    • AN INVESTIGATION OF FOUR RARE SNAKES IN SOUTH-CENTRAL KANSAS •• ·: ' ·- .. ··... LARRY MILLER 15 July 1987 • . -· • AN INVESTIGATION --OF ----FOUR ----RARE SNAKES IN SOUTH-CENTRAL KANSAS BY LARRY MILLER INTRODUCTION The New Mexico blind snake (Leptotyphlops dulcis dissectus), Texas night snake (Hypsiglena torqua jani), Texas longnose snake (Rhinocheilus lecontei tessellatus), and checkered garter snake (Thamnophis marcianus marcianus) are four Kansas snakes with a rather limited range in the state. Three of the four have only been found along the southern counties. Only the Texas longnose snake has been found north of the southern most Kansas counties. This project was designed to find out more about the range, habits, and population of these four species of snakes in Kansas. It called for a search of background information on each snake, the collection of new specimens, photographs of habitat, and the taking of notes in regard to the animals. The 24 Kansas counties covered in the investigation ranged from Cowley at the southeastern most • location to Morton at the southwestern most location to Hamilton, Kearny, Finney, and Hodgeman to the north. Most of the work centered around the Red Hills area and to the east of that area. See (Fig. 1) for counties covered. Most of the work on this project was done by me (Larry Miller). However, I was often assisted in the field by a number of other persons. They will be credited at the end of this report. METHODS A total of 19 trips were made by me between the dates of 28 March 1986 and 1 July 1987 in regard to this project.

  • Ventral Coloration and Body Condition Do Not Affect Territorial Behavior in Two Sceloporus Lizards
    Ventral coloration and body condition do not affect territorial behavior in two Sceloporus lizards 1Marina Kelada, 1Courtney Moulton, 2Casey Nguyen, 3Griselda Robles Olague 1University of California, Riverside; 2University of California, Irvine; 3University of California, Santa Barbara Sceloporus lizards are known to be defensive of their territories, which provide shelter, food, water, and mates. They often exhibit territorial behavior through visual displays of aggression, specifically with pushups. Along with aggression, this display can also expose the blue coloration on their ventral side, serving as an intraspecific communication between lizards that reveals information about their dominance, sex, and species membership. In this study, we compared how blue coloration and body condition affected territorial behavior in two Sceloporus lizards: the well-studied western fence (Sceloporus occidentalis) and the understudied sagebrush (Sceloporus graciosus), two closely related lizards with overlapping ranges in the San Jacinto Mountains. We also addressed whether these species would exhibit character displacement in their ventral coloration as a result of their sympatry. ImageJ and Adobe Photoshop were used for photo analyses to quantify the proportion and intensity of blue on each lizard’s ventral side. Territoriality was measured through number of pushups displayed and distance traveled. We found that both ventral coloration and body condition had no effect on the territoriality of either species, suggesting that territorial behavior
