Methods used for testing scent detection dogs are heterogeneous and therefore susceptible for potential bias.
Unfortunately you can't really test for additivity very well in many of these figures because your individual manipulations of scent and nectar have such strong effects on seeds/eggs that the expected additive outcome would a negative number!
When tested for their attractiveness to the pollinator of each parent orchid species, we found that floral scent extracts of the hybrids triggered less inspecting flights and contacts by the male bees with the scented dummy than those of the parental orchid species.
Twenty-four hours after the contextual conditioning test, the mice were tested for cue memory by returning them to the same chamber, which was modified by the addition of various shapes and designs on the walls and a vanilla scent.
Finally, we were able to condense the information into a best practice standard for scent dog studies regarding the target odour, type of scent detection task and experimental set-up, samples used for training and testing, test design, dog trainer and training procedure and used dog breeds.
In addition, we recognized enriched transcripts by comparing the floral unigene databases for scent and scentless species, and by EST filtering to identify other genes for scent biosynthesis and scent modification candidates.
Altogether, the information provided on genes responsible for scent production and its evolutionary signatures will be relevant for understanding pollinator-driven selection on floral scent variation in plants.
This wax is for scent marking their territory.
In a pilot experiment, we found that naïve bats from our captive colony, like those tested by von Helversen and others [16], showed a strong preference for test tubes scented with dimethyl disulfide at the concentration that we used in the experiment.
Organoleptic testing identified, through scent, any residual petroleum taint in seafood that may render it unsafe for human consumption.
