Extract of sample "Invasive Species"

Response Essay Invasive Species Invasive species in certain regions are assumed to threaten the rest of the ecosystem especially those species which have became extinct. It so happens when any specie increases in population it declines the chances of growth for the others. However, this is an assumption as there is no data or researched hypothesis to support these assumptions; extinct species become scarce due to miscellaneous biodiversity factors and due to these their population starts declining in their native regions. Some researchers consider that human interference in the ecosystem has caused this disrupt, either directly or indirectly.
Through, pollution environment around the globe changed and it threatened the life span of many species on Earth like Bluebuck, Atlas Bear, Cape Lion, Bali Tiger, Honshu wolf, Tule Shrew, etc (Kolbert, 2014). Similarly, when ecologist harvested certain species in a foreign environment it also disrupted the biodiversity of the area and numerous species as well. It cannot be exactly claimed what became the cause of threat for extinct species, but there are many unknown factors to humans (insufficient research by nature scientists) about the environment and biodiversity of life on Earth. Brown tree snake of Guam is one of the example, which the author discusses in the article.
Yet, it is imperial to study the impact of exotic plants, invasive predators and pathogens in a foreign environment as their nourishment and existence will depend on numerous factors in the new environment (Gurevitch and Padilla, 2004).
Conclusively, it is significant to research, plan, protect, and preserve the extinct species in their native and natural environment as new regions will impact on their growth in an unknown manner and that cannot be ascertained by humans in a rapid manner.

Invasive Species

...? The Asian Tiger Mosquito Teacher               The Asian tiger mosquito is an invasive species which has the ability to undergo genetic mutation as it interacts with various viral species and as it adapts to the low temperature of various temperate areas. It is the vector of several viruses including those causing dengue. It has spread from Southeast Asia to North and South America, Europe, Africa and Australia through the transportation of tires. Several attempts have been made to control it but all have failed but there is a promise in genetic engineering in order to manipulate this species whose genetic make-up easily mutates. The Asian Tiger Mosquito The Asian tiger...

Invasive Species

...The Positive and Negative Impact of Alien Species on South African Diversity Introduction The biodiversity of Southern Africa is one of the richest in the world. It has been totalled that the area maintains 10,000 known marine fauna and flora species (Branch, 2005). Many of these species are endemic to the region, and therefore are particularly susceptible to extinction, as there will be no other place to find them, if it happens that they're overtaken by invasive alien species. Thorough research has been done on both indigenous land and indigenous ocean life in these areas. Likewise, investigations have been designed around further evaluation of the...

...Order: Hymenoptra Family: Apidea Genus: Apis Species: mellifera Subspecies: scutellata Apis mellifera scutellata has been chosen for this research on invasive species which is commonly known as Africanized honey bee/Brazilian Bees/Killer bee. Background Information The ancestors of Apis mellifera scutellata live through out Africa, south of Sahara Desert. In the year 1956, few colonies of mellifera scutellata were brought to Brazil by Dr.Warwick Kerr (Kerr 1967), a geneticist to cross breed with the European Honey Bees (EHB) which did not thrive in tropics of South America to revive the declining apiculture industry. In the year 1957 accidentally few African queen bees along with swarms of European worker bees, escaped... and...

Introduced or invasive species

...Invasive or Introduced Species" Introduction An introduced or invasive species is a species inhabiting out of its native location and has been introduced by human actions either by chance or by wish. In certain cases these species may not adapt themselves to the new-fangled environment and therefore they display very little survival rate, on the other hand some of the species survive well and proliferate in the newly introduced novel habitat. It is observed that some of the introduced species are deteriorating the natural environment to which they have been introduced, on the other hand some of the...

The effects of invasive species on recreational fishing

...Effects of Invasive Species Invasive species are organisms that adversely affect the natural habitats of other organisms in nature (Coulatti 137). The reason they are referred to as organisms is that they can constitute of both plants and animals. Animal invaders are like beavers. Beavers are categorized as invasive because they can ruin natural landscape building their dams. The World Conservation Union puts invasive species as the second highest threat to bio-diversity (WCU, 4). The threats the invasive species pose are economical, environmental and social impacts. There are various...

Invasive Species: Effects & Management

...effect (Oppel, Beaven, Bolton, Vickery, and Bodey, 2010). The population of stoat was not eliminated by poison, but rats and possum were eliminated by poison. To survive, Stouts began feeding on birds and their eggs, greatly affecting the ecosystem. This is because the number of birds greatly reduced, thus the process of pollen transfers was affected. It is therefore important to understand that trying to eliminate an invasive species might lead to the destruction of the eco system, in case the method used for elimination is not conducive. It is also important to understand that the removal of invasive animals also has some positive impacts (Gallardo and Aldridge, 2013). One such...
