The Power Of The Frog-Counting System

This final affirmation score will be a compilation of your scores from the “Investigation of Animal Behavior” from step 1, the “Survivorship and Population Models” from step 2, “Invading Bull Frog Case Study” and “Population Biology Virtual Lab” both from step 3 and “Biome Project” from step 4 and your completion of this section.

"Maybe you understand frogs and maybe you don't understand ‘em; maybe you've had experience, and maybe you ain't only a amateur, as it were. Anyways, I‘ve got my opinion, and I'll resk forty dollars that he can out jump any frog in Calaveras County. I should judge – he can." (The Notorious Jumping Frog of Calaveras County)

The importance of El Valle De Anton spurred the movement to create systems to preserve frogs worldwide. In Panama a town name El Valle De Anton once deeply respected their golden tree frogs, and ironically they were not disturb when the frogs started disappearing. When the corpses started to pile up, the scientific community began to become concerned and began an effort to preserve the golden frog species and what they found was that frogs from around the world had been plagued by Batrachochytrium dendrobatidis-batrachos (or “Bd” for short). This plague is very hard to stop, as we cannot purge the entire planet of the disease, and the plague spreads incredibly quickly.

TYPHOID MARY IN THE FROGPOND: CAN WE USE NATIVE FROGS TO DISSEMINATE A LUNGWORM BIOCONTROL FOR INVASIVE CAN TOADS?

The Northern Correboree Frog is an endangered species that is restricted to montane, subalpine woodlands, grassland and heathland 1,000 metres above sea level. The estimated amount of Northern Correboree Frogs is 1000-5000. One of the reasons why the Northern Correboree Frog is endangered is because of climate change. Climate change affects the Northern Correboree Frog because it was predicted that its population would decrease in winter and spring precipitation because, this would make one of the popular breeding habitats (edges of bog pools) very saturated and dry, which makes it hard for the frogs to breed.

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 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

Chapter One details the ancestry of frogs and examines the timeline of amphibians on Earth, as well as the increase in frog extinction rate. Kolbert argues that the observed extinction rates which are exceeding expected background extinction rates suggest that catastrophe is ahead for Earth. Humans are key to the extinction of Panamanian frogs due to their spreading of the Chtrid fungus, which is not native to Panama. Thus, Kolbert sees humans

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 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

During my summer on August 23, 2015, my brother and I went to Kensington metro park to see if we could catch a frog. At the park we found a pond full of frogs and we finally caught a frog called The Bull frog, it had green and brown spots and a bright green upper lip and a creamy yellowish belly, it was three to eight inches long. Bull frogs is mostly found statewide, but numbers have been reduced locally due to overharvesting for "frog legs." Now rare over much of state. The Bullfrog could be as the size of a toad, but there is a big difference. Frogs have two bulging eyes

          Through this work and learning about the conservation efforts behind these salamanders have I found my passion. By the end of the day, despite being dripping with water, arms sore from transporting buckets of siphoned water to dispose of, I feel truly at home. So, and while it's still in development, I have been developing a simple behavior experiment to determine how often younger hellbenders surface for air compared to their older counterparts. I am to reveal and discuss my experiment outcomes with a group of biologists sometime in the spring of

Frogger is a retro arcade game of 1981, noted for its novel game play and theme. In the game, the player should direct the frogs to their homes one by one by crossing the roads and navigating them from a river full of threats.

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
