...Paul A. Moore; David Edwards; Ana Jurcak-Detter; Sara Lahman ABSTRACT Orientation within turbulent odor plumes occurs across a vast range of spatial and temporal scales. From salmon homing across featureless oceans to microbes forming reproductive spores, the extraction of spatial and temporal...

...Sean Copley; Kalyanasundaram Parthasarathy; Mark A. Willis ABSTRACT While tracking odor plumes, male hawkmoths use optic flow cues to stabilize their flight movements with respect to their environment. We studied the responses of freely flying moths tracking odor plumes in a laboratory wind tunnel...

... source. However, pinpointing the precise location of an odor source requires use of both visual and olfactory modalities, aided by odor plumes. Here, we investigated odor-tracking behavior in fruit flies ( Drosophila melanogaster ) presented with low- or high-contrast visual landmarks, either paired...

... the position of their nostrils relative to the bottom. While navigating in and around an odor plume, adults raised their snouts, vertically into the water column, or buried them down into the stream bed. Combined attractant/dye releases showed that these adults were adjusting the position of their snouts...

... with chemically mediated navigation. We exposed individual whelks to turbulent odor plumes in free-stream velocities of 1.5,5, 10 or 15 cm s –1 , or with one of two obstructions placed upstream of the odor source in an intermediate flow of 5 cm s –1 . Measurements of velocity and stimulus properties confirmed...
