BACKGROUND AND AIMS In trees, bud development is driven by endogenous and exogenous factors such as species and climate, respectively. However, knowledge is scarce on how these factors drive changes in bud size across different time scales. METHODS The seasonal patterns of apical bud enlargement are related to primary and secondary growth in two(More)
Understanding the relationships between bud size and position and bud fate through time is crucial for identifying and subsequently modeling the mechanisms underlying tree architecture. However, there is a lack of information on how bud size drives crown architectural patterns in coexisting tree species. We studied bud demography in two coexisting(More)
The plasticity of radial growth and earlywood anatomy to climate has not been properly assessed. To solve this, we evaluated how growth and earlywood anatomy changed in a Mediterranean ring-porous oak (Quercus faginea) across a climatic gradient. We hypothesized that the anatomical variables will be the most sensitive to climatic stress, particularly to(More)
In trees, reproduction constitutes an important resource investment which may compete with growth for resources. However, detailed analyses on how growth and fruit production interact at the shoot level are scarce. Primary canopy growth depends on the development of current-year shoots and their secondary growth might also influence the number and size of(More)
Contrasted response of Quercus macrolepis growth to climate conditions during summer months indicated increased climate-related control of tree growth at high elevation site modulated by topographic characteristics and tree age. High climatic variability and increased drought conditions lead to reduced growth and increased mortality of several tree species(More)
