Proposals to prevent and control exotic invasive species

Abstract

Invasive alien species are currently recognized as the second global cause for the loss of biological diversity in the world. This theme is still little known in Brazil as well as the South American continent where there is a lack of basic information, public policies and legal frameworks, prevention and control programs and academic and corporate perception about the seriousness of the problem. The objective of this article is to propose some bases for the subject involving fundamental concepts established in the Convention on Biological Diversity, basic science issues regarding biological invasions such as propagule pressure, vectors and routes of dispersion and risk analysis, and discuss action priorities.
