Old-growth temperate rainforests are, per unit area, the largest and most long-lived stores of carbon in the terrestrial biosphere, but their carbon dynamics have rarely been described. The endangered Fitzroya cupressoides forests of southern South America include stands that are probably the oldest dense forest stands in the world, with long-lived trees and high standing… More

Relationships between environmental factors and stem radius variation at short temporal scales can provide useful information regarding the sensitivity of tree species’ productivity to climate change. This study used automatic point dendrometers to assess the relationship between environmental variables and stem radius contraction and increment in ten Fitzroya cupressoides trees growing in two sites, the… More

Little is known about how old‐growth and massive forests are responding to environmental change. We investigated tree‐ring growth and carbon isotopes of the long‐lived and high biomass Fitzroya cupressoid es in two stands growing in contrasting environmental conditions in the Coastal Range (~300 years old) and Andean Cordilleras (>1500 years old) of southern Chile. The interannual variability… More
