Temperature gradients in the dorsolongitudinal flight muscles of Manduca sexta may yield functional gradients
Meeting Abstract 17.2 Sunday, Jan. 4 Temperature gradients in the dorsolongitudinal flight muscles of Manduca sexta may yield functional gradients. GEORGE, N.T.*; DANIEL, T.L.; Univ. of Washington, Seattle ntgeorge@u.washington.edu During muscle contraction, heat is produced as chemical energy is converted into mechanical work. Many large insects with active flight muscles use this byproduct to elevate flight muscle […]
Low thermal dependence of elastically-powered movement in salamanders
Meeting Abstract 17.1 Sunday, Jan. 4 Low thermal dependence of elastically-powered movement in salamanders DEBAN, S.M.; Univ. South Florida sdeban@cas.usf.edu Biological springs in musculoskeletal systems provide a range of benefits to organisms including energy recovery, power amplification, improved force control, and expanded functional range of muscles. To test the hypothesis that, in addition, elastic recoil mechanisms extend […]

Compensatory morphological plasticity in response to low protein diets in mice (Mus musculus)
Meeting Abstract 16.1 Sunday, Jan. 4 Compensatory morphological plasticity in response to low protein diets in mice (Mus musculus) DERRICKSON, EM*; MARINELLI, K; Loyola College; Loyola College ederrickson@loyola.edu The protein content of food directly impacts the growth and development of animals. Because low protein diets likely are encountered by omnivorous and herbivorous mammals, mice may have evolved […]
