Age-related variation in lipophilic chemical compounds from femoral gland secretions of male lizards Psammodromus algirus
چکیده انگلیسی

In spite of the importance of chemoreception in social organization of lizards, only a few studies have examined chemical composition of secretions of lizards. The secretion of the femoral glands of male lizards Psammodromus algirus contains 59 lipophilic compounds, mainly carboxylic acids between n-C9 and n-C20, and steroids (mainly campesterol, ergosterol and cholesterol), and minor components such as five alcohols, six aldehydes, squalene, α-tocopherol, ketones, and a furanone. These compounds were identified on the basis of mass spectra, obtained by GC–MS. Secretions of adult males of different age were different. Older lizards had secretions with relatively lower proportions of octadecadienoic, oleic and eicosatetraenoic acids, and higher proportions of campesterol, ergosterol, ergostenol, 4,4-dimethy-cholest-7-en-3-ol, and ergosta-5,22-dien-3-ol. These differences might allow conspecifics to get information on the age of the sender based on chemicals alone, which may have an important role in social behavior of this lizard.
