Among vertebrates, teleost eye diversity exceeds that found in all other groups. Their
spectral sensitivities range from ultraviolet to red, and the number of visual pigments varies …

Animal signal colors evolve to efficiently stimulate conspecific visual systems. The sensory
drive hypothesis proposes that species differences in habitat light conditions favor the …

Sensory systems allow for the transfer of environmental stimuli into internal cues that can
alter physiology and behavior. Many studies of visual systems focus on opsins to compare …

Light availability is highly variable, yet predictable, over various timescales and is expected
to play an important role in the evolution of visual signals. Courtship displays of the wolf …

Animals evolve in complex selective regimes, where a suite of different factors can shape
signal use. We might predict that more closely related species will exhibit more similar …

In 1992, The American Naturalist published a special supplement entitled:“Sensory Drive.
Does Sensory Drive Biology Bias or Constrain the Direction of Evolution?” organized by …

The presence of stable color polymorphisms within populations begs the question of how
genetic variation is maintained. Consistent variation among populations in coloration …

Sensory drive can lead to the evolution of signals that are optimized to the environment in
which they are perceived. However, when environmental conditions change, the interactions …

Reinforcement can occur when maladaptive hybridization in sympatry favors the evolution of
conspecific preferences and target traits that promote behavioral isolation (BI). In many …
