| 英文摘要 | The flat-tailed horned lizard (Phrynosoma mcallii) occupies a restricted range in the Lower Sonoran Desert of southwest Arizona, southeast California, and adjacent land in Mexico. Because they exhibit behavior patterns that include basking and remaining motionless when danger approaches, flat-tailed horned lizards are particularly susceptible to mortality on roads. Therefore, roads and new road construction are recognized as threats influencing the long-term persistence of this species. The propensity for flat-tailed horned lizards to use culverts as road crossing structures to avoid vehicle-caused mortality is unknown. From 2005-2006 we studied flat-tailed horned lizard use of a variety of simulated road crossing structures. The study objectives were to (1) determine if flat-tailed horned lizards will pass through culverts of sizes commonly used in road construction, and (2) compare and describe the characteristics of culverts used by flat-tailed horned lizards to those not used. We built a testing facility with six culverts of three dimensions and two interior lighting options. |
