Exploring the threat-sensitive predator avoidance hypothesis on mate competition in two wild populations of Trinidadian guppies.

Author(s): Chuard PJC, Grant JWA, Ramnarine IW, Brown GE

The intensity of mate competition is often influenced by predation pressure. The threat-sensitive predator avoidance hypothesis predicts that prey should precisely adjust their fitness-related activities to the level of perceived acute predation risk and th...

Abstract

Context can influence the number of responses elicited by a discrete, appetitive conditioned stimulus (CS) but can context control when a CS elicits a response? To test this fundamental question, we gave male, Long-Evans rats Pavlovian conditioning sessions in which the same auditory conditioned stimulus (CS, 30?s, 15 trials/session) was presented in 2 different physical contexts on alternating days, according to a within-subjects design. In one context, called the early context, alcohol (15% ethanol, 0.2?ml/trial) was delivered from the onset of the 5th second until the termination of the 10th second of the 30?s CS. In the second late context, alcohol was delivered from the onset of the 25th second until the termination of the 30th second of the same CS. In a comparison of the last session of training, the probability of making a conditioned response during the first four seconds of the CS was significantly higher in the early context than in the late context. This result shows that context can signal when an unconditioned stimulus occurs in relation to a CS and highlights a role for context in controlling precisely timed alcohol-seeking responses.
