Use of Drones in Field Biology

Words: 468 Length: 2 Pages Document Type: Essay Paper #: 15196433

Marine Biology & Drones

Drones are being used with increasing frequency in the study of marine life, including for population counts, and behavioral studies. The news media has offered up dramatic images of studies underway, for example of orca populations off the coast of British Columbia, but there are many studies around the world that are using drones. The advantage of drones is that they can fly above marine environments, providing an overhead view of those environments. This can be valuable in terms of counting animal populations for example, because with drones animals typically do not change their behaviors (Schiffman, 2014). Drones have become a popular tool for field biologists in part because drone technology is improving and the cost of these devices is falling (Schiffman, 2014).

In some fields, such as the observation of marine life in Antarctic sea ice, it has been noted that the normal observation is…… [Read More]

Dolphins commonly bear one calf at a time. Reproduction occurs every 2 to 3 years and as many as 8 times within their life span (each-Net Online).

Feeding

Fishes are the typical foods of dolphins. Calves (young dolphins) start to eat fish at 3 to 4 months. Adult dolphins can eat up to 14 pounds of fish in a day (each-Net Online).

Predators

Dolphins' predators are the sharks. Sometimes, killer whales also feed on dolphins.

Are dolphins endangered?

Dolphins are endangered. Their population is not yet known however because different types of dolphins can be found in different parts of water around the globe. Following is a list of the endangered species of dolphins.

Biology Qs the Primary Source

Words: 829 Length: 3 Pages Document Type: Essay Paper #: 82910581

Most fungi can also reproduce through sexual reproduction both with the same organism mixing gametes and with reproduction between two separate organisms. The cells of many fungi are primarily copies of each other, without differentiation of organs (except in the fruiting sections of the organism, such as the mushrooms and molds typically visible and known to humans).

6)

Fungi are considered a separate kingdom for several reasons. They are different from plants in their inability to produce energy from sunlight, and in fact most grow in dark places. Unlike animals and many protozoa, they cannot move; unlike most protozoa, they exist almost entirely as multicellular and colonial organisms.

7)

The various classifications of fungi are determined based on their method(s) of reproduction. Zygomycota produce both asexual and sexual spores, while Basidiomycota rarely produce asexually and produce a different type of sexual spore. Ascomycota produce asexual spores, and can also grow…… [Read More]

Biology

Species within a given population will differentiate due to a sudden and dramatic geological or climatological change. If a volcano erupted on an island like one of those on Vanuatu, the populations of local geckos would start to differentiate depending on where members of that population were before and after the eruption.

Statement/Hypothesis: If a volcanic eruption led to lava flows on one side of the island, but not on the other side, then the gecko population would differentiate based on the availability of food sources and also based on the remaining predators.

Geological Event: A volcano erupts on a small tropical island, part of the Vanuatu group. The types of observations necessary for the evaluation of the impact of the volcano on local lizard (gecko) species include size (length), coloration and visual patterns, and vocalizations. Behavioral observations would include territories occupied, feeding patterns, and mating patterns.

This discovery could lead to cleaner energy, including the technology that could be used by factories and cars to capture carbon dioxide before it reaches the atmosphere. Carbon dioxide is polluting the Earth's atmosphere along with damaging coral reefs and marine life and has impacts that are irreversible. Scientists believe that this will be important for potentially getting to a viable carbon dioxide-capture material with ultra-high selectivity. They are optimistic that is within their reach. Potentially, they think that they could create a material that could convert carbon dioxide into a fuel, or a material that can separate carbon dioxide with greater efficiency (Chemists Create Synthetic 'Gene-Like' Crystals for Carbon Dioxide Capture, 2010).

Environmental Biology: The Effects of Pollution in the Ocean

The oceans are being contaminated by pollution caused by oil spills, tanker discharges, untreated municipal wastes and agrochemical residues. Pollution is known to have destabilized many coastal ecosystems and is believed to be responsible for the decline in phytoplankton and consumable shellfish which usually thrive further out to sea. Medical wastes, beach visitors' garbage, waterfront businesses account for most of the toxic and most dangerous pollutants that lurk below the surface of the ocean. Oil spills and medical wastes only play a small part in ocean pollution (Energy Intelligence Group, 2002). Plants and factories spew over thirty-two billion gallons of poisonous chemicals and sewage into the sea every day. The Commerce Department's National Oceanic and Atmospheric Administration (2000) states that eighty percent of pollution to the marine environment comes from land-based sources, such as runoff pollution. Runoff pollution includes many small…… [Read More]

Meaning of Biology and Its Different Fields

Words: 641 Length: 2 Pages Document Type: Essay Paper #: 88285491

Biology?

The word biology means the study of life. It is a combination of "bio," which means "life," and "ology," which means "wisdom" or "science of." Thus, the term itself tells us what its meaning is: it is the science or study of life.

However, there are many fields in biology, which look at specific sectors or areas of "life." Because life on this planet is abounding and so complex, it is required that there be several fields of biological science. For instance, marine biology studies life in water (such as in oceans or lakes). Human biology studies the complexities of the human body. Cellular biology takes an even closer look at biological studies by closing in on the activities and structures of cells, which are just one part of life.

Advancements in biological knowledge have taken place over many centuries throughout the history of the world. In fact, all…… [Read More]

Words: 599 Length: 2 Pages Document Type: Essay Paper #: 42945604

The role of the current in trajectory movements is significant, particularly in species such as the leatherback turtle, as it provides at times unexpected information regarding the animal's sense of direction and purpose in terms of its environment. In the conservation effort, it is therefore very important to consider the influence of current upon animal movement.

3)

Conservation can only be effectively applied when behavior and movement are interpreted to the highest degree of accuracy. The study reveals the importance of current influence on marine life movement. Although larger and faster marine animals will not be as influenced by the current as the leatherback turtle, there will certainly be an impact. While important to study the movements of marine life, the influence of currents on the study of foraging behavior is even more important. This will determine the focus of conservation on specific foraging areas in order to ensure sustainability…… [Read More]

Red Tides on the Gulf

brevis blooms are not a new phenomenon, and fish kills that result from red tides caused by K. brevis in the Gulf of Mexico have been described in the scientific literature since 1960 or so and have been reported anecdotally for more than two centuries (Naar et al. 2002). In this regard, Backer and her associates (2005) emphasize that, "The human health effects from consuming shellfish with high concentrations of brevetoxins in their tissues have been well documented. However, there is very little information describing human health effects from environmental exposures. It is ironic that we know the least about the aspects of the Florida red tide problem that poses the greatest public health hazard in terms of number of people affected" (645). Today, K. brevis blooms are monitored closely in order to mitigate the foregoing health hazards that are related to the consumption of shellfish and shellfish harvesting is…… [Read More]

The fact is that numerous rooted macrophyte structures are not full of naturally strong and healthy particles and sediments and nutrients. It is because of the restriction or absence of these particles, sediments and nutrients that the study of these systems has not been as extensive and thorough as the concentration on the terrestrial structures when understanding the fate, sources and sinks of Co2 levels in the ecosystems and the plants structures (e.g., Drake and Leadley 1991). Researchers assert that "rooted macrophyte systems can be sources of CO2, Chapter 4 and other gases through microbial processing of organic matter in the sediments and direct emission from leaves" (Delaune et al. 1990).

Sea around Us

Rachel Carson was a scientist and author who took a topic which had hitherto been only of interest to fellow scientists and opened it up to the masses. During her lifetime, she took up many causes in support of wildlife and the protection of species and protecting the natural landscape from potential molestation from developers and others who would destroy indigenous habitats. Among her many missions was to make people aware of the hazards of certain chemicals on the environment, such as pesticides on vegetation. In Rachel Carson's book The Sea around Us, the author strives to explain the mysteries of the sea. She begins with a discussion of the world of water from before recorded history, all the way up to the book's present which was the early 1950s.

An onlooker into the courses taught by this professor would be surprised and little confused as to Robert McCollough's style. Robert strives to know each of his students individually, to the point that he can refer to them with nicknames and hash out class discussions in an almost informal manner. Students admire his candor and passion for knowledge, and are drawn to his courses. Somehow it is this magnetism that results in the ultimate success of his students, and with a class average of 4.0 it is no mystery that Robert McCollough is a student and university favorite.

Psychological Testing

Psychological Testing

When one hears the phrase "psychological testing" one might be inclined to think of a test to determine one's mental health, a test that could tell someone whether she or he was crazy or not. But psychological testing is hardly so clear-cut, nor does it deal with the highly subjective subject of sanity. Psychological tests instead measure a range of qualities and potentials, including one's aptitude for various kinds of jobs, one's IQ, one's cognitive functioning, one's ideal occupation, and one's personality type. There are also specific psychological tests for certain mental illnesses, such as depression. In this paper I will briefly describe the different types of psychological tests before addressing the concepts of validity and reliability.

All psychological tests share the basic criteria of any type of test. Tests are sets of either exercises or questions (or some combination of the two) that are used in a…… [Read More]

This study conducted by the department of ecology and marine biology of the University of California analyses the factors that contribute to the reproductive success of the plant CLARKIA UNGUICULATA. The purpose of the study was to research the possibility of the allelic variations affecting the male and female reproductive functions. For the study the researchers took pollen donors homozygous for C. And . alleles. The researchers used both selfed and out- crossed pollination using different homozygous pollen donors.

The tests were performed under both competitive (more pollen) and non-competitive conditions with mixed pollination. The amount of pollen used was also varied (high, medium and low) so as to discern the pre-fertilization performance of the pollens from their post fertilization performance. (Viability, abortion). All the plants used in the study were selected from the same place and the seedlings were germinated under same conditions.…… [Read More]

Similarly, this type of non-invasive acoustic and vibrational monitoring has been used by doctors to get a better assessment of in vivo hip conditions so that they can better comprehend things like total hip arthroplasty (Glaser et al., 2010).

Acoustic Signals

"Acoustic emissions are elastic waves generated by a rapid release of energy at a localized source. They are produced by events such as particle impact, gas evolution, boiling, phase transitions, precipitation. Some processes produce emissions that can be heard. A lot more emit either outside the audible frequency or at too low an intensity to be heard (McLenna, 1995, p.338). Using non-intrusive acoustic monitoring is definitely a way to monitor an entire structure continuously and effectively (Wu & Abe, 2003).

The massive mollusks still do seem fantastical. Several of the irrational elements of 20,000 Leagues Under the Sea seemed more outrageous in the 19th century they do now. However, the novel continues to encapsulate the fantasy and science fiction genres because of its willingness to expand the boundary of what is real. Interestingly, 20,000 Leagues Under the Sea did not stretch those boundaries much further than hard science has.

On the other hand, novels such as the ones in the Twilight series are more squarely fantastical. Barring any major scientific discoveries, vampires and shape-shifters simply do not exist. Such elements of the absolutely impossible serve various literary functions. For instance, in New Moon Stephanie Meyer uses vampires and shape-shifters to develop the central character, a human being. As in Frankenstein, the impossible becomes the best means to explore human motivations, dreams, desires, and weaknesses.

Environment Influences the Body Plan of Organisms

The distinction between adiata and Bilateria, or organisms with a radial or bilateral symmetry, is that the latter have a dorsal/ventral polarity resulting in bilateral body axes (reviewed by Martindale and Henry, 1998). By comparison, species with radial symmetry, the adiata, have a single anterior/posterior axis in their body plan and no dorsal/ventral polarity. Another general distinction is the presence of three germ layers in the Bilateria, which are the endoderm, ectoderm, and mesoderm. These three pluripotent cell types will give rise to organs and internal epithelial layers, skin and nervous tissues, and muscle and connective tissues, respectively.

Biomimicry in Design

There is a set of trends in the 21st century regarding urban design, product design, and organizational studies. One of these trends is the act of biomimicry. Biomimicry is a design philosophy or perspective that mimics design patterns in nature. Products inspired by biomimicry are ecologically sound in design, production, and distribution processes, as well as solve human problems. Products reflecting biomimcry do not simply mimic the models, systems, processes, systems, and elements of nature for inspiration. These products mimic nature not only in design, but also in function as products of biomimicry solve problems. The design of nature avoids, anticipates, and solves problems. Thus the products inspired by nature do not mimic nature on a superficial level but on deeper levels of utility and sustainability. This paper will focus upon products that biomimic sharks. Using primary and secondary sources, the paper will evaluate the efficacy…… [Read More]

Computing Pollution

Words: 1180 Length: 4 Pages Document Type: Essay Paper #: 82536596

Computing Pollution

Computers are being used in applications that gauge the pollution in the air and water and other areas of the earth environment. These applications are useful in determining the source of the pollution and in assisting in informing researchers what might be done to reduce such pollution.

Air Pollution Emission

One such application in computing pollution is described in the work of Emad, Sayed, and Kassem (nd)[footnoteef:1] who report that smoke is one common source of air pollution. Specifically stated is that the "rising process of smoke depends on atmospheric ambient, meteorological conditions, emission parameters, such as the atmospheric stratification, initial emission momentum and temperature, wind direction and speed as well as turbulent behaviors, and so on." (Emad, Sayed, and Kassem, nd, p.1) The smoke dilution process and scope are of great interest to environmentalists since regional air quality is affected critically by dispersion of pollutants. eported as…… [Read More]

2005). The rules for deep-sea life are different than those for terrestrial species. Stratification plays an important role in species classification in vent environments. As the chimney grows in height the environment changes.

Tarasov and associates believe that deep-sea vents have a longer evolutionary history then shallow vents found closer to the surface. This is an important factor in understanding how hydrothermal vents are connected to early life on planet earth. Deep-sea hydrothermal vent communities represent a different phenomenon than shallow water vents. The chemical processes that take place in the deep-sea vent communities are very different from those in shallow areas. Shallow vent species receive light from the sun and more closely resemble terrestrial life forms. However, this is not so with deep-sea forms. Hydrothermal plumes are a rising column of hot water that can have sharp definitions in microhabitats. Similar species found inside the plume and outside of…… [Read More]

The Delta is also a habitat for many species of fish, birds, mammals, and plants, and it supports agricultural and recreational activities while also being the focal point for water distribution throughout the State.

The development of the Delta as it exists today started in late 1850 when the Swamp and Overflow Land Act transferred ownership of all swamp and overflow land, including Delta marshes, from the federal government to the State of California. In 1861, the State Legislature created the Board of Swamp and Overflowed Land Commissioners to manage reclamation projects, and in 1866, the authority of the Board was transferred to county boards of supervisors. The Delta now covers 738,000 acres interlaced with hundreds of miles of waterways, with much of the land below sea level, relying on more than 1,000 miles of levees for protection against flooding. 20

He is extremely wealthy and powerful, but psychologically somewhat fragile. In order to help face his problems, Happer engages an "abuse therapist" to hurl various forms of ill treatment at him. He is also interested in furthering his chances of immortality. He addresses this need by compulsively scanning the skies for a comet to bear his name. This relates to the theme as a whole in its commentary on how fleeting and futile the world of business is.

" (SD, 1)

McClintock goes on to connect this to pointedly negative consequences for marine life, arguing that many invertebrates are distinctly vulnerable because their protective shells require many of the nutrients naturally available in their surrounding water to maintain hardness or to develop at all. This is a concern which is also raised in the article by Monroe (2009), where the results of an experiment designed to confirm this effect were as expected. Accordingly, "[Victoria] Fabry, a biological oceanographer and visiting researcher at Scripps Institution of Oceanography at UC San Diego, studies the effects of ocean acidification on the mollusks known as pteropods. In one experiment, only 48 hours of exposure to slightly corrosive seawater caused normally smooth shells to become frayed at the edges on their way to eventual dissolution, severely diminishing their owners' chances of survival."

Consider the following quotation in which he reflects on the companionship between him and his peers.

ar is brutish, inglorious, and a terrible waste. Combat leaves an indelible mark on those who are forced to endure it. The only redeeming factors were my comrades' incredible bravery and their devotion to each other. The Marine Corps training taught us to kill efficiently and to try to survive. But it also taught us loyalty to each other -- and love. The esprit de corps sustained us (Sledge 152).

This passage provides a very vital means on interpreting many of the different events discussed within this memoir. It also answers a lot of questions in regards to the author's true esteem for war, which does not appear to be 'necessary' whatsoever.

Ecological Balance of the Coral

It should not be a difficult question to answer: we must begin reducing ocean pollution and taking steps to prohibit overfishing of our ocean shallows.

The plan that is formulated to address the overfishing and man-made pollutants in the coral reefs must be conducted by authorities in marine and ecological sciences. It must be conducted on two levels: the fishing industry associated with the catches on the coral reefs; and the pollutants that are introduced into the coral reefs through contact with man. This can be done by monitoring commercial tourism and diving industries, which claim there is no residual effect on the coral reefs (Carrier, James, and McLeod, Donald, 2005, p. 315).

Sociologists do not see war as something humanity is genetically programmed to do, but the result of social forces. Why do they believe this? What is the evidence? If war is not caused by biology, what are some of the social forces that sociologists argue have contributed to it? Illustrate your points with concrete examples from the readings.

According to Howard Zinn, there is no evidence that human beings are innately predisposed to war, biologically or sociologically. War is generated by the actions of governments, not individuals. Zinn justifies his contention by the fact that citizens must be urged through propaganda and monetary rewards to die for the state. This shows that all wars are innately unnatural and totalitarian, given that the state demands that citizens act against their personal interests, such as living to see their children grow up, to die for an abstract concept such as 'national security.'…… [Read More]

Biological Diversity of Today

Words: 929 Length: 3 Pages Document Type: Essay Paper #: 65561239

Biodiversity Defined

Biodiversity is a term which refers to the amount and degree of diversity found within living biology. Biodiversity is likely best measured as the sum total of the number of existent creatures, systems, and variety of creatures found within the world at large (National Geographic, 2016). In order to best understand the significance of this statement, it is necessary to codify biodiversity into three different varieties. There are ecosystems, species, and genes which comprise all of the variety found within the notion of biodiversity (National Wildlife Federation, 2016). Therefore, all that is needed to determine biodiversity is to simply add the number of each ecosystem, species, and gene variation found.

The importance and benefits of biodiversity

Biodiversity is important because of the way that different living systems found within it interact with one another. Oftentimes there is a degree of dependence between those systems. It is worth noting…… [Read More]

" Because of the ability to reproduce in large amounts in a small amount of time, phytoplankton are considered as the first link in the food chain of nearly all marine animals. Phytoplankton provide food for a large variety of organisms, including the microscopic animals (such as the zooplankton), bivalve molluscan shellfish (like mussels, oysters, scallops, and clams), and small fishes (such as anchovies and sardines). To continue the food chain, these group of animals then provide their own kind of food to other group animals like crabs, starfish, fish, marine birds, marine mammals, and humans (Karl, et al., 2001).

Individuals of all ages love to sail the oceans, swim in the sea and soar under or speed across the waves. It comes as no surprise, then, that some part of the human psyche remembers millions and millions of years ago before animals came on shore. What is still questionable is how or why these animals made the move from water to land. The journal articles discussed below give some of the latest findings on this topic.

Early in the Devonian Era, close to 400 million years ago, all the continents were grouped closely together and surrounded by the seas.

Behavioral Episodes in elation to Leopard Seals

Leopard seals are widely known for their ferocity and have been acknowledged as top predators for a long time now. These are large but slender mammals, with females usually exceeding males in size and weight. The spotty coats, distributed along their bodies, define the leopard appearance and allure to the hunting abilities they possess. With powerful jaws and canine teeth, leopard seals can prey on creatures of whatever size. Their agility and reputation have long formed individuals' negative perception upon the former. This document is to try to dismantle the negative image leopard seals have been inoculated with for such a long time. This proposal looks at some of the facts that have led people forming drastic opinions as well as some episodes that appear to indicate how little we may in fact know in relation to leopard seals.

omen in Combat

The participation of women in the war against Iraq has once again focused attention on the question of women in the military.

Many have argued that because of biology and psychology, women are inherently unsuited for military life in general and to combat in particular. However, this argument ignores how women's participation in the military has steadily increased since the Korean ar. Today, women can now attend public military schools and are eligible for promotion to the highest ranks. This paper argues that as women's role in society continues to evolve, then so must the role of women in the military. This includes allowing women to serve in combat positions during times of war.

Those opposed to women in the military base their arguments on the assumption that biological differences between men and women make women unable to fulfill combat duties. Syndicated columnist Mona Charen, for example,…… [Read More]

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.

iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.

Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

Environmental Hazards as a Consequence of Crude Oil/Natural Gas Exploration, Transportation, Refining and Storage

Ever since crude oil was first successfully drilled in the U.S. In Titusville, Pennsylvania, in 1859, the demand for oil has only been increasing over the years in countries all over the world. (Camden, 1883) Crude oil, from which various petroleum products are obtained, is a naturally occurring hydrocarbon component found trapped in rocks below the earth. The word "petroleum" means "rock oil" or "oil from the earth." Natural gas is another form of hydrocarbon that is also found in nature. oth crude oil and natural gas have excellent combustibility and are good sources of energy. Crude oil is not used in the extracted form; but it is refined to obtained products such as gasoline, liquefied petroleum gas (LPG), naphtha, kerosene, gas-oil and fuel oil.

The chemical was found to turn on quorum sensing in V. fischeri, whereas it inhibited pathogen Pseudomonas aeruginosa. Also, the slow-release was shown to be far more effective than by applying the chemical directly as an aqueous solution. Since quorum sensing is also important for pathogen establishment this application could be important for inhibiting pathogenic bacteria from colonization of internal medical devices.

In summary, the V. fischeri and squid symbiotic relationship is an important model host-bacteria system. Aspects of colonization of host-symbiont and host-pathogen have been shown, using the V. fisheri and squid model, to be the same. Therefore, understanding the mechanism and complex transcriptional regulatory systems of V. fischeri could lead to potential new therapies and pharmaceutical applications. Likewise, understanding the environmental factors necessary for successful host-bacteria interactions could lead to novel drug targets.

Rise of England's Military to 1688

Words: 2709 Length: 10 Pages Document Type: Essay Paper #: 71488409

English military to the year 1688. In order to undertsand the history of the English military, we must first examine the history opf England itself. The military has always been beholden to political and cultural factors and several developments in technology have changed the face of warfare and, by extension, the development of the military.

In the year 1688, King James II was forcibly removed from power and replaced by William of Orange. James II was a Catholic, and determined to reinstate Catholicism in England. After the birth of James' son and heir, a party of elder statesmen officially invited William of Orange, a Protestant, to come to England with a conquering army to save the kingdom from the Catholic rule of James II. This was known as the Glorious Revolution.

Otherwise more data and creative solutions would be required in order to get some sense of how to maintain eel populations. The notion of doing a population survey in the Sargasso Sea is tempting, although it is difficult to see how this would be accomplished. Perhaps serious monitoring efforts on the return of the juveniles -- taking the place of harvesting of these juveniles -- could give some sense of the abundance of the species on a yearly basis. Otherwise a fishing ban or limit on the adult eel could be enacted if the numbers are as seriously depleted as is feared. But obviously the unusual life cycle makes the commercial farming of eels extremely difficult, as they do not mate in captivity. If this could somehow be accomplished, it would be a useful way to raise the numbers of the species.

Evidence of this can be seen with the company being slow to provide information, on the total amounts of oil that are leaking into the ocean and the various restrictions that they have placed on media coverage. (Lack of Transparency Afflicts Oil Spill Response 2010) This problematic, because when there are restrictions and the company is slow to release information, it appears as if they have something to hide. At which point, the public will become furious with the company, from their perceived unwillingness to cooperate. This could have negative political fallout, as various Congressional Committees and regulators will demand all documents relating to the spill. Once this take place, it sets the stage for an ugly showdown with Congress and the White House. Where, they could seek to force the company to disclose more documents and engage in criminal investigations, as these actions give the appearance that executives are…… [Read More]

change is found and the second is to analyze where it is located in Parker's Western Way of War. These changes can be classified in any one of the three ways namely that of "fits and starts, punctuated equilibrium, and continuity."

Geoffrey Parker was the man who came up with the initial proposal for the Western means of War in his book. He put forward this concept to be studied further and in greater detail than before. This man had much to say about that concept. For instance, in his view throughout the history of western warfare there have existed a common set of practices which appear again and again -- generation after generation. Parker believes this is why the history of the west is a history of victory. In his opinion this also explains why the west has nothing to fear from any army save for themselves (Parker, 2000).…… [Read More]

Technology's Attempts to Address the Human Need in the Modern and Post-Modern Ages

Literary rouping One: The crisis of World War I and the lie of a technology's ability to sustain the human body and soul

as!" With this one word, Wilfred Owen's poem "Dulce Et Decorum Est" encompasses the sense of failure that many soldiers felt, regarding the promise of technology, throughout the duration of the First World War and during its immediate aftermath. In the previous era of capitalist industrialization, technology was seen, as part of the progressive movement and mechanized progress, as life giving and life-sustaining. However, the lie, in Owen's poem, of the value of technology, runs just as deep as the lie that it is sweet to die for one's country. The innovations of technology simply yield new ways for humanity to destroy other humans, based on arbitrary national groupings.…… [Read More]

Grouping Three: In a technological World, who is the 'I' that is writing this paper?

Samuel Lilley's 1914 text Past, Present and Future stressed the need that those who forget the past will have to repeat the past, until they learn its lessons. He wrote on the eve of war, in 1914, that history was the science of the future. To understand history, he suggested, is to understand humanity. However, this idea has since changed over the course of the 20th century, as science, has become the dominant modality of understanding the human condition and the perceived source of the reasons for the trajectory of humanity's evolution as a species.

The works of the soldiers of the first category of readings created a dichotomy of the 'natural' world of gas-free lungs and butterflies contrasted against the mechanized world of civilization, Latin, and the false glory of war. However, John R. Searle, whom addresses Consciousness as a Biological Problem from a late 20th century and early 21st century perspective implies that such impulses to violence are also natural and hardwired into the human, biological condition that creates the necessary conditions for warfare itself. To understand war, one must understand human biology rather than human history. The brain itself causes a sense of specificity and subjectivity, whether it is having a relationship with a machine, an element of the natural world, or another human being.

Nevertheless, it is a conceptual change from government-sponsored conservation efforts of the past, which might have focused specifically in the same region on the manatee population, and thus played a pure game of numbers. To regard the Florida manatee instead as part of a larger ecosystem that must be monitored in numerous different ways requires a change in approach which is not always easy for a government agency to implement.

2. The chief conservation implication of introduced invasive species is that the invasive species is often very difficult to eradicate without serious disruption to the host ecosystem. An excellent example of an invasive species is presented by the zebra mussel, a small freshwater species of shellfish originally native to the freshwater lakes of southern ussia. The introduction of zebra mussels into the freshwater habitats of North America has allowed them to spread at astonishingly fast rates: the zebra mussel reproduces…… [Read More]

Case Study: Climate Change and Dealing with Sea Level Increase

Rising sea levels have emerged as one of the major concerns in today’s world because of the increased devastating impacts of climate change or global warming. While increase in sea levels is expected to affect the whole world, some regions will be affected more than others. One of the regions that will be significantly affected by sea level increase in China based on a recent report from Climate Central. China is among one of the major Asian countries that has experienced tremendous economic growth over the past few years. The country is characterized by faster-growing coastal megacities and a population of more than 145 million people. Actually, these coastal cities account for approximately 70% of China’s big cities and 41% of her population (Chen, p.925).

The city of St. John's can also borrow a leaf from the City of Ottawa's Greenbelt that was put in place to avoid urban sprawl and provide open space for future development of natural areas. According to Eggleston (1961), the Greenbelt currently covers forests, wetland, and fields used for recreation conservation, farming, research, and forestry. The greenbelt has a variety of wildlife that fall under the category of mammals, birds, insects, reptiles and amphibians. Wildlife is a source of revenue especially when tourists come to watch them. The revenue earned from such activities can be used in bettering service delivery to the city residents. This is an economic benefit that the authorities of the City of St. John's stand to benefit from if they put in place nature and wildlife reserves within the city's vicinity. The…… [Read More]

International Regulation of Tourism in Antarctica

International egulation of Tourism in Antarctica

Since the mid-1980s, Antarctica has been an increasingly popular tourist destination, despite the relative danger of visiting the largest, least explored -- and arguably least understood -- continent on earth. Beginning with the 1959 treaty establishing Antarctica as an international zone free of claims of sovereignty by nation's that had been instrumental in establishing research stations there, there has been almost constant negotiation about how to administer regulations pertaining to the preservation of life forms on the continent, what those regulations should be, and what sanctions should be applied and by whom.

To understand the depths of the negotiations, and the potential for discord, it is necessary to understand what the continent offer the 65% of global nations that are party to the 1959 and all subsequent treaties. To understand the possible future of Antarctica, it is necessary to outline treaty attempts to minimize…… [Read More]

The Leblanc alkali production processes were especially pernicious, but they followed along the lines of previous industrial processes. In other words, the first British environmental legislation was a response not so much to a qualitative change in industrial processes and their environmental impact but more to a quantitative increase in sources of pollution that had up to that point been (if only barely) tolerable.

Legislation Arising From Public Anger

At the center of the first British environmental legislation was the Leblanc process, an industrial process that produced of soda ash (which is chemically sodium carbonate) that came into use in the first decades of the 19th century. Named after its inventor, Nicolas Leblanc, it replaced an older process in which soda ash had been produced from wood ash. However, as the availability of wood ash declined (because of deforestation, a process that was occuring both in Great Britain and across…… [Read More]

Osmoregulation

Endocrines Osmoregulation

Osmoregulation is the process, by which the body adjusts to a change in an environment of different water volume and amount of solutes in a cells and body fluid of organisms including vertebrates. Vertebrates are animals, which have a backbone, and can be warm either blooded or cold blooded. The body of such organisms adjusts in order to maintain the body balance both inside and outside their bodies in mild and harsh environments ranging from seawater, fresh water, and terrestrial habitats to very hostile environments. Endocrine glands found in such organisms play a major role in constant and persistent regulation of body balance, which secretes hormones directly into the blood whenever the body witnesses any environmental change (Bentley 45).

Endocrine glands present in vertebrates play a major role in controlling the level of water and salt in vertebrate's bodies. Hormones produced in vertebrates play a major role…… [Read More]

Genomics and Implications for the Future

The Human Genome Project has completed its monumental mapping of the genetic sequence in human DNA, and the field of genomics is taking advantage of these initiatives and innovations in technology to pursue scientific inquiries that could not have been imagined just a few years ago. More importantly, perhaps, new applications are being discovered based on the growing body of scientific evidence being developed by this emerging science. To determine what genomics is and how it is being used today and may be used in the future, this paper provides an overview of the biochemistry involved in the study of genomics, followed by an analysis of current and future trends in this field. A summary of the research will be provided in the conclusion.

Structure of Animals

Two animal phyla that can be compared and contrasted are Nematoda and Annelida. Nematoda are roundworms. There are more than 15,000 known species, with scientists estimating there may be as many as half a million species yet to be discovered (Waggoner, 2009). Nematoda have a worm-like appearance outside and a simple internal body structure. The phylum Annelida includes earthworms and their relatives, leeches, and a large number of mostly marine worms known as polychaetes (Waggoner, 2006). Annelids are characterized by their segmented bodies. They also have bristles on their bodies. It is estimated there are approximately 9,000 species of annelids today.

The Animal Phylogenetic Tree ("Mastering Biology," 2012) is a useful visual learning aid that is helpful in demonstrating the similarities and differences between these two phyla.

Pacific Garbage patch, as it's often referred to, exists between the U.S. mainland and Hawaii. Many estimates put its size at over two times larger than the state of Texas (Zhang, Zhang, Feng, and Yang, 2010). Much of this waste is composed of plastic, styrofoam, and other materials containing harmful ingredients that do not break down very quickly. In fact, much of this material ends up in the food chain due to the way it breaks down and is absorbed by organisms in the ocean. This garbage patch has been steadily growing, the product of waste dumping and pollution from the U.S., China, India, and other countries on or near the Pacific im. There are currently many scientists trying to both understand the true impact of the patch as well as trying to come up with ways to remedy it and prevent it from growing.
