Neonatal growth of three species of Xenosaurus (Squamata: Xenosauridae) in captivity

Abstract

Lizards of the genus Xenosaurus W. Peters, 1861 are mostly crevice-or hole-dwellers, and found in cloud forest, tropical forest, pine-oak forest and xerophytic scrub in the mountains of eastern and southern Mexico (reviewed in Ballinger et al. 2000, Lemos-Espinal et al. 2012). Their conservation status is somewhat variable because of the six species of Xenosaurus evaluated in the IUCN Red List, two are endangered (X.

“…Growth rates of Xenosaurus grandis in Veracruz were apparently affected by prey availability and environmental temperatures (Zúñiga‐Vega et al, 2005). Finally, growth rates of neonates in the laboratory differed among three species of Xenosaurus ( X. grandis , X. fractus , and X. rectocollaris ; Woolrich‐Piña et al, 2019) suggesting potential genetic variation in individual growth rates, at least among species.…”
