Why Is The Cane Toads Problematic
Nobody would have expected just how much damage a palm sized toad could have done. Back in 1935, entomologists were trying to come up with a solution to the beetle infestation which caused the depletion of the sugarcane crop. Reginald Mungomery thought he had the solution by bringing in the cane toad, but eighty years later ecologists are still trying to fix the problem he caused. Mungomery's theory worked in Hawaii with the toads eating the beetles. Unfortunately, the cane toads in Australia ignored them and just lived and reproduced at high rates. The cane toads caused catastrophic damage to the environment. Almost all animals that ate the cane toad died; as a result, there was a 95% mortality rate. Worst of all, cane toads move at alarming rates. Originally they moved six miles annually, but today it is anywhere from twenty-five to thirty-five (Guarino [2-4]). Cane toads are a threat to the environment and all wildlife. It is necessary that we keep the population of these toads under control. …show more content…
According to National Geographic, there were only 3,000 cane toads (also known as Bufo marinus) brought into to Queensland, Australia. Now there is an estimated number of over two billion ([2]). With this large number of cane toads, their impact on the environment is much greater than was ever anticipated. Cane toads reproduce extremely fast, and only need a small pool of water. Females can lay up to 35,000 eggs at once, and they usually lay eggs twice a year. Cane toad eggs hatch in about a day and it takes 2 years for them to become full grown adults (Australian Museum [5]). This large number of toads may not have been a problem if it wasn't for one key trait they have, poisonous

    Cuban Treefrog Research Paper

    Introduced by accident in the 1920’s, this invasive species now resides in Southern and Northeast Florida through the means of shipment transportation (Nonnatives - Cuban Treefrog). Its toxic skin and voracious appetite contributes to the Cuban treefrogs’ growing numbers and the native frogs’ decreasing numbers (Nonnatives - Cuban Treefrog). The Cuban treefrog also causes problems for humans directly, as its preferred habitat is cultured, urban locations, such as gardens and citrus groves (The Cuban Treefrog in Florida) . There have been multiple accounts of Cuban treefrogs being found in people’s homes - in their flower pots, yards, and even in their toilets (Cuban Tree Frog: Invasive Species Takes over Resident's Yard). For these reasons efforts have been made by conservation scientists at the University of Florida to warn and inform the general public of the threat Cuban treefrogs pose (The Cuban Treefrog (Osteopilus Septentrionalis) in Florida1). Articles have been placed on the internet explaining how to euthanize the local treefrogs in your yard using easily-accessible supplies (The Cuban Treefrog in Florida). It is through their efforts that they hope to contain the treefrogs’ growing…

    Biological control agents must be extensively studied and trialled in quarantine before being released into the environment to ensure that the insect is specie specific to lantana and will not attack native vegetation. Australia failed to follow this protocol in the 1930s, and introduced cane toads (Rhinella marina) to northern Queensland to protect sugar cane from native beetles. Since then, cane toads have had devastating effects on Australian ecosystems by devastating the predator population. They had no impact on the native beetles at all, and their population continues to grow (National Museum of Australia, n.d,…

    Pacific Tree Frog Research Paper

    Frogs and other amphibians are important for several reasons. One reason is that they are an integral part of the food chain, as they serve as both predator and prey (What Do Frogs). Without them, the ecosystems they live in would suffer. For example, frogs feed on pests, such as mice or insects, which infest human homes and consume crops. Without frogs and toads to feed on them, the populations of such pests would grow rapidly. Many of their prey even spread diseases, like mosquitos which spread malaria, so frogs play a direct role in keeping humans healthy. Tadpoles, juvenile frogs and toads, clean waterways by feeding on algae, which cuts down on costs that would otherwise be needed for water filtration (Why We Must). Additionally, frogs also serve as prey for a variety of organisms, from predatory birds, fish, and snakes, to larger insects, other frogs, humans, and more. If frogs die out, all of their predators would have to cope with a lack of food sources as well (What Do Frogs). Furthermore, because amphibians live in both water and land, they play key roles in transferring nutrients between the two. Without them, all organisms in their environments would suffer. Food webs such as this are simply too interconnected for the loss of one creature not to affect the rest, especially not creatures as vital as amphibians (Amphibian…

    Deformed Frogs in Minnesota

    In the past few years, citizens of Minnesota have discovered deformed frogs scattered throughout the state. There are many speculations as to how the frogs got such deformities. Some scientists believe that its something in the waters of the Minnesota wetlands, other factors could be parasites or ultraviolet radiation. Minnesota is not the only location in the world that has reported deformed animal sightings, but almost three-quarters of the deformed frogs were reported in Minnesota. This is not necessarily because Minnesota contains the most deformed frogs, because scientists are unsure if that is true. Residents of Minnesota are most aware to the problem, so they are basically looking out for the frogs. Deformed frogs are most commonly missing limbs, have extra limbs, or have some bent limbs. Also, there are internal deformities that one would not be able to tell just from looking at the frog. These include digestive and urinary problems, and a slow ability to eat, avoid predators, and move. Because of this most frogs do not survive the winter, and if they do, deformed frogs do not advance on to a second year of living. Deformities do not occur in all frogs, the most common frogs with these malfunctions include the wood frog, American toad, and the northern leopard frog. Since deformed frogs have been found in ponds and both the urban and rural parts of Minnesota, scientists have concluded that well water can produce such malfunctions. Several tests have been preformed on the water that Minnesota residents are drinking and nothing has been found. The Minnesota Pollution Control Agency and the National Institute of Environmental Health Sciences have been performing tests to help solve the problem of deformed frogs in Minnesota.…

    Cane Toad Essay

    There is worry that they will eventually be able to spread to South Australia through the river systems. The government is creating a plan under the EPBC Act to address the impact of cane toads on native species and ecological communities. Also, there is community ground control work and various research projects that have been funded. There is a cane toad advisory group that has been formed which consists of government representatives from the affected state areas. This group monitors the spread of the cane toads and retrieves advice from experts. The affected states have funded research for monitoring the impacts of the toads and trying to find their vulnerabilities. They also have resorted to trapping them and also manually removing them. There are volunteers that work at night to try to catch them in order to stop their further spreading across the country. They put them in containers and then use carbon dioxide to painlessly kill them. The country’s hope is that continuing research will help lead to a better knowledge of the cane toad’s vulnerabilities so that they may be able to find a way create a local containment or eradication of…
