Early experiments with overlapping cuts to the stems of trees demonstrated that lateral flow within the stem must be possible to allow such trees to maintain water flow to their leaves. We present a mathematical approach to considering lateral flow in stems by treating the xylem as an anisotropic medium for flow and develop an expression of its conductivity in the form of a tensor. In both 3D m...

We present here the 2001–2004 results of observational field studies aimed at quantifying tropical timberline climate and radial increment of Pinus hartwegii Lindl. trees on Nevado de Colima, in the middle of the North American Monsoon region. An automated weather station was installed at 3760 m a.s.l., 19834.7789N latitude, 103837.1809W longitude, within a forest where multi-century tree-ring ...

This review deals with the latest developments in dendroclimatology focused on climate reconstruction. It presents results from research carried out during the period 1992–2001, when both the geographical and chronological extension of tree-ring data were greatly improved. Research projects are presently being carried out in nearly all the main forest land areas of the Subarctic and Subantarcti...

Species complementarity by morphological and physiological trait differences could cause distinct temporal spatial use of resources. Accordingly, mixed stands may enhance production, biodiversity and/or provide a better adaptation to future climate conditions. We aim identify species in intra-annual stem radial variation patterns, recognize species-specific responses contrasting weather conditi...

Preand post-fertilization tree growth in unfertilized and fertilized thinned stands was used to estimate the 7-year radial growth response of operationally fertilized subalpine fir (Abies lasiocarpa). Despite large stem growth variability in thinned, and thinned and fertilized stands, the 7-year growth increment of fertilized trees was apparently 51–57% larger than the estimated growth that wou...

To understand better the adaptation strategies of intra-annual radial growth in Pinus halepensis and Pinus sylvestris to local environmental conditions, we examined the seasonal rhythm of cambial activity and cell differentiation at tissue and cellular levels. Two contrasting sites differing in temperature and amount of precipitation were selected for each species, one typical for their growth ...
