Dendroclimatology of Pinus sylvestris L. in the British Isles
A study of the properties of tree-ring density and ring-width chronologies from five sites in the British Isles, two in Sweden and two sub-fossil sites in Northern Ireland is described. The technique of x-ray densitometry is used to measure density. It is shown that it is possible to use x-ray …

Historical growth rates and changing climatic sensitivity of boreal conifers
… of different standardisation techniques, used in dendroclimatology to remove internal, non-climate related growth trends in measured series of ring-widths, is explored with an emphasis on the efficiency of the Regional Curve Standardisation (RCS) technique. The approach adopted here makes …

Radial growth response of eastern hemlock to infestation of hemlock woolly adelgid
Hemlock woolly adelgid (Adelges tsugae Annand) is causing defoliation and mortality of eastern hemlock (Tsuga canadensis (L.) Carrière) in the eastern United States. The objectives of this study were to quantify changes in tree-ring width and wood anatomy for trees that survived adelgid …

Applications of Box-Jenkins methods of time series analysis to the reconstruction of drought from tree rings
The lagged responses of tree-ring indices to annual climatic or hydrologic series are examined in this study. The objectives are to develop methods to analyze the lagged responses of individual tree-ring indices, and to improve upon conventional methods of adjusting for the lag in response in …

Exploring high-resolution carbon isotopes in archaeological charcoal as a rainfall seasonality proxy
Rainfall in present-day South Africa is distinctly seasonal, with a Summer Rainfall Zone (SRZ) in the east, a Winter Rainfall Zone (WRZ) in the west, and a Year-Round Rainfall Zone (YRZ) along the south coast and interior between them. Understanding shifts in these zones during Late Pleistocene …

Application of a New Tree-Ring Based Drought Reconstruction Method at Multiple Forest Sites Across Indiana, U.S.A.
<p>This thesis research used techniques of dendrochronology to investigate the efficacy of using multiple co-occurring species (MCOS) in a climate reconstruction model compared to a single species (SS) in four old-growth forests in Indiana: Pioneer Mothers Memorial Forest (PM), Donaldson Woods …

Dendroklimatologische und dendroökologische Untersuchungen des Zuwachsverhaltens von Buche und Fichte in naturnahen Mischwäldern
Vor dem Hintergrund sich verändernder Umweltbedingungen durch den allgegenwärtigen Klimawandel wächst das Interesse an Vorhersagen zur zukünftigen Waldentwicklung. Der prognostizierten Häufung von Witterungsextremen wird ein wesentlicher Einfluss auf das Wachstum und die Vitalität der Waldbaumarten …

A Multi-Millennial Drought Reconstruction for West-Central New Mexico Using Rocky Mountain Juniper (<i>Juniperus scopulorum</i>, Sarg.)
<p>A new multi-millennial tree-ring record from living and remnant Rocky Mountain juniper (<em>Juniperus scopulorum</em>, Sarg.) wood from Candelaria in west-central New Mexico is used to determine the temporal and spatial variability of scPDSI over the past two millennia (B.C. 492 to A.D. 2014). …

Colorado's Large Snow Events' Impact on Tree Ring Growth and Dillon Reservoir
<p>Meteorological observations from 1894 through 2010 suggest that 17 historically large snow events occurred in the mountains of Colorado within Denver's water supply region. Of these 16 events, 14 can be identified in precipitation sensitive tree ring records as positive climatic pointer years. …

Tracking climate signals in tropical trees
The tropical warm pool waters surrounding Indonesia are one of the equatorial heat and moisture sources that are considered as a driving force of the global climate system. The climate in Indonesia is dominated by the equatorial monsoon system, and has been linked to El Niño-Southern Oscillation …

Is Chir Pine Displacing Banj Oak in the Central Himalaya? Socioeconomic Implications for Local People and the Conservation of Oak Forest Biodiversity
<p>Various studies have suggested that chir pine (Pinus roxburghii) is replacing banj oak (Quercus leucotrichophora) in the Central Himalaya. Five sites with three different types of forests (banj oak, chir pine and mixed oak-pine) were sampled to compare the diversity of their vegetation and to …
