Predator-induced nest site preference: safe nests allow courtship in sticklebacks
Article Abstract:
The reduction in courtship activity among male three-spined sticklebacks, Gasterosteus aculeatus, in open and vegetated state in the presence of a predator was recorded to determine the influence of predation on nest site choice. Results reveal that the presence of predators reduces the courtship activities of males in open sites more than that of males in vegetated sites. This reduction is pronounced among males in competition. Females chose males in vegetated sites. The implications of these findings are discussed.

The relationship between signal quality and physical condition: is sexual signalling honest in the three-spined stickleback?
Article Abstract:
The relationship between red coloration in male three-spined sticklebacks, Gasterosteus aculeatus, and condition is curvilinear, with males in poor condition increasing their signal quality. It has been established that feeding history and the condition of the male can affect signalling effort. Males in very poor condition may not survive the parental phase, and a female that bases her mate choice solely on the red coloration may therefore mate with a poor-quality male and have no reproductive success.

Increased signalling effort when survival prospects decrease: male-male competition ensures honesty
Article Abstract:
Research on signalling behavior by male sticklebacks has found that their signalling is more honest, measured by red coloration, where there is competition between males.
