..., we ask whether honey bees discriminate between floral-fragrance isomers in an appetitive context. We used the olfactory conditioning of the proboscis extension response, which allows training a restrained bee to an odor paired with sucrose solution. Bees were trained under an absolute (a single...

.... Sensory systems must balance rapid detection of a stimulus with perception of fine details that enable discrimination between similar stimuli. Here, we show that in a species of weakly electric fish, Apteronotus leptorhynchus , two coding strategies are employed for these separate behavioral tasks. Using...

.... To this purpose, the ability to discriminate among different stimuli with different valence is essential, but it is also important to be able to generalise, i.e. to treat different but similar stimuli as equivalent, as natural variation does not necessarily affect stimulus valence. Animals can thus extract...

... arising from diet, rather than mobilization from adipose tissue. Discrimination factors were used in combination with a mixing model incorporating FA and lipid concentrations to estimate the diet of eiders fed a binary mixture with contrasting isotopic signatures. Diet estimates varied with FA but mean...

... O values of different tissues must account for inter-tissue discrimination factors; and (3) δD/δ 18 O linear relationships are probably as prevalent in animal systems as they are in geohydrological systems. These relationships may prove to be useful tools in animal isotopic ecology. * Author...

We compared acquisition, retention and discrimination between foragers with short and long foraging durations and age-matched nurse bees. Our data...

We analyzed their frequency distributions to assess if and how frequency properties could be used to discriminate between vibration sources and used vibration playbacks to examine the effects of frequency properties on the escape hatching response.

Crickets ( Teleogryllus oceanicus ) were able to discriminate between sources separated by 11.25 ° (1/32 of a circle) in azimuth directly ahead of them; acuity declined to 45 ° in azimuth for sound sources 90 ° to the side and then improved to 33.75 ° at the rear.
