SUMMARY:Study on mechanisms of human mediated biological invasion in aquati
 c invertebrates via Arctic corridor
DESCRIPTION:Conférence de Victor R. Alekseev\, professeur de l’Institut 
 de Zoologie à l’Académie des sciences de Russie situé à St-Petersbur
 g.Résumé One of the major vectors of human mediated alien species wide s
 preading is transportation with ship ballast water. Dormancy phenomenon in
  invertebrate is a basic metabolic mechanism for such transportation of in
 vasive species. For a long time the dominative both way roots for Atlantic
 -Pacific fauna interchanges were tropic gates. At first it was via long wa
 y around Africa and India (spicy shipping) than in the beginning of 20th c
 entury via Panama channel.  In 21th century the Arctic ice shield melting
  opens a new gate for fast and intensive ship transportation between these
  biogeographic zones\, that creates a new high risk for alien species pene
 tration with ships (both attached to ship surface and inside the ballast w
 ater tanks). This problem is absolutely new for science and economy and ha
 s not been studied yet\, even it should be very important for biological s
 ecurity in many courtiers in America\, Europe and in Asia. Specific condit
 ions of Arctic transportation via Arctic open new chance for successive in
 vasion to another set of species comparatively to tropic roots. This can b
 e resulted in a new wave of biological invasion with ships. Possibilities 
 to block or at least shorten or slow down this harmful process is discussi
 ng.Conférence présentée par le Département de sciences biologiques de 
 l’Université de Montréal dans le cadre de la série « Midi Écologiq
