Meeting Abstract P1.178 Wednesday, Jan. 4 Use of preferred escape trajectories in Bluegill sunfish (Lepomis macrochirus) ELLERBY, D.J.; HITCHCOCK, A.C.*; Wellesley College; Wellesley College ahitchco@wellesley.edu The escape response of a fish must be both rapid and unpredictable to avoid predation. Movement directed away from the predator would seem ideal; however, a fixed escape strategy would allow predators […]

Uncovering the molecular basis of dispersed photoreception in the cephalopod, Octopus bimaculoides
Meeting Abstract P1.125 Wednesday, Jan. 4 Uncovering the molecular basis of dispersed photoreception in the cephalopod, Octopus bimaculoides RAMIREZ, M. Desmond*; OAKLEY, Todd H.; Univ. of California, Santa Barbara; Univ. of California, Santa Barbara ramirez@lifesci.ucsb.edu Where do the molecular components of complex traits come from? Do they arise de novo, or are they co-opted from existing systems? […]

Thermal acclimation affects the aerobic scope of hissing cockroaches
Meeting Abstract P1.204 Wednesday, Jan. 4 Thermal acclimation affects the aerobic scope of hissing cockroaches WISE, Kelsey L*; GRAY, Emilie M; Colorado College; Colorado College kelsey.wise@coloradocollege.edu The “hotter is better” hypothesis states that the rate-depressing effects of low temperature cannot be compensated by acclimation or adaptation. In the present study we test this hypothesis by using metabolic […]

The relationship between testosterone and aggressive phenotype in male song sparrows (Melospiza melodia )
Meeting Abstract P1.47 Wednesday, Jan. 4 The relationship between testosterone and aggressive phenotype in male song sparrows (Melospiza melodia ) SEWALL, K. B.*; NOWICKI, S.; Duke University; Duke University k.sewall@duke.edu Male songbirds face a trade-off between providing parental care and seeking mates. Individuals may resolve this trade-off differently, potentially generating equally adaptive paternal and aggressive male behavioral […]
The range of variation in pedal phalangeal proportions increases over the evolution of the avian lineage
Meeting Abstract P1.49 Wednesday, Jan. 4 The range of variation in pedal phalangeal proportions increases over the evolution of the avian lineage LEARY, Brian P.*; KAVANAGH, Kathryn; University of Massachusetts Dartmouth; University of Massachusetts Dartmouth bleary@umassd.edu The proportions of the pedal digit phalanges of modern birds have been found to be predictive of their function. Ratites […]
