What Are The Similarities Between Australia And The Desert Horned Lizards
The thorny devil of Australia and the desert horned lizard of North America are examples of convergent evolution. They are distantly related, but have developed some very similar characteristics which help them to survive and thrive in similar environments. The desert environment presents many challenges to survival: windblown sand which is hard to move on, extremely high surface temperatures, and open areas with little shade, food, or protection from predators. Over much time, evolution through natural selection has given both of these lizards similar characteristics which help them survive in harsh desert conditions. They have developed pointed heads and flattened duck-bill snouts for burrowing and diving into the sand, enlarged scales

    Grandfather Turtle Evolution

    The age and anatomy of Pappochelys has made it clear to Schoch and other researchers that it is a transitional creature, one that bridges the evolutionary gap between its lizard ancestors and its turtle descendants. These creatures are an important contribution to science in the study of evolution according to Schoch. They can reveal how specific features, such as the turtle's carapace, evolved over millions of years.…

    APES Formation Of Deserts

    1. There are high-pressure and low-pressure belts on Earth because of the differences in area that include the location, the mountain ranges, and the coastal areas. It also has to do with the uneven warming of the sun because of the rotation of the earth on its axis. It also has to do with the air that is found around the equator, as it is uneven. This causes for heat to raise which in turn causes low pressure. Then, the air that moves out of these “lows,” toward the poles result in high pressure. High-pressure belts give rise to many of the world’s largest desert. This is because high pressure that is found in the upper atmosphere results in sinking air. Which in turn causes the air to be warm and dry and creates like a blockade that blocks air from below to rise and create clouds which creates rain. The warm air allows for more evaporation to take place, which causes for drier climate. Another factor contributing to this would be that there isn’t any strong winds either or moisture off large bodies of water that would help these desert areas, causing the land to be dry. Most large deserts are found at 30 degrees north and south of the equator.…

    Venomous Lizard

    Lizards belong to the class Reptilian, Scientists have said that reptiles have been on earth for about 200 hundred million years. Lizards are the largest group of reptiles with more than 4300 species around the world. Lizards are found in sub-tropical and tropical regions of the world. Lizards come in different shapes and sizes. Most of the lizards are quite small have four legs and have a fragile tail that can regenerate when part of it is gone. They look similar to salamanders. Lizards are ectoderms meaning they cold blooded, meaning they depend on outside sources like the sun, to raise and maintain their body temperatures. Eating habits for lizards is very different, it depends on the species. Some lizards feed on iguanas which are insects, some eat rodents, and some eat both rodents and insects. Lizards use their teeth to scare predators off as protection. Very few lizards happen to be poisonous and use their venom as a defence. Other species of lizards rely on camouflage such as the chameleon that is able to change its colour according to its surroundings, as a defensive strategy. Females of most lizard species lay eggs and then are usually left to hatch on their own. The most well-known venomous lizards are the Gila monster and he Mexican Beaded Lizard. They are found in Mexico and south west of United States. These lizards are classified in the Family Helodermatidae which has one genus containing only these two species. Both of these lizards have been known as the only venomous lizards for a long time. But more recently discoveries have been made that there are more…

    Stickleback Lab

    The purpose of the research was to formulate a question and develop a hypothesis based on the variations observed between two populations of threespine stickleback, in order to gain a better understanding of natural selection and evolution. Measurements were taken of the number of scutes, ventral length and standard length in Population A. Population B data was provided by instructor. Four null hypotheses were formed on each of the measurements taken, the last hypothesis being no difference between populations. Data was collected from classmates and then compiled together into an excel spreadsheet. Using the spreadsheet, determined confidences intervals and looked for overlapping in the populations. From the confidence interval, it was concluded that there was a significant change between the populations. All of the hypotheses were rejected except for one. Thus proving phenotypic variation and natural selection occurred.…

    The collared lizard is a species found in the Desert Southwest. Male collared lizards show considerable color variation, ranging from brightly colored to a very dull pattern. Your goal is to determine the function, if any, of male color patterns in collared lizards, using the scientific method. Your tentative explanation is that male color plays a role in attracting females for mating purposes. You predict that females will preferentially choose brightly colored males over dull-colored ones. To test this prediction, you observed the interactions of female collared lizards with their male counterparts. You selected males that were the same age and size, and that differed only in their coloration pattern. You placed equal numbers of the two types of male lizards, bright and dull, in aquariums, along with one female lizard per aquarium. Out of 350 aquariums observed, the female chose to mate with the brightly colored male 277 times, and the dull-colored male 70 times. In 3 instances, the females did not mate with either type.…

    How Marsupials Adapt to the Arid Australian Environment

    According to Geiser (2004), Dasyurids are one of the most effective small arid zone mammals due to their effective use of torpor, which is used to adapt to strong variations in food and water availability. As mentioned by Geiser (2004), Dasyurids utilise torpor during the night or early morning and utilise the sun’s warmth to rewarm from torpor, minimising energy expenditure.…

    Cane Toads in Australia

    The cane toad is regarded as one of Australia’s most highly invasive and feral species. Native to central and south America, 3000 were released in 1935, onto sugar cane plantations. This occurred in hopes of devouring cane beetles that caused a lot of damage to the crops. This is one of Australia’s worst mistakes as these toads could not eat the beetles; they survived on the upper stalks of the cane; out of reach. Cane toads have become an issue by being both highly venomous and eating almost anything that fits in their mouths. This means that vulnerable animals that are native, are missing out on food and becoming endangered. Toads can produce up to 35000 eggs in one spawning, thus spreading through Australia at an alarming rate. (See figure 1 for diagram.)…

    Impact and Control of the Brown Tree Snake as an Invasive Species

    The Brown Tree Snake is well-known for the intense ecological impacts it has had on vertebrate life with its postwar arrival on the island of Guam (Rodda, G. H., & Savidge, J. A., 2007). Around the end of World War II, Brown Tree Snakes were mistakably transported from Australia to Guam by Military ships. By the mid-1980s, the snakes had spread across the island of Guam and were continuing to reproduce in excessive numbers. Since the snake’s invasion of Guam, they have caused a major weakening of the island’s native forest bird species, loss of two lizard species, and a decline in numbers of the Mariana fruit bat. For example, the Brown Tree Snake has eliminated 10 of 13 native bird species on Guam and this loss of native birds has permanently altered the island’s environmental and ecological characteristics” (Shwiff, Gebhardt, Kirkpatrick, & Shwiff, 2010, p. 2). Findings have shown that the Brown Tree Snake may even effect prey populations similar to that of lizards. (Campbell III, E. W., Adams, A., Converse, S. J., Fritts, T. H., & Rodda, G. H., 2012).…

    Similarities Between Alphorn And Australian Didjeridoo

    The alphorn is very similar to the Australian didjeridoo. They both share a similar shape and design. Although the sound is a notable difference. The didgeridoo has a harsh, hard deep sound. The alphorn on the other hand, has a more calming, higher instrument. Personally I believe the alphorn has a great resemblance to the trumpet. Most of the higher notes and the lower notes sound incredibly similar to the trumpet. The alphorn was originated in Switzerland and was used in a way to guide and lure cows and other farm animals into their pens. The blowing is considered an art in the evening as an evening prayer. The main use was for farmers and their communication towards the animals. After the year 1800, the production of cheese was higher meaning…

    Texas Horned Lizard Essay

    They often eat Horned Lizards and other reptiles but, there is a documented case of a rattlesnake being killed by a Texas Horned Lizard’s spines while trying to ingest it (Vorhies 1948). Mammalian predators include infamous animals such as the coyote, bobcat, raccoon, and possum. This long list even includes invasive animals such as the feral pig. Like their avian and reptile counterparts these predators usually predate both the animal and their eggs (Hernandez et al 1997). Last but not least the biggest predators these animals face are human. This comes in many different forms such as urbanization, mass agriculture, introducing invasive species, and directly hunting or killing these animals. With their cryptic behavior discussed earlier Texas Horned Lizards are often run over along roadsides while thermo regulating (Moeller et al 2005). Hunting is historically known for causing the demise of several animals, but in today’s laws prevent this. In retrospect the popularity and nostalgia associated with hunting Bobwhite Quail and catching horned toads is what has created such an effort to preserve…
