Abstract: Fossorial and nocturnal lizards have limited opportunities to thermoregulate because they do not have access to basking opportunities, which has implications for their thermal physiology and metabolism. We measured substrate temperatures (Ts) in the field, and selected body temperatures (Tb) and metabolic rates in the laboratory, in fossorial skinks, Saiphos equalis, to quantify basic aspects of their thermal and metabolic physiology. Saiphos equalis selects relatively cool temperatures over a broad range (approximately 17–24 °C), suggesting that it does not thermoregulate precisely. Individuals of S. equalis are active more often at night than during the day. Rate of oxygen consumption was measured at 2 °C intervals from 10–30 °C in adult lizards. Metabolic rate increased as a function of temperature but there was no significant difference in VO2 over the preferred temperature range. Like many other fossorial lizards, S. equalis is nocturnal and selects relatively low body temperatures compared to heliothermic lizard species.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
