...Vanessa virginiensis The Monarch Butterfly, or Vanessa virginiensis, is a large orange or black butterfly that is most known for its distinctive multi-generational migration from Canada to Mexico and vice versa. Many conservation societies are beginning to raise awareness about the conservation and safe use of herbicides that have affected the Monarch over the last few years, after a ten-fold decrease in the population. The Monarch can be found in the entirety of the Continental United States, as well as Canada and Mexico, depending on the season. As well as being found in the United States, a common attractant of the butterfly is a plant called milkweed, which is often a host plant in which the Monarchs’ eggs are laid. Monarchs have many...

Monarch Butterfly Migration [ http://www.gettyimages.com/detail/photo/monarch-butterflies-flying-during-a-warm-high-res-stock-photography/102334428 ] [http://www.dreamstime.com/photos-images/monarch-butterflies.html#details51435102 ] Monarch butterflies migrate in spectacular flocks of color in various U.S. and Canadian locations during the fall when the butterflies return to a warmer climate in Mexico. These flocks travel thousands of miles, but no single butterfly survives the trip. Female monarchs lay eggs during the migration, and their offspring continue the journey. These amazing insects use their antenna to tell them when the sun rises and sets and automatically process the information internally to keep them geospatially on course. The butterflies cover between 25 and 30 miles per day, lay hundreds of eggs each and continue on their way. The children and grandchildren continue the journey. 8.

...Background Monarch butterflies can get unlimited frequent flyer miles since they can fly about 250 miles a day. Monarch butterflies, which translates to “king of butterflies,” are native North American butterflies. They are classified into eleven different species, three of which are found in North America, whereas the rest spread across the world throughout the Caribbean, the Pacific region, South America, Eastern Africa, Southeast Asia, and Central America (“Monarch Systematics”). In addition, the largest population of monarch butterflies reside in North America, Central America and Australia, although monarchs are still sighted in Southwest Europe and the Hawaiian Islands. Danaus plexippus is the species of monarch butterflies found in North America (“Global Distribution”)....

...IS THE MONARCH HEADING FOR EXTINCTION? 1 The Monarch Butterfly: Is extinction in the near future for the Monarch? Samuel O. Dean Western Governors University WGU Student ID# XXXXXXXXX IS THE MONARCH HEADING FOR EXTINCTION? 2 Is the Monarch Heading for Extinction? The monarch butterfly is well known and easily recognized, as it inhabits many islands and continents of the world (Bradley & Altizer, 2005). Most of the monarch populations are solitary; they remain in one basic geographical area throughout the year. The eastern North American monarch butterfly is a unique variant because it undertakes an incredible migration, spanning thousands of miles, crossing through three countries and requires three to four generations to complete this cycle every year. Throughout this journey, the monarchs breed, lay their eggs and die; it is their offspring which complete the journey. Starting in central Mexico in early spring, the monarchs traverse northward throughout a majority of the eastern United States and into southern Canada before returning to their overwintering grounds in the Transvolcanic Belt of central Mexico before winter sets in (Rudolf, Ely, Schaefer, Williamson, & Thill, 2006; Yoon, 1998; Williams, Stow, & Brower, 2007; Williams & Brower, 2007). Over one billion butterflies migrate southward from their one million square mile breeding range, forming densely packed colonies of up to 50 million butterflies per hectare while they...

...Genetically Modified Foods fall into three categories: environmental hazards, human health risks, and economic concerns, which brings me to my first contention. Contention 1: Environmental Hazards. In 2012 a lab study was published in nature showing that pollen from B.t. corn caused high mortality rates in monarch butterfly caterpillars. Monarch caterpillars consume milkweed plants, not corn, but the fear is that if pollen from B.t. corn is blown by the wind onto milkweed plants in neighboring fields, the caterpillars could eat the pollen and die. Even though the Nature study was not conducted under natural field conditions, the results seemed to support this viewpoint. Unfortunately, B.t. toxins kill many species of insect larvae indiscriminately; it is not possible to design a B.t. toxin that would only kill cropdamaging pests and remain harmless to all other insects. This study is being reexamined by the USDA, the U.S. Environmental Protection Agency (EPA) and other nongovernment research groups, and preliminary data from new studies suggests that the original study may have been wrong in some ways. This topic is the subject...

The other ideology that is pitted against that of Byron’s is that of the Feathertown populace which is an overtly religious town where most things are attributed to God’s plans or in the case of Dellarobia Turnbow finding the butterflies as “‘a miracle’” (Kingsolver 54).

...Overview Printable Version (PDF) Tell a Friend Genetically-modified foods (GM foods) have made a big splash in the news lately. European environmental organizations and public interest groups have been actively protesting against GM foods for months, and recent controversial studies about the effects of genetically-modified corn pollen on monarch butterfly caterpillars1, 2 have brought the issue of genetic engineering to the forefront of the public consciousness in the U.S. In response to the upswelling of public concern, the U.S. Food and Drug Administration (FDA) held three open meetings in Chicago, Washington, D.C., and Oakland, California to solicit public opinions and begin the process of establishing a new regulatory procedure for government approval of GM foods3. I attended the FDA meeting held in November 1999 in Washington, D.C., and here I will attempt to summarize the issues involved and explain the U.S. government's present role in regulating GM food. What are genetically-modified foods? The term GM foods or GMOs (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methods can...

...Genetically Modified Food. The way to go? Name Institution Genetically Modified Foods also known as Biotech Foods are derived from genetically modified organisms (GMOs). They differ from traditional foods in that their DNA have been introduced to genetic engineering techniques to enhance desired traits such as improved nutritional content and much more. Over 40 plant varieties have federal requirements for commercialization as GMOs. It all started in 1946, when scientists discovered DNA transfer between organisms. The first genetically modified plant was produced in 1983 and now 165 million acres annually are grown. However, along with rapid adoption of technology have come myths propagated by proponents and opponents. Different GM organisms include different genes inserted in different ways. All GM foods currently available on the international market have passed risk assessments and are not likely to present risks for human health. The general population has showed no effects on human health because of the consumption of such foods. Continuous use of risk assessments based on the Codex principles and, where appropriate, including post market monitoring, should form the basis for evaluating the safety of GM foods. (Winter & Gallegos, 2006) The GM foods controversy is a dispute over the relative advantages and disadvantages of food derived from GMOs, GM crops used and other uses of GMOs in food production. The world population has topped 6 billion people and is predicted...

...Agriculture and Food Technology AENG 26 Introduction to Environmental Science Term Paper Effects of Genetically Modified Food on Human Amoguis, Jenina R. ECE 3 – 1 Engr. David L. Cero Professor Introduction Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield, through the introduction of resistance to plant diseases or of increased tolerance of herbicides. In the future, genetic modification could be aimed at altering the nutrient content of food, reducing its allergenic potential, or improving the efficiency of food production systems. The main purpose of genetic modification of food is to improve its taste, output, and make plants disease resistant. Despite these advantages, many people refuse to eat genetically modified foods over concerns that it could be dangerous to their health. However, there is still no detailed study about the long term effects of eating genetically modified foods. Genetically modified foods have more research challenges but also there are misgivings about its implications in the long run. All these...

...and a reduction in food cost. However, the green movement believe GM is a risk to public health, safety and environment. Firstly, they believe genetically modified foods will cause gene disruption and modification of existing genes causing toxicity; secondly, they will cause an increase in antibiotic resistance due to gene splicing and thirdly, genes will escape into wild populations (Jerome et al., 2010; Thies & Devare, 2007). The green movement uses an array of highly criticised scientific studies focussing on non-target species under very unrealistic circumstances to uphold the anti-GM argument (Trewavas & Leaver, 2001). A study by Losey et al., (1999) indicating harmful effects of genetically modified Bt cotton in Monarch Butterflies, was used by the green peace protesters at an EU council...

...It is toxic to bees and causes colony collapse disorder among them. Colony collapse disorder is when workers bees suddenly disappear from their bee colony. It causes adult bees to be absent with dead little bees. This is caused by honeybee enterprises feeding their bees high fructose corn syrup. For instance, a research project was conducted where there are five hives and four of them would be fed high fructose corn syrup with pesticides in them and the fifth would be fed just high fructose corn syrup (Helman 3). At first, nothing seemed to happen but as the experiment continued and a large mass of bees were seen fleeing from their hives. After several weeks, 15 of the 16 hives the researchers had fed the pesticide had colony collapse disorder showing that high fructose corn syrup, although not a direct cause of it, still causes the bees to become weaker and more vulnerable to pesticides (Helman...

...http://cls.casa.colostate.edu/transgeniccrops/what.html What Are Transgenic Plants? A transgenic crop plant contains a gene or genes which have been artificially inserted instead of the plant acquiring them through pollination. The inserted gene sequence (known as the transgene) may come from another unrelated plant, or from a completely different species: transgenic Bt corn, for example, which produces its own insecticide, contains a gene from a bacterium. Plants containing transgenes are often called genetically modified or GM crops, although in reality all crops have been genetically modified from their original wild state by domestication, selection and controlled breeding over long periods of time. On this web site we will use the term transgenic to describe a crop plant which has transgenes inserted. Image:Results of insect infestation on Bt (right) and non-Bt (left) cotton bolls. Source: USDA | Why Make Transgenic Crop Plants? A plant breeder tries to assemble a combination of genes in a crop plant which will make it as useful and productive as possible. Depending on where and for what purpose the plant is grown, desirable genes may provide features such as higher yield or improved quality, pest or disease resistance, or tolerance to heat, cold and drought. Combining the best genes in one plant is a long and difficult process, especially as traditional plant breeding has been limited to artificially crossing plants within the same species or with closely related...
