Does sensory modality influence behavioral change? Investigations in the Trinidadian guppy.

To gain reliable information about the environment, organisms often attend to multiple cues. Environmental cues vary temporally in their presence, intensity, and accuracy, and thus are integrated using different sensory modalities. However, it is unclear whether short-term cue exposure received by different sensory modalities initiates long-term changes in behavioral phenotypes, or whether specific traits are impacted based on the modality by which a cue is received. The aim of this study was to examine how short-term exposure to different sensory cues, both individually and in combination, influenced plastic behavioral responses in the Trinidadian guppy (Poecilia reticulata). Adult guppies were exposed to visual, olfactory, or a combination of both cues from a natural predator, the pike cichlid (Crenicichla spp.), over a two-week period. We then measured latency to emerge, activity, and exploration in a standard open field assay. Investigating how phenotypes differ based on the type of cue an individual receives can provide insight into whether cues received by different sensory modalities work independently or synergistically to produce a phenotype.
