Behavioral And Hormonal Flexibility Across Light Environments In Guppies (Poecilia Reticulata), Julia C. Walz
Behavioral And Hormonal Flexibility Across Light Environments In Guppies (Poecilia Reticulata), Julia C. Walz
Master's Theses
Behavior may be dramatically influenced by changing environments, and differences in light intensity environments may have important behavioral consequences. One approach to understanding changes in behavior is by studying behavioral syndromes, suites of correlated behaviors reflecting between individual consistencies in behavior expressed within a behavioral situation (e.g., correlations between antipredator behaviors in different habitats), or across behavioral contexts (e.g., correlations among feeding, antipredator, or mating behavior) (Sih et al. 2004a). Guppies (Poecilia reticulata) provide a great model system to study behavior. Guppies are small, freshwater tropical fish that inhabit still pools in swift-flowing streams, and the backwaters of small rivers …

The Significance Of The Male Display During Male-Male Interactions In Guppies (Poecilia Reticulata), Rebecca Nuffer, Samantha M. Alburn
Biological Sciences
Guppies, Poecilia reticulata, are a model species for studies of female preference based on male courtship displays; however, males also display to each other in an aggressive context, and little attention has been paid to the role of male-male displays. The display involves a male positioning his body in front or to the side of another male, arching his body, and quivering with his dorsal fin splayed. To understand what behaviors elicit a male display, we assigned individual males a dominance status. We then examined the relationship between dominance status and the number of displays delivered and received. By …
