Xylem maturation depends on cambial age rather than diameter growth in Shorea macrophylla by the model selections for radial variations cell length, wood fiber traits, and basic density. Radial anatomical characteristics properties were investigated 23-year-old (engkabang) trees planted Sarawak, Malaysia. The effects of rates manner xylem determined based selected mixed-effects models. best mod...

although in the recent years, the effect of ground water level on radial growth of black alder has attacked attentions of scientist but to comprehensively interpret the results of such studies, we need to investigate the independent influence of climate on ring width and other wood anatomical features of this species. hence, in current study, the influence of climatic factors on the annual ring...

Tree mortality is a key factor influencing forest functions and dynamics, but our understanding of the mechanisms leading to mortality and the associated changes in tree growth rates are still limited. We compiled a new pan-continental tree-ring width database from sites where both dead and living trees were sampled (2970 dead and 4224 living trees from 190 sites, including 36 species), and com...

Unprecedented rates of climate warming over the past century have resulted in increased forest stress and mortality worldwide. Decreased tree growth in association with increasing temperatures is generally accepted as a signal of temperature-induced drought stress. However, variations in tree growth alone do not reveal the physiological mechanisms behind recent changes in tree growth. Examining...

BACKGROUND AND AIMS The mangrove Rhizophora mucronata has previously been reported to lack annual growth rings, thus barring it from dendrochronological studies. In this study the reported absence of the growth rings was reconsidered and the periodic nature of light and dark brown layers visible on polished stem discs investigated. In addition, the formation of these layers in relation to preva...

2 I. Abstract We measured the impacts of prescribed fire and small clear-cut tree harvesting on carbon dynamics in a mixed-conifer forest in the central Sierra Nevada. Soil CO 2 efflux, above ground tree biomass, annual tree radial growth, and ecosystem carbon stored as litter, fine root and in the mineral soil were measured in four treatment sites: an un-manipulated control, a prescribed fire ...

Radial growth of trees is closely related to canopy activity. Revealing the relationship between radial and activity great significance for forest protection under climate change. In this study, we built tree-ring chronologies two tree species, spruce (Picea aspruceerata) Chinese pine (Pinus tabuliformis), from Helan Mountains in arid region northwest China. Correlation coefficients were then c...
