“…Chemoreception is important in intraspecific communication of many animals, including invertebrates, reptiles and mammals (Wyatt 2003), where chemical traits alone may reveal dominance status (e.g. Apps et al 1988;Moore et al 1997;Zulandt-Schneider et al 2001). In lizards, femoral gland secretions might also signal dominance (Alberts et al 1992;Moreira et al 2006).…”

Intrasexual competition favours the evolution of conspicuous fighting ability badges. However, in spite of the fact that chemoreception is important in sexual selection of many animals, such as lizards, the role of chemical signals in males' contests is relatively unknown. Here, we show that proportions of cholesterol in femoral gland secretions of male Iberian rock lizards were related to their body size (which confers a competitive advantage in fights). Males discriminated chemically and responded aggressively to cholesterol stimuli presented on swabs. Moreover, we experimentally increased cholesterol in the scent of males, and staged encounters in neutral cages between two unfamiliar and size-matched males. Focal males lost more agonisitic interactions against males manipulated with cholesterol than in control tests. We suggest that differences in scent composition may reliably signal fighting ability in many lizard species, which would help to avoid the costs of fighting.

“…2002). Dominant male mice ( Mus musculus ) scent‐mark their territories extensively with urine streaks, and major urinary proteins in these marks bind two semiochemically active molecules (2‐s‐butyl‐4,5‐dihydrothiazole and 2,3‐dehydro‐exo‐brevicomin) that are associated with the males’ aggressive status (Apps et al . 1988; Harvey et al .…”

“…For instance, subordinate and dominant male cockroaches, Nauphoeta cinerea, differ in the ratio between 2-methylthiazolidine and 3-hydroxy-2-butanone (Moore 1997;Moore et al 1997), and in their cuticular hydrocarbon profile (Roux et al 2002). Dominant male mice (Mus musculus) scentmark their territories extensively with urine streaks, and major urinary proteins in these marks bind two semiochemically active molecules (2-s-butyl-4,5dihydrothiazole and 2,3-dehydro-exo-brevicomin) that are associated with the males' aggressive status (Apps et al 1988;Harvey et al 1989;Hurst 1993;Hurst et al 1998). In other lizard species, intrasexual aggression was mediated by pheromonal detection of rival males, but the specific chemicals involved were not identified (Cooper & Vitt 1987;López, Martín & Cuadrado 2002b, 2003.…”

Summary 1.Male competition for females often results in the evolution of conspicuous male traits that signal fighting ability or dominance status. Most studies examining mechanisms allowing these traits to function as reliable status signals (or badges) have focused on conspicuous visual or acoustic traits. However, many animals communicate chemically, and chemical traits alone may also signal male dominance status. 2. We examined whether chemicals in femoral gland secretions of male Iberian rock lizards ( Lacerta monticola monticola Boulenger 1905) may signal dominance status. 3. In staged encounters, larger males were dominant over smaller ones. While controlling for male body size, males of higher dominance status produced femoral secretions with higher proportions of hexadecanol and octadecanol. 4. Tongue-flick assays showed that males were able to (1) discriminate, by chemosensory cues alone, the different concentrations of hexadecanol from other chemicals presented in femoral secretions; (2) respond aggressively towards hexadecanol while responding neutrally towards other chemicals; and (3) show differential chemosensory and aggressive behaviours towards hexadecanol according to their own dominance status. 5. These results suggest that hexadecanol may be a reliable status badge. Moreover, because hexadecanol elicits male aggressive behaviour, subordinate males signalling high status ('cheaters') may end up paying high fighting costs. In addition, males that had higher dominance status, and that allocated higher proportions of hexadecanol to femoral secretions, had greater T-cell immune responses. This result suggests a possible link between quality of the immune system, dominance status, and chemical signals.

“…Naturally occuring pheromones in the urine of male mice have highly significant social functions (Hahn and Simmel, 1968;Brain et al, 1987;Jones and Nowell, 1989;Novotny et al, 1990). Some of these pheromones have been chemically identified (Apps et al, 1988) and related to the Y chromosome (Yamazaki et al, 1986;Maxson et al, 1989;Monahan et al, 1993). Both male and female mice have been found to use odor cues to discriminate between individuals with different genotypes (Yamaguchi et al, 1981).…”

Selective breeding for isolation-induced intermale aggression in mice: Associated responses and environmental influences

Aggressive (TA) and nonaggressive (TNA) lines of mice were established by selective breeding for isolation-induced intermale aggression. This paper summarizes and updates studies performed on the TA and TNA lines. The genetic analysis revealed that in these lines the genes for aggression are located on the autosomes and demonstrate a Mendelian segregation. The genes are expressed only in the presence of androgens which are normally present only in males. Behavioral and biological responses associated with high and low levels of aggression in TA and TNA mice are reviewed. Line differences have been found in olfactory communication and marking behavior, in maternal and predatory aggression in females, in locomotor activity, and in learning abilities. Also, correlated neurochemical and endocrinological responses to the selection have been detected. Maternal factors during the preweaning period do not significantly affect the development of aggression in TA and TNA males, while early postweaning exposure to aggression or sex enhanced later aggressive and sexual activity. Early experience and genetic disposition for aggression are correlated, with TA males showing the greatest increase in the behaviors studied.
