Roberts, S.A.*; Moore, P.A.; Huber, R.; Heckman, C.; Cayer, M.: Immunocytochemical Localization of Met-enkephalin in Crayfish Eye Stalk Experimental investigation into the effect of chemical signals in the nervous system of crayfish has shown certain neurotransmitters, such as seratonin and dopamine, have the capability of altering the aggressive tendencies of crayfish in a hierarchical community. […]

Hsieh, T.; Rosario, C.; Duan, C.*: INSULIN-LIKE GROWTH FACTOR (IGF) BINDING PROTEIN-5 STIMULATES CELL MOTILITY THROUGH AN IGF-INDEPENDENT MECHANISM THAT MAY INVOLVE IN ITS NUCLEAR TRANSLOCATION Porcine vascular smooth muscle cells (VSMCs) secrete insulin-like growth factor binding protein-5 (IGFBP-5). In this report, we show that IGFBP-5 regulates VSMC motility through an IGF-dependent as well as […]

GAINEY, JR., L.F. *; CHICOINE, D.; WALTON, J.; GREENBERG, M.J.: Hydrogen sulfide potentiates muscle contraction in clam gills When isolated gills of Mercenaria mercenaria are treated with 5-hydroxytryptamine (5HT), the branchial musculature contracts in a dose dependent manner. Moreover, a second application of 5HT at the same concentration produces a larger contraction; this effect is […]

PANKO, L.J.: How to distinguish the basal Triassic cynodonts Galesaurus and Thrinaxodon from one another using rib morphology A peculiar feature of certain non-mammalian cynodonts is their broad, overlapping ribs. Galesaurus and Thrinaxodon have broadened ribs in both thoracic and lumbar regions, though the details of morphology vary along the trunk. In the past, Galesaurus […]

Coombs, S.*; Anderson, E.J.; Braun, C.B.; Grosenbaugh, M.A.: How fish body parts alter local hydrodynamic stimuli to the lateral line. Mottled sculpin (Cottus bairdi), like many fish, use their lateral line system to form hydrodynamic images of the environment. Although these small (~10 cm long), benthic fish inhabit streams and lakes with significant ambient water […]

Gilchrist, M.A.*; Sasaki, A.: Host-Parasite Coevolution based on Models of Within-Host Dynamics Host-Parasite coevolution has long been an area of interest of evolutionary biologists. However, most mathematical models on the evolution of parasite virulence view the host as a static, non-evolving entity. By focusing on the dynamics of the parasite population within a host and […]

BOWDEN, R.M.*; EWERT, M.A.; LIPAR, J.L.; NELSON, C.E.: Hormones in Yolk Layers and Offspring Sex Ratios Vary Seasonally in Turtles The presence of hormones in yolks of freshly laid eggs has recently been described in reptiles. These hormones are probably of maternal origin. Their potential to influence offspring sex may be enhanced by temperature-dependent sex […]

SANTINI, F.: Historical Biogeography of Coral Reefs Organisms: is the Indonesian Region a Center of Origin? Historical biogeography is the discipline concerned with the study of the evolutionary phenomena responsible for the distribution of living organisms in space. I have collected and analyzed phylogenetic hypotheses and distributional data for twelve clades of Indo-Western Pacific coral […]

LOEWEN, M. A.; SAMPSON, S. D.: Hindlimb ontogeny in the Late Jurassic theropod dinosaur Allosaurus fragilis The Cleveland-Lloyd Dinosaur Quarry (CLDQ) of central Utah contains an extensive sample of Allosaurus fragilis, the largest known for any large theropod taxon. This collection, along with isolated articulated specimens, forms the material basis of a study of ontogenetic […]

ANDREWS, A.L.*; HATLE, J.D.; CROWLEY, M.C.; JULIANO, S.A.: Hemolymph protein profiles during egg production in three populations of the Eastern lubber grasshopper Distant populations of a given organism can be predicted to have reproductive physiologies that are adapted to their local environment. For example, to avoid a reproductive output of zero, populations of univoltine species […]
