Meeting Abstract 115.6 Tuesday, Jan. 7 11:30 Differential growth rates of body segments explain ontogenetic shifts in heart position ANDERSON, GE*; SECOR, SM; University of Alabama; University of Alabama ganderson@crimson.ua.edu Relative heart position in snakes has been hypothesized to be adaptively correlated with habitat and shown to be conserved phylogenetically. For snakes, relative heart position also shifts […]

Beetle horn diversity does shape affect performance during fights
Meeting Abstract 115.2 Tuesday, Jan. 7 10:30 Beetle horn diversity: does shape affect performance during fights? MCCULLOUGH, E.L.; University of Montana, Missoula mccullough.e@gmail.com Rhinoceros beetles exemplify the elaborate morphologies that can result from sexual selection. Males have long horns on their head and prothorax that they use in fights over reproductive access to females. Species vary dramatically […]

Self healing of fire ant aggregations
Meeting Abstract 115.2 Wednesday, Jan. 7 13:45 Self healing of fire ant aggregations HU, D.L.*; DAVE, T.; PHONEKEO, S; Georgia Institute of Technology, Atlanta hu@me.gatech.edu Fire ants (Solenopsis invicta) link their bodies together to form structures such as rafts, bivouacs and bridges. Such structures are in danger of being damaged by natural disturbances such as passing water […]

Modeling the effect of group size on rheotactic behaviors
Meeting Abstract 115.5 Wednesday, Jan. 7 14:30 Modeling the effect of group size on rheotactic behaviors CHICOLI, A*; PALEY, D.A.; Univ. of Maryland, College Park; Univ. of Maryland, College Park achicoli@umd.edu Many fish exhibit (positive) rheotaxis, a behavior in which fish orient upstream with respect to the flow. Rheotaxis may confer many potential benefits, including energetic cost […]
