New correlation of stable carbon isotopes with changing late-Holocene fluvial environments in the Trinity River basin of Texas, USA
Open AccessStephen A Hall, Thomas W Boutton et al.ARTICLEThe Holocene2011Referências: 8
A late-Holocene alluvial sequence in north-central Texas has a 1 m thick buried cumulic soil with an A-C profile called the West Fork paleosol. It formed 2300 to 1000 yr BP and is a local equivalent of the Copan paleosol that is present throughout the southern US Great Plains. Stable carbon isotopes indicate that the paleosol and underlying gray clay formed under vegetation dominated by C 4 species (mean δ 13 C: −18.3 ± 0.3‰). Diverse paleoenviro…
C 4 Plant Productivity and Climate-CO 2 Variations in South-Central Texas during the Late Quaternary
Open AccessLee C Nordt, Thomas W Boutton et al.ARTICLEQuaternary Research2002
A continuous record of organic carbon δ 13 C from a buried soil sequence in south-central Texas demonstrates: 1) strong coupling between marine and adjacent continental ecosystems in the late Pleistocene as a result of glacial meltwater entering the Gulf of Mexico and 2) ecosystem decoupling in the Holocene associated with a reduction of meltwater and a shift in global circulation patterns. In the late Pleistocene, reduction in C 4 plant producti…

Natural Abundances of Carbon Isotopes ( 14 C, 13 C) in Lichens and Calcium Oxalate Pruina
Open AccessMelanie J Beazley, Richard D Rickman et al.ARTICLERadiocarbon2002Citada por: 5Referências: 30
Radiocarbon ages of calcium oxalate that occurs naturally on rock surfaces have been used recently in archaeological and paleoenvironmental studies. Oxalate rock coatings are found globally, with most appearing to be residues from epilithic lichens. To explore the source(s) of carbon used by these organisms for the production of oxalate we measured the natural abundances of 14 C and 13 C in 5 oxalate-producing lichen species, 3 growing on limesto…

Origin of the Whewellite-Rich Rock Crust in the Lower Pecos Region of Southwest Texas and Its Significance to Paleoclimate Reconstructions
Open AccessJon Russ, Russell L Palma et al.ARTICLEQuaternary Research1996
A calcium oxalate (whewellite)-rich crust occurs on exposed limestone surfaces in dry rock and open air shelters in the Lower Pecos region of southwest Texas. The crust, which also contains gypsum and clay, formed over silica-rich limestone during the Holocene. SEM and optical photomicrographs reveal similarities between whewellite microstructures and the lichen Aspicilia calcarea. This desert lichen is known to produce calcium oxalate, and has b…
Late Quaternary Vegetation and Climate Changes in Central Texas Based on the Isotopic Composition of Organic Carbon
Open AccessLee C Nordt, Thomas W Boutton et al.ARTICLEQuaternary Research1994
Stable carbon isotope analysis of organic carbon in alluvial deposits and soils of three streams in central Texas reveals significant shifts in the ratio of C 3 to C 4 plant biomass production during the past 15,000 yr. These temporal changes in vegetation appear to be in response to changes in climate. During the late Pleistocene, C 4 plants comprised only about 45 to 50% of the vegetative biomass in this area, suggesting that conditions were co…
Recognizing Women in the Archeological Record
Open AccessM Pamela Bumsted, Jane E Booker et al.ARTICLEArcheological Papers of the…1990Referências: 18
Primary sexual characteristics are usually absent in the archeological record. The recovered secondary sex markers in bone morphology or mortuary context reflect the lifelong integrated biocultural experience of the individual man or woman. Internal patterns of variability within and between sexes can be recognized but are too frequently masked by traditional descriptive and univariate analyses. Fortunately, a detailed picture of life experience …
Stable Carbon Isotopic Evidence for Maize Agriculture in Southeast Missouri and Northeast Arkansas
Open AccessMark J Lynott, Thomas W Boutton et al.ARTICLEAmerican Antiquity1986Citada por: 23Referências: 20
Analysis of bone collagen extracted from human skeletal remains from archaeological sites dating from the Archaic period through Euro-American settlement provides evidence for the introduction of maize into regional subsistence patterns. Stable carbon isotope ratios of samples from both the eastern Ozarks and the Mississippi River alluvial valley indicate that human populations living prior to ca. A.D. 1000 consumed little or no C4 plant material…
