The impact of invasive alien species
Title: The Asian tiger mosquito’s effect on both the environment and human health
The purpose of this research is to better understand invasive alien species, the main reason beyond their successful invasion in a non-native environment and also investigate their impact on the ecosystem. This research will have a close focus on the Asian tiger mosquito understand factors that have contributed to their spread globally and how they are affecting both the environment and human health.
Alien species are plants, animals, pathogens and others organisms that are living outside their native distributional range. The movement of these species is always the results of a human activity either deliberately or accidentally.

The female mosquitos have a very broad host range and can attack humans, amphibians, reptiles and births (Eritja et al. 2005). It was recorded in one survey of biting rates a level of 30 to 48 bites per hour (Cancrini et al. 2003). Ae. albopictus has the potential to carry and transmit a wide range of viruses; in laboratory it is proven that is capable to transmit seven alphaviruses, (e.g. Eastern Equine encephalitis and Ross River viruses) and it has been also proven in the laboratory that Ae. Albopictusis has the ability to carry and transmit eight bunyaviruses (e.g., Lacrosse and Rift Valley fever viruses), furthermore the species has the potential to develop three flaviviruses, (i.e. Japanese encephalitis, West Nile, and yellow fever) to human (Mitchell 1995, Shroyer 1986). All these viruses are very harmful to human and other organisms, they causes several diseases to humans. For instance in 2007 there was an outbreak of chikungunya in Italy, and other cases of dengue viruses were reported in south France and Croatia. The dengue virus is known to have four strains, therefore attacking one strain doesn’t immunize against contracting the other strains, so it become so difficult to treat the diseases caused by this virus. Chikungunya virus causes fever, swelling and redness of joints, severe rheumatic pains and in some cases death; according to research in various lab it has been shown that when a person is repeatedly infected with dengue viruses, this increases the risk of more severe sickness such as DenguhocyndromSS which induces shock as a result of a sharp drop in the volume of blood which might also lead to
Although they may be small in size, they have had a significant impact on human activities in terms of agricultural production and in the same way it can be observed that human activities have impacted this species in terms of optimal conditions for reproduction and growth. Globally, invasive insects cost an estimated $2. 1 billion in forest damage and $13 billion in loss of crop depending on how detrimental the species is but nonetheless, a species such as the love bug demonstrates that even nuisances can provides benefits amide the costly
There are many invasive species that are affecting the Everglades by invading the ecosystem. Many of these species were brought to the everglades by people and animals. They are changing the ecosystem and are competing with natural native inhabitants of that area. The native species have to adapt to the change or move to another area to survive. Both plant and animal species have invaded the area within the Everglades.
Mosquitos soon became resistant and the only approach was to use more chemical sprays. Deaths of many birds were due to bio magnification caused by the extraneous amounts of toxins in water. Suzuki acknowledges how his faith on “predictive
One of the biggest summer nuisance would be the mosquito, but more specifically the Ades aegypti mosquito. The Aedes aegypti is the vector for yellow fever and the cause of the numerous deaths. In her book The American Plague: The Untold Story of Yellow Fever, The Epidemic the Shaped Our History, Molly Caldwell Crosby presents the idea that the mosquito is not just the only reason an epidemic occurred in the 18th century. This story accounts for the disease that broke out across the world and nearly destroyed almost all of North America’s population, which some believe could have been avoided by simple quarantine analysis and sanitary methods.
The dominant group came over from europe carrying multiple diseases that kill of huge portions of the
The Sudan Virus was first discovered in South Sudan in nineteen seventy-six, where it was described as “Ebola Hemorrhagic Fever” but classified as SUDV. Bats were suspected to harbor the virus because of the distantly related filo virus, MARV. MARV has been isolated from bats, but no reservoir host has been positively identified. As well as being unclear on how SUDV was introduced into the human
Ebola is one of many hot agents around the world, however it is the deadliest. Ebola outbreaks occur in primates, and are deadly. Ebola is a filoviridae that is extreme, and in most cases fatal, attacking primates, including humans (“Ebola” 1). Ebola has mutated, creating different strands that affects different primates in different ways. There's five different mutations of the Ebola virus: Ebola Zaire, Ebola Sudan, Taï Forest Ebola, Ebola Reston, and Bundibugyo Virus (“Ebola” 1).
Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.
Invasive species are a big problem to the United States ,because they can cause billions of dollars in damage. In this paper it will reveal some of the most known invasive species in the Florida everglades. The different Invasive species that will be discussed are the Giant African Snail, the Brazilian Pepper Tree, and the Cuban Treefrog. The first invasive species is the Giant African Snail. It originated from Africa and was first presented to Florida as being a pet.
From the gentlest to the most fatal, the Ebola trio is ranked as Marburg, Ebola Sudan, and Ebola Zaire. However, in a quest to determine a new strain of Ebola, scientists discover a harmless-to-humans but fatal-to-monkeys agent known as Ebola Reston. Marburg virus can affect humans like nuclear radiation by virtually damaging all the tissues in their bodies. Ebola and Marburg are both viruses that cause hemorrhagic fevers, organ failures, brain damage, and death. AIDS, a virus emphasized alongside the Ebolas, is stated to be the most environmental disaster of the twentieth century (page 227).
Invasive species have been a massive problem in Hawaii since the 17s and 18 hundreds. At first, it wasn’t that big of a deal, but the influx of invasive species grew over time, and it became a dangerous slippery slope. Species that were once alienated poured into Hawaii and destroyed indigenous species that had been native to Hawaii for a very long time. Since then, the Hawaiian people and advocates of removing invasive plants and animals have banded together to help remove these species. There has been a great global effort to remove invasive species in all places, but the hasty spread of them has made it almost impossible to eradicate a lot of them. I think my group can majorly help with this by educating you all about the seriousness of invasive species.
The term alien no longer has the mystery and excitement and possibility behind it, rather it has become a more colloquial term in regards to disbelieve. Considering the fact that there are movies and shows about aliens, one has to wonder, where did the idea of aliens come from? For over a thousand years people have reported seeing strange objects flying in the sky. Today the unknown flying objects are know as-UFOs, that continue to visit us, on a regular basis or so some say.
DWV has been detected in various insect groups that play different roles in ecosystem, including insect predators, pollinators and pest species that live inside the
The Zika virus was first observed in monkeys and is spread by mosquitoes in humid climate areas such as Uganda and Tanzania. Zika virus is very similar to the virus that causes dengue. To prevent yourself from this virus is to avoid visiting tropical areas. Should you have to visit a tropical country then, I strongly advise you to wear long sleeves and long trousers to avoid being bitten by insects, which is the main infection route. If you have been bitten by an insect while travelling seek medical attention.
Malaria is the most common disease in third world countries with a tropical climate; the disease is caused by a parasite called Plasmodium, which is transmitted through the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. Symptoms of malaria include fever, headache, and vomiting, and usually appear between 10 and 15 days after the mosquito bite. If not treated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. In many parts of the world, the parasites have developed resistance to a number of malaria medicines.
