... a second population of cells that are most sensitive to light with vertical e-vector orientation, characterized by shallower polarization modulations, and smaller polarization sensitivity (PS) values than are typical for T1 cells. The level of PS values found in this study suggests that polarization...

... trained ants in a channel system that was covered with a polarization filter, providing only a single e-vector direction as a directional ‘celestial’ cue. Then we observed their homebound runs on a test field, allowing full view of the sky. In crucial experiments, the ants were exposed to a cue conflict...

... to demonstrate PS in the striped pyjama squid, Sepioloidea lineolata . This species displayed strong, consistent optokinetic nystagmic eye movements in response to a drum with stripes producing e-vectors set to 0 deg, 45 deg, 90 deg and 135 deg that would only be visible to an animal with PS. This is the first...

...Sonja Kleinlogel; N. Justin Marshall SUMMARY Gonodactyloid stomatopod crustaceans possess polarization vision, which enables them to discriminate light of different e-vector angle. Their unusual apposition compound eyes are divided by an equatorial band of six rows of enlarged, structurally...

...Martina Mussi; Theodore J. Haimberger; Craig W. Hawryshyn SUMMARY In this study, we demonstrate the capacity for damselfish (green chromis, Chromis viridis ) to discriminate between different e-vector orientations of ultraviolet polarized light. We examined the ability of green chromis to resolve...

...Verity J. Greenwood; Emma L. Smith; Stuart C. Church; Julian C. Partridge SUMMARY Many animals have sensitivity to the e-vector of linearly polarised light,which may assist in visually mediated behaviours such as navigation,signalling and foraging. However, it is still controversial as to whether...

... in particular exhibit a greater differential e-vector responsiveness to a changing e-vector than to e-vector variations among steady-state stimuli. While all four cell types respond modestly to light flashes at an e-vector of 90° to the preferred orientation, the dynamic response to a changing e-vector is small...

... of orientation with respect to the trained axis. Since the e-vector of polarised light provides an axial rather than a polar cue, the bimodal orientation exhibited by the lizards is consistent with the use of a celestial compass based on sky polarisation patterns. To confirm that the lizards could orient...
