The cane toad, also known as the giant toad or marine toad, is n amphibian that is about 15 centimeters long and weighs about three pounds. Cane toads are a yellowish-brown color with dry, warty skin and a spotted belly. * Originally introduced to Australia by Hawaii, the cane toad is now native to South and Central America, Mexico, and extreme southern Texas. This toad was introduced to Australia from Hawii in June of 1935 by the Bureau of Sugar Experiment Stations to help control the cane beetle population. * The cane toad has become a problem in all of its habitats from Central and South America to Northern Australia.…
The most dangerous invasive species is the cane toad. In the article “aliens invade” on page three it mentions how the cane toad eats lots of wildlife. They were released in Queensland, australia in 1935 and now they range well into the millions. Cane toads still expanding range covers thousands of square miles in Australia. The cane toad's venom is also a mix of toxins that affects the heart but rarely deadly.…
Both the reading passage and the listening lecture are discussing methods to eliminate cane toads from their new environments in Australia. The writer asserts that there have been successful method in getting rid of the cane toads from the sugar cane fields of Australia. However, the lecturer disagrees with the writer's opinion by claiming that the three methods were not successful at all. First, the author claims that humans physically capturing and killing the cane toads has been effective.…

Where climate change is severe and the topography is flat, species would typically have to travel greater distances to find suitable conditions, experiencing greater risks of extinction” (Sandom et al 2014). Results have shown that late Quaternary climate change velocity was related with low modern species endemism of mammal’s amphibian and birds signifying that high extinction rates in the past was more prevalent in more climatically unstable regions. In a report done by Stephen Wroe and his team which studied how Climatic changes influenced the extinction of megafauna he documents how they “used mean annual temperature and annual precipitation anomaly and velocity between the past and the present to represent the…
The book Heatstroke: Nature in an Age of Global Warming by Anthony D. Barnosky explains how mother nature and the wildlife is getting affected by global warming. Living patterns all over the world are alternating due to global warming. The author includes vivid descriptions of how the environment or area of a certain region has changed and his own personal research and expeditions. An emphasis is placed on what was the change in the environment. For an example, at Tambopata, they have gathered data and suggested that the heat is causing the water to evaporate from the soil faster.…
Breeding seasons have also been effected by the rising temperatures. As Stephanie Pappas said " Animal shelters in the US have reported increasing numbers of stray cats and kittens attributed to a longer breeding season for the felines. the breeding seasons of the gentoo penguins have also changed because of them not being able to rely on the ice for breeding. Fruit fly's are also being effected.…
The overall temperature of the earth is increasing significantly over the last few years . The global surface temperature is expected to increase by 1.1º C to 6.4ºC over the 21st century. Due to the high average altitude, the temperature changes and raising sea level should have less impact on Mexico than in other countries. However, low altitude areas of Mexico will be significantly affected.…

All organisms derive from one common ancestor; however, the reason why organisms do not all look alike is because of evolution. When it comes to survival of the fittest it is all about who can adapt the quickest and evolve in order to keep the species alive. Two main factors come into play in evolution: abiotic and biotic factors. Organisms are constantly fighting abiotic forces such as weather. Weather or change of weather is one of the biggest reasons for organisms evolving.…
Waratah Anemone The Waratah sea anemone, Actinia tenebrosa is the most obvious anemone on Sydney's rocky shores, easily known by its red color. It is named after the beautiful red Waratah flower that is the emblem of New South Wales. The Waratah Anemone is named after the red Waratah Flower that is a native to New South Wales. It is also known as the Cherry Anemone.…
Blanchard’s Cricket Frog (Acris blanchardi) Introduction As humans, we get the opportunity to share and coexist on this planet with some extraordinarily unique and diverse organisms. Of such organisms, reptiles and amphibians are some of the most adaptable organisms on Earth, residing on every continent except bitter cold Antarctica. Here in Minnesota, There are 22 species of amphibians and 31 species of reptiles, ranging from the fast moving salamanders to the slow and nimble turtles. I got the opportunity to further research the Blanchard’s cricket frog, in hopes of understanding their feeding behavior, reproductive patterns, seasonal movements, and communication interspecifically as well as intraspecifically. Blanchard’s cricket frogs…
Although animals might struggle to live under the two effects above of global warming for now, animal species completely cannot make it through for the rest of their lifetime because animals cannot improve their bodies’ structures to adapt the change in their habitat. For this effect, cold-blooded animals are specific examples; according to the article “Amphibians Don’t Cozy Up to Warmer Climes,” based on the information of researchers at Stony Brook University, warmer environment shortens cold-blooded animals’ duration such as fishes, amphibians, crustaceans, and lizards because the constructions of their bodies are more appropriate for the cold environment (Leonard, page2). While global warming continues to affect animals’ lifespan, everyone can tell extinctions will possibly happen soon for a great number of animal…
Human activity has a great impact on global warming. Events, such as burning fossil fuels, contributes much of the carbon dioxide that is emitted into the atmosphere. Global warming effects caused by human activity affects the earth 's climate in many ways. It is melting the earth 's poles, glaciers and ice sheets which causes sea levels to rise. It is also shifting climates and precipitation patterns and is forcing animals to migrate.…
Global warming and the world General Purpose: To inform Specific Purpose: To inform my audience of global warming and its impact on our planet Central Idea: The growing concern of climate change and the rising sea level due to globe warming has been a big discussion in many parts of the world Introduction I. Attention-getter: How’s the weather outside? Many of us many not this but the earth is growing hotter as the years goes by.…
