The Yellow Starthistle Plant

580 Words2 Pages

In California, the yellow starthistle invades 10 to 15 million acres of land (DiTomaso). This plant species is harmful to native plants and animals. Also, it has no beneficial purpose to the earth. Yellow starthistle is a problem in our world and it can be solved by extracting their roots from the ground and preventing the spread of their seeds (DiTomaso).
The yellow starthistle, also known as Centaurea solstitialis, is a plant that grows annually, has deep taproots, and can grow to be 1-3 feet tall (“Threat to Birds”). It harms native plants and animals. The yellow starthistle affects many native grazing animals because the spines can injure them if they come in contact with them (“Yellow Star Thistle”). Although it can harm other animals, this invasive plant is most harmful to horses because it is poisonous to them and causes them to develop a nervous disorder also known as “chewing disease” (DiTomaso). According to the California Invasive Plants Council, “This disease is expressed as a twitching of the lips, tongue flicking, and involuntary chewing. Permanent brain damage is pos...

    In Purple Hibiscus written by Chimamanda Adichie, the story of Kambili and her experiences throughout Nsukka and Enugu fit with the Hero’s Journey, a model of narrative that describes “the hero,” an archetype that ultimately reaches a great achievement through the stages of the Hero’s Journey. Although played in a realistic setting, unlike many of the examples portrayed in magical worlds such as Harry Potter and The Lord of the Rings, Kambili experiences the same stages of the journey and by definition, is considered a hero. The stages that contribute the most significantly to modeling the Hero’s Journey of Kambili is The Ordinary World, Crossing the Threshold, and The Ordeal.

  • Invasive Species: Eurasian Milfoil

    970 Words  | 2 Pages

    Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.

    Global change is taking place every day; therefore, it is important to understand how human activities and behavior alters the biodiversity and functions of ecosystems. Alien species is a stimulator of major changes in ecosystems (Vila et al. 2011). An invasive species, is a non-native plant, animal, or fungus that moves to a new ecosystem in a foreign environment. Invasive ecology explores how the invasive species affect the economic, environmental, and human health on the new environment. For example, invasive ecology studies how an invasive species tends to crowd out and sometimes replace a native species (Richardson and Pysek 2008).

  • Lantana Mites

    In 1843, lantana, a noxious weed from Central America, made its way to Australia as an ornamental shrub. Lantana rapidly infested approximately 4 million hectares. Recently new bio control ideas have come to light, such as using Eriophyoidea, which is a mite. Many mite species are virulent parasites. Seven species of Eriophyoidea are known to associate with the lantana, such as Calacarus lantanae Boczek and Chandrapatya, Diptilomiopus camarae Mohanasundaram, Eriophyes lantanae, Paraphytoptus magdalenae Craemer, Phyllocoptes lantanae Abou-Awad and El-Banhawy, Rhynacus kraussi Keifer, and Shevtchenkella stefneseri Craemer. There are many other types of mites that have been known to attack different linages of lantana. If mites were released into

    All discussions regarding the phenomenon of invasive species will inherently result in the consensus that they are an unwanted or an even evil entity. Ever since the age of exploration humans have been primary dispersers of these so called “exotic” species (Mooney and Cleland 2001). Famous examples include the release of cane toads in Australia (Urban et al., 2008); the rainbow trout (Fausch 2008) and the Japanese Kudzu vine in the southern U.S. (Blaustein 2001) and zebra mussels in the great lakes of Canada (Nalepa and Schloesser 1992).

  • The Yellow Wallpaper and The Chrysanthemums

    1015 Words  | 3 Pages

    Restraints are set by parents on their children to aid with the developmental process and help with the maturity level. Restrictions and the ability to control exist in our society and our lives. We encounter restraints daily: job, doors, people, and the most frequently used and arduous become intangible. In the following stories tangible and intangible scenarios are presented. Autonomy, desires, and talents spurned by the husbands in John Steinbeck’s “The Chrysanthemums and Charlotte Gilman’s “The Yellow Wallpaper.” The authors share views regarding a similar theme of male domination and imprisonment. “The Yellow Wallpaper” involves the treatment of a depressed woman who is driven insane in a male imposed detention in her own room. On the other hand, Elisa Allen in the “The Chrysanthemums” struggles internally to find her place in a fully male dominated society with definite gender roles. The mirror-like situations bring upon a different reaction for both the women in different ways. The importance of symbolism, control from their husbands, and the lack of a healthy marriage will be discussed in this paper in two stories.

  • Persuasive Essay On Invasive Species

    922 Words  | 2 Pages

    When people think of invasive species, they normally do not think of the human species, but why not? There is a large debate about whether or not humans are an invasive species. Before people debate whether or not the human race is an invasive species, they should know the definition of one. The legal definition of an invasive species in the United States is “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health” (Zielinski). The International Union for Conservation of Nature, IUCN, defines an invasive species as “animals, plants or other organisms introduced by man into places outside their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski).

    Invasive alien species are disrupting and changing the normal ecological functions of biomes, ecosystems, and the biosphere as a whole (CBD, 2009). They are a threat to biodiversity and can cause damage to, or even eradicate native species which natural cycles and other organisms depend on. While disrupting energy flow, food chains, and shaking the structure of ecosystems to the core, invasive species create not only ecological, but also a whole host of social, economical, and health issues that affect the livelihood of almost every organism on earth, including humans (CBD, 2009).

  • The Genus Datura: From Research Subject to Powerful Hallucinogen

    3682 Words  | 8 Pages

    Common names for Datura are numerous, some of the most common ones being raving nightshade, thorn apple, stinkweed, Devil's apple, Jimson weed, and angel's trumpet (Heiser 1969:140 and Avery 1959:19). Datura can be found throughout Asia, Europe, and the Americas as either native or adventive plants, and some have also been found in Africa and Australia (Conklin 1976:5). The epicenter of diversity of this plant is in the New World, specifically in Andean South America and in the southwestern United States/Mexico region (Lewis 1977:423-4). This data correlates with the generally agreed upon origin of Datura, although this topic was debated for some time. Researchers now believe the plant originated and evolved in Mexico and the American Southwest, followed by adaptive radiation into new desert environments (Conklin 1976:5).
