Invasive or Exotic Species

Today, animals and plants can travel around the world for hours and days with airplanes and boats. Although their existence is usually harmful, some scientists believe they can actually be a catalyst for biodiversity. Invasive or alien species changed the Chesapeake Bay area; at the same time, a negative and positive effect was created. "A foreign species is a plant, animal, or a microorganism that moves from one geographical area to another geographical area." (5) From a region that balances evolution to a region where there is no natural competitor I will.

Invasive species: 46% of all endangered species listed by the Federal Government are considered to be at risk, primarily due to invasion by foreign species or competition or predation. Non-native species or foreign countries of plants, animals and insects invade the wilderness areas throughout the country, expelling and destroying native species. Almost all the wilderness is adversely affected by invasive species and requires considerable resources to solve this general and complicated problem.

Invasive species, alien species, foreign pests, biological contamination, non-native species or invasive alien species are common names for classifying non-native animals, microorganisms, diseases or pests. These pests do not inhabit the area that causes problems. It invades new areas and increases population, resulting in disordered population growth and spread, causing economic or environmental problems. . Invasive species, unlike invading countries and areas, are usually endemic species of the country and region and are causing problems now. California has an average of about 9 new large invertebrates on average every year, of which about three will be insect pests. This is the proportion of new species every 40 days. Hawaii and Florida acquire new species with about 15 kinds annually

When alien species are released into a new environment, they may become intrusive. Invasive non-native species are species that are likely to cause or cause serious economic or environmental harm. It is not necessarily invasive when all non-conventional species are released to the new system. Indeed, the majority of individual referrals are considered not to affect, and the introduced individuals could not lead to an established population. In other cases, the introduced species are certainly established, but their presence gives little or no ecological or economic impact for why they are not fully understood.

An invasive species, also known as "alien species" or "non-native species", is a species into which humans have been introduced into the ecosystem and not evolved. Invasive species such as crabs adversely affect their invading habitat and biological area as they usually do not have natural predators, so their population is not managed. Invasive species change habitat, alter ecosystem function and ecosystem services, destroy biodiversity, squeeze and eat native species, and have immense economic loss to human activity There is a possibility to cause.
