Archaeological Testing at Two Well Locations in New Braunfels, Comal County, Texas

Two-year survey comparing earthquake activity and injection-well locations in the Barnett Shale, Texas.

Between November 2009 and September 2011, temporary seismographs deployed under the EarthScope USArray program were situated on a 70-km grid covering the Barnett Shale in Texas, recording data that allowed sensing and locating regional earthquakes with magnitudes 1.5 and larger. I analyzed these data and located 67 earthquakes, more than eight times as many as reported by the National Earthquak...

Distribution of Juniperus Ashei Var. Ashei and Var. Ovata around New Braunfels, Texas

The distribution of J. ashei var. ashei and J. a. var. ovata was examined by leaf essential oils. The populational boundries between these varieties seems to be very distinct. However, there appears to be some intergradation between the two taxa near New Braunfels, Texas.

Geophysical Survey at archaeological site Kaszaper, Békés County, Hungary

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...
