Learning facilitates behavioral plasticity, leading to higher success rates when
foraging. However, memory is of decreasing value with changes brought about by
moving to novel resource locations or activity at different times of the day.
These premises suggest a foraging model with location- and time-linked memory.
Thus, each problem is novel, and selection should favor a maximum likelihood
approach to achieve energy maximization results. Alternatively, information is
potentially always applicable. This premise suggests a different foraging model,
one where initial decisions should be based on previous learning regardless of
the foraging site or time. Under this second model, no problem is considered
novel, and selection should favor a Bayesian or pseudo-Bayesian approach to
achieve energy maximization results. We tested these two models by offering honey
bees a learning situation at one location in the morning, where nectar rewards
differed between flower colors, and examined their behavior at a second location
in the afternoon where rewards did not differ between flower colors. Both
blue-yellow and blue-white dimorphic flower patches were used. Information
learned in the morning was clearly used in the afternoon at a new foraging site.
Memory was not location-time restricted in terms of use when visiting either
flower color dimorphism.
