Invazívnos

Invazívnos, also known as invasion, refers to the act of one species, typically an animal or plant, entering and establishing itself in an ecosystem where it is not native. This process can have significant ecological and economic impacts. Invasive species often outcompete native species for resources such as food, water, and habitat, leading to a decline in biodiversity. They can also alter ecosystem functions, such as nutrient cycling and water quality, and may introduce diseases or pests to which native species have no immunity.

Invasive species can be introduced through various means, including accidental transport via ships, aircraft, or vehicles, deliberate introduction for purposes such as agriculture or aquaculture, or as a result of human activities that alter habitats, such as deforestation or urbanization. Once established, invasive species can be difficult to eradicate due to their adaptability and reproductive capabilities.

Examples of invasive species include the zebra mussel in freshwater ecosystems, the brown tree snake in Australia, and the kudzu vine in the southeastern United States. Each of these species has had significant impacts on local ecosystems, highlighting the importance of monitoring and managing invasive species to protect native biodiversity and ecosystem services.
