SECOR, S.M.; Univ. of Alabama, Tuscaloosa: Allometry of SDA, scaling the metabolic response to digestion The attention on the allometric effects of body mass on metabolism has predominately been focused on basal (or standard) and maximum metabolic rates. The growing interest in the metabolic states associated with meal digestion warrants an investigation of their allometric […]

HILL, P.S.M.; Univ. of Tulsa, Oklahoma USA: Surface opening variations, dominant frequency and amplitude of song in the prairie mole cricket Mole crickets in the Orthopteran family Gryllotalpidae are known for their digging forelimbs and their singing from specialized burrows they have constructed in the soil. Few descriptions of singing, or acoustic, burrows are available […]

FALLAHPOUR, Kamelia; ESPINOZA, Robert E.; California State Univ. Northridge; California State Univ. Northridge: Female breeding coloration as a signal for mate selection: not such a bright idea after all? Breeding coloration is phylogenetically widespread in lizards and known to influence mate choice in both sexes. Female breeding coloration (bright yellow, orange, or red) is rare, […]

GRILLIOT, M.E.*; BURNETT, S.C.; MENDON�A, M.T.; Auburn University, Auburn; Clayton College &State University, Morrow; Auburn University, Auburn: Does reproductive state affect echolocation signals in Eptesicus fuscus: a preliminary study? Ultrasound is a widely used acoustical method for social communication, as well as for navigation and foraging. Although bats are well known for their use of […]

GREENE, M. J.; GORDON, D.M.; University of Colorado at Denver; Stanford University: Cuticular hydrocarbons act as cues in the interaction network regulating harvester ant task allocation Social insect colonies perform a variety of tasks, such as foraging, nest construction and brood care. Task allocation is the process that adjusts the numbers of workers performing each […]

SWARTZ, S.M.; KAY, N.; MIDDLETON, K.M.; BLUME, J. A.; Brown University, Providence, RI; Brown University, Providence, RI; Brown University, Providence, RI; Brown University, Providence, RI: The role of thickness and curvature in dictating subchondral bone stresses in mammalian joints Most analyses of the design of mammal limb bones focus on the compact bone shaft or […]

DEVLIN, M.J.*; LIEBERMAN, D.E.; OLSEN, B.R.; FUKAI, N.; Harvard University; Harvard University; Harvard Medical School; Harvard Medical School: The role of estradiol in mechanotransduction Despite evidence that mechanical loads can induce diaphyseal bone growth, the mechanisms of mechanotransduction in growing bone are poorly understood. One hypothesis is that hormone levels affect osteoblast response to mechanical […]

MAIN, R.P.*; BIEWENER, A.A.; Harvard University; Harvard University: Ontogenetic patterns of bone strain in the emu femur: Do bone strains remain similar as animals grow? Vertebrates vary in size, both through ontogeny and across phylogenetically different taxa. As animals grow through ontogeny, not only do the physical demands placed upon the skeleton change, but depending […]

LEE, A.H.*; ESPINOZA, N.; BLOB, R.W.; Univ. of California, Berkeley; Erskine College; Clemson Univ.: Locomotor bone strain and ontogenetic histology of the humerus in Alligator mississippiensis Recent studies suggest the state and magnitude of strain strongly correlate with the microstructural organization of a limb bone. That correlation has been well tested in bones of animals […]
