Invasive species are only considered invasive if they are able to survive and sustain themselves in their new environment. [1] A habitat and the environment around it has natural flaws that make them vulnerable to invasive species. [1] The level of vulnerability of a habitat to invasions from outside species is defined as its invasibility.
Several species have been introduced to areas like North America, Australia, South Africa, Fiji and New Zealand, especially the common myna, which is often regarded as an invasive species. It is often known as "Selarang" and "Teck Meng" in Malay and Chinese respectively in Singapore, due to their high population there.

[8] [13] This species was first introduced as an ornamental to Hawaii around 1888 by Chinese immigrants, and is now considered a serious invader in mesic to wet areas of Maui and Hawaii island. [14] Additionally, it is invasive in South Africa, where it is a declared weed, and propagation of plant material is considered prohibited. [15]
In the Great Lakes, fishing is big business: a $7.5 billion industry, it supports an estimated 800,000 jobs.Unfortunately, the lakes -- the world's largest freshwater ecosystem -- are extremely ...
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
In addition, invasive organisms face new biotic and abiotic factors. Invasion potential has a great impact on whether or not the invasive organism will survive these biotic or abiotic factors. The species' ability to adapt to the new conditions will contribute to the success of the particular invasion.
Members of this species are typically 6–9 cm (2.4–3.5 in) long, although sizes up to 16–20 cm (6.3–7.9 in) are possible. [3] A distinctive white to pale blue-green patch is present near the claw hinge, [ 4 ] reminiscent of the white flags that signalmen used for directing trains—hence the species' common name.
