Henri D.Grissino-Mayer's Ultimate Tree-Ring Web Pages
This clearinghouse offers various means by which users can access information and resources on dendrochronology and such associated fields as paleoclimatology, plant anatomy, palynology, systematics, taxonomy, cladistics, and the study of permineralized plants and petrified forests. The most basic method is by way of the Contents page, which alphabetically combines those items, concepts, keywords, and phrases of interest addressed by the clearinghouse nodes. An alternate approach, under Resources, is intended primarily for use by dendrochronologists and contains material on conferences and workshops, tree-ring, climate, and paleoclimatic data, references about tree-rings, and educational resources for teachers. The Links page contains connections to major laboratories at academic institutions, additional tree-ring research sites, published tree-ring research abstracts, abstracts of National Science Foundation (NSF) funded tree-ring research, and personal home pages of tree-ring enthusiasts. The Software page leads to sites including ftp sites where dendrochronologists can download and/or purchase programs useful in their discipline. The Principles of Dendrochronology pages include definitions of key terms in the discipline, followed by explanations of the Uniformitarian Principle and the Principles of Limiting Factors, Aggregate Tree Growth, Ecological Amplitude, Site Selection, Crossdating, and Replication. The References page is categorized according to such specific interests as dendropyrochronology and dendroglacialogy. Also available are links to various Databases, Supplies for dendrochronologists, a gallery of photographs, a FAQ page, a What's New section covering the latest developments and announcements in the field, and a search engine specific to the site. Notably, the author has provided either an annotation or review for every link included on the site.
