A recent study from Verble Fire Ecology Lab examined how prescribed burning influenced the home range size of Texas horned lizards in central Texas. The study also examined how fires and drought influenced nutritional quality, abundance, and density of the primary prey item of the lizard. The researchers modeled how these factors influenced lizard survival. Fires changed the vegetation of the area in a predictable way. Fires impacted horned lizard survival, but differentially between sexes. Finally, fires changed the nutritional quality of the ants, but not in the way one might think. These data will help guide future habitat management and restoration efforts.
Robin Verble-Pearson, Ph.D., discussed the study in a webinar on September 8, 2015. The webinar recording can be viewed below.
