Dendrochronology: Fundamentals and Innovations

چکیده
Abstract This chapter overviews long-standing foundations, methods, and concepts of dendrochronology, yet also pays attention to a few related paradigm shifts driven by isotope measurements in tree-rings. The basics annual ring formation are first reviewed, followed structural descriptions tree-rings at the macroscopic-to-microscopic scale including earlywoodandlatewoodin conifers (gymnosperms) hardwoods (angiosperms), as well wood anatomical features. Numerous examples inter-disciplinary applications connected various tree-ring parameters provided. With foundation established, this then describes process necessity for crossdating—the which each every is assigned specific year. Methods terminology field sampling briefly described. site selection criteria—well shown maximize common signals width datasets—is challenged brief discussion newer literature demonstrating that robust chronologies with high signal-to-noise ratios can be obtained non-ecotonal locations. Opportunities enable crossdating otherwise challenging contexts likewise highlighted. reviews conceptual framework disaggregate time-series, special detrending standardization methods used mitigate tree-age/size noise many such dendroclimatic reconstruction. Some drivers long-term trends data increase atmospheric concentration CO 2 , age/size/height trends, climate variation presented along debates/uncertainties evident order establish priorities future investigations. development quality control metrics assess signal variance described, limitations correlation based statistics determine robustness datasets particularly low frequency domain. These statistical will gain relevance increasingly approach sample replications dataset structures typical measurements.

Dendrochronology and Geochemistry of Long Island Trees
To help understand the effect of short term climatic changes on ring width variations of trees on Long Island, time series were performed on 6 Liriondendrin tuliperfera (tulip poplars) and 1 white oak from Caumsett State Park, and 6 Pinus rigidas (pitch pines) from Sears Bellows and Hubbard County Parks. Prolonged drought periods on Long Island occur during years 1927-1932, 1960-1970 and 1980-1...
متن کاملClimate from dendrochronology: latest developments and results
This review deals with the latest developments in dendroclimatology focused on climate reconstruction. It presents results from research carried out during the period 1992–2001, when both the geographical and chronological extension of tree-ring data were greatly improved. Research projects are presently being carried out in nearly all the main forest land areas of the Subarctic and Subantarcti...
متن کاملWeb-Based Tools for Teaching Dendrochronology
This article describes two web-based tools for teaching dendrochronology, the scientific study of tree rings, and presents quantitative evaluations of their value in a large class. Because of its wide scientific applicability, dendrochronology is appropriate for teaching in a wide array of courses, including those in the fields of natural resources and life sciences. Until recently, professors ...

In 1977, the United States Department of Agriculture and the Canadian Department of the Environment agreed to cooperate in an expanded and accelerated research and development effort, the Canada /United States Spruce Budworms Program (CANUSA), aimed at the spruce budworm in the East and the western spruce budworm in the West. The objective of CAN USA was to design and evaluate strategies for co...
