La composition g\u00e9n\u00e9tique des populations change d\u2019une g\u00e9n\u00e9ration \u00e0 l\u2019autre. Cette \u00e9volution r\u00e9sulte de plusieurs facteurs\u00a0: la mutation, la recombinaison, les flux de g\u00e8nes et la migration, la d\u00e9rive g\u00e9n\u00e9tique, les s\u00e9lections naturelles et l\u2019\u00e9pig\u00e9n\u00e9tique.<\/p>\n
Nos for\u00eats sont confront\u00e9es \u00e0 plusieurs crises \u00e9cologiques : changements climatiques, effondrement de la biodiversit\u00e9, \u00e9puisement des ressources naturelles\u2026<\/p>\n
Durant l\u2019expos\u00e9, Alexis Ducousso nous donnera des connaissances de bases en g\u00e9n\u00e9tique afin de bien comprendre les enjeux. Il\u00a0 analysera ensuite les r\u00e9ponses des for\u00eats face aux diff\u00e9rentes crises \u00e9cologiques. Des s\u00e9quences seront d\u00e9di\u00e9es \u00e0 diff\u00e9rentes applications concernant la gestion et la conservation des for\u00eats. Nous apprendrons par exemple que le renard ou le geai sont des agents importants pour l\u2019\u00e9volution g\u00e9n\u00e9tique et donc le bon fonctionnement \u00e9cologique de nos for\u00eats.<\/p>\n
Alexis DUCOUSSO est ing\u00e9nieur de recherche \u00e0 l\u2019INRA Bordeaux-Aquitaine. Il est titulaire d\u2019un doctorat de g\u00e9n\u00e9tique et de biologie des populations v\u00e9g\u00e9tales. Alexis DUCOUSSO allie les qualit\u00e9s d\u2019un chercheur avec celles d\u2019un forestier. Il met en pratique les r\u00e9sultats de ses recherches dans sa gestion d\u2019une for\u00eat pilote de 68 ha o\u00f9 il applique des techniques innovantes pour restaurer et pr\u00e9server la biodiversit\u00e9.<\/i><\/p>\n
