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

    The Frilled Lizard, also known as the Chlamydosaurus Kingii, weigh only one to two pounds. Black, brown, tan and yellow are the colors of the filled lizard. They have a long tail and a large expanding frill on the neck. They are reptilian, so their skin is scaly. The habitat ranges from tropical rainforests to woodlands. Their clutch size is 12. Frilled Lizards are omnivores; they love eating insects. Lucky for them, the filled lizard isn’t threatened at all.…

    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…

    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.…

    4. Adaptive Values of Non-shared traits: The adaptations that have developed in the species is the fact that they are similar to a real “pet” dog that you would normally have in your house. The shared traits are the abilities to hunt for their food, and be able to hunt in packs similar to wolves. The non- shared traits are the short fur. Normally the other family species have long, thick fur. The Dingos have really short, thin fur in order to hunt during the day in a desert against the…

    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…

    Animals fight for survival daily, and sometimes their lives depend on their ability to adapt with their surrounding environments. Natural Selection is the process in which individuals have certain traits that allow them to survive and produce more efficiently (Reece et al.456). The animals that inherit these important traits have a higher fitness; therefore, those without the traits have a lower fitness (Reece et al.456). One example of natural selection is the differences between American Alligator and Albino alligator. The American Alligator acquired dark, thick skin due to the swampy, wet marshlands they live in ("American Alligator." Aquatic Community. AC Tropical Fish and Aquarium. Web. 21 Feb 2013.). It has a higher fitness than the Albino Alligator because their pigment not only hides them from predators, but also gives them an upper hand when sneaking up on prey while hunting ("American Alligator." Aquatic Community. AC Tropical Fish and Aquarium. Web. 21 Feb. 2013.). On the other hand, the Albino Alligator has a much lower fitness and is very rare because it does not have the allele that produces the pigment that has dark skin. The white color stands out like a sore thumb in its dark environment ("White alligator is one of the rarest in the world." Telegraph Media Group. 16 Feb 2009: n. page. Web. 21 Feb. 2013.).…

    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).…
