Olfactory learning and memory in the bumblebee Bombus occidentalis
In many respects, the behavior of bumblebees is similar to that of the closely related honeybees, a long-standing model system for learning and memory research. Living in smaller and less regulatedExpand

Brain Allometry and Neural Plasticity in the Bumblebee Bombus occidentalis
Brain plasticity is a common phenomenon across animals and in many cases it is associated with behavioral transitions. In social insects, such as bees, wasps and ants, plasticity in a particularExpand

Decision-making and associative color learning in harnessed bumblebees (Bombus impatiens)
In honeybees, the conditioning of the proboscis extension response (PER) has provided a powerful tool to explore the mechanisms underlying olfactory learning and memory. Unfortunately, PERExpand

Evolution of brain size in class-based societies of fungus-growing ants (Attini)
A social lifestyle is often assumed to be more complex than a solitary one, due to social demands that may require increased cognitive capabilities. These nested assumptions underlie hypotheses toExpand

Color-dependent learning in restrained Africanized honey bees
Associative color learning has been demonstrated to be very poor using restrained European honey bees unless the antennae are amputated. Consequently, our understanding of proximate mechanisms inExpand

Metabolic scaling in insects supports the predictions of the WBE model.
The functional association between body size and metabolic rate (BS-MR) is one of the most intriguing issues in ecological physiology. An average scaling exponent of 3/4 is broadly observed acrossExpand

Learning from learning and memory in bumblebees
The difficulty to simultaneously record neural activity and behavior presents a considerable limitation for studying mechanisms of insect learning and memory. Expand

Experimental evidence for a magnetic sense in Neotropical migrating butterflies (Lepidoptera: Pieridae)
We tested whether migrating Aphrissa statira butterflies orient with a magnetic compass. We captured migrants flying over Lake Gatun, Panama, and exposed experimental butterflies to a strong magneticExpand

Do leafcutter ants, Atta colombica, orient their path-integrated home vector with a magnetic compass?
Leafcutter ants, Atta colombica, forage over 250 m in structurally complex, Neotropical rainforests that occlude sun or polarized light cues. Night foraging makes the use of celestial cues andExpand

Sensory allometry, foraging task specialization and resource exploitation in honeybees
Insect societies are important models for evolutionary biology and sociobiology. The complexity of some eusocial insect societies appears to arise from self-organized task allocation and groupExpand
