Evolutionary And Acclimation-Induced Variation In The Heat-Shock Responses Of Congeneric Marine Snails (Genus Tegula) From Different Thermal Habitats: Implications For Limits Of Thermotolerance And Biogeography, Lars Tomanek, George N. Somero
Evolutionary And Acclimation-Induced Variation In The Heat-Shock Responses Of Congeneric Marine Snails (Genus Tegula) From Different Thermal Habitats: Implications For Limits Of Thermotolerance And Biogeography, Lars Tomanek, George N. Somero
Biological Sciences
Heat stress sufficient to cause cellular damage triggers the heat-shock response, the enhanced expression of a group of molecular chaperones called heat-shock proteins (hsps). We compared the heat-shock responses of four species of marine snails of the genus Tegula that occupy thermal niches differing in absolute temperature and range of temperature. We examined the effects of short-term heat stress and thermal acclimation on the synthesis of hsps of size classes 90, 77, 70 and 38 kDa by measuring incorporation of (35)S-labeled methionine and cysteine into newly synthesized proteins in gill tissue. Temperatures at which enhanced synthesis of hsps first occurred …
Lead Binding To Metal Oxide And Organic Phases Of Natural Aquatic Biofilms, Yarrow M. Nelson, Leonard W. Lion, Michael L. Shuler, William C. Ghiorse
Lead Binding To Metal Oxide And Organic Phases Of Natural Aquatic Biofilms, Yarrow M. Nelson, Leonard W. Lion, Michael L. Shuler, William C. Ghiorse
Civil and Environmental Engineering
The role of the composition of surface-coating materials in controlling trace metal adsorption in aquatic environments was investigated using natural biofilms that developed on glass slides in three New York State lakes and a water-supply well. Adsorption isotherms were obtained for Pb binding to each of the biofilms in solutions with defined Pb speciation at 25°C and pH 6.0, with Pb concentrations ranging from 0.2 to 2.0 μM. Adsorption isotherms for Pb binding to laboratory-derived metal oxides and surrogate organic materials were determined under the same conditions. These isotherms, combined with characterization of natural biofilm composition, were used to estimate …

The Edaphic Factor And Patterns Of Variation In Lasthenia Californica (Asteraceae), Nishanta Rajakaruna, Bruce A. Bohm
Biological Sciences
Transectional studies of Lasthenia californica in the Jasper Ridge Biological Preserve (Stanford University) have documented the existence of two races (A and C) based upon flavonoid chemistry, achene morphology, allozymes, and flowering time differences. The two races coexist on a serpentine outcrop and have maintained a sharply defined pattern of distribution for a period of at least 15 yr. The present study has revealed significant differences in the physical and chemical features of the soils harboring the two races. Soils at the lower ends of the transects, where race A plants grow, have higher pH, cation exchange capacity, relative water …

Optical Monitoring And Forecasting Systems For Harmful Algal Blooms: Possibility Or Pipe Dream?, Mark A. Moline, Oscar Schofield, Joe Grzymski, Paul W. Bissett, Gary J. Kirkpatrick, David F. Millie, Collin S. Roesler
Optical Monitoring And Forecasting Systems For Harmful Algal Blooms: Possibility Or Pipe Dream?, Mark A. Moline, Oscar Schofield, Joe Grzymski, Paul W. Bissett, Gary J. Kirkpatrick, David F. Millie, Collin S. Roesler
Biological Sciences
Monitoring programs for harmful algal blooms (HABs) are currently reactive and provide little or no means for advance warning. Given this, the development of algal forecasting systems would be of great use because they could guide traditional monitoring programs and provide a proactive means for responding to HABs. Forecasting systems will require near real-time observational capabilities and hydrodynamic/biological models designed to run in the forecast mode. These observational networks must detect and forecast over ecologically relevant spatial/ temporal scales. One solution is to incorporate a multiplatform optical approach utilizing remote sensing and in situ moored technologies. Recent advances in instrumentation …
Belief Or 'Belief': Rush Rhees On Religious Belief Language, Todd R. Long
Belief Or 'Belief': Rush Rhees On Religious Belief Language, Todd R. Long
Philosophy
The recent book Rush Rhees on Religion and Philosophy contains a stimulating collection of writin~s by Rush Rhees on a variety of topics in the philosophy of religion. Comprising accounts of personal, religious and moral struggles, these essays provide a refreshing change from the often dry, overly technical approach to philosophy writing. Despite spanning more than thirty years, Rhees' s essays disclose a fairly consistent philosophy .of religion with a clear emphasis. Since he was Wittgenstein's student and long-time friend as well as a literary executor ofWittgenstein's writings, it is not surprising that Rhees's comments on the philosophy of religion …
Application Of A Fiber-Reinforced Continuum Theory To Multiple Deformations Of The Annulus Fibrosus, Stephen M. Klisch, Jeffrey C. Lotz
Application Of A Fiber-Reinforced Continuum Theory To Multiple Deformations Of The Annulus Fibrosus, Stephen M. Klisch, Jeffrey C. Lotz
Mechanical Engineering
Accurate tissue stress predictions for the annulus fibrosus are essential for understanding the factors that cause or contribute to disc degeneration and mechanical failure. Current computational models used to predict in vivo disc stresses utilize material laws for annular tissue that are not rigorously validated against experimental data. Consequently, predictions of disc stress resulting from physical activities may be inaccurate and therefore unreliable as a basis for defining mechanical–biologic injury criteria. To address this need we present a model for the annulus as an isotropic ground substance reinforced with two families of collagen fibers, and an approach for determining the …
Bacterial Magnetosomes: Microbiology, Biomineralization And Biotechnological Applications, Dirk Schlϋer, Richard B. Frankel
Bacterial Magnetosomes: Microbiology, Biomineralization And Biotechnological Applications, Dirk Schlϋer, Richard B. Frankel
Physics
Magnetotactic bacteria orient and migrate along geomagnetic field lines. This ability is based on intracellular magnetic structures, the magnetosomes, which comprise nanometer-sized, membrane-bound crystals of the magnetic iron minerals magnetite (Fe3O4) or greigite (Fe3O4). Magnetosome formation is achieved by a mineralization process with biological control over the accumulation of iron and the deposition of the mineral particle with specific size and orientation within a membrane vesicle at specific locations in the cell. This review focuses on the current knowledge about magnetotactic bacteria and will outline aspects of the physiology and molecular biology …

Food Intake Patterns And Gallbladder Disease In Mexican Americans, Marilyn Tseng, Robert F. Devellis, Kurt R. Maurer, Meena Khare, Lenore Kohlmeier, James E. Everhart, Robert S. Sandler
Kinesiology and Public Health
Objective: Results of previous studies on diet and gallbladder disease (GBD), defined as having gallstones or having had surgery for gallstones, have been inconsistent. This research examined patterns of food intake in Mexican Americans and their associations with GBD. Design: Cross-sectional. Subjects: The study population included 4641 Mexican Americans aged 20±74 years who participated in the 1988±94 third National Health and Nutrition Examination Survey (NHANES III). GBD was diagnosed by ultrasound. Food intake patterns were identifed by principal components analysis based on food frequency questionnaire responses. Component scores representing the level of intake of each pattern were categorized into quartiles, …
Makaira Sp., Cf. M. Nigricans Lacépède, 1802 (Teleostei: Perciformes: Istiophoridae) From The Late Miocene, Panama, And Its Probable Use Of The Panama Seaway, Harry L. Fierstine
Makaira Sp., Cf. M. Nigricans Lacépède, 1802 (Teleostei: Perciformes: Istiophoridae) From The Late Miocene, Panama, And Its Probable Use Of The Panama Seaway, Harry L. Fierstine
Biological Sciences
A nearly complete rostrum (USNM 358534) similar in morphology to the extant bluc marlin, Makaira nigricans Lacepede 1802, is identified from the GaUln Formation (late Miocene, Panama). Identification is based on comparison with a large series of Recent istiophorid species and with fossil species of the genus Makaira. The Gatlin specimen and additional examples from other fossil vertebrates provide evidence that the ancient Panama Seaway probably was a travel route between the Atlantic and Indo-Pacific for large marine vertebrates during the middle Miocene to earliest Pliocene. This is the first record of an istiophorid billfish from the Gatlin Fonnation and …
Variation And Repeatability Of Calling Behavior In Crickets Subject To A Phonotactic Parasitoid Fly, Gita R. Kolluru
Variation And Repeatability Of Calling Behavior In Crickets Subject To A Phonotactic Parasitoid Fly, Gita R. Kolluru
Biological Sciences
Male Teleogryllus oceanicus (Orthoptera: Gryllidae) produce a conspicuous calling song to attract females. In some populations, the song also attracts the phonotactic parasitoid fly Ormia ochracea (Diptera: Tachinidae). I examined the factors affecting calling song by characterizing the calling behavior of caged crickets from an area where the fly occurs. Calling activity (proportion of time spent calling) was repeatable and a significant predictor of female attraction. However, calling activity in the parasitized population was lower than in an unparasitized Moorea population (Orsak, 1988), suggesting a compromise between high activity to attract females and low activity to avoid flies. Calling activity …
