A vital component of dendroclimatology is the validation of reconstructions. Given the scant instrumental data prior to the 20th century, the validation of dendroclimatological reconstructions largely depends on other proxy-inferred climate reconstructions. Here we compare a three-century tree-ring inferred central Minnesota moisture reconstruction based upon sites in Minnesota (e.g. Itasca Park) ... More

In a closed-canopy forest, stand dynamics play an important role in shaping the forest, and it has been hypothesized that dense forests are not sufficiently limited by climate to warrant climate reconstruction. We sample Quercus prinus ring-widths from a dense forest in the Appalachians, and after removal of stand dynamics and age trends we find strong correlations between the developed chronology ... More

Tree-rings play an important role in reconstructing past temperature in high-latitude and high-elevation regions. However, little tree-ring research has been done in the subtropical southeastern China. Recent studies show that coniferous tree growth there is limited by temperatures in prior winter and the current growing season. Higher temperature in the dormant season means less damage to leaves ... More

Spatial modes of tree-growth in a newly developed network of 78 chronologies are summarized by S-mode principal components analysis (PCA), using varimax rotation of components. The network, representing eleven species and five countries, is intended for climatic reconstruction. Runs of PCA on two periods are described: 1) 1923-2000 CE (common period for all 78 chronologies), 2) 1251-2000 CE (tim ... More

We reconstructed tupelo honey yield-per-hive from 1800–2010 using tree-ring data from the nectar-source species, Nyssa ogeche. The composite N. ogeche radial growth chronology and honey yield-per-hive were significantly correlated, suggesting optimal growth conditions are coincident with increased nectar production and that tree-ring data can be used to reconstruct crop history. Tupelo honey yi ... More
