Adaptation aux changements climatiques. Les changements climatiques sont cause de discordance entre la g\u00e9n\u00e9tique naturelle des arbres et les lieux o\u00f9 ils poussent. Des semis autrefois bien adapt\u00e9s \u00e0 une r\u00e9gion donn\u00e9e sont maintenant mal adapt\u00e9s \u00e0 leur environnement en raison des changements climatiques. Au cours de la derni\u00e8re d\u00e9cennie, cette m\u00e9sadaptation entra\u00eene davantage de pertes en raison des ravageurs tels que le dendroctone du pin ponderosa en Colombie- Britannique et le d\u00e9p\u00e9rissement de la cime des \u00e9pinettes en Alberta.<\/p>\n
Gr\u00e2ce au financement de G\u00e9nome Canada, des chercheurs appliqueront les technologies de pointe de la g\u00e9nomique, de m\u00eame que l\u2019analyse g\u00e9ospatiale et la mod\u00e9lisation climatique \u00e0 deux des arbres les plus importants de l\u2019Ouest canadien \u2013 le pin tordu latifoli\u00e9 et l\u2019\u00e9pinette. Tous les ans, on r\u00e9colte du bois pour une valeur d\u2019environ 10 milliards de dollars dans ces provinces. On s\u2019attend \u00e0 une diminution du volume de ces r\u00e9coltes de 35 % au cours du pr\u00e9sent si\u00e8cle.<\/p>\n
Les chercheurs effectuent le s\u00e9quen\u00e7age des semis pour mieux comprendre les g\u00e8nes qui interviennent dans l\u2019adaptation aux conditions climatiques locales. Gr\u00e2ce \u00e0 leurs r\u00e9sultats, il deviendra possible de planter les bons arbres dans les bonnes r\u00e9gions climatiques, d\u2019am\u00e9liorer la sant\u00e9 \u00e0 long terme des for\u00eats et d\u2019assurer des avantages \u00e9conomiques qui se chiffreront en centaines de millions de dollars annuellement. Divers intervenants ont \u00e9t\u00e9 invit\u00e9s \u00e0 participer pour mieux comprendre les enjeux socio\u00e9conomiques en cause, ce qui devrait mener \u00e0 des recommandations strat\u00e9giques pour un meilleur am\u00e9nagement des for\u00eats.<\/p>\n","protected":false},"excerpt":{"rendered":"
