Age-dependent variations of radial growth, intra-annual density fluctuations an...

Vieira, Joana

Dendrochronology generally assumes that climate-growth relationships are age independent once the biological growth trend has been removed. However, tree physiology changes with age, namely photosynthetic capacity and hydraulic conductivity. Additionally, in a scenario involving climate change it is important to verify if the relationship between tree growth and climate is also changing. We tested whether the r...

Dendrochronology generally assumes that climate-growth relationships are age independent once the biological growth trend has been removed. However, tree physiology changes with age, namely photosynthetic capacity and hydraulic conductivity. We tested whether the radial growth response to climate and the intra-annual density fluctuations (IADFs) of Pinus pinaster Ait. varied with age. Trees were sampled in Pinh...

Climate projections for the Mediterranean area estimate a decline in total precipitation, warmer temperatures and a higher frequency of extreme drought events. It is important to understand how trees respond to these climatic changes and which wood anatomical structures best document the trees response to those changes. The present work investigates the climatic signal of tree-ring width (TRW), latewood width (...
