(6R, 10R)-6,10,14-trimethylpentadecan-2-one, a dominant and behaviorally active component in male orchid bee fragrancesThomas Eltz
Sensory Ecology Group, University of Dusseldorf, Universitatstrasse 1, Dusseldorf, Germany
J Chem Ecol 36:1322-6. 2010..Its attractiveness to males suggests that low-volatility compounds have a function in male signals, e.g., serve as a "base note" in complex odor bouquets...
An olfactory shift is associated with male perfume differentiation and species divergence in orchid beesThomas Eltz
Department of Neurobiology, University of Dusseldorf, 40225 Dusseldorf, Germany
Curr Biol 18:1844-8. 2008..However, the response of females to the diverged signals remains unknown...
Reconstructing the pollinator community and predicting seed set from hydrocarbon footprints on flowersSebastian Witjes
Sensory Ecology Group, University of Dusseldorf, Dusseldorf, Germany
Oecologia 166:161-74. 2011..We suggest that quantifying cumulative footprint hydrocarbons provides a novel way to assess floral visitation by insects and can be used to predict seed set in pollen-limited plants...
Chemical niche differentiation among sympatric species of orchid beesYvonne Zimmermann
Department of Neurobiology, Sensory Ecology Group, University of Düsseldorf Universitätstr I, 40225 Dusseldorf, Germany
Ecology 90:2994-3008. 2009..Our findings are consistent with the hypothesis that male fragrance signals evolve to convey premating isolation...
Reconstructing the pollinator community and predicting seed set from hydrocarbon footprints on flowersSebastian Witjes
Sensory Ecology Group, University of Dusseldorf, Universitatsstr 1, 40225 Dusseldorf, Germany
Oecologia 165:1017-29. 2011..We suggest that quantifying cumulative footprint hydrocarbons provides a novel way to assess floral visitation by insects, and that this method can be used to predict seed set in pollen-limited plants...
Enfleurage, lipid recycling and the origin of perfume collection in orchid beesThomas Eltz
Department of Neurobiology, University of Dusseldorf, Dusseldorf 40225, Germany
Proc Biol Sci 274:2843-8. 2007..This, and a prominent overlap in secretory products, led us to propose that perfume collection evolved from scent-marking in ancestral corbiculate bees...
Hydrocarbon footprints as a record of bumblebee flower visitationSebastian Witjes
Department of Neurobiology, Sensory Ecology Group, University of Dusseldorf, Universitatsstr 1, 40225 Dusseldorf, Germany
J Chem Ecol 35:1320-5. 2009..The analysis of petal extracts by gas chromatography could provide a cheap and reliable way of quantifying bumblebee visits in landscape scale studies of pollination...
Foraging scent marks of bumblebees: footprint cues rather than pheromone signalsJessica Wilms
Department of Neurobiology, Sensory Ecology Group, University of Dusseldorf, Universitatsstr 1, 40225 Dusseldorf, Germany
Naturwissenschaften 95:149-53. 2008..We conclude that repellent scent marks are mere footprints, which foraging bees avoid when they encounter them in a foraging context...
Tracing pollinator footprints on natural flowersThomas Eltz
Department of Neurobiology, Sensory Ecology Group, University of Dusseldorf, Universitatsstr 1, 40225 Dusseldorf, Germany
J Chem Ecol 32:907-15. 2006..Continuous footprint accumulation necessitates new explanations concerning the reversibility of "repellent scent marks" of bumblebees...
Species-specific antennal responses to tibial fragrances by male orchid beesThomas Eltz
Department of Neurobiology, Sensory Ecology Group, University of Dusseldorf, Universitatsstr 1, 40225 Dusseldorf, Germany
J Chem Ecol 32:71-9. 2006..Antennal specialization to conspecific bouquets adds additional strength to the argument that specificity is an important evolutionary aspect of euglossine tibial fragrances...
Juggling with volatiles: exposure of perfumes by displaying male orchid beesThomas Eltz
Department of Neurobiology, Sensory Ecology Group, University of Dusseldorf, Universitatsstr 1, 40225 Dusseldorf, Germany
J Comp Physiol A Neuroethol Sens Neural Behav Physiol 191:575-81. 2005..Although the findings strengthen, the view that the volatiles serve as attractants in the context of mating behavior, the signal addressee, conspecific males or females, has yet to be found...
