OSBORN, Dawn: Rock type: Does it matter for intertidal community ecology? The importance of substrate type on community ecology has been studied infrequently, partly because geologic differences generally occur over large spatial scales and transplantation studies are difficult. The extensive anthropogenic armoring of the shorelines provides an unusual opportunity to determine the effect of differing […]

CASOTTI, G.; BRAUN, E.J.: Protein localization in avian urine spheres Uricotelic vertebrates excrete uric acid in the form of spheres (1-15 �m in size) in their urine. In addition to uric acid, the spheres contain protein and inorganic ions. In an attempt to determine how they are formed within the nephron, we processed spheres for […]

BELDEN, L.K.; BLAUSTEIN, A.R.: Population differences in sensitivity to UV-B radiation for larval long-toed salamanders Due to ozone depletion, the intensity of ultraviolet-B radiation (UV-B; 280 – 315 nm) at the Earth’s surface is increasing. UV-B penetrates some aquatic habitats to biologically significant depths and can alter life histories of aquatic organisms, including algae, zooplankton, […]

AVENI-DEFORGE, K*; WETHEY, D.S.: Physical constraints on zonation patterns of the barnacle _Chthamalus fragilis_ Zonation patterns in the rocky intertidal are linked to microclimates. The upper distribution limits of many species in the intertidal are determined by intolerance to the microclimate conditions rather than absolute tidal height. The barnacle Chthamalus fragilis is common to the […]

HAMDOUN, A. M.; CHERR, G. N.: Phenotypic plasticity of HSP70 and HSP70 gene expression in the Pacific oyster (Crassostrea gigas): Implications for Resting Thermal Limits and Induction of Thermal Tolerance Heat shock responses are thought to play a major role in determining maximal thermal limits and distribution of sessile intertidal bivalves. We have found that […]

FAULKES, Z.: Parallelism in digging behaviour in two distantly related decapod crustaceans Walking and swimming are the most common forms of locomotion used routinely by decapod crustaceans, but some have evolved ways of locomoting through substrates, notably sand. Two such digging species, of different infraorders, are spanner crabs (Ranina ranina; Brachyura) and spiny sand crabs […]

MIDDLE, L.B.; BARNES, B.M.: Overwintering physiology of the wood frog, Rana sylvatica, in Interior Alaksa The wood frog, Rana sylvatica, is one of the most northerly distributed amphibian species with populations ranging up to 100 miles north of the Arctic Circle. The key to its survival at high latitudes is the ability to survive extracellular […]

OLSON, J.M.; RICKLEFS, R.E.: Ontogenic changes in metabolic capabilities and shivering thermogenesis in the willow ptarmigan The willow ptarmigan is a resident of arctic and subarctic regions routinely subjected to cold, wet conditions, even during the short breeding season. As a precocial species, newly hatched and young ptarmigan chicks forage on their own soon after […]

LEE, MJ*; ANDERSON, CW: Neuroanatomical evidence for integration of olfaction into the frog feeding motor pattern generator To understand the neural control of movement, it is critical to understand the anatomy of feedback mechanisms that coordinate movement with environmental and postural changes. The specific goal of this project is to identify olfactory projections into the […]

SWEENEY, A.M.; BALSER, E.J.: Neural Hemoglobin in the Polychaete Glycera dibranchiata: Evidence for a Molecular Funnel Glycera dibranchiata is a common polychaete worm that has a large fluid-filled body cavity, called a coelom, which it uses as a hydrostatic skeleton and as a means of circulating hemoglobin-containing cells (hemocytes) for respiration. The coelomic hemoglobins of […]
