Relationship between algae and tidepool chemistry

Relationship between algal cover and water chemistry in rockroses Mad Mukluks Mad Midair ABSTRACT Interstitial Rockford is one of the harshest environment in marine ecosystem. Most of the organisms living in it has to have adoptions to survive in harsh conditions, especially algal. A research was done to see if biotic factors such as temperature, dissolved oxygen, temperature and pH value could have a significant correlation with total percentage of algal cover. Initial hypothesis was dissolved oxygen and pH value are correlated to total algal cover.Each pool sample's water hammiest were measured and tested for 2 day period. The correlation between dissolved oxygen and algal cover is weak, proving that dissolved oxygen is not fairly important, where pH value has stronger correlation than the other chemical property tested. Most of the rockroses observed has high percentage cover of coralline algal. INTRODUCTION Rocky shore are coastal shores that are consists of hard substrates. It i s regarded as the most ecological part of the marine system (Library et al, 2012).Rocky shore has three zone; low, mid and high with variety of communities living on each interstitial matrix (Phenylalanine's, 2007). High interstitial zone has rockroses and go to several months without being replenished from the seawater (McAllen & Taylor, 2001). Interstitial Rockford have a relative stable environment where that has few changes in terms of physical conditions when the water reaches low tide (Kemp, 2009). Both McAllen & Taylor (2001) and Berkshire et al (1987) stated that rockroses undergoes many extreme physic-chemical conditions and few organisms are able to live in rockroses.These biotic factors have a significant influence in community dynamics and population (Theatrical, 2002). Thus, it has large abundance of specialized tax vying in rockroses, such as algae (Murals, 2013). The water chemistry of rockroses fluctuates rapidly when low tide, particularly oxygen concentration, pH v alue, temperature and salinity. Temperature and salinity is important for algae, whereas oxygen concentration and pH value is produced by algae. Oxygen is important to all living organism and the availability of oxygen in rockroses is low, which can lead to hypoxia to organisms living in it (Berkshire et al, 1987).However, high algal cover could increase the saturation level of oxygen in rockroses, but there is little research done on hyperemia on rockroses. Algae requires sunlight and carbon dioxide for photosynthesis, which in return produce more oxygen in rockroses. It will also produce hydrogen, which makes the Rockford more acidic. Temperature is also important, because the temperature in rockroses is relatively higher than normal seawater temperature. Increasing temperature could affect the algae in terms of physiology and actions of algae (Library et al, 2012).According to Kemp (2009), increasing water temperature can be caused by long exposure from sunlight and also the loca tion of Rockford. In a study done by Kemp at the coast of South Africa, he water temperature in rockroses were ranging from low ICC to high ICC during peak hours. Nowhere (1998) specified that sunlight has a tremendous effect on primary production in the aquatic system in rockroses. Salinity also can affect the water chemistry of rockroses.The changing level salinity of rockroses are varied according to location and geographically and it can be caused either by input from seawater during high tide, evaporation and terrestrial runoff or rainfall (Kemp, 2009). Ended et al (2014) showed that salinity has large role in terms of species richness in rockroses. The purpose of this study is to investigate if the total algal cover is being affected by the water chemistry in rockroses during low tide. The aim of this experiment is to observe the relationships between algal cover and water chemistry, especially dissolved oxygen concentration.I expected to see high level of oxygen saturation in rockroses due to photosynthesis. I also expecting high algal cover in alkaline rockroses. Since there is few fauna living in rockroses, I do not take them as measurement in this experiment because I more interested in functional algal group. From this, I deduced a hypothesis for this experiment. The hypothesis is percentage of algal cover is positively correlated with pH value and dissolved oxygen and negatively correlated with salinity and temperature.METHOD Location The study site was at Cape Palliates, southern most point in North Island and the experiment ran for three days, from February 1st to February 3rd 2014. Pool sample A transect line of 50 meter was laid out across the high rocky shore and began find suitable Rockford samples. I try to locate good pools sample with pool criteria of a depth of 1 CM, area around 2-mm and the presence of algal cover per pool. I assure depth of each pool by measuring the depth 3 times at different deepest point in the pool to obtain an aver age depth.The length of the pool is measured across by a measuring tape. A total of twelve pools that quite meet the measuring criteria similar were marked at high shore in a two day period. As a reference, one pool sample from lower rocky shore was marked and measured to compare water chemistry only. After pools were marked, a CACM x CACM quadrant were put on the pool, a Perspex glass layer with 25 random points were put on top of the quadrant. The quadrant is used to measure percentage of algal cover and functional algal cover y using point intercept method.Each pool sample has it chemical properties measured on the 2nd and 3rd of February Measurement of oxygen concentration Measurement of oxygen concentration was made by using a portable oxygen measurer that is measured twice, one when the water reached low tide and one an hour later for a maximum exposure from the environment. Measurement of salinity Measurement of Rockford salinity was made by using a refractors. The salinity w as measured twice, one when the water reached low tide and one an hour later for a maximum exposure from the environment. Measurement of temperatureThe temperature of the Rockford was measured by using a simple thermometer twice, one when the water reached low tide and one an hour later for a maximum exposure from the environment. Measurement of pH value The pH value of the Rockford is measured using a pH meter and measured twice, one when the water reached low tide and one an hour later for a maximum exposure from the environment. However, while measuring the chemical properties of Rockford, I discovered that 5 out the 12 pool sample has geographical problems, such as drainage, constant terrestrial runoff and shadowed that will alter findings.It was decided that problem pool samples was not counted, and 7 remaining sample is used for the experiment. Statistical analysis I used ASS Enterprise Guide 5. 1 to obtain the linear regression to see the relationship between algal cover with 4 water chemistry; percentage of dissolved oxygen, salinity, temperature and pH value. I also will use ASS to obtain the p-value of each correlation, regression (RE) and F ratio for each correlation.

Case Study 8-2 - Research Paper Example In addition, the union has failed to explicitly state in the CBA the terms of how they would raise their premiums, given the anticipated appreciation of premium rates. 2. I think that the interpretation of the union on the CBA was reasonable, given that the CBA explicitly stated that the percentage increase on the premiums to be paid by the workers, effective January 1,200, would be on the stated amounts as based from the 1999 premiums for the TOP. In this case, it can reasonably be argued that the premiums to be paid by the workers would be based on 1999 premiums; however, it is also the union’s fault that they did not clarify on whether the rates presented on the CBA were merely illustrative, or were the actual rates. 3. In this case, I think that the company also had the moral responsibility to explicitly state the terms of the CBA provision, so that there would be no confusion on its interpretation. On this specific case, it can clearly be seen that the premium payment fig ures stated in the CBA may be reasonable understood to be based from 1999 premiums, effective on the stated date (January 1,2000).

Gender Bias in Korea and Japan Essay Example | Topics and Well Written Essays - 1500 words

Gender Bias in Korea and Japan - Essay Example The social problem has been catalyzed by their almost similar beliefs in culture and traditions, which supports male chauvinism and dominance. The traditional woman in the Korean society is considered one that takes care of her family at home. The husband is the head of the house and is expected to fend for the family. These views are similar to those in the traditional Japan culture. To analyze the gender bias in the two societal set ups, this paper analyzes and compares gender bias in employment and education opportunities in the two communities. The Japanese and the Koreans had, and still have, similarities in their societies’ gender bias. The problem is highly attributed to the patriarchal system of the families in the two societies. Civilization has brought about changes in the way women are viewed in the society through introduction of the laws advocating for gender equality, but these laws are yet to be implemented effectively. Consequently, high level of gender bias still haunts these societies to date. Today, despite South Korea having one of the world’s highly educated workforces with 37% women and 42% men past college education, women are still very disadvantaged in the labor industry. The women have to balance between home commitments and the long working hours. This is as a result of cultural emphasis still prominent in the society that men are the breadwinners in a family and women the homemakers.

Toulmin Argumentation Essay Example | Topics and Well Written Essays - 750 words

Toulmin Argumentation - Essay Example The No Child Left Behind Act of 2001 is an example of the steps that the government has made in order to broaden the workforce in the military. It is an act requiring all public school teachers to be highly qualified by way of showing subject knowledge for their teaching level (Berkhart 104). While this act seems to be a very objective and a well-structured plan, the news regarding the number of students who are passing the military exams are alarming. According to Fox News, one in every four students who took the basic military exam – which is basic math, science and reading questions – has received a failing mark. It is for this reason that the military should be allowed, and thus, intensify their efforts of trying to recruit high schools in military. Also, Amy Wilkins, the vice president of the nonprofit Education Trust, such incident only gives us the chance to take a look at the civilian workforce. The result of the exam only shows that if the students were not rea dy for the military jobs, then they are most likely not also ready for the work in the civilian community. At this rate, the military should really be alarmed most especially if the choices they have are slowly diminishing by the number. With the concern of the student’s welfare, however, some are saying that the military has become more violent in pushing the students to apply for the Army. While on the other hand, some are saying that the military are only there, giving them the opportunity to guide them on what path to take. There are still some schools that are very professional when it comes to the area of recruitment (Trousdale 42). It can also be stated that the reason why some students feel that they are being pushed by the military is because they are not yet really ready to be of service to the Army. Being in high school, they still want to experience the freedom, and be carefree in anything they do. And to most students, being in the military is like imprisoning yo urself to so much discipline that the only way to become free again is to quit. But then again, as what Amy Wilkins has stated, if high school students are not yet ready for the challenges that the military is offering, then they are not even more ready for the challenges in the real world. Recruiting is a part of every organization. Of course, in order to maintain a number of members, recruitment is the key. And in this case, military serves as the national defense of the community. They are the ones who will fight for the country’s safety, and thus, their numbers should be tightened, let alone be increased. And not only that, the Army really needs a workforce that is educated and motivated so that they can defend the country real well. Recruiting is not about forcing these kids to go into war, but rather, opening their minds to the possible career opportunity in the military world. In fact, getting into military might be the best way to get them a college education. Another benefit from recruiting is that they implement motivation for the students to strive and work hard. They also encourage them to be disciplined by telling their own stories. By this, anyone can clearly see that the students are not being forced to join the military but is only facilitating the possibility of them joining the Army. After all, every one of us has their own free will and kids nowadays are smart enough to know what they really want in their life. It is never wrong to

Smoking among Teenagers Research Paper Example | Topics and Well Written Essays - 2000 words

Smoking among Teenagers - Research Paper Example Not only this but also a teen’s exposure to cigarette smoke increases the risk of metabolic syndrome. Smoking during the teenage impacts the teenager’s overall health, lung efficiency, reduces concentration span as a result of which his or her academic performance is hampered. Youth is that period of our lives where our mind and body are at their peaks but smoking during teenage deprives one of giving one’s best performance in all walks of life (Hales, 2009-2010). The hazards of teenage smoking and its causes can be traced to the determinants of health as per the ecological model. THE ECOLOGICAL MODEL The ecological perspective on health includes individual and environmental factors. The ecological model stresses that for community assessment, it is important to look beyond individual factors and also incorporate organizational and community factors. As per the ecological model, behavior at the individual level is influenced by biological, physiological, psycholo gical and emotional states. The psychological aspect of teenage smoking is that teenagers have it at the back of their mind that smoking makes them more ‘cool’ and mature. Many a times a teenager tries the first puff just to imitate his or her favorite celebrity. The social and cultural beliefs of family, friends and peers comprise of the interpersonal level. Smoking behavior of a teen is influenced by family: for instance if one of the parents smokes, then the child tends to smoke too. Heredity is the main biological factor: for instance women who smoke during pregnancy are indirectly making their unborn children prone to nicotine. These children develop a liking for nicotine and also show quick addiction. Friends are part family members and usually a teen is more influenced by friends than by his family. Many teenagers testify that their friends forced them to take the first puff (Harris, 2010). The physiological factors for teenage smoking will include nicotine metab olism and excretion. Cultural beliefs are very correctly depicted in the promotions of the Marlboro Man (McLeroy, 1988). At the organizational and community level, economic, physical and structural factors influence behavior. This level encompasses educational programs, mass media, counseling, support groups and organizational incentives. Public policy is another domain at which assessment can be done for a community. The Public Policy shows the state’s stance on health and related issues. For instance public service messages against teenage smoking and awareness programs come under public policy. Not only this but also public policy includes national laws for teenage smoking like a ban on selling cigarettes to a minor (Harris, 2010). Relationships with family, friends, neighbors, contacts at work, and acquaintances form the interpersonal processes which influence health behaviors. These relationships are particularly more influential in a teenager’s life as his mind i s vulnerable and he tends to adopt common behavior in his surroundings. The way a teenager deals with stress is also influenced by these relationships. If an adult smokes excessively during stress than his teenage son would do the same under stress. If the same interpersonal relationships can provoke a teenager to smoke then they can also work as support systems in times of stress and rehabilitation (for smoking or alcohol addicts). However if a

Is famine a natural phenomenon - Essay Example tion as to whether or not famine is man-made or a natural disaster, the following aims to explore the different causes of famine in a holistic perspective. It is reported that in Asia Africa and Latin America, the regions of the world which are underdeveloped, more than 500 million people live in absolute poverty. Accordingly more than 9 million people die each and every year due to hunger and malnutrition and starvation. Accordingly famine persists despite the fact that we have obtained a certain level of and development in the Western developed world and the result of income disparity is the increased incidence of famine throughout the world. What are the causes of famine? For many parts of the world famine is caused by a series of social, political, and environmental factors which have led to widespread poverty and hunger. In some places such as in Ethiopia, Somalia, and other countries of the Horn of Africa harsh envrionmental conditions and political instability have paved the way for famines and droughts. Droughts occur due to environmental factors and can be caused by a lack of rain one year, soil degradation, or the forces of g lobal warming. Environmental catastrophes have been prevalent throughout world history and famine can be traced back to biblical stories as well as to the early annals of modern civilization. In this respect then, famine can be seen as inevitable and as a feature of our existence on earth. Despite the fact that famine has existed since the dawn of time, there are also human made factors which can account for the rise of famines and poverty throughout the world. We now turn to the causes of human made famines and turned to exploration of our case study, Somalia. The African continent, although seen by many as the cradle of humanity and endowed with many natural resources, is home to some of the poorest countries on the planet. Many of these countries are beset by famine, arguably the greatest indicator of poverty known to

SELF INCRIMINATION Research Paper Example | Topics and Well Written Essays - 2000 words

SELF INCRIMINATION - Research Paper Example Two main principles of the Fifth Amendment therefore include protection of rights of persons undergoing criminal proceedings in the courts, to further support the premise of innocent until proven guilty. Secondly, the principle of prevention of prosecution conduct likely to compel defendants to give their own incriminating evidence takes shape in the Fifth Amendment. Judges cannot compel individuals before court to give information that would directly affect negatively in their pursuit of exoneration in court proceedings. Other persons with an interest in the case cannot compel the defendant to give evidence against themselves within the precincts of the court (GetLegal, 2012). The Fifth Amendment therefore controls any influence that could alter the defendant’s opportunity to present their case before court with confidence that they will not face undue pressure to incriminate themselves, thereby destroying their enjoyment of right to be innocent until proven guilty. Another emergent theme in the Fifth Amendment is the active separation of powers in criminal proceedings, where the executive faces barring environment against use of force on witnesses’ rights. The interpretation of the Fifth Amendment has however faced various contestations with regard to the parties and conditions against which the Amendment gains enforcement authen tication. In Miranda v. Arizona, a case that took place in 1966 the United States Supreme Court defined the admissibility of evidence obtained irregularly from the defendant, particularly within the conditions of absence of an attorney to guide the defendant during questioning. According to the court’s argument, obtaining exculpatory and inculpatory statement in gathering prosecutorial evidence exposes the individual to conditions that may violate their own constitutional rights of informed consent. The right against
