Linvasivité

Linvasivité refers to the invasion of non-native species into an ecosystem. This can occur through various means, including human activity such as trade, travel, and agriculture, as well as natural processes like wind or water dispersal. Non-native species may outcompete native species for resources, altering the balance of the ecosystem and potentially leading to extinctions.

Linvasivité can have significant environmental, economic, and social impacts. Environmental impacts include the degradation of habitats, displacement of native species, and alterations to nutrient cycles. Economic impacts may arise from the loss of resources, damage to infrastructure, and costs associated with invasive species control and management.

Examples of invasive species include the zebra mussel, which can clog waterways and disrupt aquatic ecosystems; the brown tree snake, which has led to declines in bird populations in Guam; and the European fire ant, which can displace native ant species and cause economic losses.

Linvasivité is a widespread problem, affecting many regions of the world. The International Convention on the Control of Harmful Marine Organisms and Ship Ballast Water is an example of an international agreement aimed at preventing the spread of invasive species.

Efforts to address linvasivité include the development of invasion risk assessments, education and awareness campaigns, and the implementation of control measures such as biological control, physical removal, and chemical treatment. Researchers are also working on the development of genetic tools to predict and prevent the establishment of invasive species.
