Testing the Hotspot Hypothesis: Lesser Prairie-Chickens Lek Formation and Female Space Use
Underlying mechanisms causing the formation of lesser prairie-chicken (Tympanuchus pallidicinctus) leks have both evolutionary and management implications. Surveys of leks are the principle method to monitor population trends due to year around site fidelity of males to a lek. Management of lesser prairie-chickens relies on the assumption that leks form under the hotspot hypothesis, which states that leks form in areas where female home ranges touch or overlap in high quality breeding habitat. However, this assumption has not been tested, nor have other competitive hypotheses regarding the formation of lesser prairie-chicken leks been tested with empirical data. We tested the hotspot hypothesis using estimated home ranges for female lesser prairie-chickens and known leks in Kansas and Colorado. We combined female home ranges in our study area and created a resource utilization function raster of intensity of use and modeled the intensity of use as a function of distance from a lek. We compared distances of the centroid of female home ranges and centroids of random placement of average homes on the landscape to determine if home ranges are closer to a lek than expected at random. Preliminary results indicate that lek locations were related to concentrations of female home ranges.
