invasiivne

Invasiivne is an adjective used in several languages to describe something that invades or spreads beyond its original boundaries. In ecology, it often refers to invasive species—organisms introduced to a new environment, intentionally or accidentally, that establish self-sustaining populations and spread, frequently to the detriment of native species, ecosystem processes, or human economies. In medicine, invasive describes growth or spread into surrounding tissues, as in invasive cancer cells or invasive infections that penetrate barriers and disseminate within the body.

The term originates from the Latin invasio and has cognates in many European languages with similar meanings. In ecological contexts, invasive species typically exhibit high reproductive rates, broad environmental tolerance, and effective dispersal, enabling them to outcompete natives, alter habitats, reduce biodiversity, and impact agriculture and infrastructure. Common examples include the zebra mussel in North America, kudzu in the southeastern United States, and the cane toad in Australia.

Management of invasives emphasizes prevention and rapid response. Measures include border controls, early detection, mechanical or chemical control, biological control where appropriate, and habitat restoration to support native species. International and national biosecurity policies aim to reduce introductions and limit spread.

In medical settings, invasion refers to the process by which pathogens or malignant cells infiltrate adjacent tissues or migrate to distant sites, influencing diagnosis and treatment. Understanding invasiveness helps guide therapeutic strategies and risk assessment. The form invasiivne may appear as the feminine or neuter version of the adjective in some languages.
