Artificial Light at Night Alters Physiology, Behavior, and Reproduction in the Western Mosquitofish (Gambusia affinis)
Human population growth and its associated effects have contributed to the rapid decrease of biodiversity worldwide. Artificial light at night (ALAN) is an anthropogenic pollutant that is increasing with the spread of urbanization and may contribute to biodiversity declines. ALAN alters the …

Overcoming evolutionary history: conditioning the endangered Barrens topminnow to avoid predation by the invasive Western mosquitofish
… by the introduction of an invasive predator: the Western Mosquitofish (WMF), Gambusia affinis. This study used conditioning to help the BTM escape its evolutionary trap, and data showed that conditioned fish responded significantly different to the presentation of WMF compared to control fish, and …

An experimental test of intra- and inter-specific competition between invasive western mosquitofish (Gambusia affinis) and native plains topminnow (Fundulus Sciadicus)
… topminnow (Fundulus Sciadicus) and invasive western mosquitofish (Gambusia affinis) at 16, 22, and 28 °C. Data were analyzed using the isodar theory, which assumes that animals are ideally distributed to maximize their fitness and thus their distributions measure the quality and quantity of …

Social learning and its effect on conservation efforts in the Barrens Topminnow: an evaluation of conditioning and social learning as a viable longterm solution to evolutionary traps
The invasive Western Mosquitofish (WMF), Gambusia affinis, has facilitated the extinction and endangerment of multiple freshwater fish species, including the Barrens Topminnow (BTM), Fundulus julisia. In my study, I investigated if BTMs are capable of socially learning conditioned predator …

Friends in Low Places: Responses of a Benthic Stream Fish to Intra-Guild Alarm Cues
… Minnows (Notropis nubilus), recently-introduced Western Mosquitofish (Gambusia affinis), and native Oklahoma Salamanders (Eurycea tyrnerensis), all of whom are vulnerable to the same predators. We tested the responses of darters to the damage-released alarm cues of conspecifics (positive …

Oviposition Site Selection By Mosquitoes: Predator-Released Kairomones And Responses To Different Taxa
… from the cue) released by Gambusia affinis (Western mosquitofish), Lepomis cyanellus (green sunfish), and Procambarus hayi (straightedge crayfish) when locating oviposition sites. Three paired experiments (Control vs. Predator-conditioned water) were conducted, one for each predator species. …
