“…where x i is the tree-ring width in year i and x i-1 is the treering width in the previous year (Douglass, 1920;Fritts, 1976). The aim of the standardization was removing nonclimatic trends due to age and size of trees as well as emphasizing year-to-year variability.…”

Metasequoia glyptostroboides is considered to be a species highly resistant to harmful environmental factors. For this reason it has been introduced to the cities. The climate of Krakow differs from that in its natural range in China. The research was focused on 40-year-old trees, planted in Kraków on fertile alluvial soils with a low level of ground water, in the vicinity of the steelworks. During the period of the highest level of air pollution in the 1970s and 1980s, the radial increment of investigated trees showed an increasing trend. At the end of the 1980s, when the emissions were reduced, a decreasing trend in radial growth was recorded. Throughout the entire period of their life the investigated trees have shown high homogeneity of short-term growth reactions. The sensitivity chronology of the trees was characterized by a high representativeness and a strong high-frequency signal. This may indicate that the investigated trees have shown a large sensitivity to climatic factors. The positive effect on the radial growth of Metasequoia had a cold September in the previous year, and also a cold January, April and May in the year of ring formation. Positive impact on the growth of trees had also the high precipitation occurring in April and August, as well as high air humidity in the spring of the year of ring formation. In the period 1974-2011 fifteen signature years were found. The analysis of the climatic conditions in these years confirms the results of the statistical analyses.

“…The EPS allows assessing the representativeness of constructed chronologies (Wigley et al, 1984;Briffa and Jones, 1990). The average relative difference in the radial increment of trees was evaluated with the use of mean sensitivity (MS) (Douglass, 1920;Fritts, 1976).…”

“…Once photographed, otoliths were visually crossdated to ensure that the correct calendar year was assigned to each growth increment. A fundamental technique of dendrochronology, crossdating is based on the assumption that some aspect of climate limits growth, and as climate varies over time, it induces a synchronous growth pattern in all individuals from a given species and region (Douglass 1920, Fritts 1976, Yamaguchi 1991, Stokes & Smiley 1996. While individual variations in growth may exist, the overall shared growth pattern reflects the environmental signal.…”

“…Trees record in the density, width, structure, and chemical composition of their annual rings information about both biotic and abiotic processes in the surrounding environment. Since A. E. Douglas's 1920 publication (1) in Ecology, in which he documented the relationship between tree ring width and precipitation, the field of dendrochronology (i.e., the study of tree rings referenced in time) has expanded into a variety of subdisciplines including dendroecology, dendroclimatology, and dendropyrochronology, to name only a few (2)(3)(4). Yet, as each of these disciplines has greatly expanded our understanding of long-term processes, there remain several key issues that must be addressed as we seek to refine and expand this data-rich resource.…”

Herbivory, plant resistance, and climate in the tree ring record: Interactions distort climatic reconstructions

To understand climate change, dendrochronologists have used tree ring analyses to reconstruct past climates, as well as ecological processes such as herbivore population dynamics. Such reconstructions, however, have been hindered by a lack of experiments that separate the influences of confounding impacts on tree rings, such as herbivores and the interactions of multiple factors. Our longterm experiments with scale insects on resistant and susceptible pines demonstrate three major points that are important to the application of this commonly used tool. (i) Herbivory reduced tree ring growth by 25-35%. (ii) The impact on ring growth distorted climate reconstruction, resulting in the overestimation of past moisture levels by more than 2-fold. Our data suggest that, if distortion because of herbivory has been a problem in previous reconstructions, estimates of the magnitude of recent climate changes are likely to be conservative. (iii) Our studies support a detectible plant resistance ؋ herbivore ؋ climate interaction in the tree ring record. Because resistance and susceptibility to herbivory are known to be genetically based in many systems, the potential exists to incorporate plant genetics into the field of dendrochronology, where it may be used to screen distortions from the tree ring record.
