【摘要】 Burrow structural charactersitcs and microhabitat use of the Turpan wonder gecko Teratoscincus roborowskii(Gekkonidae) were studied between April and September of 2013 in the Turpan Eremophytes Botanic Garden,in the Turpan Depression of Western China.Burrow depth,entrance orientation,entrance height and width were observed.We assessed microhabitat selection and noted differences in microhabitat use among males,females,and juveniles.The magnitude of selection was measured using Jacobs’ index of selectivity.Entrance height and width of the burrows of adults were significantly larger than those of juveniles,but the difference in burrow depth was not significant.The directional orientation of the burrow entrance showed a preference for the north-northeast and south-southeast,which were likely influenced by local prevailing winds and sunlight.Both the adult and juvenile geckos prefer to construct their burrows in sandy soil within a layer of loose soil whose thickness is greater than 30 cm.A majority of the burrows were located within 20 m of the nearest plant.Nearly half(48%) of the entrances of juveniles were located within 5 m of the nearest vegetation,significantly different from those of the adults.Results showed that the Turpan wonder gecko did not utilize microhabitats according to their availability,but rather that it preferred microhabitats which contained dead wood or the caper bush.Our results suggested that burrow characteristics and microhabitat selection were important factors in T.roborowskii adaptation to harsh and arid desert habitats.
