... hosts, which are also used to discriminate between hosts and non-hosts, and A. vaga demonstrated a behavioural activity for 4-oxoisophorone. A high sensitivity to floral scents enables the specialized bees to effectively find flowers and it appears that A. vaga bees are highly tuned to 4-oxoisophorone...

... complex non-spherical shapes reminiscent of those described in other ocelli. Intracellular electrophysiology revealed that the photoreceptors have high absolute sensitivity, but that the threshold location varied widely between 10 9 and 10 11 photons cm –2 s –1 . Higher sensitivity and greater visual...

..., have only around 30 times greater optical sensitivity than the eyes of their closest diurnal relatives, a fact that is apparently inconsistent with their remarkable nocturnal visual abilities. Moreover, signals generated in the photoreceptors, even though amplified by a high transduction gain, are too...

... of photoreceptors, they use one highly sensitive receptor, thus improving the signal-to-noise ratio. However, nocturnal moths and geckos can discriminate colours at extremely dim light intensities when humans are colour-blind, by sacrificing spatial and temporal rather than spectral resolution. The advantages...

... Gastropoda vision optics Ampularia sp sensitivity retina Gastropods display a very wide range of eye construction, from small open eyes filled with a jelly-like material to large and extremely well-developed camera-type eyes ( Zunke, 1978 ). Some of these have spherical graded-index lenses...

... 1992 eye gastropod sensitivity resolution optics Littorina littorea A well-developed camera-type (simple) eye is potentially a superb visual organ which, for the space it occupies, has the best information capacity of all optical designs. The presence of this kind of eye...
