Archaeological Investigations and Oxidizable Carbon Ratio Dates from 41RK476, Rusk County, Texas

Hays County, Texas

The widespread Berberis trifoliolata is sympatric with the narrowly restricted B. swaseyi in central Texas, where apparent intermediates occur. A detailed field study of sympatric populations in northern Hays Co. during 2004 to 2007 clarifies the morphological and phenological differences between the two species and shows that intermediates almost surely arose from hybridization. Limited eviden...

Le Morne Cemetery: Archaeological Investigations

Insects and associated arthropods analyzed during medicolegal death investigations in Harris County, Texas, USA: January 2013- April 2016

The application of insect and arthropod information to medicolegal death investigations is one of the more exacting applications of entomology. Historically limited to homicide investigations, the integration of full time forensic entomology services to the medical examiner's office in Harris County has opened up the opportunity to apply entomology to a wide variety of manner of death classific...

Prehistoric peyote use: alkaloid analysis and radiocarbon dating of archaeological specimens of Lophophora from Texas.

Two archaeological specimens of peyote buttons, i.e. dried tops of the cactus Lophophora williamsii (Lem.) Coulter, from the collection of the Witte Museum in San Antonio, was subjected to radiocarbon dating and alkaloid analysis. The samples were presumably found in Shumla Cave No. 5 on the Rio Grande, Texas. Radiocarbon dating shows that the calibrated 14C age of the weighted mean of the two ...

Linking Preterm Birth and Air Pollution in Harris County, Texas

Exposure to high levels of air pollution has many known adverse health effects including heart and lung disease. Associations between exposure and increased mortality have also been estimated. The link between exposures to pollutants, such as particulate matter 2.5 micrometers and smaller (PM2.5 ) and ozone, and birth outcomes is not as well established because of the lack of quality data. We d...
