Meeting Abstract 52.2 Sunday, Jan. 5 10:15 Genital evolution in bats- a study of glans elaboration ORR, T.J.*; BRENNAN, P.L.R.; UMass Amherst; UMass Amherst tjorr@cns.umass.edu Genitalia are extraordinarily diverse and likely evolve via several processes, primarily sexual selection. The mechanisms include male-male competition (sperm competition), selection for female stimulation (cryptic female choice) or sexually antagonistic coevolution (conflict […]

Does Size Really Matter The Effect of Genital Size on Reproductive Success
Meeting Abstract 52.1 Sunday, Jan. 5 10:00 Does Size Really Matter? The Effect of Genital Size on Reproductive Success DREYER, AP*; SHINGLETON, AW; Michigan State University; Michigan State University dreyerau@gmail.com From flies to spiders and crabs to beetles, genital size remains near constant among individuals in a population despite considerable phenotypic plasticity in body size and the […]
Body condition affects ejaculate traits in a lizard with condition-dependent fertilization success
Meeting Abstract 52.4 Sunday, Jan. 5 11:00 Body condition affects ejaculate traits in a lizard with condition-dependent fertilization success KAHRL, A.F.*; COX, R.M.; University of Virginia afk7df@virginia.edu Sexual selection is predicted to deplete genetic variation in fitness-related traits, but condition-dependence can maintain phenotypic variation in the face of strong selection. Characteristics of the male ejaculate, such as […]

Modularity and Heterochrony in the Adaptive Evolution of the Lateral Line System of Fishes
Meeting Abstract 51.4 Sunday, Jan. 5 11:00 Modularity and Heterochrony in the Adaptive Evolution of the Lateral Line System of Fishes BIRD, NC*; WEBB, JF; University of Rhode Island; University of Rhode Island nathan_bird@mail.uri.edu The ability of different modules to evolve independently is a fundamental concept in organismal evolution. Module independence is critical for local evolutionary changes […]

Development of adipose fin innervation and implications for fin evolution
Meeting Abstract 51.5 Sunday, Jan. 5 11:15 Development of adipose fin innervation and implications for fin evolution. STEWART, TA*; HALE, ME; University of Chicago; University of Chicago tomstewart@uchicago.edu Adipose fins are found on the dorsal surface of many teleost fishes, between the dorsal and caudal fins. They have evolved repeatedly, at least three times in ray-finned fishes. […]
The effect of muscle relaxation rate on tendon recoil during energy dissipating tasks
Meeting Abstract 50.7 Sunday, Jan. 5 11:45 The effect of muscle relaxation rate on tendon recoil during energy dissipating tasks ABBOTT, EM*; AZIZI, E; Univ. of California, Irvine emily.m.abbott@gmail.com Series elastic elements, such as tendons and aponeuroses, can amplify muscle power, minimize energy consumption and limit injury susceptibility. Specifically, during energy dissipating tasks, muscles initially store energy […]
Passive Properties of Anuran Hindlimb Muscles
Meeting Abstract 50.1 Sunday, Jan. 5 10:15 Passive Properties of Anuran Hindlimb Muscles DANOS, N*; AZIZI, E; Univ. of California Irvine; Univ. of California Irvine ndanos@uci.edu Frog muscles are unusually compliant compared to mammalian muscles. An important implication of this muscle property is that frog muscles can be stretched to long lengths and can operate on the […]
