Evaluating possible sources of error in tree-ring 14C data using multiple trees across South America
A limitation in fine-tuned tree-ring radiocarbon ( 14 C) data is normally associated with overall data uncertainty. Tree-ring 14 C data variance as a result of sample heterogeneity can be reduced by adopting best practices at the time of sample collection and subsequent preparation and analysis. Variance-reduction of 14 C data was achieved by meticulous sample handling during increment core or cross-sectional cuttings, in-laboratory wood reductio…
Pan American interactions of Amazon precipitation, streamflow, and tree growth extremes
Rainfall and river levels in the Amazon are associated with significant precipitation anomalies of opposite sign in temperate North and South America, which is the dominant mode of precipitation variability in the Americas that often arises during extremes of the El Niño/Southern Oscillation (ENSO). This co-variability of precipitation extremes across the Americas is imprinted on tree growth and is detected when new tree-ring chronologies from th…
Meteorological Factors Associated With Frost Rings in Rocky Mountain Bristlecone Pine at Mt. Goliath, Colorado
The meteorological factors involved in the formation of earlywood frost rings in Rocky Mountain bristlecone pine (Pinus aristata) have not been described in detail. This study used 51 tree-ring dated Rocky Mountain bristlecone pine trees growing at ca. 3500 m a.s.l. on Mt. Goliath, Colorado, to develop earlywood and latewood frost ring chronologies dating from 1930 to 2010 for investigation of the regional and large-scale weather anomalies respon…
The Climate Response of Cedrela Fissilis Annual Ring Width in the Rio São Francisco Basin, Brazil
The São Francisco River basin is one of the most drought-prone regions of Brazil. Seasonally dry tropical forests (SDTF) are widely distributed in the basin and we developed a short chronology of Cedrela fissilis annual ring widths from SDTF fragments based on 89 cores from 44 trees dating from 1961 to 2015. The average correlation among all radii (RBAR) is 0.52. The tree-ring chronology is correlated with wet season precipitation totals, must st…
