ABSTRACT We have conducted radiocarbon ( 14 C) dating of Japanese tree rings from 1053 to 921 BCE and 41 130 CE. Dating was also performed using oxygen isotope dendrochronology investigate subtle structures the calibration curve corresponding beginning end Yayoi period in Japan. These two results followed IntCal20, which included C ages Japan-sourced trees. The findings suggest that specimens o...

The longleaf pine ( Pinus palustris Mill.) and related ecosystem is an icon of the southeastern United States (US). Once covering estimated 37 million ha from Texas to Florida Virginia, near-extirpation of, subsequent restoration efforts for, species has been well-documented over past ca. 100 years. Although one longest-lived tree in US—with documented ages 400 years—its use not reviewed field ...

The need to understand natural climate variability and improve weather forecasts gave birth the first tree-ring reconstructions more than a century ago in Europe North America, still defines central motivation for modern paleoclimatology: learning from past prepare future.
