaii. After 17 months, their population was over 100,000.
Florida: Accidental Release. The Cane Toad Menace continues to move further inland and threaten native species and pets. Florida Fish & Wildlife recommends "euthanization". (cont.) BufoToxins can be dried out and smoked, takes the frog a month to rejuvenate, been know since the 1970's, euphoria hallucination 20+ mins. Invasiveness Cane Toad populations spread rapidly.
One reason for this is that they have no natural predators and there are no effective methods of control.
They move into new ecosystems and take over or destroy the habitats of native frogs and other animals.
Since they are toxic to all animals, the local ecosystem becomes less diverse and unsuitable for cohabitation. Water and Disease Cane Toads carry diseases that can spread to local frogs, fish, and even humans.
They have been known to carry salmonella, harmful bacteria, and human parasites.
Cane Toads lead to water contamination because of their large numbers and toxicity. This further damages the balance of local ecosystems. http://oceanservice.noaa.gov/news/weeklynews/june10/eatlionfish.html
