Spatial Variation In The Chemical Composition Of Natal Otholiths From A Reef Fish In The Galápagos Islands, Benjamin I. Ruttenberg, Robert R. Warner Dec 2006

Spatial Variation In The Chemical Composition Of Natal Otholiths From A Reef Fish In The Galápagos Islands, Benjamin I. Ruttenberg, Robert R. Warner

Biological Sciences

Over the past decade, researchers have used variation in the chemical composition of fish otoliths (earstones) to address a number of ecological questions, such as stock assessment and assessing rates of movement of individuals among habitats or life-history stages. However, these methods have yet to be applied successfully to the study of larval connectivity, a major unanswered question in marine ecology. Accomplishing this task requires a reference collection of pre-pelagic natal otoliths and accurate measurement of the chemical signatures of otoliths cores of recruits. We analyzed the chemical composition of natal otoliths from near-term benthic eggs of a damselfish (Stegastes ...


Improved Monitoring Of Habs Using Autonomous Underwater Vehicles (Auv), Ian C. Robbins, G. J. Kirkpatrick, Shelley M. Blackwell, J. Hillier, Charles A. Knight, Mark A. Moline Dec 2006

Improved Monitoring Of Habs Using Autonomous Underwater Vehicles (Auv), Ian C. Robbins, G. J. Kirkpatrick, Shelley M. Blackwell, J. Hillier, Charles A. Knight, Mark A. Moline

Biological Sciences

Blooms of toxic algae are increasing in magnitude and frequency around the globe, causing extensive economic and environmental impacts. On the west coast of Florida, blooms of the toxic dinoflagellate Karenia brevis (Davis) have been documented annually for the last 30 years causing respiratory irritation in humans, fish kills, and toxin bioaccumulation in shellfish beds. As a result, methods need to be established to monitor and predict bloom formation and transport to mitigate their harmful effects on the surrounding ecosystems and local communities. In the past, monitoring and mitigation efforts have relied on visual confirmation of water discoloration, fish kills ...


A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores Dec 2006

A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores

Dairy Science

The use of a ceramic microfiltration (MF) membrane for the fractionation of buttermilk and whey buttermilk obtained from pilot scale churning of cream and whey cream from industrial sources has been studied. Whey buttermilk contained comparable amounts of phospholipids compared to regular buttermilk but its protein content was lower due to the absence of caseins. However, it was found that lipid content of whey cream did vary significantly between lots resulting in important variations in the fat content of whey buttermilk. A twofold MF concentration of regular buttermilk doubled its phospholipids content whereas that of whey buttermilk was increased by ...


Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong Dec 2006

Influence Of Ph And Heat Treatment Of Whey On The Functional Properties Of Whey Protein Concentrates In Yoghurt, Isabelle Sodini, Jerry Mattas, Phillip S. Tong

Dairy Science

Our aim was to investigate how two conditions of whey processing, pH and heat treatment, affect the physical properties of stirred yoghurts fortified to 45 g protein kg−1 with whey protein concentrates (WPC). Cheddar whey was heated at pH 6.4 or pH 5.8 at 72 °C for 15 s, eventually heated further at 82 or 88 °C for 78 s, ultrafiltered, and spray dried. Resulting WPC contained 38% protein; the denaturation level of the whey protein was 10–53%. There were significant (P


Girls’ Dairy Intake, Energy Intake, And Weight Status, Laura M. Fiorito, Alison K. Ventura, Diane C. Mitchell, Helen Smiciklas-Wright, Leann L. Birch Nov 2006

Girls’ Dairy Intake, Energy Intake, And Weight Status, Laura M. Fiorito, Alison K. Ventura, Diane C. Mitchell, Helen Smiciklas-Wright, Leann L. Birch

Kinesiology

We explored the relationships among girls’ weight status, dairy servings, and total energy intake. The hypothesis that consuming dairy could reduce risk for overweight was evaluated by comparing energy intake and weight status of girls who met or consumed less than the recommended three servings of dairy per day. Participants included 172 11-year-old non-Hispanic white girls, assessed cross-sectionally. Intakes of dairy, calcium, and energy were measured using three 24-hour recalls. Body mass index and body fat measures from dual-energy x-ray absorptiometry were obtained. Because preliminary analyses suggested systematic underreporting of energy intake, the relationships among dairy servings and measures of ...

Television Viewing And Long-Term Weight Maintenance: Results From The Natinoal Weight Control Registry, Douglas A. Raynor, Suzanne Phelan, James O. Hill, Rena R. Wing

Kinesiology

Objective: To examine the role of television (TV) viewing in long-term maintenance of weight loss.
Research Methods and Procedures: All subjects (N = 1422) were enrolled in the National Weight Control Registry (NWCR), a national sample of adults who have maintained a minimum weight loss of 13.6 kg for at least 1 year. Participants self-reported the average number of hours of weekly TV viewing at entry into the NWCR and at a 1-year follow-up. Cross-sectional and prospective analyses were performed to determine the frequency of TV viewing and the extent to which TV viewing was independently associated with weight regain ...


Environmental Rearing Conditions Produce Forebrain Differences In Wild Chinook Salmon Oncorhynchus Tshawytscha, R. L. Kihslinger, Sean C. Lema, G. A. Nevitt Oct 2006

Environmental Rearing Conditions Produce Forebrain Differences In Wild Chinook Salmon Oncorhynchus Tshawytscha, R. L. Kihslinger, Sean C. Lema, G. A. Nevitt

Biological Sciences

Recent studies suggest that hatchery-reared fish can have smaller brain-to-body size ratios than wild fish. It is unclear, however, whether these differences are due to artificial selection or instead reflect differences in rearing environment during development. Here we explore how rearing conditions influence the development of two forebrain structures, the olfactory bulb and the telencephalon, in juvenile Chinook salmon (Oncorhynchus tshawytscha) spawned from wild-caught adults. First, we compared the sizes of the olfactory bulb and telencephalon between salmon reared in a wild stream vs. a conventional hatchery. We next compared the sizes of forebrain structures between fish reared in an ...

The Effects Of Carotenoid And Food Availability On Resistance To A Naturally Occurring Parasite (Gyrodactylus Turnbulli) In Guppies (Poecilia Reticulata), Gita R. Kolluru, Gregory F. Grether, Sandra H. South, Eric Dunlop, Andrea Cardinali, Linda Liu, Andreah Carapiet Oct 2006

The Effects Of Carotenoid And Food Availability On Resistance To A Naturally Occurring Parasite (Gyrodactylus Turnbulli) In Guppies (Poecilia Reticulata), Gita R. Kolluru, Gregory F. Grether, Sandra H. South, Eric Dunlop, Andrea Cardinali, Linda Liu, Andreah Carapiet

Biological Sciences

Dietary carotenoids have been shown to confer immunological benefits to some species of animals in which males also use these pigments to attract mates. Thus, the potential exists for an allocation trade-off between the sexual and immunological functions of carotenoids. Food availability may also influence immune system function. The present study examined the effects of carotenoid and food availability on the resistance of male guppies (Poecilia reticulata Peters) from four wild populations to the parasite Gyrodactylus turnbulli Harris. Intermediate levels of carotenoid ingestion resulted in the lowest parasite loads, which suggests that carotenoids strengthen parasite resistance at low levels but ...


Testing An Ecophysiological Mechanism Of Morphological Plasticity In Pupfish And Its Relevance To Conservation Efforts For Endangered Devils Hole Pupfish, Sean C. Lema, Gabrielle A. Nevitt Sep 2006

Testing An Ecophysiological Mechanism Of Morphological Plasticity In Pupfish And Its Relevance To Conservation Efforts For Endangered Devils Hole Pupfish, Sean C. Lema, Gabrielle A. Nevitt

Biological Sciences

Imperiled species that have been translocated or established in captivity can show rapid alterations in morphology and behavior, but the proximate mechanisms of such phenotypic changes are rarely known. Devils Hole pupfish (Cyprinodon diabolis) are endemic to a single desert pool and are characterized by a small body, large head and eyes, and lack of pelvic fins. To lessen the risk of extinction, additional populations of C. diabolis were established in artificial refuges. Yet, pupfish in these refuges rapidly shifted to a larger body, smaller head and eyes, and greater body depth. Here we examined how food availability and temperature ...


Changes In Ventilatory Threshold At High Altitude: Effect Of Antioxidants, Andrew W. Subudi, Kevin A. Jacobs, Todd A. Hagobian, Jill A. Fattor, Stephen R. Muza, Charles S. Fulco, Allen Cymerman, Anne L. Friedlander Aug 2006

Changes In Ventilatory Threshold At High Altitude: Effect Of Antioxidants, Andrew W. Subudi, Kevin A. Jacobs, Todd A. Hagobian, Jill A. Fattor, Stephen R. Muza, Charles S. Fulco, Allen Cymerman, Anne L. Friedlander

Kinesiology

Purpose: To investigate the effects of prolonged hypoxia and antioxidant supplementation on ventilatory threshold (VT) during high-altitude (HA) exposure (4300 m).
Methods: Sixteen physically fit males (25 ± 5 yr; 77.8 ± 8.5 kg) performed an incremental test to maximal exertion on a cycle ergometer at sea level (SL). Subjects were then matched on VO2peak, ventilatory chemosensitivity, and body mass and assigned to either a placebo (PL) or antioxidant (AO) supplement group in a randomized, double-blind manner. PL or AO (12 mg of β-carotene, 180 mg of α-tocopherol acetate, 500 mg of ascorbic acid, 100 μg of selenium, and 30 ...


Population Divergence In Plasticity Of The Avt System And Its Association With Aggressive Behaviors In A Death Valley Pupfish, Sean C. Lema Aug 2006

Population Divergence In Plasticity Of The Avt System And Its Association With Aggressive Behaviors In A Death Valley Pupfish, Sean C. Lema

Biological Sciences

Behavioral differences can evolve rapidly in allopatry, but little is known about the neural bases of such changes. Allopatric populations of Amargosa pupfish (Cyprinodon nevadensis) vary in aggression and courtship behaviors in the wild. Two of these wild populations were recently found to differ in brain expression of arginine vasotocin (AVT)—a peptide hormone shown previously to modulate aggression in pupfish. These populations have been isolated for less than 4000 years, so it remained unclear whether the differences in behavior and neural AVT phenotype were evolved changes or plastic responses to ecologically dissimilar habitats. Here, I tested whether these population ...


Analysis Of Treatment Effects On The Microbial Ecology Of The Human Intestine, Anna L. Engelbrektson, Joshua R. Korzenik, Mary Ellen Sanders, Brian G. Clement, Gregory Leyer, Todd R. Klaenhammer, Christopher L. Kitts Aug 2006

Analysis Of Treatment Effects On The Microbial Ecology Of The Human Intestine, Anna L. Engelbrektson, Joshua R. Korzenik, Mary Ellen Sanders, Brian G. Clement, Gregory Leyer, Todd R. Klaenhammer, Christopher L. Kitts

Biological Sciences

A large number of studies have investigated gastrointestinal microbiota and changes in the gastrointestinal community. However, a concern in these studies is how best to assess changes in gastrointestinal community structure. This paper presents two different human trials where the fecal terminal restriction fragment length polymorphism data sets were analyzed to search for treatment effects. Principle components analysis and cluster analysis based on grouped data are compared with analysis of data by subject using distance coefficients. Comparison with baseline within an individual before grouping by treatment provided a clearer indication of treatment effects than did an evaluation of data grouped ...


The Effects Of Dispersal And Recruitment Limitation On Community Structure Of Odonates In Artificial Ponds, Shannon J. Mccauley Aug 2006

The Effects Of Dispersal And Recruitment Limitation On Community Structure Of Odonates In Artificial Ponds, Shannon J. Mccauley

Biological Sciences

I examined the effects of isolation on the structure of both adult and larval dragonfly (Odonata: Anisoptera) communities forming at physically identical artificial ponds over two years. Isolation, whether measured by distance to the nearest source habitat or by connectivity to multiple sources, was significantly negatively related to the species richness of dragonflies observed at and collected in these ponds. These results indicate that dispersal and recruitment limitation acted as filters on the richness of communities at these artificial ponds. The richness of larval recruits in artificial ponds was lower than the richness of adult dispersers observed at ponds, and ...


Acculturation And Breast Density In Foreign-Born, U.S. Chinese Women, Marilyn Tseng, Celia Byrne, Kathryn A. Evers, W. Thomas London, Mary B. Daly Jul 2006

Acculturation And Breast Density In Foreign-Born, U.S. Chinese Women, Marilyn Tseng, Celia Byrne, Kathryn A. Evers, W. Thomas London, Mary B. Daly

Kinesiology

The role of acculturation in the breast cancer risk increase among U.S. Chinese women is unclear. We examined the association between acculturation and breast density in a sample of foreign-born, U.S. Chinese women and examined factors that may explain such an association. Between January 2002 and May 2003, 212 Chinese women were recruited from Philadelphia region screening programs. Cranial-caudal mammographic images were classified into one of four categories ranging from ‘‘entirely fatty’’ to ‘‘extremely dense.’’ Questionnaires assessed information on sociodemographic, cultural, reproductive, and lifestyle factors. An index of acculturation was created based on self-reported English proficiency and within-and ...


Vertical Migration Of The Toxic Dinoflagellate Karenia Brevis And The Impact On Ocean Optical Properties, Oscar Schofield, John Kerfoot, Kevin Mahoney, Mark A. Moline, Matthew Oliver, Steven Lohrenz, Gary Kirkpatrick Jun 2006

Vertical Migration Of The Toxic Dinoflagellate Karenia Brevis And The Impact On Ocean Optical Properties, Oscar Schofield, John Kerfoot, Kevin Mahoney, Mark A. Moline, Matthew Oliver, Steven Lohrenz, Gary Kirkpatrick

Biological Sciences

Vertical migration behavior is found in many harmful algal blooms; however, the corresponding impact on ocean optical properties has not been quantified. A near-monospecific population of the dinoflagellate Karenia brevis was encountered off the west coast of Florida. The community was tracked for 24 hours by following a Lagrangian drifter deployed at the beginning of the experiment. A suite of inherent optical and cellular measurements was made. Over the 24 hour period, the K. brevis population increased during the day with concentrations peaking in the late afternoon (1600 local daylight time) in the upper 2 m of the water column ...

Research Method and Procedures: Participants (N = 2708) were members of the NWCR who enrolled in intermittent years since 1995. Participants had lost an average of 33.1 kg and maintained a 13.6-kg loss for 5.8 years before enrollment. Evaluations of diet and physical activity were conducted at entry into the NWCR and prospectively over 1 year.
Results: From 1995 to 2003, the daily percentage of calories ...


Expression Profiling And Local Adaptation Of Boechera Holboellii Populations For Water Use Efficiency Across A Naturally Occurring Water Stress Gradient, Charles A. Knight, Heiko Vogel, Juergen Kroymann, Alice Shumate, Hanneke Witsenboer, Thomas Mitchell-Olds Apr 2006

Expression Profiling And Local Adaptation Of Boechera Holboellii Populations For Water Use Efficiency Across A Naturally Occurring Water Stress Gradient, Charles A. Knight, Heiko Vogel, Juergen Kroymann, Alice Shumate, Hanneke Witsenboer, Thomas Mitchell-Olds

Biological Sciences

We studied the physiological basis of local adaptation to drought in Boechera holboellii, a perennial relative of Arabidopsis thaliana, and used cDNA–AFLPs to identify candidate genes showing differential expression in these populations. We compared two populations of B. holboellii from contrasting water environments in a reciprocal transplant experiment, as well as in a laboratory dry-down experiment. We continuously measured the water content of soils using time domain reflectometery (TDR). We compared populations for their water use efficiency (WUE), root/shoot ratios (R:S) and leaf mass per unit area (LMA) in the field and in the laboratory, and identified ...


The Effects Of Carotenoid And Food Intake On Caudal Fin Regeneration In Male Guppies, Gita R. Kolluru, N. C. Ruiz, N. Del Cid, Eric Dunlop, Gregory F. Grether Apr 2006

The Effects Of Carotenoid And Food Intake On Caudal Fin Regeneration In Male Guppies, Gita R. Kolluru, N. C. Ruiz, N. Del Cid, Eric Dunlop, Gregory F. Grether

Biological Sciences

The trade‐offs involved in allocating carotenoid pigments and food to healing and regrowing damaged caudal fin tissue v. other functions were examined in guppies Poecilia reticulata, a species in which females prefer males that display larger amounts of carotenoids in their skin. The guppies were derived from four natural populations in Trinidad that differed in resource availability but not predation intensity. Carotenoids, food and site of origin did not affect either absolute or relative fin regrowth, which suggested that fin regeneration in guppies was not constrained by carotenoid availability. It is possible that carotenoid intake influences fin regeneration in ...


Interactions Between Energy Surplus And Short-Term Exercise On Glucose And Insulin Responses In Healthy People With Induced, Mild Insulin Insensitivity, Todd A. Hagobian, Barry Braun Mar 2006

Interactions Between Energy Surplus And Short-Term Exercise On Glucose And Insulin Responses In Healthy People With Induced, Mild Insulin Insensitivity, Todd A. Hagobian, Barry Braun

Kinesiology

Short-term exercise can enhance insulin action, but the effect may be negated by the opposing action of energy surplus. The purpose of this investigation was to test the hypothesis that a single exercise bout would increase insulin action, even when opposed by a concurrent energy surplus. After 2 days in energy balance without exercise, baseline glucose and insulin areas under the curve and the insulin sensitivity index (C-ISI) were measured during an oral glucose tolerance test in 9 healthy, habitually active subjects (6 males, 3 females). A state of relative insulin insensitivity was then induced by systematic overfeeding (OF) to ...

Development Of Successful Sex Determination Method Of Bovine Embryos Utilizing Embryo Biopsy And Pcr, William E. Plummer, Debbie Beckett Feb 2006

Development Of Successful Sex Determination Method Of Bovine Embryos Utilizing Embryo Biopsy And Pcr, William E. Plummer, Debbie Beckett

Animal Science

Producers of domestic livestock strive to improve genetic influences in their herds. This requires identification, and propagation of animals that demonstrate desirable characteristics. The more animals available from which to select, the greater the opportunity to discover high-performance animals. Predetermination of the sex of offspring would provide a greater number of males or females from which to select the top individuals that will contribute the genetics to the next generation. Many attempts at sexing semen and identification of sex in preimplantation embryos have been mildly successful. However, recent advances in gene amplification enable investigators to use sex-specific probes to determine ...


Cytokine Response At High Altitude: Effects Of Exercise And Antioxidants At 4300 M, Todd A. Hagobian, Kevin A. Jacobs, Andrew W. Subudhi, Jill A. Fattor, Paul B. Rock, Stephen R. Muza, Charles S. Fulco, Barry Braun, Ann Grediagin, Robert S. Mazzeo, Allen Cymerman, Anne L. Friedlander Feb 2006

Kinesiology

Purpose: This study tested the hypothesis that antioxidant supplementation would attenuate plasma cytokine (IL-6, tumor necrosis factor (TNF)-α), and C-reactive protein (CRP) concentrations at rest and in response to exercise at 4300-m elevation.
Methods: A total of 17 recreationally trained men were matched and assigned to an antioxidant (N = 9) or placebo (N = 8) group in a double-blinded fashion. At sea level (SL), energy expenditure was controlled and subjects were weight stable. Then, 3 wk before and throughout high altitude (HA), an antioxidant supplement (10,000 IU β-carotene, 200 IU α-tocopherol acetate, 250 mg ascorbic acid, 50 ...


High-Risk Human Papilloma Virus Infection Decreases The Frequency Of Dendritic Langerhans’ Cells In The Human Female Genital Tract, Rafael Jiménez-Flores, Rene Mendez-Cruz, Jorge Ojeda-Ortiz, Rebeca Muñoz-Molina, Oscar Balderas-Carrillo, Maria De La Luz Diaz-Soberanes, Serge Lebecque, Sem Saeland, Adrian Daneri-Navarro, Alejandro Garcia-Carranca, Stephen E.

Ullrich, Leopoldo Flores-Romo

Dairy Science

Dendritic cells (DC) are often arranged in planar layers in tissues with high antigenic exposure, such as skin and mucosae. Providing an en face view, this arrangement optimizes in situ analysis regarding morphology (even of individual dendrites), topographic distribution (regular/clustered) and quantification. The few reports on human genital DC usually utilize single markers and conventional sections, restricting immunolabelling only to cell parts sectioned by the cut. To better assess DC in situ, we labelled epithelial sheets, prepared from fresh cervix biopsies, with antibodies to major histocompatibility complex (MHC)-CII, CD1a and Langerin, revealing (with each of these markers) a ...


The Impacts Of Climate Change In Coastal Marine Systems, Christopher D.G. Harley, A. Randall Hughes, Kristin M. Hultgren, Benjamin G. Miner, Cascade J.B. Sorte, Carol S. Thornber, Laura F. Rodriguez, Lars Tomanek, Susan L. Williams Jan 2006

The Impacts Of Climate Change In Coastal Marine Systems, Christopher D.G. Harley, A. Randall Hughes, Kristin M. Hultgren, Benjamin G. Miner, Cascade J.B. Sorte, Carol S. Thornber, Laura F. Rodriguez, Lars Tomanek, Susan L. Williams

Biological Sciences

Anthropogenically induced global climate change has profound implications for marine ecosystems and the economic and social systems that depend upon them. The relationship between temperature and individual performance is reasonably well understood, and much climate-related research has focused on potential shifts in distribution and abundance driven directly by temperature. However, recent work has revealed that both abiotic changes and biological responses in the ocean will be substantially more complex. For example, changes in ocean chemistry may be more important than changes in temperature for the performance and survival of many organisms. Ocean circulation, which drives larval transport, will also change ...


Effects Of A Marginal Zinc Diet On Intestinal Health And Immune Function, Daniel G. Peterson, James P. Mcclung, Angus G. Scrimgeour, Elizabeth A. Koutsos Jan 2006

Effects Of A Marginal Zinc Diet On Intestinal Health And Immune Function, Daniel G. Peterson, James P. Mcclung, Angus G. Scrimgeour, Elizabeth A. Koutsos

Animal Science

Zinc (Zn) is an essential nutrient for overall health and proper immune function, especially within the digestive system, although the specific mechanisms by which it exerts these effects are not well understood. In this study we examined the effects of short term exposure to a marginal Zn diet on the intestinal health and immune function of lipopolysaccharide (LPS) challenged mice through plasma cytokine profiling and histologic evaluation of intestinal tissue sections. Adult male mice were fed a Zn-adequate (30 ppm) or Zn-marginal (3 ppm) diet for 4 wk and then a bacterial challenge was simulated with an intraperitoneal injection of ...
