Tropical and subtropical forests cover only 7 % of the Earth’s land surface. Yet, they host nearly half global tree density with a high species number (∼40,000 species), store up to 25 terrestrial carbon represent one-third net primary productivity on Earth. Over last four decades, study growth in tropics has gained substantial momentum, not least because increasing application tropical climato...

The Tellervo dendrochronological software builds upon the Tree-Ring Data Standard (TRiDaS) to provide a tool for recording and managing all manner of dendrochronological data. However, Tellervo is especially useful for dendroarchaeological research. The traditional file formats used in dendrochronology—and by association the applications that use them—have very limited and nonstandard methods f...

Investigation of tree growth in Isle Royale National Park in Michigan revealed the influence of herbivores and carnivores on plants in an intimately linked food chain. Plant growth rates were regulated by cycles in animal density and responded to annual changes in primary productivity only when released from herbivory by wolf predation. Isle Royale's dendrochronology complements a rich literatu...

In order to establish an estimate of the ages of large Pacific madrone (Arbutus menziesii) trees growing atop the bluffs on Magnolia Boulevard in Seattle, Washington, I obtained stump-discs from madrones cut by the Seattle Parks Department in June 1994. Each disc was sectioned into smaller pieces to allow processing with standard woodworking techniques. After initial processing, each slab was s...
