Recent advances have improved our methodological approaches and theoretical
understanding of post-photosynthetic carbon isotope fractionation processes. Nevertheless …

The deciduous bark habit is widespread in the woody plant genus Eucalyptus. Species with
deciduous bark seasonally shed a layer of dead bark, thereby maintaining smooth-bark …

Respiration in tree stems is an important component of forest carbon balance. The rate of
CO 2 efflux from the stem has often been assumed to be a measure of stem respiration …

Plant biosilica particles (phytoliths) contain small amounts of carbon called phytC. Based on
the assumptions that phytC is of photosynthetic origin and a closed system, claims were …

There is evidence of continued stimulation of foliage photosynthesis in trees exposed to
elevated atmospheric CO 2 concentrations; however, this is mostly without a proportional …

Storage carbon (C) pools are often assumed to contribute to respiration and growth when
assimilation is insufficient to meet the current C demand. However, little is known of the age …

Stem respiration rates are often quantified by measuring the CO2 efflux from stems into
chambers. It has been suggested that these measurements underestimate respiration …

Under ongoing global climate change, drought periods are predicted to increase in
frequency and intensity in the future. Under these circumstances, it is crucial for tree's …

Stable carbon isotopes are often employed as tracers in plant and soil systems to study the
fate and transformations of carbon as is it assimilated by the forest canopies and then …

RATIONALE Here we report on the successful application of a novel stem‐injection stable‐
isotope‐labeling and probing technique in mature trees to trace the spatial and temporal …
