What impact might mitigation of diffuse nitrate pollution have on river water quality in a rural catchment The article entitled â€Å"What impact might mitigation of diffuse nitrate pollution have on river water quality in a rural catchment?† by Michael Hutchins, studied the role played by nitrate loads in freshwater. The investigator carried out the study by evaluating how phytoplankton growth is affected by nutrient and light concentration. On one hand, the assessment of nutrients concentration was done by the measurement of annual mean concentration sourced from periodic regulatory monitoring. On the other hand, the effect of light was assessed using data sourced from solar radiation and sediment monitoring data. The investigator went further and assessed areas in the river under study that had sufficient calm water that could facilitate the growth of phytoplankton. This was done using hydraulic data collected from river network model applications. The researcher then went further and developed an analysis of the effect of the changes on land management in the nitrate concentrat ions in the river. This was carried out using estimations from NALTRACES, a nitrate model. An analysis using NALTRACES concluded that as much as agriculture contributes to increased levels of nitrates in the river water, its effect on the growth and concentration of phytoplankton is negligible. The study also found out that the growth of phytoplankton is regulated by the amount of sunlight that is able to infiltrate the water. In fact, areas that allow maximum light infiltration into the water promote extensive growth of Phytoplankton even if the levels of nitrates in the water are very low. Therefore, the investigation concluded that nitrate concentration is not one of the conditions that determine the growth of phytoplankton in the river water. The investigation concluded that developing a means of regulating the amount of light reaching the water is an effective way of regulating the growth of phytoplankton. It also suggested the establishment of a riparian tree cover as one of the ways that can be used in the regulation of light availability in the river water. Data was gathered and analyzed using a variety of simple modeling approaches to arrive at the conclusion that an effective way of mitigating phytoplankton growth is by minimizing illumination on the water surface. Critique The article by Hutchins is researched well, and the conclusions developed from the findings are well founded and backed by a good number of previous investigations. The conclusions are well founded because they are derived from the collected data. In addition, the conclusions are achieved after the collected data is critically analyzed and evaluated. The methodology applied in the investigation is effective enough to provide an explanation to the research issue. This is because it involves the collection of primary data as well as secondary data (Hutchins, 2012), which assists in explaining terms used in this research. The investigation applied a correlation analysis of nutrient level and phytoplankton growth, resulting to the development of a conclusion that had enough evidences that backed it. The evidence was derived from the data in the correlation analysis. In fact, the data used in the research acted as evidence for the conclusions made. Furthermore, data regarding sunlight ill umination and phytoplankton growth was used in the development of a sound analysis. From this analysis, it was concluded that it is one main factor that if controlled, the growth of phytoplankton can be fully regulated. On examining the sources used in this review, we notice that all sources are academic and written by well-known authors and published in credible journals. In fact, most of the studies referenced in the investigation were conducted between the years 2003 and 2012. Therefore, the sources cited in this article are the latest with respect to information portrayed in the article. However, the article has provided a stand that contradicts many recent investigations that link phytoplankton bloom to increased nutrient levels in water. Xu et al (2010) proposes an approach of regulating phytoplankton bloom in Lake Taihu that basically involves an approach aimed at lowering the lake waters nutritional levels. From their study, it was evident that phytoplankton bloom in the lake is directly associated with increased leaching of nutrients into the lake waters. On the other hand, Hutchins (2012) argues that nutrient levels have no form of association with phytoplankton bloom. This assertion is not founded since effects of human activities lead to unnatural forms of occasions. The sun is always constant, and its effects with relation to phytoplankton bloom are directly proportional to the levels of nutrients available in the waters to effect growth. As much as his conclusion links the reduction of illumination in the river as an approach towards managing the growth of phytoplankton, the application of this approach is quite limited and time consuming. In most cases, it might take several years to manage the problem by developing a means of regulating sunlight. According to a study by Lewis and Wurtsbaugh (2008), the phytoplankton growth limiting effect of nitrates is not universal. It is common in waters found in the high altitude tropic regions, which are not the case of the location of the river analysed in the study. The author also mentions phosphorus as a mineral that has no effect on the concentration of Phytoplankton; this stand contradicts a study by Sylvan and his colleagues (2006), which provided an inverse proportionality of the concentration of phosphorus to the concentration of phytoplankton. Therefore, the assumption adopted by Hutchins (2012), in his investigation required a deeper clarification on the approach adopted on arriving at the conclusion of delinking mineral concentrations to phytoplankton growth in the river. For the case of this river, I think a study that specifically analyses the extent to which nutrients affect the growth of phytoplankton is the best approach that will provide practical and applicable findings and recommendations. An in-depth analysis of the impacts of each nutrient to the growth of phytoplankton is necessary. Furthermore, this article is limited in its approach to developing a recommendation that aims at limiting the sunlight accessing the water in the river. As much as he assures the reader of the effectiveness of that approach, it is less viable due to several issues, including cost and time factor. In conclusion, as much as this article enriches the available level of understanding on management of Phytoplankton, its limitation in terms of applicability of the findings limits the effectiveness of the study with relation to the topic of the paper.

Chicago Referencing †4 Things You Should Know

Chicago Referencing – 4 Things You Should Know Chicago Referencing – 4 Things You Should Know Chicago referencing is a flexible system for citing sources in academic writing. If it’s your colleges chosen system or you’re writing a paper for a journal, knowing how to use Chicago referencing is vital. Before you set to work, though, there are a few things you should know. 1. The Chicago Manual of Style Chicago referencing is set out in The Chicago Manual of Style. The 16th edition of this was released in 2010 and includes details on every aspect of editorial practice, from grammar to formatting. In the U.S., The Chicago Manual of Style is commonly used by publications in the social and human sciences. However, if your college simply specifies â€Å"Chicago referencing,† it’s only the rules for citing sources that you need to worry about. 2. One Manual, Two Styles Chicago referencing can be a little confusing because it incorporates two citation styles: author-date citations and a footnote and bibliography version. Author-date citations use a style similar to APA referencing, with the author’s surname, year of publication and (if relevant) page numbers given in brackets: The New World was colonized around 11,000 B.C. (Diamond 1997, 67). This is accompanied by full publication detail in a reference list. The footnote and bibliography system, meanwhile, cites sources with superscript numbers (e.g., 1, 2, 3) in the main text. You can then give source information in footnotes (as well as in a bibliography). The first footnote for the source named above, for example, would appear as: 1. Jared Diamond, Guns, Germs Steel: A Short History of Everybody for the Last 13,000 Years (London: Vintage, 1997), 67. The fact there are two citation styles within Chicago referencing makes it crucial to check your style guide before you start writing. 3. Subsequent Citations If you’re using the author-date system, citing the same source more than once simply requires giving the author’s name and year of publication each time. With the footnote and bibliography system, however, you can shorten subsequent citations of the same source. For consecutive citations, you can use the Latin term â€Å"Ibid.† For nonconsecutive citations, give the author’s surname, a shortened title and relevant page numbers: 1. Jared Diamond, Guns, Germs Steel: A Short History of Everybody for the Last 13,000 Years (London: Vintage, 1997), 67. 2. Ibid., 112. 3. Derek Author, A Different Book, (New York: Publisher Inc., 2005), 45. 4. Diamond, Guns, Germs Steel, 23. 4. Reference List/Bibliography The two citation systems covered by Chicago referencing use a similar format for creating a reference list/bibliography, but there are differences. The information required for a book in a reference list when using the author-date system is: Author Surname, First Name. Year. Title. City of Publication: Publisher. With the footnote and bibliography system, on the other hand, publication information should be presented as follows: Author Surname, First Name. Title. City of Publication: Publisher, Year.
