Meeting Abstract 55-3  Sunday, Jan. 5 11:00 – 11:15  A Role of Insulin-Like Growth Factors in Mediating Trade-Offs Between Growth and Reproduction in Painted Turtles ADDIS, AE*; JANZEN, FJ; BRONIKOWSKI, AM; Gonzaga University; Iowa State University; Iowa State University addis@gonzaga.edu A central tenet of life-history theory predicts the existence of energetic trade-offs. A classic example of these […]

Mart�nez del Rio, C.*; Sabat, P.; Schondube, J. E.: Stable Isotope Composition as a Covariate in Comparative Physiology When animals ingest different diets, they must process contrasting arrays of nutrients, electrolytes, toxins and water. Hence, diet is a major determinant of an animal’s digestive and osmoregulatory traits and an important independent variable in comparative studies. […]

RUBEGA, M.A.*; HEATH, K.M.: Skeletal development in hatchling avocets and stilts: the effects of salt stress on growth and ossification. Post-hatching skeletal development in non-galliform precocial birds is less well-known than is embryonic development, and the effects of stress during growth are even less studied. Many studies have shown that high salinity levels are lethal […]

WEINSTEIN, R.B.*; HARTMAN, J.H.: Modeling the intermittent exercise strategy of “Ride and Tie” competition Intermittent exercise is characterized by bouts of exercise alternated with pauses. When exercise bouts are performed at a high intensity, brief pauses provide time for recovery from the preceding exercise bout. In “Ride and Tie”, a competitive sport incorporating intermittent exercise, […]

Sage, R.F.*; Sage, T.L.: Microsites Characteristics of Muhlenbergia richardsonis, an alpine C4 Plant. C4 plants are uncommon in cold environments at high latitude and altitude, and are not generally thought to occur in the alpine tundra. In the White Mountains of California, we found that the C4 grass Muhlenbergia richardsonis commonly occurs in the alpine […]

GUGLIELMO, C.G.*; PIERSMA, T.; WILLIAMS, T.D.: Flight-Induced Muscle Damage And Avian Migration, Evidence From Two Shorebird Species It has often been suggested that birds undergo processes of repair and physiological recovery following long distance flights, however exactly what these processes are remains mostly undescribed. High intensity, long duration exercise is known to cause muscle damage, […]

PACKARD, G.C.*; PACKARD, M.J.: Environmentally Induced Variation in Size and Condition of Hatchling Painted Turtles We manipulated the contents of newly constructed nests of painted turtles (Chrysemys picta) so that each of three nests received two eggs from each of the same five females. The manipulation was replicated on three successive days, thereby yielding a […]
