Femoral gland secretions were collected from 21 captive adult male green iguanas (Iguana iguana) in Orotina, Costa Rica, and San Diego, California, during the breeding (November) and nonbreeding (March) seasons. Lipids were extracted with methylene chloride, weighed, separated by thin-layer chromatography, and analyzed by gas chromatography-mass spectrometry. Free and esterified C14-C26 fatty acids, 5β-cholestan-3α-ol (epico-prostanol), cholest-5-en-3β-ol (cholesterol), cholest-5-en-24-methyl-3… 

Chemical Compounds from the Preanal Gland Secretions of the Male Tree Agama (Acanthocercus atricollis) (Fam. Agamidae)

This work found 60 lipophilic compounds in preanal gland secretions of the male tree agama (Acanthocercus atricollis) (fam. Agamidae), including steroids, fatty acids, ketones, and other minor compounds, which are compared with those present in other lizard species and discussed their potential function in social behaviour.

Characterization of lipid structures in femoral secretions of Galápagos marine iguanas by shotgun lipidomics

This study is the first to use a lipidomics-based approach to characterize lipid composition in lizard femoral secretions and shed new light on the potential function of lipids in intraspecific chemical communication.

Chemical characterization of the lipids in femoral gland secretions of wild male tegu lizards, Salvator merianae (Squamata, Teiidae) in comparison with captive-bred males

Within-species differences between wild and captive lizards strongly suggest the important influence of different diets on the chemical composition of the femoral gland secretion and suggest caution when interpreting results from captive animals, even in the same species.

Chemical Constituents of the Femoral Gland Secretions of Male Tegu Lizards (Tupinambis merianae) (Family Teiidae)

49 lipophilic compounds in femoral gland secretions of male tegu lizards (Tupinambis merianae) (fam. Teiidae) are found, including a very high proportion of carboxylic acids and their esters ranging between n-C8 andN-C20 (mainly octadecanoic and 9,12-octadecadienoic acids), and the potential function of these compounds in secretions is discussed.

Lipids in the Femoral Gland Secretions of Male Schreiber’s Green Lizards, Lacerta schreiberi

The secretion of the femoral glands of male Schreiber’s green lizards (Lacerta schreiberi) contains 51 lipophilic compounds, including several steroids, α-tocopherol, n-C9 ton-C22 carboxylic acids and their esteres, and minor components such as alcohols between C12 and C24, two lactones, two ketones, and squalene.

Intersexual Differences in Chemical Composition of Precloacal Gland Secretions of the Amphisbaenian Blanus cinereus

The abundance of steroids and waxy esters in secretions of both male and female amphisbaenians may be useful to scent mark underground tunnels to facilitate orientation by these organisms.

Field and laboratory studies suggest that femoral gland secretions function in conspecific recognition and range marking in desert iguanas and green iguana, and may reflect adaptations to the diverse climatic conditions of arid desert and tropical forest environments.

Chemical properties of femoral gland secretions in the desert iguana,Dipsosaurus dorsalis

Investigation of the chemistry of femoral gland secretions in the desert iguana, dipsosaurus dorsalis, finds that they strongly absorb longwave ultraviolet light, a feature that may be important in the localization of secretion deposits in the environment.

Reproductive cycles, fat body cycles and socio-sexual behaviour in the Mallee dragon, Amphibolurus fordi (Lacertilia : Agamidae)

The development of the gonads, including the histology of the testicular cycle, is described, together with correlated changes in the size of the inguinal fat bodies in the small agamid lizard Amphibolurus fordi.

The mating behavior of Iguana iguana

It is hypothesized that the ecological factors responsible for the unusual mating system are related to the lack of defendable resources, the iguana's folivory, and the high density of iguanas present in preferred mating areas.

Hormonal Control of Mammalian Skin Glands

The endocrine control of several species has been studied; previous reviews include those of Ebling and Strauss and Ebling (1970).

Rapid Direct Extraction Derivatization Method for the Determination of Acylglycerol Lipids in Selected Sample Matrices

Acylglycerol lipids as total fatty acid methylesters (FAME) were rapidly determined by direct extraction derivatization from sample matrices utilizing 0.4N methanolic sodium methoxide in hexane
