Abstract(s)
Wildlife trade is currently the most important and increasing source of vertebrate
invasive species. However, exhaustive analyses of potential side effects
of trade regulations on this pathway of introduction are lacking. We
addressed this by combining environmental niche models and global trade
data on parrots (Psittaciformes), one of the most widely traded and worldwide
invasive taxa. We used the wild bird trade bans of United States (1992)
and Europe (2005) as case-studies. Results showed that regional bans can
generate geographic redirections in trade, with important consequences on
worldwide invasion risk. While the amount of parrots traded internationally
remained largely constant, changes in trade destination occurred. Consequently,
the world surface predicted at risk of parrot invasions increased with
successive bans. Of concern, a redirection of trade toward developing countries
was observed. Attention should be paid on the mismatch between the global
requirements of invasion management and the regional scales governing trade
regulations
