Plant pathogens and diseases

Marys Peak - Fir Forests Lindsay Liddell FES 342 Professor Matthew Powers MWF 10-11am Due: 10/19/15 Marys Peak is a mountain in Benton County, Oregon. At the top of the peak, on a clear day, one can see the cities of the Willamette Valley, the Cascade Range, and the Pacific Ocean. It is known for its meadows of wildflowers in spring and its fir forests uniquely populated with noble firs (Abies procera). Little data is available regarding the trees age, but there is clear variance in age,…

fortification or supplementation (Lipton, 2007). In countries like Uganda where 54% of children are vitamin A deficient (Anon, 2003), GM crops could be existential in lowering the related health risks such as greater vulnerability to infections and diseases, mental and physical impairment, blindness and premature death (González et al, 2009). Taking all these arguments into account, genetic modification seems to be the answer to ‘solving’ poverty in the Global South. An increase in the…

words nutrient and nourish are both derived from the Latin word nūtrīre which means ‘to feed, nurse, support and preserve.’ In other words, it’s really important to nourish your body with the right nutrients to support and preserve your health. While plants get their nutrients from the soil, we get ours from the foods we eat. Yet many of us don’t consider whether or not the foods we put into our bodies are full of healthful nutrients or not. We’re more concerned with taste and if we can…

The aspect of “global change” has become a very recognizable issue. People all over the world have become aware of the many issues contributing to the planet’s decline and unsustainable future. These environmental changes are continuously being researched and addressed, but no one really understands the extreme effects of this global change. The most vulnerable concept is the change in climate. The ATEAM project conducted by M.J. Metzger, M.D.A. Rounsevell, L. Acosta-Michlik, R. Leemans and D.…

majority of the time it is from the food they previously have eaten. In the article, “Foodborne Germs and Illnesses”, it states that, “Each year, 1 in 6 Americans gets sick by consuming contaminated foods or beverages. Many different disease-causing microbes, or pathogens, can contaminate foods, so there are many different food borne infections.” This ratio is high in showing how the foods we eat are not all safe and clearly inspected thoroughly. Many people are not aware of the food origins…

Food Production In the United States On average an adult in the United States will eat about 1,825 lbs. of food each year. To provide food to over 300 million consumers, a lot of procedures must be conducted and followed. This demand has altered the ways of food production. “The average meal has ingredients that have traveled 1,500 miles to our table” (Smith 2). All these ingredients came from a farm. Mass producing food has made local farmers disappear. This disappearance has caused food more…

European ecological imperialism began with the “decimation and demoralization of the aboriginal populations of Canada, the United States, Argentina and others.” (Crosby 106) This radical takeover by germs, weeds, domesticated animals, varmints, pathogens, “all accomplished demographic takeovers of their own in the temperate well-watered regions of North and South America.” (Crosby 116) As one Maori said, “As the clover killed off the fern, and the European dog the Maori dog – as the Maori rat…

workers about HIV became available, it was undecided how this virus truly spread. As health care providers, we were not sure if the virus transmitted via saliva, urine, fecal matter or blood. Because of our obliviousness related to these unambiguous pathogens, the health care community started to transform PPE policies and procedures instantaneously. Virtually overnight in the early 1980’s, our low-cost porous latex gloves were exchanged with a more expensive nonporous Nitrile composite style…

Alagoz Abstract The purpose of this paper is to explain propionibacterium acne’s structural properties, to make its microbiological analysis, to mention where it can be found, especially on human body, its photosensitivity and to describe the diseases and some infections it can lead to under specific conditions. Introduction Propionibacterium acnes (P. acnes) is a bacteria that grows deep inside of pores, which is relatively slow-growing, typically aerotolerant anaerobic and gram positive…

This paper explores the reasons behind the functional extinction of the Eastern Oyster in the New York Harbor, the ecological services that the oyster provided to the Harbor’s ecosystem and the steps to bring back this keystone species. When Europeans first came to the New World, oysters were so abundant around New York City that it was considered the Oyster Capital of the World (Driscoll, 2011) but within 300 years this title would be no more as the oyster became functionally extinct due to…
