...plants) prefer garden snails Introduction: The question is important because it deals with changes in the environment over short or long period of time. In other words, it deals with the preferable environment of food for garden snails. The answer to the question indicates the preferable plants that garden snails like to eat. Firstly, a few words will be said about garden snails, and then about the leaves that were given to the snails in this experiment. The independent variables are the types of leaves that are edible by human beings. (Chinese Broccoli ( Kai lan) , Beet root , English spinach, Bok Choy ( Chinese cabbage) and the control- Lettuce. ) The dependent variables are the quantity of leaves that the garden...

...Organism Physiology Paper BIO 101 10/27/2012 Hossam Ashour An organism that I had always found interesting to learn about is a snail. A snail, along with other organisms including clams, mussels, slugs, octopuses, squids and oysters are all in the same group of invertebrates called molluscs. There are two types of molluscs, land and marine molluscs. The purpose of this paper is to identify how molluscs evolve physiologically to become suited to its environment. Molluscs are soft-bodied animals, but most are protected by a hard shell (Dr. Anthoni, 2007). Some molluscs have internal shells that are internal that eventually fall off during the evolution process. One thing that seemed to intrigue me was how snails eat and survive. Snails, like many other molluscs have an organ call radula used to scoop up food. Snails use the radula to cut food into smaller pieces before eating it. In the diagram, the main organs shown are the heart, kidney, lung, genitals, stomach and the liver. One of three main parts of molluscs is the visceral mass which is where most of the internal organs are located. A snail falls under one of three major groups of a mollusc called gastropods. Most of these animals have a protected shell. A snail’s internal organs include the following: lung, digestive organs, a kidney, liver and reproductive organs which most were shown in the diagram of a mollusc. It can be very dangerous for a snail in terms of surviving and evolving. Due to their small size and...

...Why are cigarette butts littered? In the article, Whose butt is it? Tobacco industry research about smokers and cigarette butt waste, the psychology of a smoker littering the butt of a cigarette was research looked at. There had been previously done focus groups by the tobacco industry about this subject because the industry had realized that the litter was bad for business. What they found was that people littered because it was so common place that they found it to be almost acceptable. Some people in the study even said that putting a cigarette out on the ground was “conscientious” because it “eliminated the risk of fires.” Others didn’t believe or acknowledge that there was an environmental concern in tossing the butt on sidewalks or...

...Introduction Do organisms undergo a long and gradual processes of evolution, or do they exist for long periods of stasis – minimal change – and abruptly evolve into a different form? These two questions surround the debate of whether evolution occurs by phyletic gradualism, or by punctuated equilibrium, respectively. This paper will present both hypotheses and reasons for their prevalence, then it will argue one hypothesis with current research on the topic, finishing with suggestions for further research and direction. Hypotheses The hypothesis of gradual change is termed Phyletic Gradualism, and it describes evolution to happen as a slow and gradual process, whereby a large ancestral population transforms into a distinct descendent (Eldredge...

Box 751403, Fairbanks, AK 99775; and **Department of Biology and River Studies Center, University of Wisconsin, 1725 State Street, La Crosse, WI 54601 Contributed by Stephen R. Carpenter, August 16, 2007 (sent for review June 18, 2007) The widespread emergence of human and wildlife diseases has challenged ecologists to understand how large-scale agents of environmental change affect host–pathogen interactions. Accelerated eutrophication of aquatic ecosystems owing to nitrogen and phosphorus enrichment is a pervasive form of environmental change that has been implicated in the emergence of diseases through direct and indirect pathways. We provide experimental evidence linking eutrophication and disease in a multihost parasite system. The trematode parasite Ribeiroia ondatrae sequentially infects birds, snails, and amphibian larvae, frequently causing severe limb deformities and mortality. Eutrophication has been implicated in the emergence of this parasite, but definitive evidence, as well as a mechanistic understanding, have been lacking until now. We show that the effects of eutrophication cascade through the parasite life cycle to promote algal production, the density of snail hosts,...

...organisms due to interspecific competition, Introduction: California mussels (Mytilus californianus) are abundant where there is surf along the outer coast. They form massive beds, sometimes several meters across, on surf exposed rocks and wharf pilings in the upper middle intertidal zone and offshore, up to 24 meters deep. Like barnacles, mussels like to gather in dense clusters in the middle intertidal zone. Mussel beds are often large enough to be a home to many other creatures, like snails and worms. California mussel beds accumulate a gritty mixture of sand and bits of shell which provide a home for a various assemblage of animals including a number of polychaete worms, snails, crabs and a blackish sea cucumber. The Ochre sea stars are California mussels' main predator. Ochre sea stars affect the distribution of the mussels because the sea star generally occurs lower on the shore than the mussels and moves up to feed during high tide. Mussels are also eaten by shorebirds, crabs and snails. When a predator eats the dominant species, then predation may prevent the dominant species from monopolizing a limited resource, thereby increasing diversity of species in that area. Mortality in intertidal open coastal environments is often high, resulting from battering driftwood and other debris, wave pounding, predation, desiccation, and disease....

...The Galapagos Islands Axia College of University of Phoenix May 6th, 2009 For the purpose of this paper I will attempt to provide interesting information on the birds, plants and snails of the Galapagos Islands. I will discuss the biological interrelations between the species to include how they are affected by the human intrusion. I will also share some information on the conservation groups that are trying to preserve these islands for the future. The Galapagos Islands are located in the eastern Pacific Ocean approximately 600 miles off the west coast of South America. The Galapagos Archipelago consists of 4,897 square miles of land over 28,000 square miles. There are 16 islands that provide tourists and visitors with many spectacular species to look at. These species are comprised of birds, marine life, tortoises, sea lions, iguanas, snails and flora such as cactus and mangroves. (Galapagos Online, 2009) The Galapagos Islands are home to many species of birds. Some of these birds are the Blue-Footed, Red-Footed, and Masked boobies; Darwin’s Finches which are comprised of 13 different species belonging to 4 genera; the Albatross and the Galapagos Penguins. (Galapagos Online, 2009) The three varieties of boobies are different in nature. The Blue-Footed Booby’s natural habitat extends from Peru to Mexico. They nest in colonies. They can be seen breeding on most islands north of the equator. (Galapagos Online...

...added expenses not to mention the bad effects of these chemicals to health and environment. Dr. Alfredo R. Rabena, head of the Research and Development Office of the University of Northern Philippines in Vigan City, Ilocos, has discovered a solution. He found that the leaves of kakawate tree or Mexican Lilac (Glinicidia sepium) contains coumarins, an effective botanopesticide. To prepare the solution, chop the kakawate leaves and let these soak overnight to extract coumarins. Using a strainer, separate the leaves from the solution. Spray the solution to the ricefields. The best time to apply it is from eight o’ clock to nine o’clock in the morning and from five o’clock to six o’clock in the afternoon as worms and pests are coming out from the leaves at these times. So the solution would be more effective to use. If applied early, it wouldn’t be that effective as pests are still hibernating. And if used when the sun’s heat is too hot, it wouldn’t be that effective also as pest would hide. Since kakawate is a legume, says Rabena, its leaves are rich in nitrogen, an important soil nutrient. Hence, the discarded leaves can be applied to the field as an organic fertilizer. He also recommends fanners to put several leafy branches of kakawate tree in between rice plants two days after planting to prevent pests from attacking the crop. To prove this research finding, Rabena and Flora Cely Rodilias did a demonstration in Naglaoa-an, Sto. Domingo, Ilocus Sur as well as in Vigan City and...

...review of a scientific journal article. Both types of writing ask you first to read and understand an article from the primary literature about your topic. The summary involves briefly but accurately stating the key points of the article for a reader who has not read the original article. The critique begins by summarizing the article and then analyzes and evaluates the author’s research. Summaries and critiques help you learn to synthesize information from different sources and are usually limited to two pages maximum. Actions to Take 1. Skim the article without taking notes: Read the abstract. The abstract will tell you the major findings of the article and why they matter. Read first for the “big picture.” Note any terms or techniques you need to define. Jot down any questions or parts you don’t understand. If you are unfamiliar with any of the key concepts in the article, look them up in a textbook. 2. Re-read the article more carefully: Pay close attention to the “Materials and Methods” (please note that in some journals this section is at the very end of the paper) and “Results” sections. Ask yourself questions about the study, such as: o Was the study repeated? o What was the sample size? Is this representative of the larger population? o What variables were held constant? Was there a control? o What factors might affect the outcome? 3. Read the “Materials and Methods” and “Results” sections multiple times: Carefully examine the graphs...

...Biotic Component Paper Biotic Components Paper In this paper I will conduct research on the Bolsa Chica Wetlands that are located in an area of lowlands in Orange County California, adjacent to the city of Huntington Beach. The area is managed by the National Marine Fisheries Service (NMFS), whose mission is to” protect and enhance; migratory shorebird, seabird, waterfowl overwintering habitat; protect natural habitat for shorebirds and seabirds; protect nesting and foraging conditions for threatened or endangered species” The Bolsa Chica Conservancy (BCC) is a local volunteer organization that assists in maintaining the area. Its goals are to ensure the preservation, restoration, and enhancement of the area (2010). This dynamic, yet fragile, ecosystem has been preserved since 1965, flourishing under diligent and careful management. Coastal ecosystems include marshes, coastal waters, estuaries, and lands located at the lower end of drainage basins, where rivers and streams meet the sea or ocean (United States FWS, 2010). These complex ecosystems are composed of biotic communities; plants, animals, birds, and microbes, and the abiotic community; nonliving, chemical, and physical. According to Wright (2008) the type of biotic community found in a given area, is largely determined by the abiotic factors, such as the amount of water, climate, the salinity, or type of soil. Bolsa Chica has a wealth of plant and animal species including Sea Lettuce, Pickleweed...

...Young1 RICHARD BALLARD PROFILE By definition, Richard Ballard was a great oceanographer. Ballard had always been interested in the sea since he was a little child. His curiosity got the best of him and he has accomplished so much since then. He has written a variety of books to go along with his scientific research and findings within the ocean floors. One of his most popular discoveries was The Titanic. His underwater archaeology work is amazing. It is pretty impressive to know that Ballard has a sense of humor when it comes to storytelling in his books. It is pretty incredible to go submarine diving and not know if you will surface because you are on a mission to find the impossible artifacts within the black sea. Ballard was also known for his natural discoveries during his deep-sea expeditions. Even though Ballard is known for his discoveries, his first expedition was unsuccessful. There are many written pages that discuss Richard Ballard’s underwater discoveries. “During Richards long career he conducted more than one hundred-twenty deep-sea expeditions using the latest in exploration technology, and he is a pioneer in the early use of deep-diving submarines” (Richard Ballard). As the president of an Exploration Institute, Ballard received many prestigious awards for his discoveries, television appearances and books to go and prove his findings. Many of Richards’s expeditions are well known. “He led the 1977 expedition that discovered deep-sea hydrothermal vents...

...Running head: ORGANIZATIONAL CHANGE PROPOSAL Change Initiative Paper In today’s business organizations need to be prepared to make changes. Be it planned or unplanned change is one constant in business as we know it. An organizations ability to adapt or handle the change will determine that organizations success. Some changes are very large scale and some are not. This paper will examine a change proposal and action plan to make the change an overall success and smooth transition. Guidelines for change are a necessary part of a successful change process. Planned change is a set of activities in an organization that are intentional and goal-oriented (Nameer, 2008). Proposed Change Brownstone Square is an owner run Homeowners Association in Phoenix, AZ. The association manages paperwork for sales, the grounds, owner complaints, and accounts receivables and payables. Owners make a monthly payment of $125.00 to the association for the services provided to them as outlined in the associations’ contracts with each of them when they joined the community. Overall the association provides services as promised in a timely manner consistently. The homeowners on the other hand do not always make their monthly payments on time, consistently. The association faces the problem of missed payments and homeowners who are frustrated with the very antiquated system of having to “snail mail” a monthly check to the association. Homeowners have approached the elected...
