AGGREGATION OF SCELOPORUS MINOR (SAURIA: PHRYNOSOMATIDAE) FROM CERRO EL POTOSi, NUEVO LEON, MEXICO

摘要

We report for the first time aggregation behavior in the lizard Sceloponis minor. The behavior was recorded at Galeana, Nuevo Leon, Mexico, where a group of ca. 30 individuals were observed under a rock associated with a stone wall. Weight, sex, snout-vent length, and total length were recorded for 22 individuals. Means of traits were: males-weight = 18.9 g, snout-vent length = 80.5 mm, total length = 173.3 mm; females-weight = 13.9 g, snout-vent length = 72.9 mm, total length = 161.1 mm. Sex ratio was 16 males:6 females. Our observation extends the known elevaticmal range of the species from ca. 3,000 in to 3,470 m.
