“…Multiple pheromone compounds in femoral gland secretions seem to inform about the characteristics and health state of a male Martín et al, 2007a). This information may be used by females to select scent marks of some individual males, which suggests pheromonal mate choice (e.g., López, 2000, 2006a;López et al, 2002López et al, , 2003Olsson et al, 2003;López and Martín, 2005a). Compounds in femoral gland secretions may also provide information on fi ghting ability or dominance status to other males (Aragón et al, 2001;Carazo et al, 2007;Martín et al, 2007b).…”

In spite of the importance of chemical signals (pheromones) in the reproductive behaviour of lizards, the chemical compounds secreted by their femoral glands, which may be used as sexual signals, are only known for a few lizard species. Based on mass spectra, obtained by GC-MS, we found 49 lipophilic compounds in femoral gland secretions of male tegu lizards (Tupinambis merianae) (fam. Teiidae), including a very high proportion of carboxylic acids and their esters ranging between n-C 8 and n-C 20 (mainly octadecanoic and 9,12-octadecadienoic acids), with much less proportions of steroids, tocopherol, aldehydes, and squalene. We discuss the potential function of these compounds in secretions, and compare the compounds found here with those documented for other lizard species.

“…Female choice favoured larger palae, whereas male competition favoured smaller palae, probably owing to costs to males of large palae. Whether the two forces, female choice and male competition, act in the same or opposite direction is currently debated, with differing results for different species (Berglund et al 1996;Wiley & Poston 1996;Qvarnströ m & Forsgren 1998;Candolin 1999;Moore & Moore 1999;Wollerman 1999;Andersson et al 2002;Lopez et al 2002). In the present species, enforcing or counteracting female choice and male competition depend on whether individuals vary in their ability to cope with both juvenile and adult conditions.…”

“…Of particular importance is the third possibility, that different traits are used in female mate choice and in male-male competition. These two selection pressures can work in concert or be in conflict, which could influence the maintenance of genetic variation of traits (Qvarnströ m & Forsgren 1998;Moore & Moore 1999;Andersson et al 2002;Lopez et al 2002). For example, traits that are favoured in male competition may correlate negatively with male parental effort and be counteracted by female choice for direct benefits (Smith 1995;Forsgren 1997;Qvarnström 1997;Magrath & Komdeur 2003).…”

Why do multiple traits determine mating success? Differential use in female choice and male competition in a water boatman

Mating success is often determined by multiple traits, but why this occurs is largely unknown. Much attention has been paid to female preferences for multiple traits, but surprisingly few researchers have addressed the possibility that multiple traits are important because they serve different functions in female choice and male-male competition. Differential trait function could result from a conflict of interest between the sexes or from constraints forcing the sexes to pay attention to different traits. I show that traits determined at distinct life-history stages differ in their importance in female choice and male-male competition in a water boatman Sigara falleni. Juvenile conditions determined body and foreleg pala size and were the main determinants of mating success under female choice, whereas adult conditions determined body mass and influenced mating success when male competition was included. This differential use of condition-dependent traits under the two selection regimes appeared to arise partly from a conflict between the sexes, since the two selection forces (female choice and male competition) conflict for selection on pala size, and partly from constraints, as females appeared unable to assess adult condition.

“…The presence and relative concentration of pheromone components in femoral secretions seem to vary consistently among individuals and might transmit chemical information about the characteristics and health state of a male Martín et al, 2007a). Behavioural experiments found evidence of female preferences for substrates scent marked by particular individual males, which suggest active pheromonal mate choice (e.g., López 2000, 2006a;López et al, 2002López et al, , 2003Olsson et al, 2003;López and Martín, 2005a). Substrate scent marks can also provide information to other males on individuality, fi ghting ability or dominance status (Aragón et al, 2001;Carazo et al, 2007;Martín et al, 2007b).…”

In spite of the importance of chemical signals (pheromones) in the reproductive behaviour of lizards, only a few studies have examined the role of specifi c chemical compounds as sexual signals. The secreted chemicals vary widely between species but whether this variation refl ects phylogenetic or environmental differences remains unclear. Based on mass spectra, obtained by GC-MS, we found 40 lipophilic compounds in femoral gland secretions of male green lizards (Lacerta viridis), including several steroids, α-tocopherol, and esters of n-C 16 to n-C 20 carboxylic acids, and minor components such as alcohols between C 12 and C 20 , squalene, three lactones and one ketone. We compared these chemicals with those previously found in other closely related green lizard species, and discussed how phylogenetical differences and/or environmental conditions could be responsible for the differential presence of chemicals in different lizard species.
