Sexual communication, including species recognition, sex recognition, synchronization of sexual activity, and assessment during sexual competition... 

It is unknown which compounds are involved in Liolaemus communication. However, information available from the chemical composition of the lipidic fraction of the precloacal secretions suggests that individuals, populations and species can be discriminated by the chemical profile of these secretions (Escobar, Escobar, Labra and Niemeyer 2003 Escobar, Labra and Niemeyer 2001). This, in addition to probable chemical differences in the other sources of chemosignals, may allow individual, population and species recognition (Labra et al. 2001). Based on the individual variation observed in the composition of the secretions of L. bellii (Escobar et al. 2001), it is likely that lizards can achieve self-recognition, and also that they can extract detailed information about sender characteristics, as we have seen for L. monticola (Labra 2006). 

Because D-AspRS and AsnRS select tRNA and tRNA , respectively, they recognize distinct elements in each tRNA whereas ND-AspRS that aspartylates both tRNAs recognizes elements common to the two tRNAs. Most tRNA P identity elements are conserved in the various species " recognition of tRNA by AspRS occurs by a similar pattern. "" Study of the tRNA elements determining aspartylation by the D- and ND-AspRSs from T. thermophilus, AspRS 1 and AspRS2 respectively, has shown that with only one exception the same nucleotides determine aspartylation by the two AspRSs. " Specificity of each AspRS is related to distinct... 

Species recognition Responses to vaginal secretion marks Main olfactory system... 

In the golden hamster, the VNO is essential for certain reproductive behaviors, while the main olfactory system mediates responses that involve species recognition (Johnston, 1992 Table 5.2). As in mice, removal of the VNO impairs sexual behavior in male golden hamsters, but only if carried out before the animal had had sexual experience (Meredith, 1986). The same is true for ultrasonic vocalizations. 

A particularly thorny problem that remains to be resolved is the species-recognition process that is mediated by physical or tactile cues associated with silk or the cuticle, as well as pheromones on these two substrates. To date, the lipid mixtures associated with silk or cuticle seem to display the most variable structures and blends, making them good candidates for species recognition. In contrast, the more polar components appear to be less species specific and so are less likely to be the key factors in intraspecific recognition.

It is tempting to speculate that differences in hydrocarbon phenotypes are correlated with speciation. These variations have been shown to be important for mating or species recognition in a number of species (Drosophilidae and Culicidae in Diptera, Isoptera, etc.). However, it cannot be ruled out that these differences act on the quantity of a specific hydrocarbon and are due to environmental factors affecting hydrocarbon production. In some cases, hydrocarbon production seems to be inherited, suggesting that external factors may not be the only parameters involved. Hybridism and, on the contrary, sexual isolation, can be used to illustrate that chemotaxonomy has an evolutionary basis. This section presents different examples in various orders to illustrate this issue, i.e., Diptera, Isoptera, Orthoptera, and Coleoptera.
