The Trayless Dining Movement and the University\u27s Future Transition

Across the globe, and in the United States, food waste causes negative financial, environmental, and social impacts (Plano, 2016). At the United States retail and consumer level, 90 billion pounds of food are wasted each year, which is equivalent to $161.6 billion annually (Plano, 2016). More than 50% of waste is diverted to landfills where the organic matter contaminates soil and groundwater, decomposes, and produces methane (Lopez et al., 2016). Methane, a greenhouse gas, is more potent than CO2 as it traps 25 times more radiation than CO2 (Lopez et al., 2017). Poster prepared for the Environmental Studies Senior Seminar/Geography Capstone

Waste Reduction at the University of Richmond: Recommendations for a Greener, Cleaner Campus

Connecting with the University of Richmond goals of stewardship and academic achievement both in and outside the classroom, we have constructed a plan for making the University campus more sustainable. By applying knowledge acquired throughout our Environmental Studies education, and understanding its connection to global issues, we hope to make a positive, lasting impact on our campus community. In the 2017 Strategic Plan, the University describes a vision of modelling the way that colleges and universities can effectively meet the challenges of our time (UR Strategic Plan, 2017). Although there is a broad range of environmental issues that can be addressed by universities, we focus on a solution to address food waste on the University of Richmond campus.

Deer–vehicle collision prevention techniques

Every year in the United States approximately 1.5 million deer–vehicle collisions (DVCs) occur resulting in \u3e29,000 human injuries, \u3e200 human fatalities, 1.3 million deer fatalities, and \u3e1 billion dollars worth of property damage. Despite the magnitude of this problem, there are relatively few well-designed studies that have evaluated techniques that can be used to reduce DVCs. Techniques to reduce DVCs fall into 4 categories: reducing the number of deer (Odocoileus spp.), reducing the number of vehicles, modifying deer behavior, and changing motorist behavior. Techniques to reduce the number of deer include decreasing the deer population or excluding deer from the roadway. Techniques used to change motorist behavior include reducing vehicle speed or increasing motorists’ ability to see deer. Modifying deer behavior includes making the roadside less attractive to deer or frightening deer away from the roadway. Despite a limited amount of data, multiple studies have shown properly installed and maintained fences combined with wildlife crossings to be the most effective method of reducing DVCs. Methods with unproven effectiveness include: intercept feeding, repellents, reduced speed limits, caution signs, and roadway lighting. Stimuli designed to frighten deer (e.g., deer whistles, flagging, and deer reflectors) are ineffective because they cannot be perceived by deer or do not elicit a flight response. Well-designed studies are needed so that we can acquire the knowledge about how to reduce the frequency of DVCs

Natality of Yearling Coyotes in West Virginia

Minimal information is available regarding the reproduction of coyotes (Canis latrans) in the Mid-Atlantic region, which includes the states of Delaware, Maryland, North Carolina, Pennsylvania, Virginia, and West Virginia. Since reproductive information is useful to assess populations and determine management strategies and because this information is unavailable for the Mid-Atlantic, we examined uterine tracts of 66 female coyotes collected from February to May 2010 for fetuses. We measured fetuses using a digital caliper and approximated dates of conception and parturition. Nine (13.6%) female coyotes were pregnant with visible fetuses; seven of these females were yearlings (1.5–2.5 y old). Average litter size of yearling coyotes was 5.4 (SE=0.48). We estimated an average conception date of 2 February and an average parturition date of 6 April. Conception and parturition dates were within the reported range for coyotes, though one female successfully bred in early January, which is earlier than reported in the literature. The relatively high proportion (30.4%) of yearling females breeding in West Virginia may reflect abundant food resources, low density of coyotes, increasing human-caused mortality, or a combination of these factors. Reproductive information reported here will be helpful in monitoring coyote population trends and in the assessment of management strategies

The application of ground-based and satellite remote sensing for estimation of bio-physiological parameters of wheat grown under different water regimes

Remote sensing technologies have been widely studied for the estimation of crop biometric and physiological parameters. The number of sensors and data acquisition methods have been increasing, and their evaluation is becoming a necessity. The aim of this study was to assess the performance of two remote sensing data for describing the variations of biometric and physiological parameters of durum wheat grown under different water regimes (rainfed, 50% and 100% of irrigation requirements). The experimentation was carried out in Policoro (Southern Italy) for two growing seasons. The Landsat 8 and Sentinel-2 images and radiometric ground-based data were acquired regularly during the growing season with plant biometric (leaf area index and dry aboveground biomass) and physiological (stomatal conductance, net assimilation, and transpiration rate) parameters. Water deficit index was closely related to plant water status and crop physiological parameters. The enhanced vegetation index showed slightly better performance than the normalized difference vegetation index when plotted against the leaf area index with R2 = 0.73. The overall results indicated that the ground-based vegetation indices were in good agreement with the satellite-based indices. The main constraint for effective application of satellite-based indices remains the presence of clouds during the acquisition time, which is particularly relevant for winter-spring crops. Therefore, the integration of remote sensing and field data might be needed to optimize plant response under specific growing conditions and to enhance agricultural production
