Invasive Species Effects

The invade of alien species - also known as invasive species - is a global issue that should be eminently aware of but often neglected and misconceived as insignificant. There are a variety of possible causes of invasive species found in a non-native environment, but most probably, invasive species are "domestic aliens" that are escalated by people deliberately to new habitats within large nations and between islands. Invasive species are nonindigenous plants and animals from a foreign environment that were forcefully permeated into an outlandish habitat, threatening native wildlife and ecosystems. They are causing negative impacts in numerous ecosystems, pushing many inhabitant plants and animals to the brink of extinction. It is a treacherous

Ecological impacts, Genetic pollution, agricultural damage are some negative effects caused by invasive species. Biological species invasions altered ecological systems in multiple ways. “Worldwide an estimated 80% of endangered species could suffer losses due to competition with or predation by invasive species (panda.org, 2014) ”Some native species may be put at a disadvantage to survive while other species survival is enhanced in physical power due to the change in environment. Genetic pollution might also occur, naturally evolved region specific wild species can be threatened with extinction through the process of genetic pollution. Including, uncontrolled hybridization, introgression (gene flow from one species into the gene pool of another, by the repeated backcrossing of a hybrid with one of its parent species) and genetic aggression and take over, which leads to the replacement of local species as a result in an enchanted advantage of foreign species. Which then possibly leads to the extinction of local animals and plants. (Sciencedirect,

Japan was invaded when the venomous Redback Spiders were first detected in Japan, Osaka in 1995. Redback spiders appear during warm waters, usually January to April in their original country - Australia. Their bites are very commonly occurred, it is the commonest causes of serious and dangerous envenoming. Well known for causing intense and consist pain among the victims, the intensity can prevent victims from sleeping or resting in one- third of the case. (Australian prescriber, 2006) “The dangerous long-legged spider with a distinctive red body is a native of Australia, but somehow has found its way to Japan, where it lurks in dark corners. (Daily mail, 2014)” According to several articles, the heated toilet seats in Japan had attracted Redback spiders to their country. Originally due to their tropical habitats, they wouldn’t be able to survive the cold and harsh winters in Japan, but it is now thought that the heated toilets of many Japanese have in their homes provided a shelter.
