The reproductive state of the female influences the response to olfactory sex signals, where preovulatory females show a strong behavioral response to male-derived sex cues, whereas postovulatory females do not (Clement et al. This difference in response, determined by the reproductive state of the female, was used to confirm that the male-derived chemical cues acted as sex signals.
Female preference for male odor in has already been demonstrated (Cole and Smith 1992), so was not attempted here.
All preference tests were performed using females of each species in 2 reproductive conditions: preovulatory (females that spawn in the next 24h following testing) and postovulatory (females that have spawned in the last 24h).2005; ten Cate and Rowe 2007), by extrapolation, allopatric species are less likely to develop discriminatory processes and respond to each others signals (Ord et al. Currently, there is a lack of experimental evidence supporting an absence of inherent discriminatory processes in geographically separated organisms, especially among vertebrates.Understanding whether allopatric species inherently respond to each others signals has important evolutionary implications (Burnard et al.This is your chance to dive head first into an endless stream of the most perverted voyeur videos in the world.Watch hundreds of hidden camera videos of hot amateurs caught in the act of being real naughty; if its voyeuristic and perverted, you can be sure to find it in our tube site.
