The dual effect of stickleback nuptial coloration on rivals: manipulation of a graded signal using video playback

Article Abstract:

Reproductive male three-spined stickleback, exhibit a dual response when presented with images of other males with various color intensities. Research found that the dully colored males were met with low aggression and fear, while brighter colored males caused fear and aggression, often not acted upon, in the subjects. A combination of bright and dull fish brought out the aggression in the subject, targetted at he dull fish. This is likely the result of the intensity of the reaction of the fish against his bright colored challenger combined with the relatively small threat perceived in attacking the dull fish.

Context-dependent response to red coloration in stickleback

Article Abstract:

The response to relative color intensity is context dependent in male three spined stickleback, Gasterosteus aculeatus. The change in the internal state of males is a reason for this response. The intensity of its aggressive response is dependent on the proximity to the nest. Aggression and fear determine the attack response which is a dual effect process. Spatial location plays an important role in influencing the response of the male stickleback to its rivals.

Inter-nest distance and sneaking in the three-spined stickleback

Article Abstract:

Sneaking is an alternative mating behavior shown by male three-spined sticklebacks and it is influenced by the distance between nests. Sticklebacks' sneaking behavior in eight natural habitats was studied. Results indicated that sneaking behavior is shown when sexually active males are close to each other and when the distance between nests is small.
