Retrospective Analysis of Wood Anatomical Traits Reveals a Recent Extension in Tree Cambial Activity in Two High-Elevation Conifers [PDF]
, 2017 The study of xylogenesis or wood formation is a powerful, yet labor intensive monitoring approach to investigate intra-annual tree growth responses to environmental factors.

Disentangling the Evidence of Milankovitch Forcing From Tree-Ring and Sedimentary Records
Frontiers in Earth Science, 2022 Tree-ring records constitute excellent high-resolution data and provide valuable information for climate science and paleoclimatology. Tree-ring reconstructions of past temperature variations agree to show evidence for annual-to-centennial anomalies in ...

A model analysis of climate and CO2 controls on tree growth and carbon allocation in a semi-arid woodland [PDF]
, 2016 Many studies have failed to show an increase in the radial growth of trees in response to increasing atmospheric CO2 concentration [CO2] despite the expected enhancement of photosynthetic rates and water-use efficiency at high [CO2].

Computer-Graphing of Annual Ring Widths During Measurement [PDF]
The Forestry Chronicle, 1983 Annual ring width data produced by the DIGI-MIC tree ring measurer are transmitted to an APPLE II Plus microcomputer providing the user with an immediate graphical display of the radial growth pattern of the tree. Line graphs of ring widths along radii of a stem cross section and (or) the average for successive stem sections can be compared visually ...

Determination of the number of sapwood annual rings in oak in the region of southern Moravia
Journal of Forest Science, 2006 The paper deals with the determination of the number of sapwood annual rings in oak (Quercus sp.) in relation to altitude, locality and stand age. Several different groups of samples were used from two localities of southern Moravia.

Effect of growth rate and latewood content on basic density of wood from 120-to 154-Year-old natural-grown Teak (Tectona grandis L. f.) [PDF]
, 2014 The relationship between the radial variations of growth ring features and basic density were investigated in juvenile and mature wood for five 120-to150-year-old trees of Tectona grandis L. grown naturally in moist deciduous forest of Thane,Maharashtra.

Results from the CASTLES Survey of Gravitational Lenses
, 1998 We show that most gravitational lenses lie on the passively evolving fundamental plane for early-type galaxies. For burst star formation models (1 Gyr of star formation, then quiescence) in low Omega_0 cosmologies, the stellar populations of the lens ...
