Meeting Abstract 67-5  Sunday, Jan. 5 14:30 – 14:45  A Transition to XY Sex Chromosomes Associated with Y-linked Duplication of a Male Hormone Gene in a Terrestrial Isopod RUSSELL, A; BORRELLI, S; FONTANA, R; LARICCHIUTA, J; PASCAR, J; BECKING, T; GIRAUD, I; CORDAUX, R; CHANDLER, CH*; SUNY Oswego; SUNY Oswego; SUNY Oswego; SUNY Oswego; SUNY Oswego, Syracuse […]

Pabst, D.A.*; Koopman, H.N.; Rommel, S.A.; Potter, C.W; Read, R.J.; McLellan, W.A.: Ontogenetic allometry and body composition of harbor porpoises Phocoena phocoena from the western north Atlantic North Atlantic harbor porpoises face considerable energetic challenges, as they are relatively small mammals with an intense reproductive schedule and a cold-water habitat. We describe post-natal growth of […]

Prum, R.O.*; Williamson, S.: Models of the developmental determination of feather shape and pigmentation pattern. We present the first explicit theories of the growth of feather shape (the outline of a pennaceous vane) and the determination of within feather pigmentation pattern. The growth of feathers is simulated with a mathematical model based on six growth […]

ESPINOZA, N.R.: Effects of developmental temperature on musculoskeletal growth and jumping performance in the treefrog Hyla chrysoscelis. Several vertebrate species have shown ontogenetic adjustments in the form and material properties of the growing musculoskeletal system to allow the same level of locomotor performance in juveniles and adults. The rate of growth and amount of time […]

ZELDITCH, M.L.*; SHEETS, H.D.; FINK, W.L.: Conservative ontogenetic trajectories: artifacts or data? Most comparative studies support the hypothesis that ontogenetic trajectoriesare historically conservative. The primary basis for this generalization is the typically high correlation between ontogenetic allometric vectors, a measure of their similarity. More than 76% of 233 comparisons yield vector correlations as high as […]

Peter Larson: Chondrocranial development in larval Rana sylvatica (Anura: Ranidae): A morphometric analysis of cranial allometry and ontogenetic shape change This study provides baseline quantitative data on the morphological development of the chondrocranium in a larval anuran. Both linear and geometric morphometric methods are used to quantitatively analyze size related shape change in a complete […]

HARTZLER, L.K.*; HICKS, J.W.; BENNETT, A.F.; STINNER, J.N.: Role of Temperature and pH on Enzyme Activity in Air-breathing Ectotherms Maintenance of the integrity of functional groups in enzymes has been proposed as a key reason for regulation of acid-base changes during changes in body temperature. As pH of tissue changes, different titratable groups are affected […]

REESE,, S.A.*; CROCKER,, C.E.; JACKSON,, D.C; ULTSCH, G.R.: Physiology of overwintering in Chrysemys picta picta from Georgia Eastern painted turtles (Chrysemys picta picta) from Georgia were submerged in anoxic and normoxic water at 3°C. Plasma PO2, PCO2, pH, [Na+], [Cl–], [K+], total Mg, total Ca, lactate, glucose, and osmolality were measured from turtles submerged for […]

HARRISON, J.F.; LAFRENIERE, J.; HARTUNG, D.A.; GREENLEE, K.; KIRKTON, S.D.: Ontogeny effects on the diffusive and convective conductance of abdominal and leg trachea in Schistocerca americana grasshoppers Several authors have proposed that evolution of gigantic insects in the late Paleozoic may have been made possible by atmospheric hyperoxia. Is there any evidence from extant insects […]
