Behavioral Adaptations in Turtles to Thermoregulation and Survival Essays

Behavioral Adaptations in Turtles to Thermoregulation and Survival Essays Behavioral Adaptations in Turtles to Thermoregulation and Survival Paper Behavioral Adaptations in Turtles to Thermoregulation and Survival Paper Thermoregulation is necessary for ectotherms to survive. One important mechanism for thermoregulation seen in turtles is the ability to migrate between land and water habitats. This mechanism was studied using I-button data loggers placed inside marshmallow peeps to record temperatures In two different microhabitats; one In a stream and the other on the bank adjacent to the stream. Five samples were placed in each microhabitat and temperature was recorded every minute for 20 minutes. It was hypothesized that turtles In moving waters, such as streams, would exhibit lower body temperatures than those residing on banks alongside streams due to convection of the moving water. The results of this experiment Indicated a slgnlflcant dfference between body temperatures of the model turtles in each microhabitat. The temperatures of the samples in the stream were significantly lower than those of the samples on the bank. These results indicate that the convection from the moving stream waters provide effective means for lowering body temperature in ectotherms nd, therefore, can be a critical behavioral adaptation for turtles Inhabltlng areas with warmer climates. Introduction Body temperature is a characteristic that is crucial to an organisms survival. It affects numerous biological processes In organisms Including growth, metabolism, reproduction, and performance (Fitzgerald et al. 2006). In endothermic organisms, body temperature Is regulated by metabolism. However, In ectothermic organisms, such as turtles, body temperature Is not maintained by metabolism; instead they must rely on the thermal environment surrounding them to regulate their body emperature. The mechanisms most responsible for body temperature changes In ectotherms include radiation, conduction, convection, and evaporation. Radiation is the gain or loss of heat energy from the sun. This mechanism Involves ectothermic organisms changing their body temperature by changing their position in relation to the sun. Convection is or the gain or loss of heat to or from an organism in moving fluid such as water or the wind. Convection causes the body temperature of the ectotherm to equilibrate towards the temperature of the surrounding air or water. Conduction Is the gain or loss of heat to or from surfaces, and evaporation, or the loss of heat due to the conversion of liquid water on the body to gas (Thermal environments [date unknown]). These mechanisms of thermoregulation can govern the behavior of ectotherms_ In order to regulate their body temperature, ectotherms must either utilize these mechanisms by finding habitats that expose them to these tors protection from these elements. Semi-aquatic common snapping turtles in South Carolina, Chelydra serpentina, use behavioral adaptations such as basking in the sun to raise body temperature or swimming in streams, rivers, lakes, etc. o lower their body temperature (Bennett et al. 2005). In a body of moving water, such as a stream, convection from the movement of the water causes the turtles body temperature to equilibrate to the temperature of the water at a rapid rate. This is beneficial because it allows turtles to quickly lower their body temperature when necessary. It can be a disadvantage for turtles because they may need to use water to find food or escape predators even when the water temperature is lower than their optimal temperature ranges. The rapid heat loss due to the convection of moving water will cause the urtles body temperature to quickly equilibrate toward the lower water temperature which may hinder the performance level of the turtle. Fortunately, according to laboratory studies, reptiles like the turtle are able to heat faster than they cool off so they can raise their body temperatures fairly rapidly by basking in the sunlight (Fitzgerald et al. 06). These behavioral adaptations of turtles that allow them to migrate between microhabitats with different thermal environments quite easily, allow turtles to survive in more diverse climates, escape from certain predators, and orage for food in more locations. This ability to adapt is especially important today when we are facing issues such as global warming and seeing so many species become endangered or even extinct. This experiment was done in order to observe the temperature differences between ectotherms, specifically the Chelydra serpentina turtles, in different microhabitats in order to see how much of an effect changing habitats has on a turtles body temperature. In order to do this, a stream was chosen for the first microhabitat and the bank along the sides of the stream for the second microhabitat. Both microhabitats were located in the shade in attempt to eliminate the effect of radiation on body temperature. It was hypothesis was that the turtles in the stream would have a much lower body temperature than those on the bank due to convection. To model the turtles, I-buttons placed inside of marshmallow peeps were used. Materials and Methods The samples used to model the Chelydra serpentina were I-button data loggers each placed in the center of a marshmallow peep. The use of peeps made it easier to suspend the I-buttons in various locations. In order to keep the I-buttons inside each f the peeps, scissors were used to cut small circles in the center of each peep. These I-buttons record the temperature every minute. These I-buttons were kept on ice in a thermos prior to beginning the experiment in order to create a thermal rise that facilitated locating the start of the experimental data when extracting it from the l- buttons. The habitat used for the experiment was a shaded area containing a stream and the bank surrounding the stream where turtles may inhabit in order to seek refuge from the hot temperatures of South Carolina at noon during the summer. The reek was shallow, about a foot deep, and contained mostly sand with a few larger rocks on the bottom with a steady current. Both areas were completely shaded to eliminate radiation as a factor. A total of ten peeps were used and five were placed in different areas in a stream, while the other five were placed in various areas along the bank of the stream. Strings were tied to the samples placed in the stream and samples submerged and to keep them from being carried away with the current. The samples were left in their locations for twenty minutes in order to give the I-buttons ample time to equilibrate to the environment. This data was then extracted from the I-buttons and organized by temperature per minute for each sample in separate excel tables for each microhabitat. The average, standard deviation, confidence interval, and upper and lower confidence intervals for the temperature each minute was calculated using excel for each of the microhabitats. The temperatures for the last minute, the 20th minute, for each sample were organized into another table separated by microhabitat.

Global Warming - Research Paper Example This paper stresses that the IPCC regards the act and measures made to counter increase in temperature as mitigation and these activities include attempts made to reduce emission of greenhouse gasses and enhancement of the ability of carbon sinks in order to increase the absorption of GHGs that are found in the atmosphere. This report makes a conclusion that IPCC created a report according to which policies need to be made in order to decrease the emission of greenhouse gasses. Another method through which the effects of global warming can be offset is through the method of adaption to changes in the climate. Adaption can be conducted in three ways, it can be planned beforehand as a reaction to changes to the climate that have already occurred or climatic changes that are yet to occur. This method is still in the process of research where its costs and outcomes are yet to be figured out but this method have been adopted on small scale basis. Global warming can be countered at the individual level as well as the organizational and the state level. If individuals, organizations and state conduct certain activities they can counter the challenge of global warming. Opponents of global warming even state that activities conducted by human beings are not the major contributors of increase in emission of carb on dioxide and instead it is the natural events that are resulting in increase in carbon dioxide. They even state that it is natural for the earth to warm and cool over different time periods because of the natural process and if currently the earth is warming.

Issue in Contemporary Management - Essay Example It is difficult for a small organization to effectively manage, control and coordinate between different diverse organizations. Moreover, statutory power given to LOCOG regarding ownership, compensation, and regulation is temporary. In other words, LOCOG has to give up all the infrastructure facilities developed for the London Olympics after the Olympics which will definitely reduce their revenues after the London Olympics. Infrastructure development opportunities are immense as part of conducting London Olympics. Development of infrastructure to world-class level will change the face of London city. LOCOG will receive a share from international Olympics committee’s broadcasting revenue and also from their own marketing efforts. This revenue can be utilized for the economic development and regeneration. Increased employment opportunity is another advantage of conducting Olympics in London. The public will also get an opportunity to know more about different culture which will help to grow the English culture. It is impossible to conduct Olympics without causing some inconvenience to the public. Some of the local businesses needed to be displaced to develop infrastructure for the London Olympics. This displaced business groups may engage in legal battle with LOCOG. Infrastructure development to world class standards is a major challenge. Ensuring value for money and economic benefits to the cost bearing public is another threat to the LOCOG. The public is lavishly extending their support to the Olympics considering a huge return in terms of economic development and infrastructure development. Failure to fulfil the expectations of the public may create problems for LOCOG in future. Stage management and coordination of events are also not an easy task for LOCOG considering its small structure. Propaganda spreading through media is another threat for this event. Many people are spreading the

The Muslim World Essay Example for Free

The Muslim World Essay World is divided into different divisions depending upon the economic conditions, race, culture and most importantly religion. The division of world is more evident after the September 11 attacks into Muslim world and anti-Muslim world. The political ideology and attitudes were now deeply rooted among the individuals also. â€Å"The anti-Muslim attitudes of West united the Muslim world â€Å"is a blanket statement and have strong relevance to the present day. Western attitude: The conflict between in not a new one, it is continuing from 14 centuries some of the conflicts of the history are Ottoman Turkish empire expansion, quasi-colonial regimes by Britain and France, Britain occupation of Iran etc. The first and most important issue is the stand of United States in the ‘Israeli-Palestinian’ Conflict. The need to explain the policies of it on the issue were undermined and unheard. The role of the Western media which is publishing derogatory statements is also a cause of concern. US media used the terms such as Muslim fundamentalist, Shia extremist, Wahhabi zealots, Islamic Jihad, Islamic suicide bomber, Arab killer etc (Ali Khalid, 2008). The Muslim world is victimized more than the situation. Many allegations made by the West on different Muslim countries without any proofs. West failed in providing the evidence of the allegations after the war against the Iraq and its shift in the reasons for war, Muslim prisoners were tortured even after the wars, prolonged occupation etc are also serving as anti-American resentment (Duiker Spielvogel, 2009). Strong factors that united Muslim World: The anti-Muslim attitude united the Muslim world and started to have a common perception as a whole on West. The main reasons for this is unfavorable images where the Muslims are unfairly portrayed in media, Western Military presence in middle east making them U. S long term military base brining insecurity in the region, The containment policy toward Iraq with economic and military sanctions on it, the strong U. S policy towards the Arab-Israeli conflict, Support of the West to unpopular regimes etc. All these factors are allowing the Muslim world to rethink on their status ( Prados, 2001). From the Western perspective the main reasons for the anti-American resentment in the Muslim world is due to education, media and Anti-Americanism (Gentzkow, Shapiro, 2004). West counters: Even West is taking some of the measures to overcome this anti-American negative approach such as implementing the trade and aid programs to decrease economic inequalities, to change the unfavorable image, seeking support on U. S policy on Iraq, planning to developing new strategy on Arab-Israeli peace negotiations, influence positive open political systems etc. Conclusion: U. S is successful in brining gap between the Muslim world to an extent where it divided it into US allies, US enemies and Neutral countries basing on its relations. As a whole West is using all its strategies to change its image and forcing the Muslim world to react to against terrorism, the Muslim world persecution is different. But carefully watching Muslim world is aware of the West motives and started to have a common agenda and this will be fruitful in coming days. The statement â€Å"The anti-Muslim attitudes of West united the Muslim world† is justified by looking at the anti-Muslim factors causing the unification of Muslim world. Even though the West and U. S in particular are taking the measure to have a better image in the Muslim World, the Muslim community is expecting more and concrete steps at ground level rather than confining to the media statements.

National Prohibition in America :: Eighteenth Amendment

  Ã‚  Ã‚  Ã‚  Ã‚  National Prohibition, brought about by the Eighteenth Amendment and enforced through the Volstead Act, lasted for over ten years. Besides a growing lack of public support for both Prohibition and temperance itself, the outlaw of alcohol continued throughout the United States—at least in the law books. In practice, however, National Prohibition was much less effective than temperance and Prohibition leaders had hoped, in the end causing more problems than it solved. Once started, Prohibition led to the rise in crime during the twenties, the public health problems associated with bootleg liquor and alcohol substitutes, the problems between religious, racial, and the political rise in response to its presence.   Ã‚  Ã‚  Ã‚  Ã‚   Prohibition did enjoy some success. History revealed that alcohol drinking did drop after the National Prohibition and the Volstead Act. This lower on a national level was not all that much to the effect of recent problems in specific areas or communities. Also, after this drop alcohol drinking continued to rise through Prohibition to the point where it was thought drinking would actually pass pre-Prohibition levels. The same was true of alcohol related diseases while lowering, alcoholism and alcohol-related illness climbed to new heights, all while Prohibition was still in effect (Thornton, â€Å"Failure† 70–71). The initial ideas of Prohibition was reversed. Crime was a problem during Prohibition. Since demand does not generally lower or at least not greatly alcohol continued to be traded even though laws exist to stop those kind of problems. The black market increased the crime rate related to the making and selling of alcohol. â€Å"Prohibition creates new profit opportunities for both criminals and non-criminals,† especially for those previously involved in criminal activities (Thornton, â€Å"Failure† 116–117).   Ã‚  Ã‚  Ã‚  Ã‚  During National Prohibition in the 1920’s and early 1930’s—crime rate continued to raise as less and less people were willing to quit drinking or to respect the ideas of prohibition, as shown by the raise in fines given for Prohibition violations through its time. Crime quickly became â€Å"organized† for the first time, running activities contrary to Prohibition on a never before seen scale (Thornton, â€Å"Failure† 70). In fact, by the end of Prohibition, speakeasies had actually outnumbered the saloons of pre-Prohibition years, spreading the influence of alcohol over a much wider range (Thornton, â€Å"Failure† 72). Alcohol prices rose greatly due to the troubles of making and selling a prohibited substance especially among the working classes, to steal alcohol or to steal other things which could then be sold to pay for alcohol.   Ã‚  Ã‚  Ã‚  Ã‚  Prohibition was first meant to stop the abuses thought to be from alcohol, main problem was crime. As more and more people began to ignore

Kant, Categorical Imperative, And The Deontological Argument

Immanuel Kant, the Categorical Imperative, and the Deontological Argument Kant describes the categorical imperative as a universal law, one that is formed from a collective agreement. That agreement is further clarified by Kant; â€Å"I ought never to act except in such a way that I can also will that my maxim should become universal law.† Basically, we should not do something to others that we do not want done on ourselves. Through this idea, we can evaluate questions like â€Å"Is it ever acceptable to tell a lie?† I will argue that it is indeed acceptable to tell lies within certain circumstances, and that Kant’s deontological argument holds many exceptions. Before I start the exploring into our question, I first want to talk about Kant’s†¦show more content†¦Recall that Kant defines the categorical imperative as â€Å"Do unto others as you would have them do unto you.† (A bible quote, I believe). Let’s put ourselves in the shoes of the person asking the question. If we asked the question with honesty, seeking the truth, then the person answering should answer truthfully. However, you can also ask the question in a rhetorical way (teenagers do it all the time). In this situation, what the person wants is not the truth, but rather a playful response, and since we should be treating others the same way we would want to be treated, we would go along and be playful in this context of the question. The point is, the one question, â€Å"Does this dress make me look fat?†, isn’t necessarily limited to a single circumstance. I only gave two possible contexts of which the question may appear, but there can easily be indefinite amounts of possible contexts, and this applies to any question/situation. Another instance where lying is universal exists within the situation we all know as â€Å"job interviews.† And it’s not just the interviewee, the interviewer tends to lie as well. The intervie w lie is so common that it might as well be a universal law (categorical imperative, anyone?). Before I continue, here’s a disclaimer.
