Dispersal Behavior Of Mosquitofish (gambusia Holbrooki)
Mosquitofish (Gambusia holbrooki) are native to the southeastern United States but invasive elsewhere, and are dominant predators in many ecosystems that they inhabit. Information on dispersal behavior will help better understand and predict mosquitofish metapopulation dynamics and invasions. I …

Behavioral and Reproductive Plasticity in Eastern Mosquitofish (Gambusia Holbrooki) in Response to Predatory Cues
… I tested if a live-bearing non-ostariophysan, Gambusia holbrooki, exhibited a similar behavioral response to its injured conspecifics. I also examined the effects of exposure to this and other predatory cues during a single pregnancy cycle. I hypothesized that immediate exposure to the cues …

Cognitive Abilities in Fish: Biological Predictors and Impact on Reproductive Success
… 1, I explore the ability of mosquitofish (Gambusia holbrooki) to express inhibitory control, an essential cognitive trait that inhibits impulsive actions in favour of delayed rewards. I show how sex, age, and personality can impact their inhibitory control. Chapter 2 investigates the effect …
