“…However, even for power variations of ±15% the simulations predict values of η between 70% for Anti(out) and 95% for Gauche(out) (see Supplementary Material). The flux for a specific conformer behind the selection slits can be estimated using the vapor pressure of PEA at 410 K [68], the characteristics of a pulsed Even-Lavievalve [69,70], a 100 Hz laser illuminating an area of 1 mm 2 , and the diffraction pattern of the Gauche(out) conformer shown in Fig. 3a.…”

“…The particle flux j = nv = pv/k B T is determined by the partial pressure p of 2-phenylethylamine, the temperature T , and the velocity v of the molecules. Taking the velocity of an adiabatic expansion of Argon (v = 650 m/s) and the partial pressure of 2-phenylethylamine at T = 410 K [68], this yields a flux of j = 2.4 × 10 27 m −2 s −1 .…”

We establish that matter-wave diffraction at near-resonant ultraviolet optical gratings can be used to spatially separate individual conformers of complex molecules. Our calculations show that the conformational purity of the prepared partial beams can be close to 100% and that all molecules remain in their electronic ground state. The proposed technique is independent of the dipole moment and the spin of the molecule and thus paves the way for structure-sensitive experiments with hydrocarbons and biomolecules, such as neurotransmitters and hormones, which have evaded conformer-pure isolation so far.

“…It also has been found in non-carnivorous species at much lower concentrations (Ferrero et al, 2011 ). Like pyrazines it is a moderately volatile compound (vapor pressure 35 Pa, Mokbel et al, 2009 ), therefore, probably not very effective over longer periods of time. In behavioral studies, rodents avoided a PEA odor source similarly as they avoided predator urines.…”

Are single odorous components of a predator sufficient to elicit defensive behaviors in prey species?

When exposed to the odor of a sympatric predator, prey animals typically display escape or defensive responses. These phenomena have been well-documented, especially in rodents, when exposed to the odor of a cat, ferret, or fox. As a result of these experiments new discussions center on the following questions: (1) is a single volatile compound such as a major or a minor mixture constituent in urine or feces, emitted by the predator sufficient to cause defensive reactions in a potential prey species or (2) is a whole array of odors required to elicit a response and (3) will the relative size or escapability of the prey as compared to the predator influence responsiveness. Most predator-prey studies on this topic have been performed in the laboratory or under semi-natural conditions. Field studies could help to find answers to these questions. Australian mammals are completely naïve toward the introduced placental carnivores. That offers ideal opportunities to analyze in the field the responses of potential prey species to unknown predator odors. During the last decades researchers have accumulated an enormous amount of data exploring the effects of eutherian predator odors on native marsupial mammals. In this review, we will give a survey about the development of olfactory research, chemical signals and their influence on the behavior and—in some cases—physiology of prey species. In addition, we report on the effects of predator odor experiments performed under natural conditions in Australia. When studying all these literature we learned that data gained under controlled laboratory conditions elucidate the role of individual odors on brain structures and ultimately on a comparatively narrow range behaviors. In contrast to single odors odor arrays mimic much more the situation prey animals are confronted to in nature. Therefore, a broad range of methodology—from chemistry to ecology including anatomy, physiology, and behavior—is needed to understand all the different (relevant) stimuli that govern and guide the interactions between a predator and its potential prey.
