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 […]

Nitrogen solubility related to lipid composition in toothed whale fats
Meeting Abstract 113.6 Tuesday, Jan. 7 11:45 Nitrogen solubility related to lipid composition in toothed whale fats LONATI, G.L.*; WESTGATE, A.J.; KOOPMAN, H.N.; UNC, Wilmington; UNC, Wilmington; UNC, Wilmington GLL9008@uncw.edu Nitrogen (N2) dynamics are physiologically important for air-breathing divers, as N2 inhaled at the surface can saturate fatty tissues that receive blood flow during dives. Toothed whales […]
