Captive Breeding of Marine Mammals: Challenges and Mitigating Measures

Introduction
The growing demand to sustain the current lifestyle of the human population puts an added strain to the natural resources of the world. The increase in the exploitation of tropical forests and marine communities leads to a series of habitat destruction thereby leaving thousands of species of both terrestrial and marine animal homeless (Soule et al., 1986). Since 1986, there are already about nineteen percent and nine percent of the world’s mammals and birds respectively that are bread by zoos as per the International Zoo Yearbook Census. Based on the International Species Inventory System, there are about ...

Introduction

Multiple researches suggest that dinosaurs are among the most successful groups of animals to have ever lived on earth. Their body physique and adaptability enhanced their survival thereby extending their life longevity. In the course of time, these species evolved into diverse shapes and sizes. As a result, the different types of evolved organisms embraced various modes of living. According to Xu (2006), nearly 150 years after the discovery of the first fossils of the dinosaur, this species was believed be a reptile. In fact, when Richard Owen found the first remains of this organism, the paleontologists used the ...

- Fitzroy River Turtle (R Leukops)
- The Biology
Fitzroy River Turtle, Rheodytes leukops is also called the white eyed river diver referring to its Latin name. Locally, it is sometimes called the “bum breathing turtle referring to its ability to utilize cloacal ventilating. This method of breathing improves its breath-holding capacity and enabling it to colonize riffle zones and take advantage of the associated greater densities of food resources during the wet season and early dry season. . “R. leukops was first described as a new genus and species in 1980 (Legler and Cann,1980) and most publications ...

The natural selection theory is also referred to as the Darwinian Theory and is found in his book the Origin of Species which was published for the first time in 1859 . The Darwinian Theory has always been considered controversial due to the lack of background material to offer inheritance. Darwin makes the theory based on his personal observations of the fauna and the flora. Darwin’s ideas tend to focus on the end product and not on the process that leads to the existence of the end product. The theory was first introduced by Darwin in the 1850’s ...

Amongst the biggest problems that are being recognized is the phenomenon of global warming. This is an alarming issue for the environmentalists as they believe that the sustainability, worse yet, the livability of the planet is at stake because of it. Because of the economic and industrial conditions of the planet, the climate of the earth is changing rapidly. The average temperatures that are being measured are increasing very quickly, and it is feared that in a short period of time, the temperature of the planet will rise higher than what is comfortable (Root).
The problem of rising temperatures ...

Literature review: Half the Sky by Nicholas D. Kristof and Sheryl WuDunn

The following is a topic by topic review of various challenges addressed by Nicholas and Sheryl in the book Half the Sky. The authors identify various forms of oppression and abuse those women in most developing countries experience. Pertinent issues addressed include sexual abuse, discrimination of women in essential things such as education, employment and happiness in life.

There is a dire need to end the sex slavery on women. This can be successful if the fundamental causative factors are explored and resolved. To begin with, sometimes, women are not literally forced into sex by the male species of gender. The ...

British Petroleum – Perspectives on Gulf of Mexico’s Oil Spill

Introduction

Industrial Ecology.
INFORMATIONAL ABSTRACT.
For various commodities to be produced, raw materials have to undergo various processes in their specific industries until the final output is produced. This process takes place in industries. Industries need to regulate their manufacturing processes so that they take part in maintenance of the environment since lately it has been noted that the key factor destroying our environment is the industries through the manufacturing process. The emissions from the production of these commodities by the chimneys of factories pollute the air by releasing dangerous gases into the atmosphere. These ...

Introduction

Zika virus also termed as ZIKV is a known to have gained worldwide attention, especially in the USA, South East Asia, and Australia. The Zika belongs to the Flaviviridae family which comes under the genus Flavivirus (Wikan & Smith. 2016). The Zika virus is spread though day time mosquitoes belonging to the Aedes family. Some of the most common mosquitoes to contain and spread Zika include A. aegypti and A. albopictus. The name of Zika originated in 1947 where it was first isolated from the Zika forest in Uganda. Based on evidence, the Zika virus was associated with varying viral ...

People hold different views on matters of contraception in relation to abortion and Marquis is no different. According to him, abortion is immoral since it deprives the fetus the benefits it ought to enjoy in the future as well as the art of appreciating its current position as a fetus. He excludes the abortions done with regards to special cases such as prior to implantation, if the life of the mother is threatened by the fetus and in cases of rape. He, however, does not view the use of contraception in relation to abortion as morally wrong even though ...

Introduction

There are numerous descriptions of drowning that are available and actually, all of them bear some weight. According to Lunette, G., et.al death by drowning is the consequence of a obstruction of respiration by impediment of mouth and nose by a liquid medium which is more often than not water (2004). Actually, there are many other drowning definitions wherein all have some accuracy. In regards to true drowning, there are relatively no considerable disagreements, since there is a general conduit, which involves the water inhalation, which could eventually pass through the alveolo-capillary membrane thus eventually reaching the general circulation ultimately. Characteristically, a difference ...

Megan Ybarra and Paul Greenough examines the politics of ecology management in different academic works. The two works have similarities and contradictions between them, with some of the arguments rhyming with the popular beliefs while others are contradictory. In the article titled Bio-Ironies of the Fractured Forest appearing on the Series called In Search of The Rain Forest, Mr Greenough examines different hypotheses on conservation and the relationship between the wildlife and human beings which he refers to as “bio-ironies”). The first bio-irony discussed is that the modern exercise of conservation banishes conventional inhabitants of the forest only to ...

Introduction

Phytoremediation is the process through which certain environmental problems are treated through plantations that reduce the impacts of the environmental problems on other species. Phytoremediation is advantageous because a person does not need to excavate the materials containing harmful substances, hence, makes it effective in preventing environmental degradation. In addition, the process is cost effective because plants are readily available and it is easy to metabolize the harmful molecules present. Today, there are heavy deposits of metallic substances on the ground because of the growing level of industrialization in major cities. As a result, environmentalists are heavily challenged to ...

In the process of wound healing, angiogenesis is also known as neovascularization. The process commences in lined with the proliferation of the fibroblast when the endothelial cells mover towards the wound site. Oxygen and other nutrients are required for the formation of epithelial cells and the activity of fibroblasts. In comparison to the fibroblast and epidermal mitigation, angiogenesis is crucial for other stages of wound healing. The process of angiogenesis is complex and occurs in the following stages:
Latent period: In this stage, vasodilation and premeabilisation are known to permit leukocyte extravasation during the haemostatic and inflammatory phase. Decontamination ...

How the hyperbaric oxygen regulating NADPH facilitates the vascular health

The hyperbaric oxygen and GT Rac1 always plays a very central role in the activation of the complex. The Rac1 regulates the actin cytoskeleton as it responds to the various signals. When the NADPH is stimulated either by mechanical factors or by the signaling of the molecules, the Rac1 dissociates from its inhibitor and it is consequently activated by the release of the GDP and the binding GTP which in turn exposes the isoprenyl moiety ( Seyfried, T. N. 2012). This therefore agglomerates the cytosolic components of the NADPH oxidase NOXA1 and NOXO1. The end process therefore results to the ...

Craig Arnold’s “The Singers” is a contemporary poem which addresses a very poignant topic, namely the destruction of the environment caused by human activities. The poet chooses to focus on a specific aspect of this broad topic, namely the rapid extinction of bird species which is accentuated by the destruction of their environment. The speaker laments the fact that many species of birds are on the verge of extinction, and expresses concern over the disappearance of creativity together with the death of the natural world. The speaker dramatizes this environmental problem by illustrating the loss that humans face ...

Abstract

Pinto bean is a popular plant in the United States and Mexico, so knowing how it grows is an important topic in the field of botany. One of the factors that influence plant growth is the soil condition in which the seeds are planted on. Based from the many studies conducted on pinto bean, as well as soil condition and plant growth, the amount of water in the soil is an important factor in the quality and production rate of the plant. Lack of water can negatively impact the growth of pinto bean, but some varieties of the plant ...

As far as equality goes, there are no rules by which a person can be judged to be inferior to another person. There are differences, but these differences do not constitute a valid basis for discrimination, which is often the case with racism and sexism. As Singer argues, equality is a moral ideal rather than an assertion of a fact. The principle of equality is based on the fact that there are no moral differences between living beings.
Singer exposes the way in which animals are being used in order to satisfy human taste in food by saying that ...

Is the process of Globalization harmless for the planet and it's population?

Overview
With the technological advancement in the contemporary world, the process of globalization has gained moment raising questions regarding its impact on the planet and its population. Globalization is political, economic, and social phenomena that explain on the increased integration of the global society, especially in the economic integration (Gangopadhyay and Chatterji, 2005, 57). Some studies show that although globalization is an essential process in the modern world, the process involved is controversial. According to Dauvergne (2005, 371), some scholars argue that the process is the source of ingenuity, progress, and cooperation of the future world and enhanced the ...

Charlotte’s Web by E.B. White, Hana’s Suitcase by K. Levine, Why Me? By L. Allen and The Paper Bag Princess by R. Munsch present a wide range of conflicts and themes that are aimed at teaching children something about the world that surrounds them. All of the books are under the great influence of the ideology of the times they were written, so it is easy to spot different attitudes towards the same question, as for example, the classic emotional and empathic women in Charlotte’s Web and strong and brave Elizabeth in The Paper Bag Princess. ...

Lehn defines the concept of Supramolecular chemistry as 'chemistry beyond the molecule'; chemistry of the intermolecular bond that includes the functions and structures of the entities resulting from the bonding between multiple chemical species. According to Vogtle and Alfter (1991), supramolecular chemistry, contrary to molecular chemistry, is based on intermolecular bonding or interactions, while the later is predominantly based on the covalent bonding of atoms. In other words, supramolecular chemistry deals with the bonding between two or more building blocks that are bound together by means of intermolecular bonds.
The aforesaid concept bears on the organized entities of ...

The theory of human evolution says that the humanity evolved from primates, or ape, as their ancestors. According to scientific research, all mammals evolved from protomorphic reptiles in the Triassic Period, about 200 - 245 million years ago. When the dinosaurs had undergone extinction during the terminal Cretaceous, the mammals remained as the surviving groups, adapted accordingly in the Tertiary Period. The majority of mammals evolved in this very period, including the Primates, relative to humans.
There are two hypotheses, concerning the origins and evolution of today’s humans, Homo sapiens, both based on the assumption that our ...

The issue of conservation has been dominating the agenda of environmentalists in the recent decades, and the two articles under consideration provide insights into adverse and side effects of forest conservation and establishment of biosphere reserves. Generally, Paul Greenough discusses advantages and flaws of biosphere reserves and protected area networks that have been a crucial purpose of conservationists. The author argues that enclosing new territories of forests into protected areas and reserves allows not only for survival of animal and plant species but also for blossoming criminal activity. Providing examples of Mexican biosphere reserves and India’s Project Tiger ...

How absentee fathers affect teen pregnancy in daughters

Introduction
The family is the basic unit of society. From this structure, individuals learn the tenets of how to integrate into society and cope with other members. Most mammal species live in the family unit, be it nuclear or extended. Within the family, members learn to bond, share and assist each other with difficulties. The human species shows the most sophisticated form of human organization. When children get born, they only get taught how to survive as adults, but there are certain values that parents must pass on to their children. Each family and society have different values and ...

Summary of Skinner and Piaget Articles

Summary of Skinner and Piaget Articles
B.F. Skinner
The article on Skinner discusses (2008) his theories about verbal behavior. He refutes other theories of language acquisition and verbal communications, making the case that all verbal communication is a behavioral response to environmental stimuli. Over time, a human being develops patterns from repeated responses to a similar stimulus and the result is a collection verbal behaviors that appear to characterize that individual’s personality (as cited in Diessner, 2008). But, says Skinner (2008), the verbal behavior is not driven by any internal personality or character of that person, only by ...

1. Historical evolution of Mumbai
Mumbai has a long history of evolution that spans for 1000 years. In 1343 the cluster of seven islands was controlled by the Sultanate of Gujarat, and later in 1534 following Portugal invasion, the area was converted into a trading center (The British Library Board). The Portuguese coined the term Bom Bahia, meaning ‘the good bay’, and developed dwelling units, factories as well as ship building yards in the Island cluster, which later became known as Bombay (The British Library Board). With the establishment of East India Company, the British ousted Portuguese, and used ...

Introduction

The fishing industry is a diverse industry that includes many activities and practices concerning fish and has been in existence for many decades. Nonetheless, the industry over the years has been faced with a wide range of issues with the most critical being environment issues. The environmental issues have thus resulted in the threat of aquatic life, particularly the fish family. The survival of lobsters particularly in Maines, New England in this regard has been forced to depend on water temperatures, the cleanliness of the of the habitat and the increasing concerns about the rising cases of the lobster ...

Mechanical ventilation (MV) causes oxidative stress that is responsible for adverse consequences on organs. In a situation of MV, the excessive pressure impairs the function of the mitochondrial respiratory chain leading to oxidative and nitrosative stress (Kavazis, 2009; Hafner et al., 2014). MV is commonly associated with hyperoxia where an excess of oxygen is provided. In such a case an oxidative stress can be induced when the oxygen pressure in the alveolar exceeds that of the normal breathing conditions because the biological system is not able to readily detoxify the environment from components such as reactive oxygen species (ROS) ( ...

) The text’s author suggests that Charles Darwin, author of the theory of evolution, actually possessed a romantic view of nature. If this so, what do the passages from The Origin of Species on page 212-3 tells us about what Charles Darwin (and Romantics in general) may have thought of nature.
Gloria Fiero indeed suggests that Charles Darwin had a romantic view of nature. Before he authored the revolutionary but controversial theory of evolution, he had been exploring South America to the Pacific Ocean for a research on fossil. In his voyage, he had an intimate eye on every ...

The population of deer in the Midwest is tremendously on the decline, a situation that raises efforts of conservation agencies in addressing the situation. The deer represent a class of wild animals that require maintaining their numbers in order to increase the reproductive ability of future generations. More specifically, the deer population in the United States of America in 2014 was 32.1million where 28.5million represented the numbers of whitetails, and only 3.6 million accounted for the black tails, mules and others (America's Department of Natural Resources: --the U.S. Department of the Interior 15). Notably, the numbers had dropped from 33.5 million ...

My impression of the novel is a book capable of inducing the feeling of eroticism, sexual energy, danger, and suspense all at the same time. In my view, the genre of the novel can best be described as an erotic thriller. The novel present a strange intermixing of humans and other supernatural beings. Indeed, the writer follows the modern tradition of presenting vampires as a romantic, erotic and elegant species rather than some demonic creature. The character of Sookie Stackhouse is indeed a very intricate one the more I read about her and the more I become familiar with her personality the more ...

Introduction

Bacteria are the very first life forms in the history of our planet. Since the beginning they were exposed to extreme changes of temperature, pressure, pH and nutrients; hence, to survive, they had to adapt themselves. One strategy of survival is to go into suspension or dormancy, by converting themselves into a seed form or spores. When conditions become normal, these spores germinate back to vegetative form. This property is also seen in pathogenic bacteria that infect higher animals such as humans. One such group of bacteria is from the Genus Bacillus.When exposed to stress, these bacteria go into dormancy ...

The Noah’s Flood is a play adopted from the biblical story of the manner with which God rescued a few of his followers from a terrible flood that wiped out the entire human race. In the beginning, God told Noah that he would have to put an end to all the people on the universe because their deeds were evil and violent. Noah was the only man of good faith in whom God had placed his trust because God believed that his ways were chaste. God asked him to build an ark and put his entire family in it. Besides that, ...

Introduction to MRSA

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial strain of S. aureus that that has developed a resistance to certain types of antibiotics, including methicillin, penicillin, oxacillin, and amoxicillin (Farley 2008). The types of infections differ according to whether the MRSA infection was acquired in the hospital setting (HA-MRSA) or whether it was a community acquired MRSA (CA-MRSA) infection. The most severe MRSA infections are those acquired in health care facilities and include infections of the bloodstream or surgical wounds, and pneumonia. MRSA bacteremia is often fatal, thus timely and aggressive intervention is critical in patients at high risk of death; for example, ...

Geospatial technology is a very important tool for monitoring and analyzing the effects of human activities on the environment.
