Tree differences in primary and secondary growth drive convergent scaling in leaf area to sapwood area across Europe [PDF]

, 2018
open28siTrees scale leaf (AL) and xylem (AX) areas to couple leaf transpiration and carbon gain with xylem water transport. Some species are known to acclimate in AL : AX balance in response to climate conditions, but whether trees of different species ...

Inter-annual carbon isotope analysis of tree-rings by laser ablation [PDF]

Chemical Geology, 2017
Abstract The stable carbon isotopic analysis of tree-rings for environmental, plant physiological and archaeological applications using conventional methods is occasionally limited by physical constraints (narrow rings) or administrative concerns (requirement for non-destructive sampling) that prevent researcher access to scientifically valuable wood

Growth trends reveal the forest structure during Roman and Medieval times in Western Europe: a comparison between archaeological and actual oak ring series (Quercus robur and Quercus petraea) [PDF]

, 2005
At some point in time, man has influenced nearly all forests in Western Europe. Most of the original forest cover has been converted to arable land and pastures, or has been cut for the supply of firewood and construction timber.

A Test of “Annual Resolution” in Stalagmites Using Tree Rings

Quaternary Research, 2002
AbstractSo-called annual banding has been identified in a number of speleothems in which the number of bands approximates the time interval between successive U-series dates. The apparent annual resolution of speleothem records, however, remains largely untested. Here we statistically compare variations in band thickness from a late Holocene stalagmite

Tree ring record of annual runoff for Issyk Lake, Central Asia [PDF]

Journal of Water and Climate Change, 2018
Abstract Revealing hydrologic variations in the past is helpful to understand the dynamic changes and evolution of a given water body. The widespread long-lived spruce forests growing in the mountainous area around Issyk Lake in Central Asia provide a good opportunity for dendrohydrologic studies about that lake.

Structure and Function of Intra–Annual Density Fluctuations: Mind the Gaps

Frontiers in Plant Science, 2016
Tree rings are natural archives of climate and environmental information with a yearly resolution. Indeed, wood anatomical, chemical and other properties of tree rings are a synthesis of several intrinsic, environmental factors, and interconnected ...

Tree growth acceleration and expansion of alpine forests: The synergistic effect of atmospheric and edaphic change. [PDF]

, 2016
Many forest ecosystems have experienced recent declines in productivity; however, in some alpine regions, tree growth and forest expansion are increasing at marked rates.

Screening for lung cancer: A systematic review of overdiagnosis and its implications

Molecular Oncology, EarlyView.
Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Tree ring study of Cordia alliodora (Ruiz & Pav.) in Colombia

Colombia Forestal, 2016
Cordia alliodora has a high ecological and economical value in the dry forest of Colombia. We documented the relationship between tree growth and climate variables (total annual precipitation, mean annual temperature) and the southern oscillation index ...
