Genus species- Solenopsis invicta Buren
Common Name- Red imported fire ant (RIFA)
Invasion Status- S. invicta is on the “100 of the World’s Worst Invasive Species” list, which is compiled by the Invasive Species Specialist Group (ISSG 2010) of the Species Survival Commission of the International Union for Conservation of Nature (IUCN). A federal quarantine (Figure 1) has been placed on S. invicta for much of the southern United States being enforced by the Animal and Plant Health Inspection Service (APHIS) of the United States Department of Agriculture (APHIS 2013).
History of invasion-
S. invicta, is an invasive nuisance that was first introduced from South America in the 1930s (Morrison et al. 2004). It is thought that S.invicta was first

Updated estimates show the infestation now covers more than 128 million hectares in 13 states and Puerto Rico (Callcott 2002). As of 2001 S. invicta is also now established on the Caribbean Islands, New Zealand and Australia. Most recent infestations have been found in Taiwan and mainland China (Zeng et al. 2005).
Ecology and Natural History-
S. invicta has been shown to have two social forms, a monogyne and polygyne form. The monogyne system only contains one mating queen, while in the polygyne system there are multiple queens (Ross 1997). The two are distinguishable by genetic comparison of the Gp-9 locus. The polygene form is identifiable by all being heterozygotes (Bb) at the Gp-9 locus (Ross 1997). Both social forms have been shown to occur throughout the United States, although it is thought that the monogyne form is largely responsible for the initial invasion (Tschindel 1998). Mating flights are the common form of colony expansion and secondly budding can occur in which a portion of a colony becomes a self-sufficient unit. On average S. invicta will have six to eight mating flights a year occurring between the fall and
“Hemlock wooly adelgid was first discovered in the eastern United States in Richmond, Virginia in the 1950’s, likely originating from a population in southern Japan”, according to the text “Eastern Hemlock Conservation Plan.” The insect is also invasive because it damages the ecosystem. Hemlocks are a major part of some forest ecosystems and provide some unique benefits, but the Hemlock Wooly Adelgid is killing Hemlocks throughout
President Obama established a national marine memorial off the coast of New England. The new memorial, which is about the size of Connecticut, houses geological and ecological treasures. Under the surface of this protected ocean rest canyons and extinct volcanoes. Rare fish, coral, whales, and turtles count themselves among the animals that live in the memorial. Critics cite the possible harm the memorial will cause to the fishing industry.
In the story “Good Country People,” the author Flannery O’Connor talks about four main characters in this story. One is a young traveling Bible salesman named Manley Pointer. We will talk about the sales techniques he used to try and sale the bibles. One will find out how effective these methods are in getting what he wants. The other main characters are Joy, Mrs. Hopewell, and a nosy neighbor, Mrs. Freeman.
Originating and found from countries near the Mediterranean, the French Broom was brought to California, more specifically the Bay Area, as a decorative plant in the 1800’s. The plant grows rapidly, with thousands of seeds being produced every year, especially through the months of April and July. Seeds scatter more than 10 feet away from its plant, and animals scatter them away even farther. French Broom prevents native plants from growing and reproducing. For example, the article explains, “It is a strong competitor and can dominate a plant community, forming dense monospecific stands” (“Invasive Plants”). Eating the seeds has also been known to cause paralysis and digestive disorders in animals. The seeds can also survive in icy and chilly
As a hard-working, committed individual, I believe that being a member of National Honors Society will significantly benefit my personal character, academic achievements, and social life. After conducting some research on National Honors Society, I have come to learn that NHS needs students that exemplify the qualities of character, service, scholarship, and leadership to be qualified for membership. By being qualified for this outstanding opportunity, I believe that I can attain leadership skills, and confidence which can be beneficial in the years to come.
National Honors society would be an amazing opportunity for me. I believe I would be a perfect fit
Invasive species come in many forms; they can be plants, animals, insects, fish, fungus, organisms, and bacteria. Invasive plants are those which cause environmental, economic and human harm and originate from another area or region. They are a complex and difficult problem to tackle. There are more than 4,000 plants species found in Florida, of those 1300 or more are non-native or invasive. Many invasive species are taking over Florida’s waterways disrupting their natural ecosystem by outgrowing and replacing Florida’s native plants. Relieving the damage they cause is not easy, but scientists and members of the communities being affected are finding that it is achievable, as long as everyone works as a team to address the issue.
As the veterans are coming back into the society, they must be helped to connect to the community. For example, these veterans were secluded from the functional family unit (International Council of Nurses, 2008).

Another invasive species are the Nutria. The Nutria comes from South America. It is not exactly clear
Originating from eastern and southern United States, phylloxera lives on native American vines. Developing on mature storage roots, phylloxera disrupts their function, allowing countless secondary fungal pathogens to be introduced. Early signs of a phylloxera infestation include yellowing of leaves and stunting of growth as the leaves lose function. Symptoms will appear within three years, ultimately killing the vines between five to six years depending on the phylloxera genotype. Phylloxera is characterized by having three-jointed antennae, the third of which is the longest, and its overlapping wings resting flat on the back. It belongs to the order of Homoptera, and shares commonalities between two families of that sub-order: the plant-lice and bark-lice. Their lifecycle, from egg to adult, is gradual and complex—one species is known to progress through 21 different phases. Phylloxera adults are all female and reproduce asexually. One adult female is capable of producing 1) 200 eggs per cycle and 2) having several cycles in a lifetime.
The Department of Veterans Affairs is a government run system that provides benefits to all veterans of the United States military. Along with assisting veterans, it is also a benefit program for the families of the veterans. Many sections of the department are very obvious to those not involved, however there is much more to it than we see. There are three main sub sections of the program. These include the Veterans Health Administration (VHA), Veterans Benefits Association (VBA), and the National Cemetery Association (NCA). All this is possible due to the increase in funding over the past decade. The department has grown tremendously since its very beginning in 1636 to what it is today.
Nobody likes the up stuck rich guy whose pride always gets in the way of their very own safety. And that’s exactly who Fortunato and Hammond are, the up stuck rich guy. Both Fortunato and Hammond are weirdly similar, through the way they act, to their background of how they came to be. The obvious thing that makes these too similar is through their personality, they both are ignorant and lack the capacity to listen to others. The next way these two are similar is the way they act in situations, their pride always gets in the way of anything that they do and sometimes that gets in the way of their safety. And the last thing is their background, such as the money that they have. These two share a lot in common with their traits and their upbringings.
Lay your weary hands on me, Isosceles. Concealment swells. I hear the echoes from your cell. Crows guard your doorstep.
The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.
