Gull Egg Mass as a Function of Length and Width

The mass of a Glaucous-winged gull (Larus glaucescens) egg provides a convenient estimation of parental energy allocated towards reproduction. Obtaining accurate mass measurements, however, can be hindered by logistical constraints associated with field research. In this study, I create a mathematical model to estimate egg mass from easily determined measurements of length and width. Egg measurements were collected at a gull colony on Protection Island National Wildlife Refuge, WA. These measurements facilitated the estimation and validation of model parameters. A multi-variable allometric model incorporating both length and width variables provided the best estimation of egg mass

The Private Provision of Public Goods: An Analysis of Homes on Golf Courses

This paper examines the joint production of golf and real estate development. The empirical results of this analysis show that, over time, golf courses are being constructed less for recreational golf and more for contractual assurance of green open space for homes. We believe that this fundamentally provides some evidence that the demand for environmental quality is growing and that markets are increasingly able to find creative contracting mechanisms to satisfy demands for public goods

Enhancing the Future Public Health Workforce Through Competency-Based Student Field Placements

Background: The Public Health Workforce Interest and Needs (PHWINS) 2014 survey from ASTHO (Association of State and Territorial Health Officials) demonstrated a dramatic need for succession planning and retention of the future public health workforce. To address this need, the Region IV Public Health Training Center’s (R-IV PHTC) Pathways to Practice Scholars Program places students from accredited schools and programs of public health into practical field placement positions across eight states. Skill- and competency-based student field placements reinforce the value of working with medically underserved areas/populations (MUA/Ps) through public health agencies. Field placements use adult learning theory through experiential learning to build essential skills from the Council on Linkage (COL) core competencies. Methods: Host agencies include state and local health departments, Area Health Education Centers, primary care settings, and community organizations in one of eight southeastern states serving MUA/Ps. Agencies propose practical projects using COL domains. Proposals are converted to job postings. Once an agency selects a student, the team collaboratively develops a detailed work plan using specific COL competencies. Results: A brief overview of evaluation findings will be shared but are not the focus of this workshop. Evaluation instruments included a pre-survey, work plan, mid-term survey, final evaluation, and alumni survey. Students submit a final report, reflection summary, webinar presentation and/or abstract worthy of submission to a professional conference. Findings demonstrated increases in students’ perceived ability to perform core competencies and future plans to work in MUA/Ps. Conclusions: This program builds leadership and real-world experience in the future workforce while serving immediate needs of public health agencies. The workshop focuses on interactive discussion about processes and tools to create COL competencybased field placement position descriptions and detailed work plans. Participants can engage in dialogue about developing student positions which enhance their work while training the future workforce

Middle School Single-Gender Science Classes: Self-Concept and Discourse Analysis

One southwestern, suburban middle school in the United States implemented a voluntary, single-gender science program. Although other studies have documented the effects of single-gender instruction and recent educational innovations have focused on its benefits, minimal current research has investigated the effects in middle school science classroom contexts. This study indicated that the patterns of discourse differed between single-gender and mixed-gender classes, with single-gender male classes participating in higher levels of discourse than females in middle school single-gender classes. Overall, the self-concept for females was low in science and school performance. The discourse analysis revealed that males and females used higher level utterances when placed in single-gender classrooms

Spatial and Temporal Variation in Brackish Wetland Seedbanks: Implications for Wetland Restoration Following \u3ci\u3ePhragmites\u3c/i\u3e Control

Chesapeake Bay tidal wetlands are experiencing a broad-scale, aggressive invasion by the non-native, clonal grass Phragmites australis. The grass is often managed with herbicides in efforts to restore native plant communities and wildlife habitat. Management efforts, however, can act as a disturbance, resulting in increased light availability, potentially fostering reinvasion from soil seedbanks. If native vegetation establishes quickly from seedbanks, the site should have greater resiliency against invasion, while disturbed sites where native plants do not rapidly establish may be rapidly colonized by P. australis. We surveyed the soil seedbank of three vegetation cover types in five Chesapeake Bay subestuaries: areas where P. australis had been removed, where P. australis was left intact, and with native, reference vegetation. We determined the total germination, the proportion of the seedbank that was attributable to invasive species, the richness, the functional diversity, and the overall composition of the seedbanks in each of the cover types (i.e., plots). After 2 years of herbicide treatment in the P. australis removal plots, vegetation cover type impacted the total germination or the proportion of invasive species in the seedbank. In contrast, we also found that seedbank functional composition in tidal brackish wetlands was not influenced by vegetation cover type in most cases. Instead, plots within a subestuary had similar seedbank functional composition across the years and were composed of diverse functional groups. Based on these findings, we conclude that plant community recovery following P. australis removal is not seed-limited, and any lack of native vegetation recruitment is likely the result of yet-to-be-determined abiotic factors. These diverse seedbanks could lead to resilient wetland communities that could resist invasions. However, due to the prevalence of undesirable species in the seedbank, passive revegetation following invasive plant removal may speed up their re-establishment. The need for active revegetation will need to be assessed on a case-by-case basis to ensure restoration goals are achieved
