DRABEK, C.M.; BURNS, J.M.; Whitman College, Walla Walla, Washington; University of Alaska Anchorage: Heart and aorta morphology of the deep diving hooded seal (Cystophora cristata) An investigation of the heart morphology of eight male and 15 female hooded seals (Cystophora cristata) revealed that the heart is proportionately large and the aortic bulb is larger than […]

WAGNER, C.A.; LI, S.; FRIESEN, J.A.; BORST, D.W.; Illinois State University, Normal: HMG-CoA Reductase acitivity in the fat body of the lubber grasshopper, Romalea microptera. Isoprenoid dolichols are associated with the glycosylation of insect vitellogenin (Vg), a major yolk protein produced by the fat body (FB). Therefore, we studied the activity of 3-hydroxy-3-methylglutaryl-coenzyme A reductase […]

MARTINEZ, V.G.; ZORAN, M.J.; Texas A&M University; Texas A&M University: Giant Axon Morphallaxis During Segmental Regeneration Of Lumbriculus variegatus Lumbriculus variegatus, a freshwater oligochaete worm, demonstrates patterned regeneration of lost body parts and morphallaxis of original body parts (neural reflexes and behavior) following segmental amputation. Axial gradients in neurophysiological function of medial and lateral giant […]

CLOTFELTER, E.C.*; INGHAM, R.R.; GESUALDI, D.A.; Providence College; Providence College; Providence College: Genistein exposure and growth of fathead minnows We examined the effects of the isoflavone genistein on the growth and development of the fathead minnow, Pimephales promelas. Using a static-renewal test design, minnows were exposed for 96 hours to genistein dissolved in water at […]

STEYERMARK, A.C.*; DIAMOND, J.; University of California, Los Angeles; University of California, Los Angeles: Functional design of the gut: nitrogen processing Case studies in physiology and anatomy suggest that the design of cells, tissues, and organs is quantitatively adjusted to functional needs, such that the body uses available materials and space efficiently. Series pathways in […]

OWERKOWICZ, T.; MUNNS, S.; HICKS, J.W.; Harvard University, Cambridge, MA; Univ. of California, Irvine; Univ. of California, Irvine: Function of the postpulmonary septum in lung ventilation in Varanus. Monitor lizards (genus Varanus) are unique among the Squamates in possessing a postpulmonary septum (PPS). The PPS is a nonmuscular membrane, adhering closely to the caudoventral surface […]

KAJIURA, S.M.; University of California, Irvine: Function of the Hammerhead Shark Cephalofoil It has been supposed that the evolution of the wing-like cephalofoil head of hammerhead sharks (Chondrichthyes, Sphyrnidae) was driven either by sensory systems or hydrodynamic concern; however there is little experimental evidence in favor of either group of hypotheses. The scalloped hammerhead shark, […]

HARMS, H. K.; PAITZ, R. T.; JANZEN, F. J.; Iowa State University; Iowa State University; Iowa State University: From microsatellites to satellites: A multifaceted look at Blanding�s turtles in Iowa Humans have dramatically altered the landscape over the past two centuries. Nowhere is this more apparent than in the state of Iowa, where 91% of […]

MELLARD, J. M.; LOUDON, C. *; University of Kansas: Flexural stiffness of bee antennae Mechanically, insect antennae may be considered as cantilever beams, as they are supported on one end (where they join the head) and project into space. These sensory structures are often long and cylindrical, support their own weight, and respond to mechanical […]

DEWITTE-ORR, S.J.*; BOLS, N.C.; University of Waterloo, Waterloo, Ontario; University of Waterloo, Waterloo, Ontario: Expression of Antiviral Genes in Different Rainbow Trout Cell Lines Six antiviral genes whose expression is regulated by type 1 interferon were investigated by RT-PCR in several rainbow trout cell lines after exposure to polyinosinic:cytidylic acid (poly IC). Poly IC is […]
