Familiarity And Its Impacts On Male Mate Preference The Sailfin Molly, Poecilia Latipinna, Abigail Doza, Alyssa Back
Student Symposium
Mating behaviors are an integral part of the life history and ecology of many species. Male mate preferences are an especially understudied area of research. We examined male mate preference for familiar and unfamiliar female fish in the sailfin molly Poecilia latipinna. We hypothesized that males would prefer familiar females as they may have been able to gather additional information concerning the female’s reproductive status. Males were isolated for a minimum of four days and then tested in a choice tank with two females of similar size. After the experiment, each male was randomly assigned to be with one of …

Investigating Crayfish (Orconectes Rusticus) Aggression And How It Varies With Resource Availability, Allie Smith, Rebecca Lipster
Student Symposium
Animals that express agonistic behavior toward one another are prone to recognizing hierarchical status among individuals. Recognizing status has proven to be evolutionarily advantageous for crayfish (Orconectes rusticus) because it allows dominant individuals to maximize resources and permits subordinate individuals to steer clear of potentially costly battles. More specifically, two crayfish experiencing aggression can generally determine who the dominant and subordinate individuals are in a fight. A higher social status within a social hierarchy can allow for increased access to differing resources, such as food, mates, and shelter. In this experiment, we want to see if limiting resources will affect …
Influence Of Sex And Ambient Temperature On Asian Elephant (Elephas Maximus) Dusting Behavior, Kelly Summers
Influence Of Sex And Ambient Temperature On Asian Elephant (Elephas Maximus) Dusting Behavior, Kelly Summers
Student Symposium
Previous studies indicate that elephant dusting behavior can be promoted by several factors including environmental temperature and social interaction. We hypothesized that (1) if dusting serves as a voluntary thermoregulatory function, then increased ambient temperature would result in increased dusting performance, and (2) if dusting is influenced by social interactions, then male and female elephants will exhibit dusting at similar rates in a group setting. Preliminary data indicated no significant relationship between temperature and the rate of dustings performed. Contrary to our predictions, females exhibited a greater rate of dusting than males in a social environment. The current study reexamines …
