The savannas (cerrado) of south-central Brazil are currently subjected to frequent anthropogenic burning, causing widespread reduction in tree density. Increasing concentrations of atmospheric CO

Summary 1. Plants can provision seeds by optimizing seed size, number and nutrient content to maximize parental fitness. According to the McGinley‐Charnov hypothesis, seed size should be determined by the ratio of carbon to nitrogen (C/N) available

� Springer-Verlag 2005 Abstract Tree-ring characteristics in four species were ex- amined to address whether co-occurring mature trees of dif- ferent successional status respond differently to drought, and whether saplings of these species have a g

To address the role of canopy-seedling feedbacks in the structure and dynamics of mixed conifer broad-leaved forests in the eastern US, we monitored seedling regeneration patterns and environmental conditions in the understorey of stands dominated by

We used sap flow as a measure of whole-tree function to examine how coniferous and broad-leaved species in mixed temperate forests differ in canopy-level transpiration and photosynthetic rates. We used heat dissipation probes to measure whole-tree sa

Summary We investigated how light and CO2 levels interact to influence growth, phenology, and the physiological processes involved in leaf senescence in red oak (Quercus rubra) seedlings. We grew plants in high and low light and in elevated and ambie
