Presentation Title: Effects of Serotonin on Aggressive Displays in Male Fiddler Crabs

Section: Poster Session Group 1 #5

Location: , Great Hall

Date & Time: Friday, April 19, 2013 - 10:30am - 11:15am


Previous studies have produced inconsistent results of serotonin’s effects on aggression in crustaceans.  While exogenous serotonin has attenuated aggressive displays in crayfish, it has also enhanced the associated behaviors in lobsters (Tierney and Mangiamele, 2001; Huber et al., 1997).  I sought to address these conflicting results by investigating the effects of serotonin on aggressive behavior in another crustacean, the fiddler crab (Uca pugilator), whose nervous system is relatively simple and easy to study.  Adult male fiddler crabs were injected with either a control saline solution or serotonin at a behaviorally relevant dose.  The animals were placed in pairs in an open circular arena, and their aggressive behaviors were categorized and quantified.  Serotonin levels before and after drug administration were also assayed using ELISA.  Given that serotonin is a key neurotransmitter also found in vertebrates, the results of this work have implications for treatment of mood-related disorders.
