University of Texas at Arlington biologists are studying a species of lizard found in parts of Texas and northeastern Mexico to find out why the reptile's numbers have been dwindling dramatically.
They are conducting fieldwork and genome sequencing to learn as much as possible about the spot-tailed earless lizard Holbrookia lacerata, which has experienced a steady decline in population in Central and South Texas. The work is being supported by a two-year grant from the Texas Parks & Wildlife Department.
"We are carrying out a comprehensive study of the natural history, morphology, phylogenetics and ecological genetics of H. lacerata to provide a thorough assessment on the conservation and management priorities for this imperiled species," said Corey Roelke, a College of Science biology lecturer and principal investigator of the project.
"While the factors causing the lizard's dwindling numbers are unknown, at least some of the decline is likely due to anthropogenic - meaning caused by human activity - habitat change," Roelke added. "Potential threats include the use of agricultural herbicides and insecticides; loss of habitat and habitat fragmentation due to conversion of land to agriculture use or road construction."
