INTRODUCED SPECIES Meaning and
Definition
-
An introduced species, also known as an alien, non-native, non-indigenous, or exotic species, refers to a plant, animal, or other organism that is brought or introduced into an ecosystem or region where it is not historically found or native. Introduced species can be intentionally or accidentally introduced by humans, either for economic purposes, such as agriculture or ornamental plants, or through human-mediated activities, like shipping and commerce. They can also be introduced as pets or as a result of animal or plant escapees from captivity.
Introducing species into new environments can have various consequences. In some cases, introduced species can thrive and establish self-sustaining populations, becoming invasive species. These invasives can have detrimental effects on the native ecosystems, outcompeting native species and affecting native biodiversity. They can disrupt ecological processes, alter habitats, and even lead to the extinction or endangerment of native species.
However, not all introduced species become invasive. Some may fail to survive or reproduce in the new environment or simply coexist with the native species without causing significant harm. In such cases, they are referred to as naturalized or non-invasive introduced species.
The study of introduced species and their impacts on ecosystems falls under the field of invasion biology. Understanding the ecological and socioeconomic impacts of introduced species is crucial for effective management and prevention of their negative effects on our natural environments.
Etymology of INTRODUCED SPECIES
The etymology of the word "introduced species" can be broken down as follows:
1. Introduce: The word "introduce" originates from the Latin word "introducere", which combines "in" (meaning "into") and "ducere" (meaning "to lead" or "to bring"). "Introduce" originally meant to lead or bring someone or something into a place or company.
2. Species: The word "species" has its roots in the Latin word "species", which primarily meant a particular kind or appearance. In the context of biology, "species" refers to a group of organisms that share similar characteristics and are capable of interbreeding.
Combining these two terms, "introduced species" refers to a species of plant, animal, or microorganism that has been intentionally or unintentionally brought into a new environment where it did not previously exist.
