The Heat-Shock Response: Its Variation, Regulation And Ecological Importance In Intertidal Gastropods (Genus Tegula), Lars Tomanek
The Heat-Shock Response: Its Variation, Regulation And Ecological Importance In Intertidal Gastropods (Genus Tegula), Lars Tomanek
Biological Sciences
The enhanced synthesis of heat-shock proteins (hsps), called the heat-shock (or stress) response, is activated when environmental stress denatures proteins. Hsp synthesis is activated at the upper temperatures of an organism's thermal range and is therefore thought to be critical for enhancing thermal tolerance limits in ectothermic animals. Here I show that the two temperate sister species T. brunnea and T. montereyi that occupy the subtidal and low-intertidal zone differ from the low- to mid-intertidal T. funebralis (and the subtropical mid-intertidal T. rugosa) in (i) heat tolerance, (ii) the onset temperature of their main hsp, hsp70 (70 kDa), (iii) …

Biological Sciences
This review summarizes a collection of lactic acid bacteria that are now undergoing genomic sequencing and analysis. Summaries are presented on twenty different species, with each overview discussing the organisms fundamental and practical significance, environmental habitat, and its role in fermentation, bioprocessing, or probiotics. For those projects where genome sequence data were available by March 2002, summaries include a listing of key statistics and interesting genomic features. These efforts will revolutionize our molecular view of Gram-positive bacteria, as up to 15 genomes from the low GC content lactic acid bacteria are expected to be available in the public domain by …

Some Thoughts On Human Nature: A Discussion Of Human Strenghts And Weaknesses, Jens G. Pohl
Some Thoughts On Human Nature: A Discussion Of Human Strenghts And Weaknesses, Jens G. Pohl
Collaborative Agent Design (CAD) Research Center
This paper attempts to explore the behavioral characteristics of human beings from a point of view that is not based on inter-human comparisons, but on an examination of the intrinsic physical, biological, intellectual, emotional, and social characteristics of this species. It is argued that the experience-based nature of the human cognitive system greatly reduces our ability to adapt to changes in our environment, exploit opportunities, and create new knowledge. A fundamental biological survival instinct drives the human being to seek a level of certainty and security that is irreconcilable with a continuously changing and largely unpredictable environment. The symptoms of …

An Ecological Basis For Managing Giant Sequoia Ecosystems, Douglas D. Piirto, Robert R. Rogers
An Ecological Basis For Managing Giant Sequoia Ecosystems, Douglas D. Piirto, Robert R. Rogers
Natural Resources Management and Environmental Sciences
A strategy for management of giant sequoia groves is formulated using a conceptual framework for ecosystem management recently developed by Region Five of the USDA Forest Service. The framework includes physical, biological, and social dimensions. Environmental indicators and reference variability for key ecosystem elements are discussed in this paper. The selected ecosystem elements include: 1) attitudes, beliefs, and values; 2) economics and subsistence; 3) stream channel morphology; 4) sediment; 5) water; 6) fire; 7) organic debris; and 8) vegetation mosaic. Recommendations are made for the attributes of environmental indicators that characterize these elements. These elements and associated indicators will define …
Autoregressive Moving Average Models Of Crown Profiles For Two California Hardwood Species, Samantha J. Gill, Gregory S. Biging
Autoregressive Moving Average Models Of Crown Profiles For Two California Hardwood Species, Samantha J. Gill, Gregory S. Biging
Natural Resources Management and Environmental Sciences
Time-series Autoregressive Moving Average (ARMA) models were employed to model tree crown profiles for two California hardwood species (blue oak and interior live oak). There are three major components of these models: a polynomial trend, an ARMA model, and unaccounted for variation. The polynomial trend was used to achieve a stationary series. For these crown profiles, the use of a quadratic trend resulted in a stationary series for 60% of the profiles. A cubic trend was used for another 23%, and a quartic for 7%. It was found that 80% of the tree crown profiles could be modeled using a …

Effects Of Temperature, Epinephrine And Ca2+ On The Hearts Of Yellowfin Tuna (Thunnus Albacares), Jason M. Blank, Jeffery M. Morrissette, Peter S. Davie, Barbara A. Block
Biological Sciences
Tuna are endothermic fish with high metabolic rates, cardiac outputs and aerobic capacities. While tuna warm their skeletal muscle, viscera, brain and eyes, their hearts remain near ambient temperature, raising the possibility that cardiac performance may limit their thermal niches. We used an in situ perfused heart preparation to investigate the effects of acute temperature change and the effects of epinephrine and extracellular Ca2+ on cardiac function in yellowfin tuna (Thunnus albacares). Heart rate showed a strong temperature-dependence, ranging from 20 beats min-1 at 10 °C to 109 beats min-1 at 25 °C. Maximal stroke …

Litr, A New Transcriptional Activator In Vibrio Fischeri, Regulates Luminescence And Symbiotic Light Organ Colonization, Pat Fidopiastis, Carol M. Miyamoto, Michael G. Jobling, Edward A. Meighen, Edward G. Ruby
Biological Sciences
Vibrio fischeri is the bacterial symbiont within the light-emitting organ of the sepiolid squid Euprymna scolopes . Upon colonizing juvenile squids, bacterial symbionts grow on host-supplied nutrients, while providing a bioluminescence that the host uses during its nocturnal activities. Mutant bacterial strains that are unable to emit light have been shown to be defective in normal colonization. A 606 bp open reading frame was cloned from V. fischeri that encoded a protein, which we named LitR, that had about 60% identity to four related regulator proteins: Vibrio cholerae HapR, Vibrio harveyi LuxR, Vibrio parahaemolyticus OpaR and Vibrio vulnificus SmcR.

Comparative Phenotypic, Molecular, And Virulence Characterization Of Vibrio Parahaemolyticus O3:K6 Isolates, P.S. Marie Yeung, Micaela C. Hayes, Angelo Depaola, Charles A. Kaysner, Laura Kornstein
Biological Sciences
Historically, Vibrio parahaemolyticus infections have been characterizedby sporadic cases caused by multiple, diverse serotypes. However,since 1996, V. parahaemolyticus serotype O3:K6 strains havebeen associated with several large-scale outbreaks of illness,suggesting the emergence of a "new" group of organisms withenhanced virulence. We have applied three different molecularsubtyping techniques to identify an appropriate method for differentiatingO3:K6 isolates from other serotypes. Pulsed-field gel electrophoresis(PFGE) following NotI digestion differentiated seven closelyrelated subtypes among O3:K6 and related strains, which weredistinct from PFGE patterns for non-O3:K6 isolates. Ribotypingand tdh sequencing were less discriminatory than PFGE, but furtherconfirmed close genetic relationships among recent O3:K6 isolates.In vitro adherence …

The Production Of Communication Signals At The Air–Water And Water–Substrate Boundaries, Sean C. Lema, John T. Kelly
The Production Of Communication Signals At The Air–Water And Water–Substrate Boundaries, Sean C. Lema, John T. Kelly
Biological Sciences
The 2 interfaces of the aquatic environment, the boundary between air–water and water–substrate, have distinctive physical characteristics that facilitate the production of communication signals. Recent evidence suggests that animals living on or near these boundaries use the interface to generate signals in 2 ways: (a) by producing a signal that propagates along the interface or (b) by producing a signal at the interface that is transmitted and detected within 1 of the component media. By examining the diversity of behaviors used to produce signals at these boundaries, the authors illustrate how human perception of these environments may cause researchers to …
Dietary Patterns And Prostate Cancer Risk In The Nhefs Cohort, Marilyn Tseng
Dietary Patterns And Prostate Cancer Risk In The Nhefs Cohort, Marilyn Tseng
Kinesiology and Public Health
We examined the association between dietary patterns and prostate cancer risk using data from the first National Health and Nutrition Examination Epidemiologic Follow-up Study. The study population included 3,779 men followed 1982-4 to 1992, with 136 prostate cancer cases identified during the follow-up. Principal components analysis on responses to a lOS-item diet questionnaire in 1982-84 was used to identify dietary patterns, and scores representing level of intake of each pattern were categorized into tertiles. Three distinct patterns were identified: a vegetable-fruit pattern, a red meat-starch pattern characterized by intake of beef, pork, potatoes, and sweets, and a southern pattern characterized …
Combining Behavioral And Pharmacological Treatments For Obesity, Suzanne Phelan, Thomas A. Wadden
Combining Behavioral And Pharmacological Treatments For Obesity, Suzanne Phelan, Thomas A. Wadden
Kinesiology and Public Health
Weight-loss medications are currently recommended for use only as an adjunct to diet, exercise, and behavior modification. Little, however, is known about the benefits of combining behavioral and pharmacological therapies or about the mechanisms that would make these combined approaches more effective than either used alone. This article reviews the effects of adding pharmacotherapy (i.e., principally sibutramine and orlistat) to a modest program of lifestyle modification. Studies revealed that the addition of medication typically improved short- and long-term weight loss compared with lifestyle modification alone. The best results, however, were obtained when medications were combined with an intensive, group program …
