Eastern Spadefoot Toads

than usually destroy the environment they are introduced to. Take the cane toad for example; this is an invasive species problem that is currently occurring in the United States. The cane toad (Rhinella marina), is a species that is native to South America, Central America, Mexico, and southwestern Texas. The cane toad began to become introduced in Florida, Hawaii, and even Louisiana. Originally, they were let out around sugar cane plantations in order to eliminate pests that ate the cane. Eventually they “escaped” and people began to keep them as pets and in their backyards. The cane toad preys on and can sometimes compete with native species due to having similar niches. The cane toad also secretes a toxic chemical from its skin, which is extremely poisonous for common household pets, including dogs, cats and birds (Hardman).

The new population of cane toads has been quickly growing throughout Australia while carrying with it, a parasitic nematode, rhabdias pseudosphaerocepala. Once infected with this lungworm, both adult and metamorph toads can experience stunted growth and reduced stamina. This is a problem that is effecting native species. When predators feast on these toads, they become poisoned. Introduced pests can sometimes be controlled by using native predators or competitors. By conducting experiments and finding possible solutions, researchers may be able to protect these native species.

Male Northern Correboree Frogs move into the breeding sites in summer and call their mates in late January to early March from covered mossy chambers at the edges of Sphagnum Bog pools and other overgrown places. When the females briefly visit the calling males they typically lay 20-30 eggs in a nest.

Overall for this change project, we have learned that the population of frogs has been decreasing all over the world. There are many factors that decrease their population like agriculture, invasive species, and the population of humans. Specifically, in California, only 40% of the historical sites in the Northwest area have Foothill Yellow-Legged Frogs, and this has the highest percentage out of all of California. These frogs are indicators for the environment, meaning they can determine if the area around them has changed dramatically due to their permeable skin. For our service project, we removed invasive plants like the Himalayan Blackberries and dug creek beds for the frogs. From this, we were able to improve the levelness of the area

The article explains that several measures were proposed to reduce the cane toad population, and provides three reasons of support. However, the professor explains that it would not be easy to get rid off the cane toad population and several measures taken, but that were unsuccessful, and refutes each of the author’s reasons.

The cane toads damage is not that serious than the brown recluse spider. Their damage is not

In the past we have tried to contain these Cane Toads by setting up traps in the dry-seson however many blue tongue lizard got caught in them. They also tried to set up fences around areas that only have 1 or 2 freshwater lakes in them so that the babies cannot walk away from the area. This worked but we cannot simply fence up all the water sources in the top half of Australia. But I think we should create a poison on the cane toads. Because the other thing that eats Cane Toads is Cane Toads; therefore if we create a poisson on them we are able to get rid of many toads. The first step in creating this plan would be to make the poission. Secondly we would give the poison in a syringe to every homeowner in Northern Queensland so that they can

The mountain yellow-legged frog is declining due to the introduction of trout, contaminants, increased levels of ultraviolet radiation, and the fungal disease, chytridiomycosis. David Bradford, one of the first witnesses to the decline in the late seventies, noticed the species dropping because of the red-leg disease. Because this is a secondary infection, the frog’s immune system was weakened before the disease became existent. The chytrid fungus was first cited in the Sierra Nevada in 2001, brought here from African clawed frogs, but studies have suggested that the disease has been evident since the mid-‘70s. Nearly three decades later, the mountain yellow-legged frog is still declining. Currently, with a ninety-eight percent decline, there

Many sources say that the initial spread of this invasive species began at the end of the 1800's when bullfrogs were shipped to California to fill hungry loggers appetite for frog legs. The frogs competed with the other native species with the supply of natural resources while also consuming and exploiting the native amphibian species as well. Worldwide Rana catesbeiana has driven over one-hundred native species of frogs to extinction (Save The Frogs! et al. 2013). This is a huge impact on amphibian wildlife worldwide because there are about 4,800 species of frogs. Over the past hundred years the bullfrog has wiped out over 2% of the world's species of frogs. Studies have shown one of the reasons bullfrogs will cripple Arizonian ecosystems and the native amphibian species directly is because a female bullfrog’s physiology

The issue I will be raising is one that might not be familiar to all who reside in California and that is primarily focused around the fragmentation and overall mutilation of areas that keep and protect the species Rana Draytonii, otherwise known as the California Red-legged Frog. One of the reasons I raise this issue, is because most importantly “these frogs were named the official state amphibian of California via AB 2364” (Patrick McGreevy.). An even greater reason to discuss this dilemma is because they are limited in their size around the Southernmost California residences, whereas they had previously occupied approximately “70% of its former habitat” according to environmentalists (Campbell.). My goal is to highlight their ecological value to the state and how the California red-legged frog’s value is more significant than the fragmentation and intrusion taking place. These red-legged frogs are currently listed as endangered, but they are vulnerable to human intrusion by means of erecting buildings, projects for road construction, introduction of a non-native species along with habitat fragmentation in areas near where they might usually reside such as near the south Mendocino County and along southern California with populations extending to the Santa Rosa Plateau (Hammerson, Geoffrey). The California red-legged frog has an intrinsic link to

The Black-Footed Ferret is an endangered species. If you have seen one of these on a trip to the zoo, there is a chance that the little board that tells you what it is said that, “Black-Footed Ferrets are an endangered species. You will learn what they look like, what they eat, and where they live. Black-Footed Ferrets have a special appearance, their diet and habitat is special, and they have some interesting facts.

The cane toad, also known as rhinella marina, got its bad reputation soon after being released into the Australian ecosystem in 1935 with the expectation that it would control the destructive cane beetle population. However, instead of controlling pests, the cane toad became a pest of its own. About 3,000 cane toads were released in the sugarcane plantations of north Queensland in 1935. There are now more than a million cane toads and their still expanding over an area of thousands of square kilometres in northeastern Australia. They are large, amphibians with dry, warty skin, and are native to the southern United States, Central America, and tropical South America. Their numbers are controllable in their normal range, but they have boomed

This slug inhabits damp forested areas and places near rivers or streams at low or middle elevations. They need shelter such as rotting logs, dead plant material, or ferns to survive.

Now if you read the title, you should’ve realized by now that I am a toad, a rather big one. Here’s what happened: One day I was going on a swim with my toadlets in our crystal pond when there was giant THUD. Following it, a giant, hair monster! Luckily, my kids managed to swim away and hide under the leaves in the dirty area, but I stayed and defended our home. The

Frogs, toads, caecilians, and salamanders are the members of the class Amphibian (amphi- meaning “on both sides” and bios- meaning “life”). These members always require water for reproduction. Most Amphibians undergo metamorphosis, which is a usually degenerative pathological change in the structure of a particular body tissue. And, in the case of Amphibians, it is the changing of a tadpole into
