P.; Santa Clara University; Santa Clara University; Santa Clara University: Effects of temperature on performance and fitness of two species of California willow beetle We compared effects of temperature stress on running speed, fecundity and mating frequency for two species of California leaf beetle, Chrysomela schaefferi and […]

CLAUSSEN, D.L.*; SNASHALL, J.; BARDEN, C.; Miami Univ., Oxford, OH; Miami Univ., Oxford, OH; Miami Univ., Oxford, OH: Effects of slope, substrate, and temperature on forces associated with locomotion of the ornate box turtle, Terrapene ornata In spite of several studies of the locomotor performances of turtles, we as yet know relatively little about the […]

HARDY, KM; KINSEY, ST; Univ. of North Carolina, Wilmington ; Univ. of North Carolina, Wilmington: Effects of fiber size on post-contractile phosphagen resynthesis in crustacean muscle ABSTRACT Fast-twitch muscle fibers of the juvenile blue crab, Callinectes sapidus, have diameters that are < 100 μm, which is typical of most cells. However, muscle fibers of the […]

CULLUM, A.J.*; GONSALVES, W.; Creighton University, Omaha, NE; Creighton University, Omaha, NE: Effects of developmental temperature on growth in Teleogryllus oceanicus: a test of acclimation hypotheses The capacity of an animal to acclimate to changes in environmental factors such as temperature may have potentially significant fitness consequences. One long-held assumption was that such consequences would […]

WATKINS, T.B.; AWANTANG, G.; EAGAR, T.C.; Macalester College, St. Paul MN: Effects of Pre- and Post-Hatching Temperature on Locomotor Performance and Thermal Preference of Tadpoles The temperature at which the eggs of ectothermic vertebrates incubate can influence several phenotypic traits of offspring. Most studies of this phenomenon have examined only the direct effects of incubation […]

PACE, C. M.; GIBB, A. C.; Northern Arizona University; Northern Arizona University: Do mudskippers really �crutch�? Testing the inverted pendulum model in an amphibious fish. The mudskipper is an amphibious fish that has the ability to locomote on land. Like most terrestrial vertebrates, mudskippers use their limbs to overcome gravity and propel their body forward. […]
