Courtship Effort Is A Better Predictor Of Mating Success Than Ornamentation For Male Wolf Spiders, Paul S. Shamble, Dustin J. Wilgers, Katharine A. Swoboda, Eileen Hebets

Eileen Hebets Publications

Female mate choice decisions are often based on a variety of male characteristics, some of which may reflect male quality via condition-dependent trait expression. Here, we explore the condition dependence of a male secondary sexual trait in a wolf spider and examine its influence on female mate choice. In the wolf spider Schizocosa uetzi, mature males possess a multimodal courtship display (visual + seismic) in which they slowly raise and lower their dark colored forelegs. Foreleg color is highly variable among S. uetzi males with respect to both total amount and darkness. Using diet manipulations in conjunction with color …

Condition-Dependent Alternative Mating Tactics In A Sexually Cannibalistic Wolf Spider, Dustin J. Wilgers, Amy C. Nicholas, David H. Reed, Gail E. Stratton, Eileen Hebets

Eileen Hebets Publications

Condition-dependent male mating tactics often involve high-quality males capitalizing on the outcome of intersexual selection, whereas low-quality males use behaviors that circumvent female choice to achieve copulation. In the wolf spider Rabidosa punctulata, males display 2 distinct mating tactics: 1) “courtship”—consisting of visual and seismic components or 2) “direct mount”—consisting of males grappling/holding females until they assume a copulatory posture. We tested for condition-dependent tactic expression using both field-collected individuals (representing natural variation in body mass and condition) and individuals whose diet we manipulated in the laboratory (representing extreme divergences in body size and condition). Across both natural and …

Cream: A European Project On Mechanistic Effect Models For Ecological Risk Assessment Of Chemicals, Volker Grimm, Roman Ashauer, Valery E. Forbes, Udo Hommen, Thomas G. Preuss, Annette Schmidt, Paul Van Den Brink, Jörn Wogram, Pernille Thorbek

Valery Forbes Publications

Examples that clearly demonstrate the power of mechanistic effect models (MEMs) for risk assessment are urgently needed, and industry, academia, and regulatory authorities across Europe need scientists that are trained in MEMs, principles of ecotoxicology, and regulatory risk assessment.

To meet these needs, Chemical Risk Effects Assessment Models (CREAM), a European project including 20 Ph.D. and three postdoctoral projects, has been launched for September 2009 and will last for 4 years. CREAM is a “Marie Curie Initial Training Network (ITN)” funded by the European Commission within the 7th Framework Programme. ITNs are part of the commission’s “People” Programme and focus …

The Potential For The Use Of Agent-Based Models In Ecotoxicology, Christopher J. Topping, Trine Dalkvist, Valery E. Forbes, Volker Grimm, Richard M. Sibly

Valery Forbes Publications

This chapter introduces ABMs, their construction, and the pros and cons of their use. Although relatively new, agent-based models (ABMs) have great potential for use in ecotoxicological research – their primary advantage being the realistic simulations that can be constructed and particularly their explicit handling of space and time in simulations. Examples are provided of their use in ecotoxicology primarily exemplified by different implementations of the ALMaSS system. These examples presented demonstrate how multiple stressors, landscape structure, details regarding toxicology, animal behavior, and socioeconomic effects can and should be taken into account when constructing simulations for risk assessment. Like ecological …

The Amphipod Orchomenella Pinguis — A Potential Bioindicator For Contamination In The Arctic, Lis Bach, Valery E. Forbes, Ingela Dahllöf

Valery Forbes Publications

Indigenous organisms can be used as bioindicators for effects of contaminants, but no such bioindicator has been established for Arctic areas. Orchomenella pinguis is a benthic amphipod, ubiquitous in the Arctic and can be found in high numbers. We collected O. pinguis at sites with different contamination levels. Population characteristics (body length distribution, average dry weight and amphipod organic content) were related to sediment contaminant concentrations, in order to identify suitable endpoints for using this species as a bioindicator. We show that O. pinguis was prevalent in both clean and contaminated areas, easy to sample and that its population characteristics …

Becoming Physically Active After Bariatric Surgery Is Associated With Improved Weight Loss And Health-Related Quality Of Life, Dale S. Bond, Suzanne Phelan, Luke G. Wolfe, Ronald K. Evans, Jill G. Meador, John M. Kellum, James W. Maher, Rena R. Wing

Kinesiology and Public Health

The purpose of this study was to determine whether pre- to postoperative increases in physical activity (PA) are associated with weight loss and health-related quality of life (HRQoL) following bariatric surgery. Participants were 199 Roux-en-Y gastric bypass (RYGB) surgery patients. The International Physical Activity Questionnaire (IPAQ) was used to categorize participants into three groups according to their preoperative and /1-year postoperative PA level: (i) Inactive/Active (<200-min/week/≥200-min/week), (ii) Active/Active (≥200-min/week/greater ≥200-min/week) and (iii) Inactive/Inactive (<200-min/week/<200-min/week). The Medical Outcomes Study Short Form-36 (SF-36) was used to assess HRQoL. Analyses of covariance were conducted to examine the effects of PA group on weight and HRQoL changes. Inactive/Active participants, compared with Inactive/Inactive individuals, had greater reductions in weight (52.5 ± 15.4 vs. 46.4 ± 12.8 kg) and BMI (18.9 ± 4.6 vs. 16.9 ± …

Dietary Patterns And Colon Cancer Risk In Whites And African Americans In The North Carolina Colon Cancer Study, Jessie A. Satia, Marilyn Tseng, Joseph A. Galanko, Christopher Martin, Robert S. Sandler

Kinesiology and Public Health

We examined associations of dietary patterns with colon cancer risk in African Americans and Whites from a case-control study in North Carolina. Incident colon cancer cases, 40 to 80 yr (n = 636), and matched controls (n = 1,042) were interviewed in person to elicit information on potential colon cancer risk factors. A validated food frequency questionnaire adapted to include regional foods captured diet over the year prior to diagnosis (cases) or interview date (controls). Three meaningful intake patterns were identified in both Whites and African Americans: “Western-Southern,” “fruit-vegetable,” and “metropolitan.” Compared to the Western-Southern pattern, the fruit-vegetable and metropolitan …

Dairy Intake And 1,25-Dihydroxyvitamin D Levels In Men At High Risk For Prostate Cancer, Marilyn Tseng, Veda Giri, Deborah Watkins-Bruner, Edward Giovannucci

Kinesiology and Public Health

Objective Dairy food intake has been associated with prostate cancer in previous work, but the mechanism by which this occurs is unknown. Dairy calcium may suppress circulating levels of potentially cancer-protective 1,25-hydroxyvitamin D (1,25(OH)2D). We examined the associations of dairy, milk, calcium, and vitamin D intake with plasma 1,25(OH)2D levels among 296 men (194 black, 102 non-black) enrolled in a high risk program for prostate cancer from 10/96 to 10/07. Methods All participants completed diet and health history questionnaires and provided plasma samples, which were assessed for levels of 25-hydroxyvitamin D and 1,25(OH)2D. We used multivariate linear regression to examine …

Mechanisms Underlying The Association Between Breastfeeding And Obesity, Cynthia J. Bartok, Alison K. Ventura

Kinesiology and Public Health

Decades of epidemiological research have established that breastfeeding is associated with a modest reduction in risk of later overweight and obesity. However, no systematic effort has been made to delineate the mechanisms that may explain this association. This review summarizes evidence from a variety of disciplines to understand the potential mechanisms underlying this association. One possibility is that this association is spurious and that confounding factors fully or partially explain this association. Additionally, breastfeeding could confer protection by: encouraging the infant's emerging capabilities of self-regulation of intake; reducing problematic feeding behaviors on the part of caregivers that interfere with the …

Hydrothermal And Thermal Time Models For The Invasive Grass, Arundo Donax, Anthony Graziani, Scott J. Steinmaus

Biological Sciences

Controlled laboratory and field experiments were performed to determine the developmental response to temperature and moisture of Arundo donax, a riparian invasive grass and potential bioenergy crop. A logistic function was parameterized and used to predict thermal times to sprouting and the nine-leaf stage. Consistent estimates of the base temperature (T_b) and base water potential (ψ_b) below which development ceases were obtained from various statistical and mathematical analyses. Estimates of T_b and ψ_b were 12.7 ± 1.7 °C and −1.56 ± 0.43 MPa, respectively, for the median fraction of sprouting rhizomes. Median …

Genome Size As A Predictor Of Guard Cell Length In Arabidopsis Thaliana Is Independent Of Environmental Conditions, Barry H. Lomax, F. Ian Woodward, Ilia J. Leitch, Charles A. Knight, Janice A. Lake

Biological Sciences

• The recent discovery of a strong positive relationship between angiosperm genome size and stomatal guard cell length (GCL) opens the possibility of using plant fossil guard cell size as a proxy for changes in angiosperm genome size over periods of environmental change.
• The responses of GCL to environmental stimuli are currently unknown and may obscure this predictive relationship.
• Here, we investigated the effects of environmental variables (atmospheric CO₂, drought, relative humidity, irradiance, ultraviolet radiation and pathogen attack) on GCL in the model plant Arabidopsis thaliana to quantify environmentally induced variation.
• GCL responded to all …

Food Availability And Parasite Infection Influence Mating Tactics In Guppies (Poecilia Reticulata), Gita R. Kolluru, Gregory F. Grether, Eric Dunlop, Sandra H. South

Biological Sciences

Despite the important effects of diet and parasite infection on male reproductive behavior, few studies have simultaneously addressed their influence on intrasexual selection (male–male competition). We examined the synergistic effects of 2 naturally varying environmental factors, lifetime food intake and infection, with the monogenean parasite Gyrodactylus turnbulli on the mating tactics and foraging behavior of male guppies (Poecilia reticulata). We allowed fish to interact directly with each other during observations and found that unparasitized males won more intermale contests, courted females more frequently, and received positive responses to courtship displays more frequently than males that had been infected. …

Group Feeding For The Lactating Cow, Anthony Joseph Martin

Dairy Science

Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …

Effects Of A Large Fishing Closure On Benthic Communities In The Western Gulf Of Maine: Recovery From The Effects Of Gillnets And Otter Trawls, Raymond E. Grizzle, Larry G. Ward, Larry A. Mayer, Mashkoor A. Malik, Andrew B. Cooper, Holly A. Abeels, Jennifer K. Greene, Melissa A. Brodeur, Andrew A. Rosenberg

Biological Sciences

The recovery of benthic communities inside the western Gulf of Maine fishing closure area was evaluated by comparing invertebrate assemblages at sites inside and outside of the closure four to six years after the closure was established. The major restriction imposed by the closure was a year-round prohibition of bottom gillnets and otter trawls. A total of 163 seafloor sites (similar to half inside and half outside the closure) within a 515-km(2) study area were sampled with some combination of Shipek grab, Wildco box corer, or underwater video. Bottom types ranged from mud (silt and clay) to boulders, and the …
