Persistence at the Tree Line: Old Trees as Opportunists

While old trees have long been of interest, their significant role in responding to climate change at northern tree lines has been overlooked. Long-lived black spruces at the tree line in Labrador show a radial growth response that is synchronous with recent climate warming. The ability of individua...

description While old trees have long been of interest, their significant role in responding to climate change at northern tree lines has been overlooked. Long-lived black spruces at the tree line in Labrador show a radial growth response that is synchronous with recent climate warming. The ability of individuals to persist with suppressed radial growth rates during adverse growing conditions may have significant implications for the rate at which these trees are able to respond when conditions become favourable. RÉSUMÉ. Même si les vieux arbres revêtent de l’intérêt depuis longtemps, on a négligé de considérer le rôle important qu’ils jouent en matière de réaction au changement climatique à la hauteur des limites forestières boréales. Au Labrador, les épinettes noires de longue date se trouvant à la limite forestière affichent une croissance radiale qui est synchrone avec le récent réchauffement climatique. L’aptitude des individus à persister malgré des taux de croissance radiale opprimés lorsque les conditions de croissance sont déficitaires peut avoir des incidences importantes sur le taux de réaction de ces arbres lorsque les conditions deviennent favorables.
