New species are introduced into areas to either get rid of another animal e.g. the cane toad came to Australia to get rid of some kind of bug or and animal is accidentally taken to another country.
A new species, when introduced to an ecosystem, will compete with the indigenous species for food and resources. If the new species is predatory, it may also begin preying on the indigenous species, so the native populations will decrease sharply.
Those are invasive species.
The main factors involved in the formation of new species are genetic isolation, genetic mutations, natural selection, and geographic barriers. When a population becomes isolated from the rest of its species and evolves genetic differences due to mutations and natural selection over time, it can eventually become distinct enough to be classified as a new species. Geographic barriers can also play a role in isolating populations and driving speciation.
When a certain species is divided up into two or more separate populations (geographically, for example) they continue to evolve (via natural selection) and over time the two (or more) populations will be so different from each other that they will not be able to reproduce, and will fit the criteria of different species.
When a new species evolves from an existing species, it results in speciation, which is the formation of a distinct species that is reproductively isolated from the original species. This can occur due to various factors such as geographic isolation, genetic mutations, or changes in environmental conditions that lead to evolutionary divergence. The new species will have its own unique traits and characteristics that distinguish it from its ancestor.
Yes, geographic barriers guarantee the formation of new species.

Introduced species that are relatively new and untested can lead to economic losses as far as the mass production is concerned.
"Invasive Species" is a term used to describe a species that is taken from it's natural environment and introduced somewhere else. The species then cause harm to the new environment it was introduced in.
When a new species is introduced to a new environment, several outcomes can occur. The species may thrive and establish a stable population if conditions are favorable and it finds ample resources. Alternatively, it could face challenges such as competition with native species, lack of food, or unsuitable environmental conditions, leading to its decline or extinction. In some cases, the introduced species may become invasive, disrupting local ecosystems and threatening native species.
Introduced species and habitat loss are the primary causes of extinction of native species in New Zealand. Introduced species such as feral cats, foxes, rats and stoats have decimated some native populations. Even the brushtail possum, rainbow lorikeets, black swan and cockatoos which have been introduced from Australia, threaten the habitat of native New Zealand species.

Yes, species are being introduced to new ecosystems accidentally through activities such as global trade and travel. Additionally, some species are intentionally introduced into new ecosystems for various reasons, such as pest control or agriculture. These introductions can have both positive and negative effects on the receiving ecosystems.
