Web-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 ...
متن کاملDendrochronology 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 کاملUsing Dendrochronology To Measure Radial Growth
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...
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 کاملDendrochronology: a Review with Emphasis on New Zealand Applications
The distinction is drawn in this paper between true dendrochronological studies (using crossdating) and studies using tree-ring counts to age trees or date events. The advantages of the former approach are emphasized. We summarize the main methods used in dendrochronology, concentrating on new approaches and techniques important in the New Zealand context, present a review of recent dendrochron...
