Abstract: Lizards possess epidermal glands which produce secretions playing a role as semiochemicals. Classic anatomical studies do not give detailed information on the nature of the secretions. Here I used GC-MS analysis of gland secretions to focus on the molecular structure of femoral gland secretions in two xeric-adapted agamid lizards, Uromastyx aegyptia and U. ornata. Steroids, alcohols, carboxylic acids, alkanes, aldehydes, carboxylic acid esters and squalene were detected as lipidic compounds. Monoglycerides of fatty acids and glycerol monoethers of long chain alcohols previously only detected in Lacertidae and Gekkonidae were also identified. The compounds constituting femoral secretions are possibly an adaptation to hot and dry habitats, with specific chemical profiles for each species. The presented data support the hypothesis that Uromastyx (and lizards in general) use femoral gland secretions for chemical communication.

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.
