...) that comprise their olfactory organs. We also calculated the olfactory thresholds and relative effectiveness of amino acid odorants for each species. The olfactory organs varied in both the number of lamellae and lamellar surface area, which may be related to their general habitat, but neither correlated...

...Olle Lind; Almut Kelber SUMMARY We have used behavioural tests to determine the intensity thresholds of colour vision in Bourke's parrots ( Neopsephotus bourkii ) and budgerigars ( Melopsittacus undulatus ). We have also examined the relationship between these thresholds and the optical...

...Anne-Catherine Mailleux; Claire Detrain; Jean-Louis Deneubourg SUMMARY The decision for an ant forager to launch recruitment is governed by an internal response threshold. Here, we demonstrate that this threshold (the desired volume) triggering trail-laying increases under starvation...

... on the platform for up to 12 min, the whales whistled in response to 500 ms tones projected at random intervals to assess their hearing threshold at each depth. Analysis of response whistle spectra, whistle latency in response to tones and hearing thresholds showed that the increased hydrostatic pressure at depth...

... in the sacculus) or has background noise been a significant consideration for the design of the transducer? Response thresholds vary considerably among the three amphibian auditory organs and may differ between neighboring afferent fibers in the same auditory organ by as much as 60 dB. The frog sacculus...

... acceleration or deceleration step lasted for 5 min. Conditions within the spacecraft are such that only near-weightlessness (microgravity) is achieved (indicated by ‘0 g ’ in Fig. 6 ). The residual acceleration during the ‘threshold experiments’ did not exceed 10 −3 g as measured by accelerometers...

...Bernd Kramer; Ivo Kaunzinger ABSTRACT Eigenmannia’s frequency and intensity discrimination thresholds were determined for a range of seven frequencies (50–1700Hz), centered on a fish’s individual discharge frequency, using a conditioned go/no-go paradigm. The threshold criterion was ‘50% correct...

...F. E. Doujak ABSTRACT The absolute-intensity threshold of the optokinetic response in the crab Leptograpsus variegatus was measured using a moving continuous monochromatic point source. The results are compared to the photoreceptor responses of the same animal ( Doujak, 1984 ), to determine...
