How Do Animals Use Camouflage in Nature
Camouflage is a type of coloration or pattern that helps an animal blend in with its surroundings. It is common among invertebrates, including some species of octopus and squid, along with a variety of other animals. Camouflage is often used by prey as a way to disguise themselves from predators. It is also used by predators to conceal themselves as they stalk their prey. There are several different types of camouflage, including concealing coloration, disruptive coloration, disguise, and mimicry. Concealing Coloration DanielBehmPhotography.Com/Getty Imagesà Concealing coloration allows an animal to blend into its environment, hiding it from predators. Some animals have fixed camouflage, such as snowy owls and polar bears, whose white coloration helps them blend in with the Arctic snow. Other animals can change theirà camouflage at will based on where they are.à For example, marine creatures such as flatfish and stonefish can alter their coloration to blend in with surrounding sand and rock formations. This type of camouflage, known as background matching, allows them to lie on the bottom of the seabed without being spotted. It is a highly useful adaptation. Some other animals have a type of seasonal camouflage. This includes the snowshoe hare, whose fur turns white in winter to match the surrounding snow. During summer, the animals fur turns brown to match the surrounding foliage. Disruptive Coloration Vicki Jauron, Babylon and Beyond Photography/Getty Images Disruptive coloration includes spots, stripes, and other patterns that break up the outline of an animals shape and sometimes conceal particular body parts. The stripes of a zebras coat, for example, create a disruptive pattern that is confusing to flies, whose compound eyes have trouble processing the pattern. Disruptive coloration is also seen in spotted leopards, striped fish, and black-and-white skunks. Some animals have a particular type of camouflage called a disruptive eye mask. This is a band of color found on the bodies of birds, fish, and other creatures that conceals the eye, which is usually easy to spot because of its distinctive shape. The mask makes the eye nearly invisible, allowing theà animal to better avoid being seen by predators. Disguise somnuk krobkum/Getty Imagesà Disguise is a type of camouflage where an animal takes on the appearance of something else in its environment. Some insects, for example, disguise themselves as leaves by changing their shading. There is even a whole family of insects, known as leaf insects or walking leaves, which are famous for this type of camouflage. Other creatures also disguise themselves, like the walking stick or stick-bug, which resembles a twig. Mimicry The Viceroy butterfly mimics the poisonous Monarch. Marcia Straub/Getty Imagesà Mimicry is a way for animals to make themselves look like related animals that are more dangerous or otherwise less appealing to predators. This type of camouflage is seen in snakes, butterflies, and moths. For example, the scarlet kingsnake, a type of harmless snake found in the eastern United States, hasà evolved to look like the coral snake, which is highly poisonous. Butterflies mimic other speciesà that are poisonous to predators. In both cases, the animals deceptive coloration helps ward off other creatures that might be looking for a meal.

Health Care Setting Communication And Teamwork - 1172 Words
In the health care setting communication and teamwork is paramount. They are both essential in providing high quality of care to patients. Health care professionals will have unique roles that ultimately piece together to reach a common goal and that is to provide a safe environment to satisfy their duties as practitioners to achieve a high standard of care and positive outcomes for patients. Interdisciplinary communication and teamwork among distinct medical workers is an integral part of professional development as it provides insight into oneââ¬â¢s own role as well as the role of others involved in providing necessary care for patients.

Upon ente ring the patientââ¬â¢s environment, initial contact was made to confirm patient details and obtain consent for the examination. The patientââ¬â¢s state of consciousness did not permit the development of rapport. In this situation a prompt examination was required and patient care was critical, it could not be overlooked (Egestad 2008). The radiographerââ¬â¢s role was to adapt to the patientââ¬â¢s presentation and ensure patient comfort with minimal level of involvement from them. This allowed achievement of a diagnostic image and uncompromising care. In this acute setting and with the presentation of this chronic illness, efficiency is key. This allowed the emergency team to follow up immediately by assessing the chest x-ray and adapt their roles and continue their ongoing care (Egestad 2008).

Romanticism â⬠Samual Taylor Coleridge Joseph Turner Free Essays
In a reaction to the rational, conformist conventions of the Augustans, writers and artists of the Romantic era advocated the transcendence of rationality through a sublime and imaginative connection with the natural world. This emancipation from traditional social and moral restraints informed their literary, artistic and philosophical pursuits. It was these qualities that marked the movement as unique in the history of European intellectual discourse. We will write a custom essay sample on Romanticism ââ¬â Samual Taylor Coleridge Joseph Turner or any similar topic only for you Order Now Romanticism derived largely from the ââ¬Ëtranscendental idealismââ¬â¢ of Emmanuel Kant, which proposed that things exist outside the intellect that we simply cannot comprehend through pure reason. Three Romantic texts ââ¬â Samual Taylor Coleridgeââ¬â¢s poems ââ¬ËThis Lime Tree Bower My Prisonââ¬â¢ and ââ¬ËKubla Khanââ¬â¢ and Joseph Turnerââ¬â¢s painting Snowstorm: steamboat off a harbourââ¬â¢s mouth ââ¬â reveal how the human imaginative appreciation of the natural world is able to transcend physical limitations as well as the restrictions of technology and logic. Coleridge, in particular, was a true proponent of the Romantic tradition. He described the uniting of reason and feeling as ââ¬Ëintellectual intuitionââ¬â¢ and saw imagination as ââ¬Ëthe ultimate synthesising faculty, enabling humans to reconcile differences and opposites in a world of appearances. His poem ââ¬ËThis Lime-Tree Bower My Prisonââ¬â¢ clearly exemplifies the power of the imagination, combined with the redeeming and regenerative power of nature, which enables him to overcome the isolation of egotism. The intimate, personal nature of this conversation poem engages the reader as they are transported with the poet to new locations and perhaps themselves transformed. Coleridge presents an idealised view of pastoral England with vividness, intensity and delicacy, thereby stimulating the senses and the mind. Colours used to evoke mood and imagery, ââ¬Ëblue betwixt two Isles Of purple shadow! ââ¬Ë is integral throughout. His vision is visceral, bringing enlightenment and contentment to the poet and the reader. The poet also controls light intensity to great effect; binary opposites reflect his thought process, as in ââ¬Å"pale beneath the blazeâ⬠. He contrasts dark and light, pale and radiant, shadow and sunshine throughout. His thoughts also move from the finite ââ¬Ëdell, overwooded, narrow deepââ¬â¢ of the first stanza to the infinite ââ¬Ëwide, wide heavenââ¬â¢ of the following stanzas. Antithetical concepts of freedom with restriction, absence with presence and the imagined with the real create a systolic and diastolic rhythm that merges Coleridgeââ¬â¢s psychological beliefs with his imaginative experience, aligning with what Kant describes as the individualââ¬â¢s ââ¬Ësubjective realityââ¬â¢. The structure of the poem is cyclic, with emphasis on pain before pleasure, with ââ¬Ëwell, they are gone, and here I must remainââ¬â¢ before the later stanza that begins with ââ¬ËA delight comes sudden in my heart, and I am glad as myself were there. The poet ceases feeling isolated and communes with nature, imagining that he is with his friends, before ending by referring to the lime-tree bower beneath which he sits, and to his friend, the ââ¬Ëgentle-hearted Charlesââ¬â¢, once again. The illumination of natureââ¬â¢s power and its ability to transform can also be seen in another of Coleridgeââ¬â¢s poems ââ¬ËKubla Khanââ¬â¢. The first stan za, set inside the walls of Kubla Khanââ¬â¢s ââ¬Ëpleasure domeââ¬â¢ in Xanadu, contrasts with the second stanza which takes the reader outside those confines, reflecting the same systolic and diastolic thoughts that are evident in ââ¬ËThis Lime-Tree Bower My Prisonââ¬â¢. As Xanadu is a synonym for ââ¬Ëparadiseââ¬â¢ or ââ¬Ëutopiaââ¬â¢, the poem can be considered a reflection on Coleridgeââ¬â¢s perception of heaven, linking to the pantheistic belief that God is found in nature. ââ¬ËThe sacred river Alphââ¬â¢ running through this paradise represents in the realm of a poetââ¬â¢s imagination a holy and divine place. The ââ¬Ëcaverns measureless to manââ¬â¢ reflect the endless creations that can emanate from such a powerful imagination. The ââ¬Ëwalls and towersââ¬â¢ that encircle the fertile ground and the ââ¬Ëenfoldingââ¬â¢ of greenery speak of the poetââ¬â¢s energy in trying to capture and hold onto natureââ¬â¢s power and beauty. The intensity of the world outside the tamed garden highlights the power of the natural world in contrast to the ultimate fragility of man-made structures. The ââ¬Ëdome of pleasureââ¬â¢ built by Kubla Khan may be taken to represent the man-made and may perhaps be a comment, on a wider scale, to the Industrial Revolution. Coleridge juxtaposes this with an image of the natural flow of the river to sea, showing his greater appreciation for the creative force of nature. Joseph Turnerââ¬â¢s painting Snowstorm; steamboat off a harbourââ¬â¢s mouth making signals in shallow water, and going by the lead also contrasts the natural world and the man made. Like the eruption of the natural world in Kubla Khan, this painting illustrates an extreme phenomenon of nature ââ¬â a snowstorm at sea. The Neo-Classicists believed that technology would triumph over nature. Turnerââ¬â¢s painting, however, depicts the awesome power of nature, and its sublime beauty, as it overpowers technology. The steamboat, representing the latest technology of the time, is a symbol for the Industrial Revolution, which was in full swing by this point. The experience of being caught in a storm on board the steamboat, provided Turner with the conception for his painting. Turner claimed that he had the shipââ¬â¢s sailors strap him to the mast, so as to capture the true atmospheric conditions of the event. ââ¬ËI wished to show what such a scene was likeââ¬â¢ Turner wrote. ââ¬ËI got the sailors to lash me to the mast to observe it [the storm]; I was lashed for hoursâ⬠The sleet, the bitterly cold, roaring winds and the surging waves throwing up sea spray were the atmospheric conditions Turner needed to feel. This personal experience of such a sublime moment in nature enabled him to record, through his painting, the feelings and emotions of an individualââ¬â¢s experience of the storm. While Turnerââ¬â¢s original idea for the painting emanated from actual experience, its execution derives from complex imaginative truths. The painting has a very clear relief like surface and the texture is picturesque, as the brush strokes are very evident. Turner wanted to be innovative and to challenge tradition, to produce works that depict a sublime atmosphere and spirit. The painting is an emancipatory expression through its intensity of hue, which renders the image of the boat barely recognisable, thus challenging Neo-Classical mechanistic properties of sharp colours and realism. All three texts ââ¬â the Turner painting and the two Coleridge poems ââ¬â depict the sublime beauty of nature and its ability to transform a negative human mind-frame and to transcend the man-made products of the Industrial Revolution. While the ways in which each of the individual texts show this differs, they each allow the responder to appreciate the same ideas. Coleridge provides two different perspectives in his poems ââ¬ËThis Lime-Tree Bower My Prisonââ¬â¢ and ââ¬ËKubla Khanââ¬â¢. The first is an entirely first-person perspective, typical of his conversational poems, enabling the reader to become involved on a personal level. ââ¬ËKubla Khanââ¬â¢ is mainly narrated from a third-person perspective, giving it a grander story-like feel. Like ââ¬Å"This Lime-Tree Bower My Prisonâ⬠Joseph Turnerââ¬â¢s ââ¬Å"Snowstorm: steamboat off a harbourââ¬â¢s mouthâ⬠represents a personal appreciation of an extreme natural event. The event is shown to be as violent as it is beautiful and the form enables the viewer to visually appreciate it and connect with it on a transcendental level. It clearly illustrates the power of the natural over the unnatural. As Northrop Frye has argued, ââ¬ËRomanticism has brought into modern consciousness the feeling that society can develop or progress only by individualising itself, by being sufficiently tolerant and flexible to allow an individual to find his own identity within it, even though in doing so he comes to repudiate most of the conventional values of society. ââ¬â¢ How to cite Romanticism ââ¬â Samual Taylor Coleridge Joseph Turner, Papers
