Introduced vertebrate species and their interactions with native animal and plant species will be the central theme of the symposium. Animal invaders can have roles as competitors, predators, herbivores, and granivores. In turn, the distribution, abundance, and population dynamics of the invader can be affected by these same relationships, as well as by changes in habitat structure from invasive plants. Outcomes of these interactions are often considered harmful; others are considered acceptable or, in some cases, even beneficial. Not only do introductions have ecological implications, they are further complicated by sociological, political, economic, and cultural influences. Although many animal introductions are accidental, some introductions are deliberate. Purposeful introductions that are done as part of commonly accepted land- and resource-management programs are ongoing in most parts of the world. This symposium will examine both types of introductions from ecological, conservation, and policy perspectives, with views encouraged from areas throughout the world. Presentations will address invasive-species characteristics, invaded communities, invader impacts, and positive and negative outcomes of control programs in sequential, rather than breakout, sessions. Because of the nature of the sequential sessions, only a limited number of oral presentations will be accommodated. Contributed posters will be an essential part of the program. A special evening poster session and reception with authors present will allow plenty of extended discussion among conference participants. Symposium proceedings will be published and distributed to all registrants.
