Abstract
The objective of this study was to determine how seasonal changes affect the foraging activity and wood consumption of the Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), in New Orleans, LA. There was a significant correlation between wood consumption and ai...

Abstract
Studies of olfactory learning in Drosophila have provided key insights into the brain mechanisms underlying learning and memory. One type of olfactory learning, olfactory classical conditioning, consists of learning the contingency between an odor with an aversive or appetitive stimu...

Abstract
We randomized the order of type of trial (5, 10 and 15 items presented in the display) while it remained constant (10 items) in Experiments 2A and 2B. In the later experiments, we also changed time presentation of visual display (3000 vs. 1300 ms, respectively). Results showed no differential effect...

Abstract
There are few demonstrations of basic associative learning phenomena using appetitive procedures in mice. This article describes procedures for obtaining four associative learning phenomena in mice, using an appetitive conditioning procedure in which the reinforcer was delivery of a sucrose pellet,...

Abstract
We assessed emotional behavioral responses of rhesus macaques that received bilateral ibotenic acid lesions of the amygdala or hippocampus at 2 weeks of age and sham-operated controls. At 9 and 18 months of age, animals interacted with novel objects that varied in visual complexity as a means of var...

Abstract
We investigated the genetic structure of populations of the Great Yellow Bumblebee (Bombus distinguendus Morawitz) in the UK, where this species has undergone a precipitous decline. By means of a mixture of analytical methods and simulation, we also extended--and then applied--genetic methods for es...

Abstract
This study examined the influence of soil type and moisture availability on termite foraging behavior. Physical properties of the soil affected both tunneling behavior and shelter tube construction. Termites tunneled through sand faster than top soil and clay. In containers with top soil and clay, t...

Spontaneously hypertensive rats (SHR) and Wistar rats were evaluated in the successive-encounters procedure (an operant simulation of natural foraging) with the idea of assessing differences between them in their preference for variable schedules of reinforcement. In this procedure, after satisfying...
