Captive observations on reproduction of the Peak Tree Iguana, Liolaemus monticola (Squamata: Liolaemidae), an endemic species of Chile

Abstract

Liolaemus is a diverse genus of South American lizards whose reproductive biology remains poorly known in several species. We describe reproductive aspects of Liolaemus monticola, an endemic Chilean species, based on two gravid females that laid eggs in captivity. Both females produced four eggs, with different hatching success. The incubation period lasted 52–58 days. Measurements of size, mass, growth rate, and body mass index of hatchlings are reported. These data provide relevant information for future conservation actions.
