Texas horned lizard (Phrynosoma cornutum) populations have been in steady decline over the past twenty years due to habitat loss, pesticide use, the pet trade, and invasion of the red imported fire ant (Solenopsis invicta). At Aransas National...
The Codell Sandstone Member of the Carlile Shale is located in the northwest quarter of Kansas. As a source of groundwater, it is most frequently utilized in Ellis, Trego, Rooks, Graham, Gove and Logan counties. The aquifer is characterized by two...
In preparing for a trip to Mexico in 1983 and writing a paper about Pre-Columbian art, I discovered an art that was mysterious, spiritual, yet possessed an honesty I admired. The Pre-Columbian approach to art can best be felt in these lines from an...
The plains pocket mouse (Perognathus flavescens) is one of the most abundant species of mammal in agriculturally disturbed areas of the Sandsage Prairie of southwestern Kansas. Plains pocket mice are active above ground from early spring until late...
The distributions and numerical status of the three species of foxes in Kansas have changed appreciably in the past century. Undocumented information suggests the red fox was common in parts of western Kansas, and therefore probably occurred...
An automatic camera device, live-traps, and direct observations under red light were utilized in obtaining information on a woodrat population. Activity periods, movements, behavioral mannerisms, and ecological aspects were recorded.
Woodrats were...
